Roller-slitting grinding mill feeding and discharging assembly

Abstract

The invention discloses a feeding and unloading assembly of a roller cutting grinder, which comprises a belt, a pulley, a feeding slot fixedly connected with the belt, a first material bin, a grinding bin, a decompression chamber, an air outlet pipe and an air inlet tube; the grinding bin includes a feed pipe, a second bin, a discharge pipe and a U-shaped ring groove. The second bin is a cylindrical structure with a regular polygon on the bottom and top. On each rectangular side of the second silo near the bottom surface of the second silo, the lower opening of the outlet of the second silo is at the same height as the bottom surface of the second silo; The bottom surface of the silo is used as a cone on the bottom surface, and the height of the cone is lower than that of the second silo. The invention can automatically send the material into the grinding bin through the belt transmission system, realizes the automatic feeding of the material, can avoid the situation of material accumulation in the second bin due to the untimely slide of the material, and does not need manual cleaning of the material, saving Manpower, improve production efficiency.

Description

technical field [0001] The invention relates to the technical field of ultrafine crushing and preparation of non-metallic minerals, in particular to a feeding and unloading assembly of a roller cutting grinder. Background technique [0002] In industrial and agricultural production, it is often necessary to use a mill to crush various materials. According to the different grinding media and grinding materials, the mill can be divided into: ball mill, column mill, rod mill, tube mill, autogenous mill, rotary mortar roller mill, vertical mill, multi-layer vertical mill, vertical Type roller mill, DMC mill, etc. Batch ball mills are generally used in the production of the ceramic industry, and the wet method is used for production. The grinding action can be divided into two parts, one is the grinding action between the grinding bodies and between the grinding body and the simplified body, and the other is the impact when the grinding body falls. In order to improve the grind...

AI Technical Summary

Problems solved by technology

Most of the materials in the traditional grinder cannot be automatically fed and discharged, which is easy to cause the materials to accumulate in the feeding pipe, and after the feeding is stopped, all the materials in the silo cannot enter the cylinder for grinding, which requires manual labor. Cleaning up is inefficient and wastes human resources

[0005] In the feeding device of the roller mill in the prior art, the operator must manually tidy up the feeding material placed on the material table when feeding the material. Under the action of the feed material is sent into the roller mill

Such manual finishing increases the workload of the operator, and the feed cannot be rolled on the material table, so the efficiency is very low
