Gyratory sifter is one kind of high efficiency and large capacity sieving equipment. Users can realize high-output sieving needs of different materials by simply increasing or decreasing the spindle speed and the excitation force of machines. Gyratory sifter adopts a fully enclosed structure, which is easy to install and control. The general design is 3 to 5 layers. Users can install the number of screen layers as required. Under the action of inertial force, the screen box makes reciprocating motion, which drives the screen surface to make periodic shaking, so that the materials on the screen surface and the screen box make a directional jump movement. The material smaller than the mesh will fall into the lower layer, and the material larger than the mesh will jump and discharge from the coarse outlet.. Different capacities and different size models are avaliable. Electrical supply data : 380 V, 50 Hz
