Preliminary Understanding of Rod Grinding Mill

Add Time:15/02/2014

Rod grinder is generally used in coarse grinding, which grinds ores with the entire rod instead of some points of rod. Hence, the acting force of rod mill is quite even. Its feeding granularity is 20 to 30 mm and product granularity is 3 to 0 mm. Rod mill is named because of its loaded grinding medium which is steel bar in the cylinder, which can be divided into dry and wet type. The customers can choose according to actual situation. The generally used type is wet overflow rod grinder. It's widely used in artificial sand, ore dressing plant, chemical plant, electric power department and so on.

Applicable range of rod grinder

1. It's widely used in e-election of tungsten tin ore and other rare metal ores, magnetic dressing plant, quartz sand factory and so on.

2. It's broadly applied as primary grinding equipment, which has higher production capacity and efficiency.

3. It can replace short-head cone crusher for fine crushing in some cases.

It can be seen that rod mill has quite wide applicable ranges, which can not only be used as grinding equipment, but used as crushing equipment in some cases. Structure of rod mill is basically the same to ball mill. The main difference is that rod mill doesn't use grid plate to discharge ores, but use open-type, overflow type and peripheral type discharging devices. The grinding medium of rod mill is steel bar rather than steel ball.

The technological characteristics of rod grinding mill

1. Saving power. The rod mill can save more than 40% of power than traditional grinding equipment.

2. Using advanced and controllable feeding and discharging technology. Rod mill is equipped with suitable grinding medium combining with actual grinding materials of users, which changes surface contact of traditional ball mill into line contact, which makes discharging granularity evener and yield higher.

3. Adjustable discharging fineness. Through simple adjustment, the customers can change discharging granularity. The rod mill is equipped with fineness control device, which can adjust discharging fineness.
