Rod mill

Processed material: cement, ore, slag, steel slag, etc.

Capacity: 2.4-250t/h

Motor Power: 75-1400kW

Fineness: 0.833-0.147mm

Process introduction

Rod mill has a wide application range, especially when grinding in some special conditions:

1. To avoid the damages caused by over-crushing, gravity separation plant or magnetic separation plant for tungsten-tin ore and other rare metal ore always uses rod mill.

2. In some cases, rod mill can perform crushing instead of short head cone crusher. When processing soft or low-hardness ore, rod mill can grind 19-25mm (even 30mm) ore into 6-10mm. It is more simple and more cost-saving than the closed combination of short head cone crusher and separator, and moreover it simplifies the dust removal in ore-breaking workshop. However, short head cone crusher combining closely with separator is more economical when processing hard ore.

Thus, when making a project scheme, ball mill and rod mill must be selected according to actual conditions.

CHAENG Rod mill can effectively control the inlet and outlet of materials, with advanced technology and obvious advantages:

1. Power saving

Saving over 40% of power than other equipment in the market.

2. uniform discharge size, high output

Adopt advanced controllable feed-discharge technology and use proper grinding medium according to actual grind materials. Instead of surface-contact mode of traditional ball mill, line-contact mode of rod mill makes finished size more uniform and decreases coarse particles and slime.

3. Adjustable discharging fineness, no over-grinding

The discharging fineness can be adjusted through simple adjustment. Inside the rod mill is installed a fineness control device, and discharging position has screening device. Those two kinds of devices can guarantee that over-grinding will not occur, and substandard product will not mix into finished product. Thus, finished product produced by rod mill is more uniform and over-grinding problem is less.
