Product Description

Introduction

RFLM SERIES ULTRAFINE VERTICAL ROLLER MILL

 

Equipment introduction

 

RFLM series ultrafine vertical roller mill is an ultrafine vertical roller mill researched and developed by Ruifeng Powder Equipment Co., Ltd. based on years of experience and in-depth research on powder processing technology, it is able to process ultrafine powder that requires secondary classification in the past in one time, reducing energy consumption by 35% and above, minimizing the inventory of coarse powder requiring secondary classification, and lowering raw material cost; through continuous optimization and improvement of various parts, the vertical mill is possessed with high reliability and extremely low downtime, and is widely applied in the field of large-scale processing of ultrafine powder including calcite, barite and talc.

Machine working principle

The main motor drives the grinding disc rotating through the reducer, and materials are fed to the main unit of the roller mill through the screw conveyor and fall onto the center of the grinding disc under the action of gravity, at the same time, the air generated by the blower enters the roller mill through the air inlet Under the action of centrifugal force, materials move evenly from the center to the edge of the grinding disc; when passing through the roller way on the grinding disc, large material blocks will be crushed by the grinding roller, while fine materials will be compacted and form a material bed for inter-particle crushing. Crushed materials will continue to move to the edge of the grinding disc until being blown upward by the air jet guided by the nozzle ring around the grinding disc, while coarse materials will fall back to the grinding disc under the action of gravity for secondary grinding; fine materials carried by air flow wi enter the the classification system above the main unit for screening and classification. With the classification rotor blades working, coarse materials will be unable to pass through and fall onto the grinding disc for regrinding, while qualified fine powder will be carried by the air flow, move out from the classification system, and enter the dust removal system through an external pipeline; by passing through the dust remover, the materials will be separated from the air flow and collected as finished products. Besides, during grinding, debris contained in the material and large grain-size material will be separated and discharged to the slag discharge port by the scrapper, so as to ensure the quality of finished products. In addition, the pressure of the grinding roller can be adjusted by regulating the pressure of the hydraulic system, so as to adapt to different materials with different hardnesses; by adjusting the rotor speed of the multi-rotor classification system, the fineness for classification screening can be adjusted, so as to obtain qualified finished products of different specifications.
