The appliance unit operator ought to be answerable for the gear and production index within the ball mill unit operation. To ensure the ore grinding process for the rails, the operator should check, maintain, and adjust the ball mill, its subsidiary facilities, working index, additionally, the output quality. The principle valuables in inspection and maintenance are:

1. Inspection about the equipment and subsidiary facilities. (1) The ball mill inspection: a. Look at the loose screws, the loose, broken screws for the lining plate specifically, which could bring on leakage; b. Look into the wear pattern within the sand return spoon head; c. Pay attention to the coarse running and ball vomiting on the ball mill discharge. (2) The oil feeding system inspection: a. Examine the oil pressure constantly to have it inside collection of 1.5~20kg/cm2;

b. Check the oil mass and temperature, along with the temperature should really be fewer than 30 degree centigrade; c. Examine the king journal oil flow distribution in the ball millto have them well-distributed; d. Look into the viscosity and cleanness with the oil. (3) The motor and electrical appliance inspection: Mainly look into the motor temperature and then make the temperature rise in the allowable value. (4) The classifier equipment inspection: a. Read the blades in the spiral classifier to make certain all is on and the rolling is stable; b. Check perhaps the whirlcone feeding pressure of ball mill is stable, and there are leakage or clogging.mineral sand washer:http://www.hxjq-mill.com/products/sand_washer.html

2. Grinding load inspection. The ore grinding load provides the original feed quantity along with the sand return quantity. To be sure the constant, stable from the ore grinding load of ball mill is the important factor to achieve fine ore grinding effect. a. Maintain ore feed quantity constant and stable and view the ore feed quantity regularly; b. See the change of ore feeding granularity continually, adjust over time and strive to maintain the material in feed bin over in discharge bin; c. Watch the specific situation of sand return and moisturizing, to help keep balance one of several original feed ore, sand return, and overflow; d. Spot the change of motor, electric current, as well as ball mill sound to be able to judge the ball mill load situation by that and clear away the “bulging” in initial phase.

3. The ore grinding graded product quality control inspection. The ore grinding product quality of ball mill mainly means the quality score and fineness of the grading overflow who has direct affect the follow-up separation process and would have to be measured, observed, test, and adjusted frequently.

In a word, the operator of ball mill unit move about, check, test, adjust, observe frequently, and see the change of sound to be sure the ball mill unit consistantly improves best working condition to ensure that a wonderful ore grinding result can be achieved.
