Let's talk about the grinding media of the mill, mainly about the rod media of the rod mill. The energy carrier that pulverizes the material by its own impact force in the rod mill. The most commonly used grinding media are spherical media and rod media. In some cases, irregular shapes such as round tables, cylindrical balls, and short round bars are used. This is called a shaped medium. Material for the grinding media multiple special processing or cast iron alloy, followed by a ceramic, aluminum oxide and the like; gravel pebble mill grinding media used in nearly spherical, spheroid, egg-like, specifically preparation from the rock or ore of. The grinding medium of metal material should be resistant to abrasion and corrosion, have sufficient strength and hardness, be not easily broken during work, and retain the original shape after being worn. The amount of water pump for the metal ball medium (the amount of the medium pumped by the 1t material, kg/t) and the ball breaking rate (the ball of different sizes under the external force, the amount of the rupture accounted for the test ball, %) is the mass The main indicator. For rod media, it is not easy to bend and break. In grinding production, the function of grinding media as much as possible is the most important factor to improve the efficiency of the mill. To this end, it is required to (1) determine the large size according to the nature of the material to be ground, the feedstock and the particle size of the product, and the process requirements of the next step. The shape and material of the medium are not solved; (2) According to the requirements of the feeding material and the particle size distribution of the product, the appropriate ratio of the medium size to the different size is determined; (3) the medium filling is determined according to the mill type and the mill rotation rate. Rate; (4) According to the wear law of the medium and the production conditions, determine the reasonable replenishment of the unconcealed medium. The above simple description of the rod media of the rod mill is described below. Changxing Mingwang Rubber & Plastic Technologies Co.,Ltd. , https://www.cxmingwang.com
