Impact crusher sand making sand making mechanical efficiency of a sand system equipment, since the production technology introduced from abroad, Our Industrial constant structure and production process, such as improvements in technology, lower energy consumption, sand more higher efficiency, sand making machine mechanical sand industry irreplaceable good performance characteristics are widely used in a variety of ores, cement, refractories, aluminum where the soil clinker, emery, glass raw materials, mechanism building a variety of industries such as sand and stone and various metallurgical slag crushing and sand making job. Impact crusher in order to play safe and reliable performance, and maintenance of the equipment needed in the day-to-day process of using the equipment to ensure good operation efficiency.Impact crusher (also known as sand making machine) and Crusher due to the long-term work in harsh conditions, exacerbated by the rotor bearing wear. The rotor crusher does not work, the rotor crusher irreplaceable. However, it is also fragile, switched from bearing not only expensive, but replacement is very difficult, often resulting in lost production. How to take effective measures to improve the life of impact crusher rotor bearing, many customers are most concerned about in the course of the problem. We need to its normal situation more attention:
First, they have to improve the accuracy of the rotor balance. Impact crusher rotor quality, high speed, mass deviation caused by after the the rotor casting deviation and mounting plate hammer will unbalanced centrifugal force generated when the rotor rotates.
Second, with the relationship between reasonable regulation. Impact broken rotor bearings withstand impact loads suffered by the size of the load on the rolling body is not the same impact, in that rolling bodies of the load under the joint effect of the maximum force, the inner and outer ring raceway is here the rolling body contact with the largest force.
Third, in the choice of rotor-bearing model to the correct choice. Double row spherical roller bearings have a strong bearing capacity, aligning performance advantages, so this bearings as rotor bearing more choice.
Fourth, it is necessary to improve the the stone crusher bearing force status.
