Sand production efficiency is improved by nearly 30%
Quartz sand refers to the quartz products whose general fineness is within 120Mesh after being proceeded.
The use of quartz sand: to manufacture glass, refractories, smelting ferrosilicon, metallurgical flux; it also used to make concrete acid and acid-resistant mortar by its strong acid medium erosion ability in building.
The selection of quartz sand production equipment will directly affect the product quality and investment on processing system. Selection is based on the characteristics of the raw materials. The main part of quartz sand crusher device is crushing equipment.
We can combine various types of equipment depending on the process requirements to meet customer's different process requirements.
Quartz is firstly crushed by coarse crusher, then the coarse materials are transported by belt conveyor to the fine crusher for further crushing; crushed quartz stones are divided into two kinds of stones through screening: the one meets the sand maker feed size stones are sent to sand washer and the other are sent to be re-crushed.
Quartz sand production equipment should be given priority to ease of operation, reliable operation, energy consumption and low cost of operation and management.
Zhengzhou Hongxing quartz sand production line is of high automation degree, low operating costs, high crushing rate, energy saving, large output, less pollution, easy maintenance; its production is in line with national standards for building sand, size is uniform, grain shape is good, and gradation is reasonable; it is widely used in cement limestone, clinker, brick, shale, coal gangue, coke, metallurgical, glass, coal, mining ore crushing industry.
Mechanism sand promotes the development of crusher
With the continuous advancement of science and technology, industrial production is increasingly relying on mechanical efficiency and convenience, especially in the gravel production. The gravel aggregate is an inseparable part of the construction project, it promotes modern reinforced concrete buildings to erects, and the flat road to extend in all directions--the sand and gravel industry has made tremendous contribution for the economic construction. The sand and gravel industry is a long history industry, now, the sand and gravel industry has become one of the basic industries supporting the national modernization.
The traditional way to produce sand and gravel is very backward, especially before the reform and opening up, China's economic development was lagging behind, economic policy was austerity, and the construction of infrastructure was in a phase of stagnation. In modern society, the pursuit of production efficiency asks people begin to increasingly focus on the benefits of sand maker in the gravel production. The mechanism sand begins to be used instead of the traditional river sand by its advantages. Mechanism sand can achieve unified specifications according to different demands and avoid the waste so the market is very broad. In the last few years, due to the economic development destroyed ecological balance, the state vigorously promote environmental protection and ecological balance protection, environmental support policies on the sand and gravel industry greatly stimulates the development of mechanisms sand.
The boom of the mechanism sand will drive the development of crusher market. From the development trend of crusher industry, improve the performance and adaptability of the working environment is a major trend. Under the situation of the state is vigorously promoting infrastructure construction, crusher industry in China should seize the broad market and improve their level, make good use of opportunity to improve the ability of independent R & D and innovation so that improve the international competitiveness of crusher product.
Sand maker helps the development of crusher industry
At present, the manufacturing level of crusher equipment has entered the international ranks. Faced with vigorous large-scale development of the western region, high-speed railway and urbanization process, sand makers play an important role, not only protecting the market demand for sand and gravel aggregate, but also leading the innovation reform in crusher industry.
Vertical shaft impact crusher, also known as sand making machine, is efficient and high-quality equipment innovatively researched and developed combining the actual domestic situation and international advanced level in various fields; it can be used for both coarse crushing and fine crushing, having advantages of high crushing efficiency, unique structure, flexible operation, less dust, energy saving and environmental protection; applicable to the construction facilities, artificial sand, cement and other fields.
New sand maker alters the traditional manufacturing process, became the indispensable aggregate equipment in gravel aggregate industry. Under the promotion of infrastructure construction climax, strengthen management in upgrading technology, enhancing product quality and stabilizing performance can make the device toward the development of automated and intelligent direction, and also, open up a new road to produce sand and gravel aggregate, which meet the broad needs of the market.

