Performance Characteristics of Symons Cone Crusher produced by Shenyang Yekuang:
1 The hydraulic pressure adjusts the discharge opening to make it convenience and accurate.
2 The maze of wiper seal make the lubricating oil clean.
3 The crushing wall of the moving fixed-cone does not need to filling after fine finishing. It is easy and fast to replace.
4 The lubricating system has return oil and temperature protection device, and interlocks with the main motor to prevent the leader broken.
Machine Maintenance:
1 The newly installed tire must be frequently checked because it is easily to become flexible.
2 It is need to pay attention that whether every part works normally.
3 The wear degree of wear parts should be checked and the wearing parts should be replaced.
4 If the oil temperature of bearing goes up, you shall stop at once and eliminate this phenomenon.
