After deep processing, tin ore is widely used not only in metallurgy and metal materials, but also as an important functional material in national defense and high-tech applications. For tin ore extraction and processing, generally, beneficiation is used, and the indispensable grinding equipment in the tin ore beneficiation production line is the tin ore rod mill.
The rod mill for tin ore is a kind of grinding equipment developed for the characteristics of tin ore. The grinding medium is a steel rod, and the wet rod mill equipment is commonly used in tungsten ore beneficiation plants. Choose CIC rod mill manufacturer with custom selections of rod mill machines.
Before the tin ore is selected in beneficiation operations, a rod mill is generally used to ensure that the ore does not undergo excessive crushing. This is mainly because tin ore is fragile and prone to wear, and grinding with a ball mill often leads to over-wearing.
In the two-stage grinding operation, if the particle size of the ore is reduced from 20-6mm to 3-1mm in the first stage, a tin ore rod mill with high production capacity and efficiency can be selected for the second stage grinding. Since the surface area of a certain weight of rod charge is much smaller than that of a certain weight of ball charge, the production rate and efficiency of the rod mill are lower than those of the ball mill in the second grinding stage.
If relatively soft or less hard impurities exist in the tin ore, a tin ore rod mill can be used to grind ore particles of 19-25mm to 6-10 mesh. In this case, the use of a tin ore rod mill instead of a cone crusher reduces the beneficiation costs and dust pollution in the crushing workshop, while ensuring the grinding conditions.
It mainly consists of an electric motor, main reducer, transmission parts, cylinder body parts, main bearings, slow-speed transmission parts, feed parts, discharge parts, annular seals, thin oil lubrication station, spray lubrication of large and small gears, basic parts, etc. The main reducer is a parallel-axis, hard-toothed surface device.
The small curvature of the conical end cover of the tin ore rod mill allows the steel rods to move regularly inside the mill;
The large diameter of the hollow shaft in the tailings discharge facilitates inspection and repairs, while also quickly discharging tailings by lowering the slurry level;
The tin ore rod mill generally accepts ore with a particle size range of 20-30mm and produces particles with a size of 0-3mm. Its production capacity is larger than that of the same specification ball mill, which improves the yield of the output, allowing the beneficiation work to be completed efficiently within the specified time;
The tin ore rod mill crushes materials by the full length of the steel rod, resulting in uniform force and particle size and less over-crushing;
In the tin ore re-selection system, the tin ore rod mill grinds the ore using the full length of the rod, resulting in a small curvature of the conical end cover, allowing the steel rod to move regularly inside the mill, making its force more uniform. In the coarse grinding stage, the fine particles are less susceptible to being crushed before the coarse particles are fully ground, effectively preventing over-crushing of the ore and resulting in uniform product particle size and high-quality discharge.
