Limestone dry grinding powder manufacturing process system

Abstract

The invention discloses a limestone dry grinding powder manufacturing process system. The limestone dry grinding powder manufacturing process system comprises a feeding machine, a dry type vertical grinding machine, a cloth bag dust collector, a main draught fan, a pneumatic conveying device and a limestone finished product powder warehouse; the feeding machine is connected with the dry type vertical grinding machine; the dry type vertical grinding machine is connected with the cloth bag dust collector; the cloth bag dust collector is connected with the limestone finished product powder warehouse through the pneumatic conveying device; the cloth bag dust collector is connected with the main draught fan; and the main draught fan then is connected with the dry type vertical grinding machine. The vertical grinding machine is adopted as a grinding device of the limestone dry grinding powder manufacturing process system, and the grinding capacity is high; and meanwhile, the whole system is relatively closed, and the environmental pollution is small.

Description

technical field [0001] The invention relates to a limestone dry grinding process system. Background technique [0002] The desulfurization absorbent of limestone-gypsum wet flue gas desulfurization system in power plants is generally prepared by purchasing limestone blocks and setting up a grinding system in the factory. , 90% pass). [0003] Because the traditional dry grinding system uses grinding equipment such as rod mills, there is a problem of large dust pollution, while power plants usually use wet ball mill pulping technology, but according to the operating experience of the project, the wet grinding system also has the following defects: The particle size of the material is strictly required to be less than 20mm; the wet ball mill needs to add water, and the grinding capacity is insufficient. Contents of the invention [0004] The object of the present invention is to overcome the deficiencies of the prior art and provide a limestone dry grinding process system ...
