The Raymond mill is one of the most common tools in crushing and sand building production line, although its motor is normally damaged; machine professionals holds view that there are plenty of causes bring about the damage of compound crusher motor; in addition to typical failure cause of popular motor electrical power gear, the running fault of compound crusher also can injury the motor, proven as follows: The dependability and sensitivity with the automated pressure switch; the commences and stops of compound crusher are ordinarily managed through the automated strain switch (pressure relay) straight driving alternating latest contactor.
Because of the Raymond mill performs in harsh situations in long run, the wear of rotor bearing is exacerbated. The rotor is irreplaceable for crusher so that crusher can not operate without the need of it. Nonetheless, additionally it is fragile; the bearing rotor is not really only high-priced, but in addition replaced difficultly, generally resulting in the cut-off loss. The way to get productive measures to enhance the rotor bearing daily life is an important matter that our clients concern about, asking us spend additional consideration: Initial, make accurate choice of rotor-bearing model. Double row radial spherical roller bearing with powerful bearing capability and aligning effectiveness, it's worthy staying picked. Moreover, the rotor and that is with layout daily life of 5000 ~ 10000h is suitable. 2nd, boost the force standing of crusher bearing. The impact load working within the bearing will depend on the impulse acting over the rotor and the support flexibility of bearing. Expanding bearing help versatility will minimize the impact load operating to the bearings. To this end, we could include rubber sheet with proper thickness among the bearing and also the assistance frame to enhance the bearing support flexibility and also to attain the purpose of extending the support lifestyle. The automatic pressure switch largely adopts mechanical structure, which act on speak to by the compress and release of spring. The congenital deficiencies or improper adjustment of automated pressure switch can cause motor injury. The electrical control (particularly for low-power style) is comparatively straightforward, they're frequently get the job done independently by stand-alone group and lying in un-professional operation occasions with torpid repair and maintance, which reasonably enhance in repeat expansion rate of failure.
