The Application And Effect Of Binders Used In Coal Briquettes Production Line
Mar 12, 2017

The application and effect of binders used in coal briquettes production line


In the whole industry, in addition to the desulfurization gypsum briquette press, press the 

briquettes does not need to add any adhesive, forming, and the briquettes rate of more than 95% . 

Like other materials: mineral powder, coal, clay, iron, aluminum, iron, coke, iron oxide, carbon 

powder, carbon powder, slag, gypsum, tailings, sludge, kaolin, activated carbon, coke powder and 

other powder, waste, and so on, there is a need to add most of binder. Below I will introduce 

briquette press machine which use adhesive and its effect. 

(adhesive to briquette press machine used for quasi introduction)

final coal briquettes

The adhesive is an important part of briquette made not a ready-made panacea, is not immutable and 

frozen, changes with the composition of coal and adjust and improve the matching technology. To 

grasp several principles:


1,Stability and composition of coal in coal:

2,Standard for quality of adhesive components and materials (content, moisture, fineness);

3,Binder ratio, fluidity and permeability of binder;

4,The influence of the preparation process, stirring mode, stirring time and stirring temperature 

on the molecular chain of the adhesive.

5,The relationship between the proportion of binder and the proportion of adding method and raw 

water.

Bentonite reasonable use (three two aluminum oxide, silicon dioxide).

1, according to the characteristics of coal gas indexes, at present generally used humate adhesive.

1) the humic acid binder has a strong affinity to the pulverized coal through physical and chemical 

reaction.

2) high surface activity, inclusion, permeability strong.

3) reaction activity, improving the coal in the furnace combustion reaction, gas composition, gas 

generation and consumption. To improve the combustion process of coal in the gasification reaction 

rate and gas conversion efficiency.


2, composition and proportion of raw coal: as the content, moisture, ash melting point, volatile 

and physicochemical indexes, is generally a liquid binder and powder additive 1:10:50.


However, 10 of the ratio is the content of lignite humic acid, rather than the number of lignite.

3, preparation process:

1)lignite humic acid content general requirements 40-50%.

2)into 100--120 to improve the fineness, wetting force, expansion force, seepage force.

3)after the water into the reactor, heated to 40 degrees, adding sodium hydroxide, stir well, 

continue to heat up to 90 degrees, add humic acid, stirring for 1.5 - 2 hours, the temperature is 

not more than 95 degrees.

4)add ratio: about 5%.

5)add: metering valve and spiral powder quantitative feeder, accurate measurement.
