At present, China will need to grinding material there are billions of tons of. At present, resources become depleted, high quality, easy to wear, easy processing source gradually dried up, leaving a large low-grade mineral resources mineral resources at home and abroad increasingly depleted, high quality, easy to wear, easy processing source has dried up. The use of ball mill processing of solid materials greatly increased demand. Low grade mineral resources. The use of ball mill treatment increased the need for solid material.
Country according to the ball mill motors, motors associated reducer, reducer associated mill order to make a trial run. Of cement plant machinery and equipment to install the provisional technical regulations for construction and acceptance of the Building Regulations 7-62 under the motor air operation to four hours, with a reducer to operate 8 hours, with the mill running 24 hours. The mill spindle and the drive shaft tile temperature does not exceed 55 ℃, reducer rolling bearing temperature does not exceed 70 ° C, is considered qualified. Now abroad, not clearly defined, the ball mill operation time, the general operation of two or three hours later, temperature, and vibration is kept within prescribed limits, the ball mill will be found eligible.
Ball mill workers how the correct operation of the mill which is the most important issues in the beneficiation process. The grinding equipment operation is the actual production experience and technology, many ball mill engineering and technical personnel is not very clear, and technical experience in this regard can not be found in various books. Another mining development now hotter, skilled workers are relatively scarce, many without long-term formal training on the job, potentially causing large economic losses to the mining enterprise. To this end, according to many years in the production of debugging on the basis of guiding experience and theoretical technology, the mill has been detailed brief.
