Can You Find the Reasons of Unstable Molding of Crushing Machine

A suitable amount of water can lubricate the machine mobile crusher plant, reduce friction in the molding system and improve coal briquette's mechanical strength. But too much water will thicken the particle surface, influence the compression between particles and in turn reduce the coal briquette's mechanical strength. Besides, too high moisture content will cause crack in the coal briquette and result in breaking down.

The adoption of hydrophilic binder is helpful to mold the coal briquette. Taking a reasonable amount of water (often 10%-15%) to wet the particle surface helps particles bond to each other. Too much water will lead to the opposite result. If we adopt the hydrophobic binder, water will decrease its binding effect. Under this situation, we should control the moisture content below 4%. In one sentence, the moisture content should be controlled flexibly within a reasonable range according to the actual situation.

Grain Size and Grain Composition Should Be Designed According to the Following Principles: Ensure that the particles are arranged closely within the coal briquette to improve the products' mechanical strength. It has been proved by experiment that smaller particles are easier to be closely combined. When adopting the binder molding process, the best grain composition should be minimized in total superficial area and total gap between the particles in order to reduce binder consumption and production cost of coal briquette.
