INTRODUCTION OF PRODUCT

Guilin Hongcheng HLMX series superfine calcium carbonate vertical grinding mill is a large-scale high fine vertical grinding mill suitable for the development of non-metallic mining industry in China, which draws on the technology of Germany, Japan and Taiwan. Hongcheng HLMX series superfine calcium carbonate vertical grinding mill adopts dynamic, static combined classifier, the fineness of products can be adjusted between 7 μm~45 μm. Secondary classifying system with fineness up to 3μm. Hongcheng HLMX series can be used in the processing of calcium carbonate superfine powder. High efficiency, high yield, environmental protection and energy saving. High efficiency, high yield, environmental protection and energy saving.

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.

Product quality is stable and excellent. The material stays in the mill for a short time, easy to detect the particle size distribution and composition of the product, and reduce the repeat grinding rate, the finished product contains less iron, high whiteness and purity. In the process of grinding, adding trace amount of grinding aid without affecting the quality of finished products can improve the added value of products. Easy to maintain and low operating cost. The grinding roller can be turned out of the machine by hydraulic                                  device, large maintenance space. The mill can be started without raw material on the grinding table. The                            roller and grinding table are made from special material for long working life.

Easy to maintain and low operating cost. The grinding roller can be turned out of the machine by hydraulic device, large maintenance space. The mill can be started without raw material on the grinding table. The roller and grinding table are made from special material for long working life.

High reliability. The roller limit device is adopted to avoid the violent vibration caused by the breaking of materials during working. Adopt new grinding roller sealing device, the sealing is more reliable, and there is no need to seal the blower, reduce the oxygen content in the grinding mill, and the anti-explosion performance is better.

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

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.

MILL 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.
