1. Ball milling and rod grinding process. For beneficiation, using one or two stages of grinding, the ore can be ground to any size, economy and efficiency required for beneficiation. Two or more stages of grinding are usually determined by the requirements for stage selection. And a period of two processes compared with major advantages for some grinding process is: simple equipment, low capital investment, easy to operate, not because of a shutdown of the mill ore block affect the work of another grinding segment, avoid downtime The loss is small, but the mill has a wide range of grain size, reasonable ball loading, and it is difficult to obtain a fine final product. The beneficiation equipment has low efficiency, which requires two sections of grinding. When the final product is required to have a maximum particle size of 0.2 to 0.15 mm, a grinding process is generally employed. For small plants, in order to simplify the process and equipment configuration, a grinding process can also be used when the grinding fineness requires 80%-200 mesh. The outstanding advantage of the two-stage grinding is that it can obtain a finer product, which can be coarsely ground and finely ground in different grinding sections, especially suitable for stage treatment. In large and medium-sized factories, when the grinding fineness is less than 0.15mm (ie 80%-200 mesh), it is economical to use two-stage grinding, and the product has uniform particle size composition and less over-grinding. According to the different connection modes of the first section of the mill and the classifier, the two sections of the grinding process can be divided into three types: the first section is open; the second section is fully closed; the first section is partially closed, and the second section is always closed. Grinding process. 2. Self-grinding and dressing equipment process, self-grinding process has two kinds of dry grinding and wet grinding. Wet grinding is often used in the concentrator. The technician pointed out that in order to solve the problem of difficult-to-grind particles in self-grinding and improve the grinding efficiency, a small amount of steel balls are added to the self-grinding machine , which is called semi-self-grinding. Self-grinding often works in combination with crushing equipment such as fine crushing, ball milling, gravel grinding, etc., and can form a variety of processes according to the coupling method. Crushing is a process in which the bulk material becomes smaller under the action of mechanical force. It is an important part of the mineral processing process and can be divided into four stages: crushing, grinding, superfine pulverization, ultrafine pulverization, and the pulverization process. The basic principle is "more and less grinding."

Introduction to the process flow of grinding ore dressing equipment
Mineral processing equipment: Grinding equipment is the key equipment for crushing ore and then crushing. Grinding process is very important for the selection of equipment. Grinding plays an important role in the beneficiation process. The grinding process includes three processes: ball milling, rod grinding and self-grinding.
