1. Semi autogenous mill is an ideal choice for processing raw ore or discharging ore by coarse crushing crusher. It has the advantages of high crushing ratio, good reliability and large processing capacity.
2. It is widely used in mineral processing, metallurgy, electric power, building materials, chemical industry and other industries.
3. The semi autogenous mill can replace some crushing and screening operations while grinding, which can simplify the process, reduce investment and maintenance costs, save energy and increase production.
Brief:
Semi autogenous mill is usually called SAG mill, which can replace some crushing and screening operations while grinding. It is a common equipment in modern concentrators, which can directly produce finished products or provide materials for the operation of the lower ball mill. The grinding medium (steel ball) of semi autogenous mill is 6-15%.
Sinoma Liyang has rich experience in mill manufacturing, complete specifications and wide applications of semi autogenous mills, which can well meet the needs of various mineral processing.
The diameter of semi autogenous mill of Sinoma Liyang ranges from 4.0m to 10.37m, and the maximum power is up to 12000kW. Our product R & D team is constantly improving the design of semi autogenous mill and optimizing the scheme according to the specific needs of customers, so as to provide more reliable, safe and efficient equipment.
Working Principle:
The material enters the cylinder from the center of the feed end cover. The motor drives the rotary part equipped with grinding medium (steel ball) and materials to rotate through the transmission device.
Proper grinding media (steel balls) and materials are loaded in the cylinder. Under the action of centrifugal force and friction, the grinding media and materials are lifted to a certain height with the rotation of the cylinder, and then thrown off at a certain linear speed.
The materials in the cylinder are crushed by the impact of steel balls (materials) and the additional crushing and grinding stripping between materials, between steel balls, and between steel balls (materials) and cylinder liner, fully exposing the fresh surface and fully mixing. Finally, the ground qualified materials are discharged from the mill through the discharge port of grid plate at the discharge end of the cylinder to complete the grinding process.
Technical data:
Type | Diameter | Effective length | Installed Power |