As a professional manufacturer of crusher industries, Hongxing continues to introduce new technology, painstakingly research and develop new high efficiency sand maker so as to strengthen the awareness of independent innovation and open up the booming development for future crusher industry.
Mechanism sand brings opportunities for crusher industry
As we all know, the gravel is an integral part of aggregates in construction projects—both modern reinforced concrete buildings and the flat highway cannot be separated from the sand and gravel industry. Sand and gravel industry is an industry with long history, now, the sand and gravel industry has become one of the basic industries supporting the national modernization. With the continuous advancement of science and technology, industrial production is increasingly relying on mechanical efficiency and convenience, especially seen in the gravel production.
In the past years, China's economic development lagged behind, traditional ways used for the production of sand and gravel were very backward, economic policy was constrictive, infrastructure construction were stagnant, the demand of sand was small and accordingly sand and gravel resources were abundant. And the origin of the sand and gravel often lied in remote mountainous areas or river basins, most of which relied on human production with intense labor and high energy consumption. With the pursuit of production efficiency in modern society, people increasingly focus on the benefits of the crusher in the gravel production and so, the advantageous mechanism sand instead of the traditional river sand. Mechanism sand can be achieved unified specifications according to demands, avoiding the waste caused by different specifications of traditional river sand in the using process; therefore, it has very broad market.
In recent years, the destruction of the ecological balance caused by economic development is more and more obvious, the country vigorously promote environmental protection and ecological balance protection, as well as putting forward support policy to environmental sand industry, which greatly stimulate the development of mechanisms sand. From the development trend of mechanism sand industry, in order to seize the broad market, China's ore crushing industry should take advantage of the country’s support of the machinery and equipment manufacturing, improve the quality and efficiency of sand maker and ball mill to improve the international competitiveness of crusher product.
Hongxing machinery will actively respond to the call of national policy, try its best to improve itself and support national construction！
Detailed introduction of Hongxing sand washer
As the major manufacturer of mine crusher ,grinding mill and sand-making machine ,Hongxing have developed various kinds of products according to the various crushing requirements .And we should have a general knowledge of the sand-making requirements when we want to choose the quality sand-making equipment .
After years'research and development of the sand-making equipment ,Hongxing have found the particle requirement of the crushing materials is fine .And generally speaking , the materials with needle shape will become more easily be grinded while the stone crushing will have a strict requirement for the particle size .And the reason for this is that the cubic sand will have the edges and corners ,which will cause a interact locking effect .While the continuous movement will create the great reduction and the cubic sand will cover a larger space than the round sand ,which will reduce the movement capability of the asphalt ,materials and cement .

Main factors that affect sand washer production
Our sand washer industry has indeed made remarkable achievements. Especially in recent years, sand washer enterprises pay more attention to the new product research and development, the construction of sales channels and the application of e-commerce. Although the sand washer industry has gradually become mature after the financial crises in 2010, the market was not always smooth. Due to the continuous pressure of the raw materials and the human resources cost, as well as the influence of the real estate market, domestic sand washer industry is facing unprecedented sales crisis.
As the professional manufacture of sand washer, Henan Hongxing Mining Machinery will talk about the main factors affecting the production of sand washer based on our years of experience:
First, the content of sand soil
The original sand quality will be the decisive factors affecting the output of sand washing. The quantity of mud, stone, shell and other impurities, the size of particles will affect the output of sand washer.
Second, the proficiency of operation
The operators will also affect the production of sand washing. It is necessary to train the operators before using the sand washer. The operator must understand the working principle, performance characteristics and other precautions.
Third, the maintenance level of equipment
Sand washer should be regularly maintained so as to maintain a good working condition, which is the premise of guaranteeing production.
Fourth, the quality of sand washer
Any equipments' operation result is closely related to the quality of equipment itself. As is well known, the same product may bring us different experience and value for the different quality.
For the domestic sand washer which is always considered as no brand, this is a problem whether to actively attack or defend to meet this crisis. Whether has the brand became an unprecedented bottleneck? The whole brand of China sand washer need to promotion especially for the raw materials and the design. Why does the the development of brand improve slowly? I think the Chinese is still relatively conservative. To establish a famous brand not only needs the courage, but also the capital, of course, does not rule out other external factors.
