A multi-layer water sieve screening machine

Abstract

The invention relates to a multi-layer water sieving machine. The multi-layer water sieving machine is characterized by comprising a sieve cylinder, integrated ore supplying / discharging pipes, and multi-layer sieving devices, wherein the lower part of the sieve cylinder is in a circular truncated cone shape, the upper part of the sieve cylinder is in a cylindrical shape, the integrated ore supplying / discharging pipes are concentrically installed in the sieve cylinder in the axial direction, and the multi-layer sieving devices are concentrically installed on the outer parts of the integrated ore supplying / discharging pipes in the sieve cylinder in the axial direction; each layer of sieving device is composed of an upper-part truncated-cone-shaped sieve body and a lower-part inverted-truncated-cone-shaped under-sieve ore collecting device, the lower end of the sieve cylinder is provided with an on-sieve ore discharge pipe, the side face of the lower portion of the sieve cylinder is provided with a water supply pipe, and a vibrating motor is arranged above the integrated ore supplying / discharging pipes. The multi-layer water sieving machine has teh advantages that 1, ore slurry sieving process is conducted in water, the sieving efficiency of a fine sieving device is improved, the circulation volume of middling products is reduced, and over grinding is prevented; 2 the multi-layersieving devices are arranged in space in a stereoscopic mode, the sieving machine thus occupies little area, the cost is reduced, and the economic benefits of a concentrating mill are increased.

Description

technical field [0001] The invention relates to the technical field of ore dressing and screening machinery, in particular to a multi-layer water screening machine. Background technique [0002] As a grading device, the fine screen has been widely used in the mineral processing industry. When working with a fine sieve, the pulp enters the sieve surface, the particles larger than the sieve hole are discharged from the end of the sieve surface on the sieve, and the particles smaller than the sieve hole are discharged from the bottom of the sieve. Since the minerals on the sieve need to be washed and discharged by the pulp, a considerable part of the minerals on the sieve should be sieved through the sieve holes and enter the minerals under the sieve, which remain on the sieve due to failure to effectively sieve , affecting the screening efficiency.
