The 1.83 x 7 m ball mill, a standard model for industrial grinding equipment, boasts technical parameters designed to fully demonstrate efficiency and adaptability. With a drum diameter of 1.83 meters and a length of 7 meters, it utilizes an edge drive mechanism, operates at a drum speed of 23.9 rpm, has an effective volume of 16.24 m³, and can load 22.3 tons of grinding media. Its core power system features a JR138-8 245kW electric motor and a ZD60-8-I reducer, creating a 4.5 speed ratio and ensuring stable operation in both dry and wet grinding conditions.
The split-chamber design (typically two chambers) combined with steel balls or alumina liners of varying specifications enables multi-stage grinding of materials. The resulting particle size ranges from 0.074 to 0.8 mm, meeting the requirements for finished products with a fineness of ≥300 m²/kg. Particularly noteworthy is the optimized structure of the lifting plate and discharge spiral drum, significantly improving material flow efficiency. Dry grinding maintains a stable output of 6-8 tons/hour, while wet grinding reaches 15-25 tons/hour. The machine weighs 39 tons and utilizes a welded Q235-B steel cylinder and a ZG270-500 hollow shaft, ensuring both structural strength and wear resistance, ensuring reliable continuous production.
The 1.83 x 7 meter ball mill, with its modular design, demonstrates broad application value across multiple industrial sectors. In the mineral processing industry, this equipment is commonly used for wet grinding of metal ores such as copper and iron ore. Its hydraulic classification system achieves mineral separation, and its 15-25 tons/hour production capacity meets the continuous production needs of medium-sized mineral processing plants. In the building materials industry, it is often used for dry grinding of cement raw materials or lime. Combined with a pneumatic classification system, it produces a stable powder fineness of 300 m²/kg or higher. Its 6-8 tons/hour efficiency significantly reduces energy costs. In the preparation of ceramic raw materials, the combination of alumina balls and rubber liners can reduce iron pollution and improve the working environment by reducing noise. This model is also highly used in the chemical and refractory industries. Its dual-chamber design allows for flexible adjustment of the grinding media ratio to meet diverse process requirements, from coarse grinding to ultrafine powder.
