The crushing equipment must be equipped with the self - protection system in order to run safely at low fault level . and the overload protection system will play an important role in modern crushing equipments 这就要求设备本身应具有良好的自我保护系统,以使设备安全运转,故障率保持在低的水平上。因此,过载保护系统在破碎设备中占有着极为重要的地位。
It indicates from engineering applications that the working conditions of crushing equipments are extremely inclement because the load fluctuates considerably . the dangerous circumstance of overloading occurs abruptly when uneven charging or hard materials are loadrfinto the crushing equipment 破碎设备作业工况极为恶劣,工作负荷波动性很大。常因入料不均或因破碎腔进入硬度极强的不可破碎物而出现突然的大幅度的超载险情。
To rationally configurate the crushing equipment so as to form various crushing flowsheets and achieve a high production efficiency and economical results is described and the crushing flowsheets that are suitable for small concentrators under the existing home - made equipment conditions are discussed 论述了对碎矿设备进行合理配置组成不同的碎矿流程,以取得较好的生产效率和经济效益,探求了在国产现有设备条件下适合小型选厂的破碎流程。