The latest Mobile crushing station, and new type cone crusher of Henan Hongxing Heavy Industry Machinery have reached the international advanced level in the technology. The crusher equipments has many customers in the world market. Henan Hongxing Heavy Industry Machinery continues to research and develop the types of crusher and tries to make all crushers to reach the international top level. This happens to coincide with the "12th five year plan".
Equipment used in sand and gravel production line
In the most recent period, the rate of crusher technology innovation has been slow down. Henan Hongxing heavy industry technical staffs have also met with a "bottleneck". In this situation, our chief engineer Xu required the technical staffs transform the research direction. We should suitably strength and improve the performance of crusher. We should research and development high performance and high-end crusher. The development trend of current crushing equipment is "high-end" "high integrated" "high performance" and "low-carbon".
First, the impact crusher has high crushing ratio which can reach over 50, but the crushing ratio of the jaw crusher and cone crusher may hardly reach to 20.
Second, the products particles are excellent. Under impacting action, the material to be crushed of breaks along the most vulnerable level. The probability of the drought cubic form is higher in this selective crushing way. Therefore, the flakiness percentage content of impact crusher can be less than 10%, while the flakiness percentage content of jaw and cone crusher will be more than 15%. These characteristics make impact crusher play an important role in large numbers of crushers.
The new sand maker developed a new wheel sand washing equipment which is especially suitable for smaller coarseness, washing of particles and so on. It is suitable for sand and gravel and can wash the powder and dirt. The innovative structural design and reliable gear can sand of excellent dewatering effect. The new sand maker also suitable for washing, grading, dewatering and cleaning of the metallurgy, building materials and utilities industry.
The hammer developed by Hongxing Mining Machinery is very durable, which eliminates the screening process and use the straight-through sand making sand producing and output stably. It is favored by the old and new customers. Hongxing's good services of exact model selection, installation and guide make you no longer worry about seeking for desirable sand maker.
Besides the products' excellent quality, Henan Hongxing Mining Machinery Co.,Ltd. has provided customs with the complete sets of service system of pre-sale, sale and after-sale and customs can get free site measurement, design and installation. Hongxing heavy industry configurates the process according to customers' production scene strives to provide customers with the most reasonable and economical production line make all customs rest assured.
The advantages of sand maker shown in rotor
After carefully analysing the nature of the sand maker industry, we will find a problem that the industrial structure in the current international machinery industry is unreasonable, which mainly shows that the industrial growth mode is still extensive and the technological innovation can not closely contact with the actual transformation. These above problems have a direct impact the realization of the sustainable development in this industry. If we only analyse these problems form the perspective of policy, we should resolve this contradiction form the followings. The related mining equipment industry must adopt a long-term perspective, lay the basis of endogenous growth and proactively blend in the market competition. However, if we analyse these problems from the point of view of technical improvements, the sand maker industry which need integrate into the newest technology must introduce the advanced production technology on the basis of the advantages of reliable structure, stable work, high efficiency and energy-saving. We should firmly occupy the existing industry market through "good quality" not just the simple sense of "low price". As a generic sand making equipment, the application of the sand maker ranges from the building materials to the chemical, which is very broad.
Hongxing Heavy Industry has summarizes the technical advantages of the new VSI sand maker through a long-term practice of crushing different particle size and materials, analysis and calculation of CAD and finite element, designs and improvement for many times and use for reference of advanced technology.
The advantage is shown in rotor.
a There is a production board made by special and wear-resisting material material outside the upper and lower plates of the rotor, which completely avoids ineffectiveness of the rotor because of the worn bead welding layer out the rotor. It also helps users to avoid great economic loss caused by difficult repair work.
b The design structure of the open rotor can withstand lots of shocks and abrasion of extremely hard materials like corundum and quartz to the rotor.
c The lining and separating cones of high wearing resistance are ensured to use for a long term and avoid to install and dismantle repeatedly.
d The block is of high wearing resistance and long life.
e The rotor can run smoothly with high-speed through dynamic load balancing tests.
