Guilin HongCheng grinding mills are suitable for grinding diverse non-metallic mineral materials with Mohs hardness below 7 and moisture below 6%, the final fineness can be adjusted between 60-2500mesh. Applicable materials such as marble, limestone, calcite, feldspar, activated carbon, barite, fluorite, gypsum, clay, graphite, kaolin, wollastonite, quicklime, manganese ore, bentonite, talc, asbestos, mica, clinker, feldspar, quartz, ceramics, bauxite, etc. Please contact us for details.
High grinding efficiency and energy saving. The capacity of one unit can reach 40t/h. Using single and multi-head classifiers, no need to using secondary air separation and classification, and it can save 30% -50% energy consumption than ordinary mills.
The final product has stable quality. Short dwell time of the material to be ground, reducing repeated grinding, it is easier to detect particle size distribution and composition of products, the few iron content is easy to remove to guarantee high whiteness and purity.
Environmental Protection. HLMX vertical mill has minimum vibration and noise. The whole sealed system works in full negative pressure guarantees no air pollution in the workshop.
Ease of maintenance, lower operating cost. The grinding roller can be taken out from the machine through the hydraulic device, a large space for maintenance. The two sides of the roller shell can both be used for prolonging the working life. The mill can run without raw material on the grinding table, which erases the difficulty in starting.
High reliability. The roller limit device is used to prevent vibration caused by material interruption during mill running. The newly-designed roller sealing component ensures the reliable sealing without sealing the fan, which can lower the oxygen content in the mill to prevent the possibility of explosion.
The mill integrates crushing, drying, grinding, classifying and conveying materials in one continuous, automated operation. Compact layout requires less footprint which is 50% of the ball mill. It can be installed in outdoors, lower construction cost to save initial investment.
High degree of automation. It adopts the PLC automatic control system and can realize remote control, which is easy to operate, convenient to maintain, and reduces labor costs.
Designed and built for professionals
As the HLMX 2500 Mesh Superfine Powder Grinding Mill works, the motor drives the reducer to rotate the dial, the raw material are delivered to the center of the dial from the air lock rotary feeder. The material moves to the edge of the dial due to the effect of centrifugal force and than be ground by the force of the roller and smashed under extrusion, grinding and cutting. Simultaneously, the hot air is blew up around the dial and bring up the ground material. The hot air will dry the floating material and blow the coarse material back to the dial. The fine powder will be brought to the classifier, and then, the qualified fine powder will flow out the mill and be collected by dust collector, while the coarse powder will fall down to the dial by the blade of classifier and be ground again. This cycle is the whole process of grinding.
Secondary Classifying System
The secondary classifying system includes superfine classifier, fan, dust collector, hopper, screw conveyor and pipes. The classifier is the core machine of the whole system. HLMX series superfine vertical mill has equipped with the secondary classifier system, which is capable to efficiently separate coarse powder from fine powder to obtain products in different fineness between800 mesh to 2000 mesh.
Features of the secondary classifying system
High classifying efficiency: The classifier and the fan are controlled by frequency conversion speed regulation. By adjusting the speed of the classifier and fan impeller, various fineness of stable and reliable end product can be obtained rapidly. The classifying efficiency is high.
Classifier: A high efficient and energy saving powder separation device. Single rotor or multi-rotor is used to producing adjustable particle size due to the actual requirement.
Wide range of fineness: The classifying system is capable of selecting fine particles from the materials. The fineness can range from 800 mesh to 2000 mesh. With the secondary classifying system it can get different particles size, and it can also get same particle size in high throughput.
