The Use and Function of Coal Briquette Adhesive

In the coal briquette machine in the industry, in addition to desulfurization gypsum pressure ball machine, briquettes press does not need to add any adhesive, a molding, and into the ball rate of 95 percent or more. Like other materials: mineral powder, briquette, pulverized coal, iron powder, coking coal, aluminum powder, iron filings, iron oxide skin, toner, carbon powder, slag, gypsum, tailings, sludge, kaolin, activated carbon Such as a variety of powder, powder, waste, waste, and so on, there is a large part of the need to add the adhesive, the following I will introduce the coal briquetting machine which the use of adhesive and its role. (Based on the use of binder for briquette pressure ball machine).

Adhesive is an important part of the production of briquette, there is no panacea, not immutable, with the composition of raw coal changes and improve the ratio of the process. To correctly grasp the several principles:

Coal stability and coal quality components;

Adhesive composition and material quality standards (content, moisture, fineness);

The binder ratio, the flowability of the adhesive, and the permeability;

The preparation process of binder, the stirring method, the stirring time and the stirring process temperature on the molecular chain of the binder;

Adhesion Ratio of Addition and Addition to Raw Coal Moisture;

A reasonable and efficient use of bentonite (aluminum oxide, silica).

1, according to the characteristics of gas-fired briquette, the current widely used humic acid nano-type adhesive;

1) humic acid binder on the coal through the physical and chemical reaction has a strong affinity.

2) high surface activity, inclusive, strong permeability.

3) good reactivity, improve the combustion of coal in the furnace reaction, gas composition, gas volume, consumption. Improve the reaction rate and gas conversion efficiency of briquette during combustion and vaporization.

2, the proportion of ingredients and ratio: depending on the raw coal carbon content, moisture, ash melting point, volatile physical and chemical indicators may be, generally liquid adhesive and dry powder additive composition 1:10:50.

But the ratio of 10 is to take lignite humic acid content, rather than the number of lignite.

3, the system with the process:

1) Lignite humic acid content generally requires 40-50%.

2) ground into 100 - 120 purpose fineness, improve the wetting force, expansion force, penetration.

3) the water added to the reactor, the temperature to 40 degrees, adding sodium hydroxide, stir well, continue to heat to 90 degrees, adding humic acid, stirring 1.5-2 hours, the temperature does not exceed 95 degrees.

4, add the proportion: generally about 5%.

5, add way: metering valve and dry powder screw quantitative feeder, accurate measurement.

ZHENGZHOU DAYANG BRIQUETTE MACHINERY CO., LTD, who is professional at coal/charcoal/mineral powder briquette press machine and coal/charcoal/mineral briquettes plant designing and manufacturer more than 20 years, service for hunderds of briquettes machine and briquettes plants customers from domestic and abroad! After thousands of redesigning & updating and hundreds of customers test, we are glad to recommend our key technology connect rollers for press machine and chain plate dryer. Connection rollers for briquette press is greatly short the time to change the rollers and save much cost on rollers; New Designing Chain Plate Dryer is famous for its large production capacity upto 25-30tph, less briquettes damage, and strong drying ability final briquettes moisture content less than 5%!
