Pre-Grinding Vertical Mill

Product Introduction

ZJTL-Y pre-grinding vertical mill is that my company in absorbing fully foreign vertical mill as the basis of pre-grinding cement complete set technology bold innovation key researchdeveloped a new type of grinding equipment. The system set fine grindinggrindingpowder collectiontransport in onecompared with roller millit is of high grinding efficiencylow power consumptionthe system capacity is lower than roller mill systemespecially the maintenance fee per year is only 50% of roller mill system.It is with significant advantage of simple technological processa small covering area no dust pollution low abrasion low maintenance and reliable operationetc.

Structure Principle

ZJTL-Y pre-grinding vertical mill is by 3 symmetrical rotating cone roller under the effect of high pressure with grinding disk rotating the material on the mill is to be sheared extrusion crushed and ground with flat & tapered roller shape design and bed grinding technologygreatly reduce the unit energy consumption widely used in building material metallurgychemical industryetc.It can cooperate with existing ball mill to form process system of circular pre-grinding and circular classified pre-grinding. Integrated grinding power consumption reduced by 30%-40%yield increased by 50%-100%.

ZJTL-Y pre-grinding vertical mill is mainly composed of motorreducermillrollerhydraulic device lubrication deviceetc. Material is fed into the mill inlet valve to central due to the mill rotating to produce centrifugal force material is dumped into the grinding zone and then crushed and ground by the pressure roller. Shredded material pass by the millstone fell into the inside of the low shell is scraped and discharged from discharge valve by the scraping plate.

Technical Advantage

Small sliding pressure difference High grinding efficiency

Tongli cement mill pre-grinding vertical mill is with flat and cone roller structure together. The relative sliding difference is small between grinding disk and roller so that the production is higher compared with other forms pf roller mill under the condition of the same specification.

Lift the roller automatically Start the roller no-load

Roller lift and down automatically without artificial material no-load start to reduce the starting of motor ability. Roller can use double roller cylinder outside the shellboth convenient for installation and maintenance.

Little wear long services life

Reserved space between the roller and mill and is equipped with proximity switch to carry on the limit which can avoid metal friction between roller and plate.Using forced lubrication of roller bearing to protect the bearing. Roller set up several bearing seal and is applied for a patent to prevent oil spills.In order to prevent the invasion of the micro powder also specially equipped with seal fan.

Production increase&consumption reduce Effect significant

The new technology of extruding and shearing force grinding is widely used by using this grinding process and more significant grinding effect than existing roller mill. It can help increase the cement clinker production capacity increase by more than 50% power consumption reduced by 30%-40% and achieve the goal of energy conservation and emissions reduction and high efficiency grinding high productivity and low consumption. Composed with ball mill into grinding system product fineness wide range adjustableeffectively improve cement compressive strength.
