The sliming water closed circuit practice of Chensilou coal process plant;

In order to save water and reduce polluted water discharge,we use elliptical tube in rectangular steel fin tube which is treated in hot dipping zinc and use force cooling by blast axial flow fan to condensate the air in tube then return the condensate to boiler to form a closed circuit,thus replace conventional water cooling tower.

Simplified process of slime water treatment employed at Chengzhuang Coal Preparation Plant in that all slime water was collectively treated;the particulate content in washwater was then reduce down to 10g/L by reasonable flocculent addition;realized were the automatic balance and closed circuitry of wash water.

Scaling mechanism of closed circulation of ash sluicing water in ash sluicing;

Internally it achieves the closed circulation of the gas, water and waste heat and comprehensive reutilization of the solid waste and externally, Qinggang successfully disposed the hazardous waste of chrome slag from the chemical industry.

The adoption reduces slime water concentration, enables the closed circulation and increases product quality.

In order to prolong the maintenance intervals of spindles,starting from the spindle structure,analysis is done to the circulating circuit of oiling system for spindles.
