Bearing seats, at the ends of driven roller, are installed inside the rack slide and connected with the two synchronous piston rods of hydraulic cylinders. As to the distance between rollers, it has to meet the following demands. For different materials, demands for the roller distance are different, too.

During the working process of double toothed roll crusher, you need to keep the stability of fuel size and timely adjust the roller distance. What's more, you should make the pressure sufficient. Due to the leakage of hydraulic system or overflow of safety valve, working pressure will go down. When pressure is reduced to the minimum degree, you should immediately supplement the pressure. 

When objects like iron briquettes enter into the roller distance, roller crusher will be overloaded. To protect the dynamo and hydraulic system from being damaged, protector for iron release in roller crusher should play the role of removing foreign matters like iron briquettes. Surprises for you on website of FTM Crusher Company!
