Use a certain volume of slurry bottles (usually 1L) to fill the slurry samples and weigh them. The weight of the slurry plus bottle is q1, and the slurry is poured into a sieve immersed in a water basin (using a 200 mesh or 100 mesh standard sieve) for wet screening, and sprayed with a fine water stream until the washed water is clear, and then Move the product on the sieve back to the bottle and add water to the same mark as the original slurry. Reweighing, obtaining the product on the sieve and the weight of the water is q, the known bottle weight is a, the volume of the bottle is b (ml), and the fraction yield of the product on the sieve (+200 mesh or +100 mesh) Is: x = (qab) / (q1-ab) * 100%. In the grinding process of the ball mill, in order to achieve sufficient monomer separation in the useful minerals in the ore, in order to create favorable conditions for the sorting operation, after the test analysis, the grinding fineness is determined and expressed as a percentage of the -200 mesh content. . It should be noted that this test method assumes that the density of the product on the screen and the product under the sieve are equal, and if the difference in density is large, the result of this detection method is an approximation. Some class take a beneficiation plant integrated fineness like, after drying in the processing chamber separated 100g, and then measure the fineness were wet-sieved. On the other hand, in terms of reducing the breaking rate of the grinding balls and the lining plates in use, the impact stress of the grinding balls is the key to the selection of the grinding balls and the lining plates. Because the ball mill processing capacity and product particle size have a significant impact on the efficiency of subsequent operations and the technical indicators of the overall production process, the research on ball mills has been widely concerned and highly valued at home and abroad. Every year, in order to ensure the maintenance cost of its normal operation, the company accounts for a large proportion of the operating costs of the enterprise. In order to solve the practical problems in the working process of the ball mill, it is necessary to have a comprehensive understanding of the working condition of the ball mill, and the analysis made by this is scientific and effective.

Rapid screening method can improve the precision measurement of grinding equipment
Whether the grinding fineness of the grinding equipment is reasonable requires a certain measurement method, so we also carefully select the fineness measurement method of the grinding machine , which is directly related to the production quality of the equipment. At present, the common measurement method of the mill equipment is the rapid sieve analysis method, and the application of the process is generally sampled and sieved in the overflow of the classifier .
