There are roughly three uses for rod grinding:
1) tungsten, tin ore and other rare metal ore reselection or magnetic separation plant, in order to prevent excessive crushing hazards caused, often using rod mill;
2) When using the two-stage grinding process, if the first stage of the energy-saving ball mill is from 20 to 6 mm to 3 to 1 mm, the rod grinding is used for the first stage of grinding equipment , the production capacity is larger and the efficiency is higher. high. Since the bar-to-charge ratio of a certain weight is much smaller than the surface area of ​​the weight ball, the efficiency and efficiency of the bar mill is lower than that of the ball mill in the second stage of fine grinding;
3) In some cases, it can be used to make a small crush instead of a short-head cone crusher. When dealing with softer or less hard ores (especially viscous ores), grinding a 19-25 mm (or even 32 mm) ore to a 6-10 mesh with a rod mill than with a short cone cone The machine and the screen are simple in configuration and low in cost, and can simplify the dust removal in the crushing workshop. For hard ore, it may be economical to use a short-head conical crusher and a screen to close the road. In the design, the choice of ball milling or rod grinding, mobile crusher , energy-saving ball mill and other sand making equipment must be compared according to the specific circumstances to determine.
The rod mill is driven by the motor through the reducer and the peripheral large gear reduction drive or by the low speed synchronous motor directly through the peripheral large gear reduction drive to drive the cylinder to rotate. The cylinder is filled with a suitable grinding medium - steel rod. The grinding medium is lifted to a certain height under the action of centrifugal force and friction force, and the grinding equipment such as Henan Hongxing Machinery and energy-saving ball mill falls in a falling or leaking state. The material to be milled continuously enters the inside of the cylinder by the feeding port, is crushed by the moving grinding medium, and discharges the product out of the machine through the overflow and continuous feeding force to carry out the next process operation.
Rod mills are available in both dry and wet versions and can be selected according to your actual situation. For the processing of quartz sand, dolomite, monazite and other products, the mill can be equipped with a magnetic separator to remove iron .
