Combination crusher is optimized adjustable fine-crushing equipment without screen strip, which is designed on the basis of absorbing the advanced crushing equipment technology at home and aboard. Combination crusher can be widely applied to the fine crushing operations in cement plant, fine-crushing process of clinker or medium hardness materials such as dolomite, flint, lead and zinc, serpentine, blast furnace slag, coal gangue and phosphate rock, especially for crushing artificial sand such as hard limestone, dolomite, granite, basalt or highway pavement stone.
Reasons and solutions for combination crusher motor damage
The mechanical operation and electric control of combination crusher are relatively simple (in particular for low-power type), and generally are independent single-unit work, so it is hard to handle problems timely, and repetition frequency of problems is increased.
Improve force status of bearing.
Impact load working on bearing depends on the impulse acting on the rotor and support flexibility of bearing. Increasing bearing support flexibility will reduce impact load working on the bearings. So we add a rubber sheet with appropriate thickness between the bearing and the support frame in order to improve the bearing support flexibility. The rubber sheet and increased support flexibility absorb part of the vibrational energy to improve the bearing force status and achieve the purpose of extending combination crusher service life.
