By loading the suitable diameter steel bar to break the material, it can meet the requirement of a section of coarse grinding, and it is the best substitute for the traditional manganese steel liner. The rubber liner used for the rod mill can only be used in the cylinder part and the end part should also be made of steel liner. Our products are excellent wear resistance, compared with manganese steel liner: weight easy installation, low energy consumption, high wear resistance, long service life, low noise, is the damp mill of high quality accessories, has been widely used in mining, metallurgy, iron and steel, nonferrous metals, phosphorus compound fertilizer, coal water slurry, flue gas desulfurization, building materials mills, etc..
The structure and working principle of the rod mill:
This product is made up of the working parts, such as the feeding part, the cylinder body part, the discharging part, and the bearing, transmission and basic parts. The cylinder mill equipped with steel rods, with the centrifugal force of the rotating cylinder produces, will enhance the grinding media to a certain height after falling down the ore crushing, grinding and grinding medium and the cylinder lining plate between the ore grinding ore and slag, this process is called grinding process.
The difference between the rod mill and the ball mill:
Rod mill and ball mill for grinding ore as such, should be selected according to the use of ball or rod mill, different working conditions in general, suitable for coarse grinding and fine grinding for rod mill, ball mill, the reason lies in the grinding medium rod mill for steel rod, line contact, and the grinding medium, milling machine for steel ball point contact, contact way are determined by different grinding granularity.
The rod mill currently used less, mainly used in coal chemical coal water slurry preparation, quartz sand, silica sand, sand filling, tungsten ore, bauxite, feldspar etc.. The ball mill is well known for its extensive use. But rod mill is a trend. Now, more and more rod mills are used internationally, which may be related to the change of grinding technology. More and more people accept the concept of multiple crushing and less grinding.
Three main uses of rod mill:
1, the reelection or magnetic separation plant of tungsten tin ore and other rare metal mines often use rod mill steel bars in order to prevent the harm caused by smashing.
2, when the two stage grinding process is used, if the first stage is worn from 20~6 mm to 3~1 mm, the rod mill steel bar will be used for the first time. Therefore, when making the grinding equipment, the production capacity is larger and the efficiency is higher. Because the weight of the same weight ratio rod ball bearing surface area second section of fine grinding, grinding rod milling is lower than the productivity and efficiency;
3. In some cases, it can replace the short head conical miner for fine crushing. When dealing with soft or hard ore (especially the ore with large viscosity), rod mill steel bar will be 19 - 25 mm (or 32 mm) of ore grinding to 6 - 10 orders, compared with short head cone crusher and the screen in the closed configuration is simple, the cost is also is low, and it can make the workshop dust broken open reduction. The coal grinder / coal mill steel bar is widely used in cement, silicate products, new building materials, refractory materials, chemical fertilizers, black and non-ferrous metal beneficiation and glass ceramics production industry. Dry or wet grinding of all kinds of ores and other grindable materials is carried out.
