First, the use of double toothed roller crusher
After the double toothed roller crusher is put into use, in order to ensure the safe operation and make full use of its best performance, it must be regularly maintained according to the requirements and form a system
1, the crusher must be started without load
2, check the connection of the gear plate every day, do not allow loosening or losing at work. Check the temperature of the bearing regularly. It is not allowed to work at higher than 120 degrees centigrade. When the temperature is higher than 80 degrees, you should check the bearings and other parts
3, the degree of tooth wear is inspected once a day, when the serious wear and tear, should be complete replacement, to ensure that the broken tooth roller shaft running balance
4, regularly check the reducer's oil temperature, oil level and oil pollution, the reducer oil temperature should be less than 90 degrees, and found that the oil temperature is too high, the oil level is too low and oily serious pollution, should be timely inspection, oiling or oil
5, in a timely manner to the hydraulic coupler after injection spray and replacement of the fusible plug.
6, regular inspection of insulation and wiring head connection, cable damage must be replaced; wiring head loose, must be re tightened

4, eliminate the reducer and the connection cover sundry, in order to heat dissipation
5 check all hydraulic hoses and hoses for damage and leakage

Seven, check every face
1 check whether the crusher is damaged or worn
2, check if the reducer needs to be overhauled
3, check if the motor needs to be overhauled
4, check whether the broken tooth has enough life to complete the new surface broken
