Cement ball mill is widely used in cement, silicate products, new building materials, refractories, fertilizers, black and non-ferrous metal beneficiation, and glass-ceramic industries, and dry or wet grinding of various ores and other abrasive materials. equipment.

In accordance with the cement ball mill motor, motor speed reducer, reducer cement ball mill in order to test run. China's cement machinery and equipment installation and construction acceptance of the provisional technical specification "Building Regulations 7-62" provides that the motor runs for 4 hours, with a reducer running 8 hours, with a cement ball mill running 24 hours. Cement ball mill spindle and drive bush temperature does not exceed 55 °C, reducer roller bearing temperature does not exceed 70 °C, it is considered qualified. Now there is no clear provision in foreign countries. The cement ball mill is running. After two or three hours of operation, the temperature rise and vibration are kept within the specified limits.

When the speed of the energy-saving cement ball mill barrel is very low, the steel ball coal cannot be taken up, only rolling in the lower part, and the energy-saving cement ball mill has a small output; but if the energy-saving cement ball mill rotates at a high speed, it acts on the steel ball and the coal block. The centrifugal force is greater than its gravity, the steel ball and the coal will rotate together with the barrel, which means that the coal grinding effect will be lost. The minimum speed at which these conditions occur is called the critical speed. The best rotational speed of the energy-saving cement ball mill shall be such that the steel ball in the cylinder body has the maximum lifting height. At this time, the steel ball has the greatest impact force and the coal grinding effect is the best.
