1, The hydraulic cone crusher adopts hydraulic protection and hydraulic chamber cleaning, which is convenient for maintenance and short downtime, which greatly reduces the trouble of manual unloading when the original spring cone crusher needs to be closed. 　
　
2, The iron protection device of the hydraulic cone crusher, when the sundries enter the cavity, the protection device will automatically release, and then reset immediately, without affecting the normal operation of the equipment. However, the protection stroke of the spring cone crusher is short, which sometimes causes serious accidents, such as shaft breakage. 

Rusting of the machine is a relatively common problem, but this will make the manufacturer forced to replace the crusher equipment, resulting in a shortage of funds. Here are some tips for rust prevention of counterattack crushers. I hope to help you!

In order to prevent the premature occurrence of rust, corrosion and other problems of the impact crusher, it is very important to strengthen the maintenance of the crusher. The manufacturer will arrange personnel to maintain the crusher on a regular basis. For the parts that are prone to rust, the preservative should be applied regularly. You can also apply anti-oxidation paints such as mineral paints and sprays to prevent iron products from rusting when they come in contact with water and air.

Jaw crushers have the advantages of low noise, simple structure, reliable operation, etc., and are widely used, but often due to irregular operation or long-term component wear and other reasons, the discharge is not up to standard. Let's look at it in detail below:
　　
1, crushing ratio
The crushing ratio refers to the ratio of the imported material to the particle size of the finished product after crushing. The larger the ratio, the larger the crushing ratio, and vice versa. For the production process of the jaw crusher, the larger the crushing ratio is, the pin flake content Therefore, in production, the adjustment of the crushing ratio is an important measure to ensure the discharge. Of course, too small a crushing ratio will not work. This will cause a decrease in the output of the entire system and an increase in the internal circulation, which will increase the wear of the crusher. The choice of ratio needs to be appropriate.

Cone crushers are widely used in mine crushing due to their advantages of large crushing force and high output. The cone crushers produced by Jiaozuo Zhongxin include single-cylinder cone crushers, multi-cylinder hydraulic cone crushers, etc., which can be used Medium and fine crushing production of high hardness materials.
 

Sand making machine is a common fine crushing sand making equipment with simple structure, reliable quality and energy saving. It is one of the indispensable key equipment in mining, metallurgy, building materials, construction and other fields.

The motor is also a motor, and its main function is to generate mechanical drive torque as a power source for the operation of various electrical appliances and machinery. In the crusher equipment, the motor plays a very important role, but for the disassembly of the motor, not everyone will explain the motor disassembly method of the sand making machine.
