Specifications

Stone mill/grinding machine/slag vertical mill/slag and coal vertical mill / corn grinding mill machine

Introduction

Vertical mill is one kind of roller mill.As requested , it may equip with 3 or 4 rollers.Each roller is composed of fixed roller, support of installation rocker arm and hydraulic system.Motive force unit is in the components, three components around mill disc.

Work principle

Raw material feed into discharge pipe through rotary discharger.Discharge pipe enter into the mill through the side or the center of the center of the separator.Material will fall into the center of mill disc with the help of gravity and air flow.Mill disc connect with the reducer constantly.Constant speed rotation of mill disc.There inclined mill roller will bite material and pulverize.Grind material with the function of pressure and friction.

Centrifugal force will disc will make pulverized material at the edge of mill disc from the middle of mill disc.Material off mill disc will enter into hot gas in the mill through air ring.Via the middle of the mill shell and enter into the separator.During the process, material will exchange hot gas.The moisture will be evaporated.The rest moisture can reach 1%. Unpulverized material as request will be selected by the Separator and send back mill disc.
