Shanghai Zenith is not merely a ball mill provider in China, but in addition the alternative scheme. Following the ball mill operates for some time, there is some spray orifice around the spray bar that is blocked through the impurities during the oil, at this time, the essential oil stress during the spray orifice rises which prospects for the other orifices unplugged boost in flow chart. The essential oil close to the essential oil slinger will splash out on the essential oil slinger which prospects for the essential oil leakage.
Solutions: dredge the blocked essential oil hole around the spray bar, and verify the ball mill spray bar routinely and thoroughly clean in time when the banked-up spearhead is found. Spend interest to the fact that thoroughly clean the essential oil sprout hole through the gentle texture device to stay away from the hardness product harm
As large amount sales of ball mill, it is still pale into insignificance when compared with the automotive industry. The main research of the combustion engine companies are generally lay on automotive industry because of the relative stable working environment. Therefore, it needs two or more industries working together to solve the matter of energy saving and emission reduce. Industry experts stressed that all of the enterprises should broaden mind actively rather than rely on the only solution of hybrid project. After all, the ball mill machine is not electric toys. Relying on electricity to run machine is only an expedient measure, every way that can contribute to ball mill energy saving should be encouraged. Here is the solution to energy-saving ball mill grinding tail spit ash: jaw crusher:http://www.hx-china.com/1.html
1. To improve the sealing method of grinding head.
2. Reduce the feeding mouth diameter to increase hollow shaft helical blade height.
3, Change the hopper (splice tube) helical blade to be equal spiral distance with the pitch of the hollow shaft helical blade. Add in spiral blade at the inverted cone, so that the material is transported away when into the splice tube. It prevents the material from retention and return in the inverted cone .
4. Improve the cement mill feed side.
5, Make improvements in the operation, such as adjust the grinding grading and loading. Adjust the cyclic loading rate of the powder separator and avoid the positive pressure operation and micro-vacuum operation.
However, there are far more energy saving problems to solve. In powder production line, ball mill does plays an important part and it is the irreplaceable phase in sand making plant. We are ready to work together with you to put forward more constructive ideas for energy saving and environmental protection ball mill.
Ball Millis mainly used to grind materials in mineral, cement, refractory, chemical industry, etc. Ball Mill has dry and wet ways. When dry Ball Mill works, capacity is affected because material flow ability is reduced, so absorbing wind device is needed on the outlet of Ball Mill, and then negative pressure is formed in the Ball Mill to increase flow ability of material, so the capacity is increased.
In fact, whether the ball mill, energy-saving ball mill, large-scale ball mill, or the planet ball mill used in college laboratory, cement ball mill in cement industry, their working principle is similar basically. Therefore, the factors affecting their speed have something in common. The working principle of ball mill is driven by revolution and auto-rotating, crushing the samples by the friction force and percussive force in the grinding warehouse. Generally, discharging grain is in direct proportion to the ball mill speed.
In different mineral industry, the effects of ball mill speed are different. For example, in coal mine industry, the speed of the ball mill is directly influencing the movement condition of the ball and coal sheet. It also influences coal grinding process. If the rotary speed is very low, steel ball and coal sheet cannot be taken up, only the lower mill is rolling, the coal output is small. Instead, if the speed reach high, the centrifugal of the ball and coal is greater than the gravity. The ball and coal sheet will rotate together with the drum, losing the role of grinding coal sheet. Rotary ball mill’ speed can make the ball in the rotary drum achieve maximum hoisting height, and then the ball reach the biggest impact, grinding effect is perfect. However, in ball mill practical work, its speed is limited by transmission device speed and external other conditions. The ball mill is impossible to achieve optimal height; it is generally close to each other. As the professional manufacturer of complete sets of mining machinery, such as cement plant, Henan Hongxing is always doing the best in products and service. impact crusher:http://www.hx-china.com/3.html

Ball mill should be installed in a solid concrete foundation. Filter out the fine material from the overflow tube. The base of the machine adopts a channel, the machine adopts welded steel.
Rotational speed of ball mill will affect the grinding medium?
When other conditions are the same, the grinding medium in the cylinder body movement depends on the ball mill speed. The status of the medium is different, the grinding effect is also different.
