— As material falls into the chamber, the moving jaw compresses toward the fixed jaw to crush the rock between its heavy plates. As the stone is repeatedly compressed, its composition fractures and falls apart, falling through the chamber as it becomes smaller and smaller. The final output size is determined by a preset crushing …

Many people usually ask if driving at a low RPM is recommended. Under normal driving circumstances, driving at low RPM may not cause damage to the car engine. When driving at a low RPM, your car engine does a lot of work to get the car up to speed. It will cause the temperatures for both the car engine and cylinder to rise.
