Rod Mill

CITICIC can produce cylinder diameter below 8m rod mills. The rod mill is used for primary ore grinding in manual stone sand, ore dressing, chemical industry, electric power and other industries.We have first-rate rod mills research and design team, perfect test and inspection means and excellent rod mills manufacturing equipment and manufacturing technology, and have formed a completerod rod mill experimental research, design, manufacture, detection and service system.

The preparation of ball or pebble mill feed is an important application for CITICIC's rod mills.
The preparation of ball or pebble mill feed is an important application for CITICIC's rod mills. These mills produce a uniform-sized product while minimizing the production of tramp oversize and unwanted fines.
The rod mills accept a feed size up to 2" and produce a typical product size of 5 to 10 mesh when operating in open circuit and as fine as 35 mesh in closed circuit with a screen or other sizing device.
Rod mills Applications
The rod mill, a tumbling mill characterized by the use of rods as grinding media, is used for grinding ores, coal/coke, and other materials for both wet
and dry applications. The rod mill performs best when making products having a top size of 4 mesh to 16 mesh operating in open circuit, or as fine as 35 mesh operating in closed circuit with a screen or other sizing device. The rod mill accepts feed ore as coarse as 1 1/2” top size although better performance is obtained by restricting ore feed size to 3/4”.
Materials too wet for fine crushing and dry screening may be wet ground in a rod mill. Practice has demonstrated the ability of a rod mill to dry grind damp materials that will pack or plug other grinding equipment. and scrap loss are reduced by correct selection of liners for the specific grinding duty. Additional
benefit results from use of a backing material, such as rubber between the liners and the mill shell.

Feature
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 120 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.

Wet Grinding Rod Mills

Historically, rod mills have been used as the first grinding stage after crushing in mineral benefici ation circuits. The rod mill product was further ground in ball mills before separation of valuable minerals from the host rock. With the advent of semi-autogenous (SAG) mills replacing secondary and tertiary crushing as well as first stage grinding,the rod mill has fallen out of favor for new large mineral beneficiation circuits.
A recent application for a trunnion overflow rod mill is in the preparation of coal and petroleum coke slurries for Integrated G
