Producing crushers follow the step of time

Producing crushers follow the step of time

Through the rapid development of 2010-2011, China impact crusherat last has been stroke by the spread of European economic downturn crisis, in 2012 the sales situation is not optimistic. Whether impact crusher of China could look for other ways out of the sales plight, let's wait to see in the coming 2012.
Overheated economy can be pided into "consumer-driven overheated economy" and "investment-driven overheated economic".
Hongxing Machinery Co., Ltd. has been engaged in the development and production of the crusher for many years; relying on rich production experience, we introduce a series of crusher equipment such as jaw crusher, impact crusher,hammer crusher,  grinding equipment and complete sets of production lines, which popular in the power plants, building materials, grinding industry and other fields by dint of its novel structure, low energy consumption, high efficiency and environmental protection advantages.
The drive current of each roller is set with a limit, when encountering extreme hard or large materials, the roller will reverse automatically when the current overloads to protect the roller shell from getting damaged. The reverse operation is as follows:
1. Under normal conditions, the roller stops with its paired roller on the outside, performing the following actions in the middle of them.
2. The action roller stops for t1 then reverses for t2 to get stopped.
3. For another t1, this pair of rollers re-starts and rotates in normal working status.
4. It will send out an alarming signal when the times of the reverse operation surpass n in t3.
The above procedures are controlled automatically via the program. When it alarms, the maintenance staff should find the problems through the manhole and the observation hole. Then the roll crusher can be re-started after the troubleshooting is completed.
At the time of encouraging the development of energy-saving building materials industry, our country also increase the adjustment of mining machinery, strengthening energy conservation, efficient and environmentally friendly crusher equipment, which will also become the leading direction of the crusher industry in the future. In order to face the strong momentum of building materials industry, Hongxing machinery emphasizes on enhancing product quality and optimizes the product and accessory structures with design principles of long-service- life, low power consumption and easy-to-operate, the productions are characterized of dust extraction, low noise and low energy consumption, and operate efficiently and economically.