Methods to keep sand maker working effectively
As with other ore dressing equipment, sand maker should be given more attention to maintenance when isn't in use for long time. Hereby, we introduce you an economic method, that is dilute hydrochloric acid. However, you should be care that rust things should not immersion too long, or the metal will take chemistry reaction. And other methods, such as ash propel and shot blast are also available. Then I will introduce you related information in details.
At first, chemistry method, as its name, makes use of chemistry reaction to remove rust. We common say it acid dipping, and it can only done in workshop.
Another method is shot blast cleaning. Shot-blasting abrasives and polishing makes use of high-speed rotating impeller throwing grinding materials to the steel surface, so as to achieve the purpose of rust removal. It is a more advanced steel rust method for sand making machine cleaning processing. It is not only high efficiency, but also low cost, high degree of automation, and it is able to implement assembling operation, less environmental pollution, but it only available for indoor operation.
The distributing device of rotating disk crusher is composed of motor, couplings, worm reducer, V belts, feeding tube ad feeding hopper. It can thoroughly mix and uniform all the materials, and make the materials flow stability around the buffer cavity. It can improve the processing capacity, reduce the power consumption, ensure the product size and prolong the service life of lining board.
This machine has unique crushing cavity shape. It contains upper ring cavity, non-broken area, and parallel broken area. Its structure is: in the upper ring cavity, the maximum feeding size is several times than the maximum material size. The height of material must stay in a certain value. The height value depends on the amount of materials in the non-control broken area. While the stability of H value also decide whether it can feed materials quantitatively. Improve and regulate the machinery and equipment management system, establish and improve an appropriate administrative organization; build machinery and equipment statistics system, strengthen unified management, and establish detailed technical files, do regular checks; implement merit system and give full play of operators and maintenance personnel.With the continuous development of modern technology, machinery and equipment are constantly upgrading, which requires the construction and technical staff continue to enhance new knowledge and technology, and scientifically use mechanical equipment.
Solar power helps sand maker be green
The connotation of green technology can be summarized as: the non pollution technology which based on the environment value and the usage of all modern technology potential. Green technology is not only the technology piecemeal but a technology group, which consists of energy technology, material technology, biotechnology, pollution control technology, resource recovery technology, environmental monitoring technology and the series clean production technology.
The green technology is the point that the big enterprises and mining manufactures must pay much attention. During the working process, the environment pollution of the classifier, magnetic separator, belt conveyor, and crusher can reduce to the degree of harmless to people when use the green technology and Optimize production environment .
Sand maker uses the high speed sportive material of mutual crush and fiction between materials. It especially suitable for the coarse crush and fine crusher of the ultrahard, medium hard material and Abrasive materials.
They are two types of feeding methods of sand maker. The first is overflow feeding type, which feeding granularity of impeller is the same. In this condition, the material quantity that feeding to the impeller archive the oeprationatfullload( that is the motor power maximize) when feeding more material, the material will overflow into the outboard of whirling motion chamber impeller. The second is cascade feeding type. When the second feeding granularity is greater than the impeller feeding granularity, the material should be feed in two feeding end. The sand maker of our company was developed on the base of this working principle.
The nuclear power is relevant to nuclear reaction. Changes in the structure of nuclei can release large amounts of energy; this energy is called nuclear energy, commonly known as the Atomic Energy. It comes from nuclear fission of uranium, plutonium stored in the earth’s crust, and nuclear fusion of deuterium, tritium, lithium stored in the ocean. The largest use of nuclear energy is electricity. In addition, it can be also used for other types of power or heat source.
Through the above presentation, we learned that the sand maker can make use of solar power to achieve self-sufficiency in the production. It is entirely feasible. Friends who are interested can call our customer service telephone to get more detailed information.
