Rod Ball Mill: Rod Grinding Mill

A rod mill is a mill in which the grinding body is a steel rod. The rod mill is generally a wet overflow type, which can be used as a first-stage open-circuit grinding. It is widely used in the first-grade grinding of artificial stone sand, concentrating plants and chemical power plants.

Rod Ball Mill: Rod Grinding Mill Introduction

rod mill

Rod Ball mill is a key equipment for further grinding after the primary crushing. It is widely used in cement, silicate products, new building materials, wear-resistant materials, fertilizers, ferrous and non-ferrous metals, glass ceramics and other industries.According to the processing technology, it is divided into two grinding ways-the dry and the wet. Besides,wet ball mill can be divided into tabular type and flowing type.

The rod mill is driven by motor with speed reducer and peripheral large gear or low speed synchronous motor with peripheral large gear. The grinding medium --- steel rod is put into the cylinder which is lifted and then fall under the action of the centrifugal force and friction force. The materials entering into cylinder form the feeding inlet are grinded by movable grinding medium and discharged out by overflow and continuously feeding.

Advantages

Advantages of Rod ball mill: Rod Grinding Mill

 

Our company adopts advanced controllable feeding and discharging technology, integrates actual grinding material which should be equipped with proper grinding body to change traditional surface contact into line contact, and this makes discharging size more homogeneous and output higher. So it is widely used in the industries such as refractory material, chemical, metallurgy and glass and so on. And it is used for grinding operation which has a high requirement on homogeneity of grinded products . In recent years, it is also used for sand making in the industry of construction.

Working Principles

Structure and Working Principle of Rod ball mill /Rod Grinding Mill:

Rod mill consists barrel, feeding part, discharging part, bearing part and lubrication system. It can grind all kinds of hard grade of ore and rock materials.

 

Material through the feed device evenly get into the rod mill warehouse. There are different specifications grinding rods in the warehouse of rod mill. The grinding rods adhere to the rod mill cylinder rotating due to the centrifugal force when the rod mill working, then the grinding rods fall down and give the material an heavy impact when the grinding rods reach a certain height. When hit the material, coarse is to be broken firstly, then the smaller.After so many times, we would get fine materials.
