The 2136 rod mill is a widely used grinding equipment in small and medium-sized mineral processing plants and the building materials industry. The "21" in its model number indicates a cylinder diameter of 2.1 meters, and "36" represents a cylinder length of 3.6 meters. This equipment primarily uses steel rods as grinding media to impact and grind materials, suitable for coarse grinding or the preparation of medium-fine products.

In terms of technical parameters, the installed power of the 2136 rod mill is typically 155–185 kW, with a processing capacity of approximately 10–45 tons/hour. The specific capacity depends on the material hardness, feed particle size, and product fineness requirements. Its feed particle size generally does not exceed 25 mm, and the output particle size is mostly controlled between 0.8 and 2 mm. It is particularly suitable for coarse grinding of metallic ores such as tungsten, tin, gold, and copper, and can also be used for processing non-metallic minerals such as glass raw materials and quartz sand.

Compared to ball mills, rod mills have the advantages of uniform product particle size and less over-grinding, making them particularly suitable for processes requiring concentrated particle size distribution and avoiding severe mud formation. In the pretreatment stage before gravity or magnetic separation, the 2136 rod mill effectively liberates valuable minerals, improving subsequent separation efficiency.

Furthermore, this equipment features a simple structure, stable operation, and convenient maintenance, making it suitable for use in areas with limited power supply or low levels of automation. With increasing demands for energy conservation and consumption reduction in mineral processing, the 2136 rod mill is often combined with classifying equipment (such as spiral classifiers or high-frequency screens) to form a closed-loop circulation system, thereby improving grinding efficiency and reducing energy consumption.

In conclusion, the 2136 rod mill, with its reasonable specifications, stable performance, and wide adaptability, continues to have significant application value in small and medium-sized mines and specific industrial sectors.
