Symons cone crusher spring over-iron protection device

The function of the PSG Symons cone crusher spring is to protect the equipment from being damaged when the crusher enters the unbreakable material (iron block), so the pressure of the spring should be compatible with the crushing force of the cone crusher; The spring does not move during normal operation.

The support sleeve is lifted only when iron blocks fall into the crushing cavity to overload the crusher, and the spring is compressed. Therefore, the locking spring on the cone crusher will cause normal crushing. The force device is also a safety device to protect the crusher from damage when the crusher passes through the iron; therefore, the tightness of the spring (the height after compression) should be adjusted strictly within the range specified in the manual, and the tightness of each group of springs should Adjust to a consistent level.
 
If the spring has been adjusted to the specified tightness, but the support sleeve still bounces frequently, then the reason must be found out, and the method of re-tightening the spring cannot be taken casually to solve it-because the spring is excessively compressed, it will not only make the spring safe The compression process is reduced, and at the same time, the load of the parts is increased. In this way, when entering the non-broken material, it will cause damage to important parts such as the spring screw spindle.
 
If the spring has a normal tightness, but the support sleeve still frequently jumps, there are many possible reasons for this situation: (1) non-broken material has entered the machine (2) uneven or excessive feeding of the ore; feeding of the fine ore in the ore Too many (3) small discharge openings (4) caused by dampness of the mine, blockage of the discharge openings, etc.-therefore, the response should be eliminated, so as to avoid the critical moment of the spring of the PSG cone crusher "fading down".
 
The spring is very important to PSG Symons cone crusher-it is not only the guarantee for the normal and safe operation of the equipment, but also the key to the crusher's "self-decompression".
