Product information
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.
Main design features:
High quality cast end cover and solid welded cylinder greatly prolong the service life of the equipment.
The design of semi autogenous mill is supported by a complete set of analysis reports, including finite element analysis of rotating body, finite element analysis of oil film of main bearing, AGMA calculation of transmission gear, torque analysis of transmission system and EDEM discrete element analysis of liner.
The equipment has a more efficient and stable full hydrostatic lubrication system.
The equipment has a high degree of automation. It is equipped with PLC control system and one key start, which can monitor the operation status of the equipment in real time.
Main advantages：
After careful design, the semi autogenous mill of Sinoma Liyang can stably provide higher output, safe, reliable, high quality and high efficiency. Our semi autogenous mill can achieve higher output at lower cost.
Sinoma Liyang semi autogenous mill has complete specifications and is widely used. We provide semi autogenous mills with diameters ranging from 4.0m to 10.37m and maximum power up to 12000kW. You can easily find the specifications you need.
