INTRODUCTION OF PRODUCT

Gypsum has been widely promoted and applied in different fields. Gypsum is highly valued in the fields of construction, agriculture, thermal power plant, chemical industry and so on. It forms a huge emerging industry and promotes the rapid development of circular economy.

The application demand of superfine gypsum powder is increasing, and the traditional superfine powder processing equipment has low production capacity, which cannot meet the requirements of large-scale production.

SUPERFINE GYPSUM POWDER GRINDING MACHINE HLMX adopts dynamic and static combination classifier, the fineness of the product can be adjusted between 7 μm~45 μm. Secondary classifying system with fineness up to 3 μm.

This product can be used to process gypsum ultrafine powder. High efficiency, high yield, environmental protection and energy saving are the characteristics of our products.

Finished product size: 3-45 μm

The production capacity is 4-40t/h

ADVANTAGES AND FEATURES

Grinding powder high efficiency, energy saving. Specially designed roller sleeve and liner grinding curve, high grinding efficiency; The output of single machine is up to 40t/h. Off-peak electricity is available.                                      

Energy saving 30%-50% compared with ordinary mill.

Easy maintenance and low operating cost. The grinding roller can be turned out of the mill with a hydraulic device to replace the roller sleeve liner. The roller sleeve can be turned over and used. HLMX series mills can be started without load. The grinding roller and the grinding disc liner are made of special materials and have a long service life.

The comprehensive investment cost is low. Set crushing, drying, grinding, conveying in one of the technological process is simple, the number of equipment is only 50% of the ball mill. It can outdoor layout, and construction cost is low.

Product quality is stable and excellent.The material bed milling principle adopted by the HLMX series mills effectively reduces the repetitive milling rate, and the finished product contains less iron and has high whiteness and purity. In the process of grinding, the added value of the product can be improved by adding a small amount of grinding AIDS without affecting the quality of the finished product.

High reliability. The roller limit device is used to avoid the severe vibration caused by the material interruption during the working time of the mill; the new type of roller sealing device is adopted to effectively reduce the oxygen content in the mill and the explosion suppression performance is better.

Environmental protection. The whole HLMX vertical mill system has low vibration and low noise.

The whole system is sealed and operates under full negative pressure without dust overflow

High degree of automation. Adopt PLC automatic control system, and can realize remote control, reduce labor cost.

GYPSUM POWDER GRINDING MACHINE STRUCTURE:

The complete system of HLMX series superfine calcium carbonate vertical grinding mill is mainly composed of main machine, feeder, classifier, blower, piping device, storage hopper, electric control system, collection system, etc.

WORKING PRINCIPLE

The motor drives the reducer to drive the grinding disc to rotate. The material to be grinded is sent to the center of the rotating grinding disc by the locking air feeding equipment. Under the action of centrifugal force, the material moves to the periphery of the grinding disc and enters the grinding roller table.

Under the action of grinding roller pressure, the material is crushed by extrusion, grinding and shearing.

When iron and other sundries mixed with materials move to the edge of the grinding disc, they cannot be blown by the wind due to their own weight and fall into the lower cavity of the mill and are scraped into the slag discharge mouth by the scraper for discharge.

SECONDARY CLASSIFYING SYSTEM

The secondary classification system consists of superfine classifier, fan, dust collector, hopper, screw conveyor, pipe and other equipment. The ultrafine classifier is its core equipment. HLMX series superfine vertical mill is equipped with secondary air separation grading system, high powder efficiency, can effectively separate coarse powder and fine powder, separation fineness can be up to 3 μm, can achieve a vertical mill production of different specifications of products, but also fast and stable production of the same fineness of products.

FEATURES OF THE SECONDARY CLASSIFYING SYSTEM

High classification efficiency: the classifier and fan adopt frequency conversion speed regulation control. By adjusting the speed of the classifier and fan impeller, the fineness of finished products with different specifications can be obtained quickly, and the classification efficiency is high.

Classifier: An efficient and energy - saving classifier. Single rotor and multi – rotor can be used, fineness can be adjusted.

Big range of product fineness: Fine particles of vertical grinding materials can be separated, and the fineness range of separation is from 3um to 45um.
