Description

Technical Field

[0001] The utility model belongs to the technical field of mine hammer crushing, and particularly relates to a screen plate for mine hammer crushing. Background Art

[0002] A mining hammer crusher, also known as a hammer crusher or hammer mill, is a type of crushing equipment that achieves a "one-shot" stone processing effect. This equipment can directly crush materials with a maximum particle size of 600-1800 mm to 25 mm or less, with a high efficiency of up to 3,000 tons per hour per unit. Unlike conventional stone processing equipment, a hammer crusher can crush materials in a single operation, eliminating the need for multiple crushing steps, thereby improving production efficiency and reducing costs. Furthermore, hammer crushers offer advantages such as high single-unit output, high crushing efficiency, and low operating costs, making them widely used in industries such as mining, construction, water conservancy, and the chemical industry.

[0003] At present, the existing mining hammer crushing equipment needs to replace the corresponding screen plate according to the different particle sizes of the required materials when in use. However, it is relatively troublesome to replace the screen plate of the currently used mining hammer crushing equipment, which not only increases the labor intensity of the operators, but also greatly reduces the production efficiency. For this reason, we propose a screen plate for mining hammer crushing. Utility Model Content
