Motor - speed reducer - gear drive cylinder - cylinder driven ball - ball drip to crush the coal
   Coal mill mainly relies on crushing methods to grinding coal, while the rolling ball in the barrel also has mangle coal and crushed effect.Coal and hot air enter from one end of the hollow journal, hot air drying of coal and coal dust, while a certain particle size of coal from the other end of the hollow journal will be sent out.
    Ball mill grinding of coal output is defined as guaranteed under the conditions of pulverized coal fineness, the grinding of the Coal Mill capacity per hour.The diameter of the Ball Mill  has an impact on unit power consumption of coal and steel ball of metal loss, according to their principle of minimum total cost to select.Generally use 30 to 40 mm diameter steel ball, hard and large size coal use the bigger ball.Meanwhile, the ball size should be appropriate match.
    During operation, the ball will gradually be worn, the diameter decreases, the general ball must be added once a day.
