Atomization device for cement grinding aid and using method thereof

Abstract

The invention relates to an atomization device for a cement grinding aid. The atomization device comprises a liquid tank, an air pump, a gas-liquid mixing device and a spray head, wherein the air pump and the liquid tank are connected with the gas-liquid mixing device respectively, and the spray head is arranged on the discharge hole of the gas-liquid mixing device. The invention also relates to a using method for the liquid atomization device. The using method comprises the following steps of: filling the liquid cement grinding aid into the liquid tank, and then arranging the liquid tank on an electromagnetic valve; butting the air outlet of the micro air pump and the air inlet of the gas-liquid mixing device; arranging and connecting a synchronous controller, the electromagnetic valve and the micro air pump, and switching on a power supply; and regulating the electromagnetic valve and the micro air pump, and controlling the atomization granule diameter of the liquid cement grinding aid to be 3.2 to 10 microns. Under the condition that a cement grinder equipment system is not changed, by adopting the cement grinding aid atomization device, the dispersibility and flowability of a material in the grinder can be changed, electrostatic adsorption and ball paste grinding of cement micro granules are effectively eliminated and the cement granule graduation is optimized.

Description

technical field [0001] The invention relates to an atomizing device for cement grinding aids, and also relates to a method for using the liquid atomizing device. Background technique [0002] At present, there are more and more cement companies using cement grinding aids in China. With the increasingly fierce competition in the cement market, the profits of cement companies are getting lower and lower, prompting cement companies to take a series of measures to reduce production costs in order to pursue profits. It is believed that cement grinding aid technology is one of the supporting technologies for cement enterprises to realize energy saving, emission reduction, consumption reduction, and economic benefit improvement. At present, there are mainly two kinds of cement grinding aids in the market: powder and liquid. Abrasive products also have the following problems: 1. Changing the dispersibility and fluidity of materials in the mill is poor, and cannot effectively elimina...

Problems solved by technology

[0002] At present, there are more and more cement companies using cement grinding aids in China. With the increasingly fierce competition in the cement market, the profits of cement companies are getting lower and lower, prompting cement companies to take a series of measures to reduce production costs in order to pursue profits. It is believed that cement grinding aid technology is one of the supporting technologies for cement enterprises to realize energy saving, emission reduction, consumption reduction, and economic benefit improvement. At present, there are mainly two kinds of cement grinding aids in the market: powder and liquid. Abrasive products also have the following problems: 1. Changing the dispersion and fluidity of the materials in the mill can not effectively eliminate the phenomenon of electrostatic adsorption and ball paste grinding of cement fine particles, and optimize the gradation of cement particles

2. The phenomenon of cement clinker is still high, and the increase in the total amount of corresponding mixed materials is limited

3. It is not ideal to reduce the fineness of cement grinding or increase the specific surface area of ​​cement, and the strength of cement at different ages is not high, resulting in a low effective utilization rate of cement grinding aids.
