The Rod Mill In The Mining Industry Finely Crushes And Grinds Ores

 
The rod mill is an important industrial equipment, mainly used for fine crushing and grinding of materials. Its working principle is that the motor drives the cylinder to rotate. Inside the cylinder, steel rods are installed as grinding media. Under the impact and grinding action of the steel rods, the materials are crushed.
 
Structural composition
 
It is mainly composed of a motor, a main reducer, a transmission part, a cylinder part, a main bearing, a slow-speed transmission part, a feeding part, a discharging part, a ring seal, a thin oil lubrication station, large and small gear jet lubrication, a foundation part, etc.
 
Working principle
 
The motor is driven by a reducer and the surrounding large gear for reduction transmission, or directly drives the cylinder to rotate by a low-speed synchronous motor.
Under the action of centrifugal force and friction, the grinding media are lifted to a certain height and then fall to crush the materials.
 
 
Application field Of Ore Grinding Mill
 
Mining: It is used for crushing and grinding ores, providing basic raw materials for subsequent mineral processing procedures.
Building materials: In the cement production process, it is used for grinding raw materials such as limestone and clay.
Chemical industry: Conduct refined processing on chemical raw materials to ensure product quality and performance.
 
Feature Of Ore Grinding Mill
 

• The cylindrical mill adopts the driving type edge-driving, center-driving, edge-driving with multi-point meshing, etc; driven by asynchronous motor reducer pinion and gear as well as synchronous motor air lclutch pinion and gear.
• Generally supported by static-dynamic pressure bearing on both ends. Fuuly closed self-aligning 120o osculation rocker bearing is used. Also single or double slipper staic- dynamic bearings can be used. The bush is made by NC machine.
• The large open gear is designed using AGMA standard, Equipped with reliably sealed gear housing and grease ahtomatic spraying lubrication system.
• The shell is key part of a mill. Carry out finite element analysis on it with computer to ensure the reliable operation;
• The shell is automatically welded, ultrasonic inspected, wholly annealed and machined by large special machine tools on one chucking; there special seal on static-dynamic connection parts , ch as feed and discharge hoper, trunnion, etc, to prevent oil and slurry leakage;
• The liner is of wear-resistance material mad by our company, wich has been specially heat-treated, with high hardness and long service life. Also other wear-resistance casting or rubber liner can be used;
• There are slow speed drive for medium and large mill;
• The high and low pressure lubricating station is equipped for medium and large mill;
• The control and protection system is controlled by PLC.
