The rod mill is named after the grinding body loaded in the cylinder is a steel rod. The rod mill is generally a wet overflow type and can be used as a first-level open-circuit grinding. The rod mill is widely used in metal and non-metal mines. And water conservancy and building materials departments to grind various ores or rocks.
Tamanho da saída: 0.833-0.147mm
Tamanho da alimentação: ≤25-≤50 mm
Application:
Widely used for artificial stone sand making, mineral processing plants and chemical plants
Rod ball mill usage
1. In the gravity separation or magnetic separation plant of tungsten-tin ore and other rare metal ore, as well as the quartz sand plant, rod mills are often used in order to prevent the harm caused by “over crushing”.
2. When two-stage continuous grinding is used, if the first stage is from 20-6mm grind to 3-1mm when the rod mill is used as the first-stage grinding equipment, the production capacity and efficiency are higher.
3. In some cases, the rod mill can replace the short-head cone crusher for fine crushing.
Rod ball mill features
1. The characteristic of the rod mill is that during the grinding process, the grinding medium is in line contact with the ore, so it has a selective grinding effect;
2. The particle size of the product is relatively uniform, and there are few ore particles after crushing;
3. When used for rough grinding, the processing capacity of the rod mill is greater than that of the ball mill of the same specification, and vice versa;
4. Stable operation, energy saving and consumption reduction, and high output.
Rod mill working principle
Rod mill Sand is driven by the motor through a reducer gear reducer and the surrounding low-speed synchronous motor drive or directly through the surrounding large gear reduction drive, the drive cylinder rotation.
A cylinder body with an appropriate grinding media, such as steel bars, is needed. Grinding media, in the role of centrifugal force and friction, has been elevated to a certain height and thrown down or drained off the state.
Wash milled material from the mine mouth into the cylinder continuously inside the movement shattered grinding media and through the overflow and continuous power to the mine product from the plane to the next section of processes operating.
