Abstract

The invention discloses a coal mine crushing and screening device, which comprises a tank body, and a feeding hopper is arranged on the left side of the tank body; The upper crushing disc is connected, the outer periphery of the crushing disc is provided with rotating teeth, and the inner wall of the tank is provided with fixed teeth adapted to the rotating teeth; the lower end of the crushing disc is provided with a coarse filter, and the coarse filter is below A guide hopper is provided, and the guide hopper is funnel-shaped and its lower end is provided with a material guide port; two adapted crushing rollers are arranged below the guide hopper, and the material guide port is facing the contact of the two crushing rollers ; A fine filter screen is arranged below the pulverizing roller. The new structure is reasonable in design and easy to use. It is screened twice by the pulverizer twice, which greatly improves the crushing quality, ensures the quality of coal mines discharged from the discharge port, and improves work efficiency; avoids dust from escaping from the feeding hopper, Ensure the surrounding working environment.

Description

technical field [0001] The invention relates to the field of coal mine machinery, in particular to a coal mine crushing and screening device. Background technique [0002] Coal is the most important solid fuel and a kind of combustible organic rock. It is a lush plant growing in a certain geological age. In a suitable geological environment, it gradually accumulates into a thick layer and is buried in the bottom of the water or in the sand. It was formed through natural coalification over a long geological period. Among the various geological periods in the world, the Carboniferous, Permian, Jurassic and Tertiary strata produced the most coal, which is an important coal-forming age. [0003] At present, coal mines need to be crushed in the process of processing. The existing coal mine crushing equipment has high crushing efficiency, but its crushing quality is poor, which reduces the quality of coal mine crushing, which will affect the use effect of coal mines.
