Superfine Vertical Mill

HLMX Superfine Vertical Mill
Top equipment of superfine powder large-scale producing. Breaking through the bottleneck of ultrafine powder processing capacity. Your best choice for large-scale production of ultrafine powder

HLMX Superfine Vertical Mill is large-scale non-metal mineral superfine powder mill developed by Hongcheng based on HLM Vertical Mill and introduction of foreign advanced technology. Hongcheng HLMX Vertical Mill applied static and dynamic classifier, product fineness can be adjusted between 325 mesh to 2500 mesh (5μm-10μm), maximum capacity reach 20t/h. The equipment is widely applied in non-metal mineral superfine powder processing, such as limestone, calcite, marble, coarse whiting, kaolin, barite, bentonite, pyrauxite. It is a high efficiency and low cost powder processing equipment.

The traditional ultra-fine powder-processing equipment,due to its low production capacity, is unable to meet the requirements of large-scale production to satisfy the increasing great market demand. Combining several decades of powder mill R&D and production experience and by introducing advanced technology from Taiwan and Germany, Honecheng has designed and developed the HLMX Superfine Vertical Mill based on HLM Vertical Mill. It becomes the first choice for large-scale production of ultrafine powder by solving the issue of low production capacity of traditional superfine mill.
The HLMX Superfine Vertical Mill, with static and dynamic separator, can produce powder with a fineness ranging from 325mesh(40μm)to 2500 mesh(5μm). It can be widely used in chemical, metallurgy, non-metallic mining industries for grinding limestone, calcite,  marble, calcium carbonate, kaolin, barite, bentonite, pyrophyllite etc. HLMX Superfine Vertical Mill is capable of providing high qulity filers and additives used in the papermaking, segments, plastic, rubber, pigment,printing ink, PVC and so on.

The working principle of HLMX Series Roll Mill
The motor drives the reducer to rotate the millstone, the raw material is sent into the center of the millstone from the air lock rotary feeder. Under the effect of centrifugal force, the material moves to the edge of the millstone. Material than be ground by the force of the roller and smashed under extrusion, grinding and cutting. At the same time, air is blew up around the millstone and bring up the ground material. The air will blow the coarse material back to the millstone. 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, other coarse powder will be brought down to the millstone by the blade of classifier and be ground again. The circulation like this is the overall process of grinding.
When moving together with the materials to the fridge of the grinding plate, due to its weight, the tramp iron cannot be raised by air flow but falls into the lower mill chamber and then is scraped into the slage outlet to be discharged by the scraping plate. This efficiently ensures the quality of finished powder product.
Rotor speed of the multi-rotor classifier is easy to adjust to achieve conforming powder products of various fineness. 
The anatomy of HLMX vertical mill
Grinding roller: Main component used for crushing and grinding materials. Together with the liner plate on the grinding plate, it can provide an effective grinding area.
Grinding Plate: Component fixed on the output shaft of the reduction gear and where the grinding roller grinds materials.
Classifier: A high efficient and energy saving powder separation device. Single rotor or multi-rotor is used to producing adjustable particle sizes due to the actual requirement.

Application Range
With scientific & reasonable design and abovementioned unique advantages, HLMX ultra-fine vertical mills are applied widely in metallurgical, chemical, and non-metallic industry, for grinding of various materials, such as limestone, gypsum, coal, barite, calcite etc. It is large-scale equipment breaking through the bottleneck of ultrafine powder processing capacity. It is your best choice for large-scale production of ultrafine powder.