Ball mill speed is too low on the production of energy-saving ball mill effects: low speed, medium to cascading movement, shock effect is smaller, the grinding action mainly for grinding, ball mill capacity is low, suitable for fine grinding;
Ball mill speed is too high on the production capacity of impact: energy-saving ball mill at higher speed, throwing motion mode of medium proportion increases, strong impact, grinding to shock, grinding secondly, in favor of crushed course materials, energy-saving ball mill high production capacity. Ball mill with different filling rate, useful power reaches its maximum value when requested by the speed is not the same.
Machinery in most cases is used to manufacture an end product and mineral ball mills are used for the same purpose by grinding. Machines have different mechanism on how they work so that the end product can be achieved. It’s important for anyone who intends to buy mining machine to know how mineral ball mills work.
The cylinder either rotating on its axis or using a cylindrical container rotates at a relatively low speed. This is to allow the balls to cascade or move in the mill base and allowing for the grinding of the material to occur. The rotation according to engineers should happen at twenty revolutions per minute which is highly determined by the diameter of the mill. If the diameter is large then the rotation is slower.
A closed system is preferred to operate the mineral ball mills so as to achieve reasonable efficiency. Over size material is usually and continuously re circulated back to be reduced and the discharge from the ball mills are usually classified using screens, cyclones and air classifiers. To grind the materials to finer powder the speed is usually increased especially if the machinery is using electricity and not fuel to power. This is because controlling becomes easy. there are mineral balls that are used to grind cement and these are usually large and they consume a lot of fuel or electricity cone crusher:http://www.hx-crusher.com/cone_crusher.html
A ball mill mineral machine or a grinder is used in mines to grind material into a fine powder. The grinded materials are in turn used in mineral dressing process such as pyrotechnics, paints and ceramics. It mixes materials like ores and even ceramic raw materials by rotating in a round horizontal axis. The mills are filled half way with the material to be grinded and the grinding medium or product is also put.
There are different sizes of ball mills and the large ones are the ones that rotate on their axis while the smaller ones consisting of a cylindrical container, normally sits on two drive shafts. To transmit the rotary motion using pulley and belts and in different occasion a rock tumbler is also used.
A ball mill mineral can be used to grind both wet and dry products and there are two types of ball mills namely over fall type and grate type depending on the different ways they discharge materials. There are also many types of grinding media and their properties are density, size, composition and hardness.
There is ball mill mineral that is commonly used in laboratories and are called planetary bill mill. They are used to grind materials into smallest size while giving a demonstration to students or manufacturing something by professionals.

What's more we install a hydraulic coupling and opening device to reduce the starting load and protect the motor. Here we will introduce some methods to deal with the bearing problems.
1, surfacing: although there are kinds of surfacing electrode, its price is very high. If you choose inappropriate electrode or use improper measure, it will increase the cost and the difficulty of processing.
2, casement: it needs to calculate the strength and determine the minimum allowable diameter. Because the rotor system needs to be overall disassembled and processed by large-scale lathe. raymond mill:http://www.hxjqchina.com/product-list_22.html
3, thermal spraying: this method needs high conditions, for the spindle is not easy to disassemble, the huge rotor is difficult to achieve the desired preheat temperature. Before turning, please strick the coating by using steel bar and evaluate the bounding strength of coating. The cost of spraying raw materials and turning processing is higher.
4, electric plating: select the right size according to the damaged axis standard, and brush with chromium plating or nickel. The processing time, the cost of raw materials and working hours is higher.
5, sticky coating: this process save time, manpower and coast. The thickness can be from dozens of microns to dozens of millimeters. But it should select accurate industrial repairing adhesive. It can basically meet the maintenance needs.
Through the above introduction we can see that the sticky coating process has good effect and saves time and effort, which has been selected by the majority of crusher manufacturers.
Hongxing can customize various types of rotors in line with actual crusher types and clients’ requirements to be applied for various hammer crushers. Crusher Rotor is the key component of crusher. After long time use, the hammer pin is likely to be out of shape, and the hammer plate and hammerhead are likely to break. All these problems have been completely solved.
