Serially-connected grinding technology and equipment thereof

Abstract

Serially-connected grinding technology and equipment thereof belong to grinding technology and equipment thereof; the equipment comprises a vertical mill, a powder separator, a blower fan, and a ball mill; the powder separator is connected with the upper part of the vertical mill; fine powder collectors are disposed at the periphery of the powder separator; a powder outlet of the powder separator is connected with the ball mil through a powder conveying device; an air outlet of the blower fan is connected with the bottom of the vertical mill; a backwind pipe is connected with the top of the powder separator. The invention adopts the grinding technology combining the vertical mill with the ball mill and the material bed-rolling grinding technology; powder grading is realized inside the equipment; qualified materials are collected in advance, which reduces material underlay and over-grinding phenomena of the ball mill; a traditional mode in which the millstone rotates and the grinding roller is driven for a vertical mill is changed into a mode in which the millstone is fixed and the grinding roller rolls; powder grading is realized inside the equipment; the working efficiency is high; the fine grinding performance is good; the abrasion is less; the energy consumption is low; the investment is saved; and the maintenance is safe and simple.

Description

technical field [0001] The invention relates to a grinding process and its equipment, in particular to a series grinding process and its equipment. Background technique [0002] Since my country's reform and opening up, the national economy has grown rapidly, "scientific and technological innovation, independent innovation" has become the mainstream of today's industrial development, and my country's industry is gradually developing in the direction of intensive, energy-saving, emission-reducing, and low-carbon. my country is a big cement producing country and also a big cement consuming country. It is of great significance for our country to save energy and reduce emissions by vigorously reducing the excessive energy consumption in the process of cement grinding. According to relevant statistics, my country's cement plants need to grind more than 30 kinds of materials to produce 1 ton of cement, and the power consumption of grinding accounts for about 65% to 70% of the tota...

Problems solved by technology

However, the particle shape of the material discharged from the roller press is not good, which affects the operability of the concrete. Therefore, all the materials discharged from the roller press must be put into the mill for grinding. The re-grinding of the material that has reached the final product requirements not only affects the output of the mill. , it is also easy to cause over-grinding, which affects the strength of clinker

For more than 100 years, people have done a lot of research on the production process and mechanical dynamics of mills. Although some progress and achievements have been made, there are still technical problems that have not been overcome in practical applications.
