Description

Technical Field

[0001] This invention relates to the field of mineral screening technology, specifically to a mineral screening equipment and screening method. Background Technology

[0002] Crushing and screening equipment is a type of mechanical equipment that can crush mined rocks and screen them according to certain specifications. In order to meet the needs of various basic construction projects for crushed stone, crushing and screening equipment has become an indispensable construction equipment.

[0003] Patent application number 201910803263.9 discloses a grading and screening device for mine stone materials; it includes a cone-shaped platform, with multiple annular rings of progressively increasing diameter inserted into the top of the cone-shaped platform. An operating rod is fixed to the bottom of each annular ring, with the bottom end of the operating rod positioned at the bottom of the cone-shaped platform. Each of the annular rings has a channel, with the channel length on the inner annular ring being greater than that on the outer annular ring. This invention, by setting up annular rings and an arc-shaped plate, allows the arc-shaped plate, under the action of a motor, to push larger stones blocked in the channels, enabling stones of suitable diameter to pass through the channels and enter the appropriate annular rings. This brings the stones between adjacent annular rings closer together, causing the annular rings to move upwards and separate from the cone-shaped platform. This allows materials with progressively increasing diameters to be released sequentially from the cone-shaped platform. The overall height is low, allowing for use in mine tunnels with limited height, improving the versatility of the application environment, and reducing noise pollution.

[0004] The grading and screening equipment for this mine's stone materials lacks a dust collection device, resulting in a large amount of smoke being generated during the screening process. Users nearby are easily exposed to the smoke, which can cause health problems over time. Therefore, it is necessary to design a more practical mine stone material screening equipment that can prevent dust leakage. Summary of the Invention
