Specifications

high pressure overhang roll mill:
1.fine powder produced
2.low energy consumptiono
3.high efficiency
4.CE certificate

Introduction

High pressure overhang roll mill is used for grinding the barite, limestone, kaolin, ceramics, and slag, etc, with the hardness below scale 9.3 of Mohs and 280-odd sorts of non-inflammable and non-explosive stuff in the trades of mining, metallurgical industry, chemical engineering and building material for high fine powder generating and processing. The particle size of finished product can be adjusted from 80 to 325 meshes at random and the particle size of part materials can reach 2000 meshes at the maximum.

Features

1.Compared with other grinding mill, the output can increase 10-20% under the same condition.   
2.Minerals Moh's hardness: below scale 9.3       
3.The final products size is extensive, from 0.613mm (30mesh) to 0.033mm (425mesh), and the finest powder can reach to 0.013mm (1000mesh).      
4.The dust-removing effect can fully conform to the national standard.       
5.The grinding equipments adopt lapping multilevel seal, which is very effective.

 

Working principle 

When it is put into use, the materials to be grinded are put into the main frame through the feed-in bin on the side cover. Then it revolves round the vertical axis line by the milling roller hung on the star rack. With the centrifugal force by rotation, milling roller wings outside and presses fast on milling rings to make relieving tool carry materials between milling roller and ring, thus the materials are crushed by the rolling and milling of the milling roller.
