Shanghai Pohill Machinery
The ball mill is one of our core products, an efficient grinding equipment mainly composed of cylinder, end cover, bearing, transmission device and other parts. This series of ball mills adopt advanced design concepts and processing technology, with stable operation, low energy consumption, high grinding efficiency, simple operation and maintenance and other characteristics. It is suitable for grinding various ores and other materials, and can be widely used in mineral processing, building materials, chemical and other industries. According to different discharge methods, it can be divided into grid type and overflow type; According to the cylinder shape, it can be divided into short cylinder ball mill, long cylinder ball mill, tube mill and conical mill.
Grinding of metal and non-metal ores
Grinding of cement clinker and building material feed
Grinding of chemical raw materials
Grinding of ceramic and glass raw materials
When the ball mill is working, the motor drives the cylinder to rotate through the reduction device. The grinding medium (steel balls, steel segments, etc.) in the cylinder is lifted to a certain height under the action of centrifugal force and friction, and then falls in a falling or cascading state. Materials enter the first chamber of the mill uniformly through the feeding hollow shaft screw of the feeding device. The chamber is equipped with step liners or corrugated liners and steel balls of different specifications. The rotation of the cylinder generates centrifugal force to lift the steel balls to a certain height and then fall, producing heavy impact and grinding effect on the materials. After the materials are roughly ground in the first chamber, they enter the second chamber through the single-layer partition board. The chamber is inlaid with flat liners and steel balls to further grind the materials. The ground materials are discharged through the discharge grate plate to complete the grinding operation.
