Centrifuge as an efficient solid - liquid separation equipment, widely used in chemical fertilizer plants, lysine factories, sugar mills and other industrial enterprises. As the centrifuge drum is a large diameter (about 1 m) and high speed (hundreds to thousands per minute, rpm) of the rotary shell, so when its running under the effect of centrifugal force generated within the wall of a large drum stress, stress one of these high-speed rotation from the drum wall when the quality of metal produced by the centrifugal force of its own; second, because attached to the drum wall on the screen, the material and liquid layers are generated by the centrifuge force acting on the drum wall , thus leading to the drum wall and a corresponding stress.

 On the other hand, large diameter, high-speed rotation of the rotary shell easily cause shock, if the equipment manufacturing and installation of precision is not high enough, or improper operation is running, the shock is more serious. Stress and vibration are two reasons for the centrifuge housing or the spindle will cause material fatigue fracture, leading to an accident or mechanical safety incidents. In recent years, our region's chemical plants and sugar have occurred in the centrifuge screen basket fatigue fracture, debris flying machine, almost causing an instance of personal injury accidents.

 Therefore, to safety, it is necessary to centrifuge drum (sieve basket) of the force, selection, security checks and other security-related issues were discussed.

 Centrifuged in honey, the material (grain, liquid) in the drum to make a circular motion around the central axis, the role of the centrifugal force of this material that centrifuges spin the drum to withstand more than 1400 tons of centrifugal force, when coupled with the drum the weight of their steel and sieve generated by centrifugal force, centrifugal force will greatly exceed this number. This great variety of centrifuge force in the process to complete the task, but also any mechanical damage, personal security incidents. Therefore, we must attach great importance to the production of centrifuge safety issues to prevent this accident.
