coal slime dryer

Coal slime dryer belongs to drum dryer or rotary drum drying equipment, which is a very mature drying equipment of mining equipment manufacturers. It is suitable for drying coal slime, sludge, metal and non - metallic minerals, etc. When the internal temperature of coal slime drying machine is not in equilibrium, the drying effect of the slime will not be uniform, and we can control the ventilation of the cylinder through the air brake of the coal slime drying machine.

When the internal ventilation of coal slime dryer is too large, you should timely reduce the brake to ensure that the entire firing is in the positive pressure working environment. Control the inlet amount of the wind at the bottom of the billet stack if it is necessary. After reducing the wind damper of coal slime drying machine, add the fuel with low water content. When the temperature of coal slime drying machine returns to the normal degree, gradually improve the damper, and then add ventilation to accelerate the combustion of fuel and improve the heat in the coal slime drying machine. When the ventilation of coal slime dryer is over an hour, improve the damper height to make the firing zone in front of negative pressure environment and the rear material at positive pressure environment. At the same time, keep the air inlet amount of cooling and insulation positions in order to improve the quality of fuel combustion and heat exchange efficiency, thus it can eliminate the under fire of coal slime drying machine.
