Ball Grinding Mill


The ball mill is a key equipment for grinding materials, widely used in powder-making production line such as cement, silicate sand, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc. Ball mill can grind various ores and materials with dry type or wet type. There are two kinds of ball mills, grate type and overfall type due to different ways of discharging material.

Ball Grinding Mill Debugging

  • If the operating height from the pressure springs (the efficient height following the spring is compressed) is lower, the pressure that the grinding roller exerts on the materials is larger and the output is larger. Nonetheless, based on the loading condition from the primary motor and whilst the grinding roller is worn smaller sized, the spring is compressed gradually. The working height in the pressure spring shall be a lot more controlled inside the range of 145-160mm.
  • No-loading trial operation. Before the trial operation, the grinding rollers shall be encircled and fixed by steel wires to avoid the contacting and bumping in between the rollers and grinding rings. The no-loading trial operation from the principal frame need to final not much less than a single hour. The main frame shall run smoothly and stably.
  • The temperature from the oil in the tank shall not be over 80 C, and its temperature rise shall not exceed 40 C. as for the rotation direction of the main frame and classifier,, the blower shall be turned on without load. You’ll be able to load until the blower runs usually. Then observe whether or not it runs smoothly steadily with out abnormal noises and vibration. The highest temperature of its rolling bearings shall not be more than 70C, and its temperature rise shall not surpass 35C.
  • The trial operation without load shall final not much less than eight hours. Following the regular operation, the entire machine shall be without having abnormal noises and air leakage in pipe connections. Then fix tightly all the fastening components once more before the grinding mill is place into typical operation.
