High-Output Rod Mill For Fine Crushing And Grinding Of Materials

The rod mill is a kind of material fine crushing and grinding equipment widely used in industries such as mining, building materials, chemical engineering and power. 

Working principle

The rod mill is mainly composed of the cylinder, main bearing, base, large gear, small gear, helical blades, flange, bearing, hollow shaft, etc. Inside the cylinder, steel rods are installed as grinding media. Materials are ground and crushed by the steel rods inside the cylinder and discharged through overflow or continuous feeding for the next process.

Performance advantage Of Ore Grinding Mill

High output and good discharge: The grinding of materials by the rod grinding medium changes from surface contact to line contact, resulting in more uniform discharge and higher output.

Power saving: Compared with the old-fashioned rod mill, it can save about 50% of power, making energy consumption more economical.

Environmentally friendly production: The structural design reduces the flying out of dust, avoiding environmental pollution and achieving environmentally friendly production.

Long service life: The vulnerable parts and core components are made of high-quality materials, extending the equipment's service life by more than three times.

Application field Of Ore Grinding Mill

Mining: It is used for crushing and grinding ores, providing basic raw materials for subsequent processes such as mineral processing and smelting.

Construction industry: In cement production, it is used to grind raw materials such as limestone and clay to improve the quality of cement. In the processing of sand and gravel aggregates, produce sand and gravel that meet the requirements of construction.

Steel manufacturing: It is used for coarse grinding of ores and processing of raw materials in the steel production process to ensure the quality of raw materials.

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.
