[0002] In the cement production process, cement grinders are usually required to crush and grind cement raw materials. After a period of use, the grinding bodies in the cement grinders will gradually become smaller due to wear. Therefore, in order to increase the subsequent output and grinding efficiency of the cement grinder, it is necessary to check the filling rate of the cement grinder and overhaul the cement grinder. If the grinding bodies are out of stock or the cement grinder needs to be overhauled, the grinding bodies need to be re-screened and reloaded. However, the existing screening method can only screen the ground cement raw materials and grinding bodies, and cannot screen grinding bodies of different sizes, which in turn affects the filling and overhaul efficiency of the grinding bodies of the cement grinder. Therefore, it is particularly important to study a device for screening grinding bodies. Utility Model Content
