Roller crusher: The roller crusher has a simple structure, a compact and lightweight body, reliable operation, easy adjustment of crushing, less over-crushing during crushing, and can crush sticky and wet materials.
The overload protection device is an indispensable part of the roller crusher. Reasonably designed overload protection device marks the reliability and safety of the roller crusher. When the roller crusher is working, due to changes in raw material delivery volume and possible foreign objects (such as iron, stones, etc.), the equipment may be overloaded and damaged. Therefore, the equipment needs to be installed with protective devices.
Roller crusher The compression amount of the disc spring is adjusted on the moving roller to adjust the crushing force of the counter-roller, and an overload protection block is added on the fixed roller to provide safety protection for the roller crusher. This not only increases the roller pressure, but more importantly, the gap between the rollers can be strictly controlled within the range of 2 to 10 mm, which protects the cutting particle size and improves the green body pass rate.
When the machine is working normally, the pressure of the spring should be able to balance the force generated between the two rollers to maintain the gap at the discharge port and make the product particle size uniform. When the crusher enters non-crushed objects, the spring should be compressed, forcing the movable crushing roller to move laterally and the width of the ore discharge opening to increase to ensure that the machine is not damaged. After the non-broken objects are removed, the spring returns to its original shape and the machine works as usual. During the operation of the crusher, the safety spring is always in a vibrating state, so the spring is prone to fatigue damage and must be inspected frequently and replaced regularly.
As a manufacturer of toothed roller crushers and toothed roller crushers, Shanghai Joyal has increased its technological investment in crusher equipment and grinding equipment. The products it produces are stable and reliable and can meet the specific crushing particle size requirements of different users.
