CLUM Ultra Fine Vertical Mill Professional Superfine Stone Powder Production Equipment

About CLUM Ultra Fine Vertical Mill


There is an increasing demand for ultra fine powder applications, and the traditional ultra fine powder processing equipment has low capacity, which can no longer meet the requirements of large-scale production in the field of ultra fine powder. Clirik CLUM series ultra fine vertical mill is a large-scale vertical grinding equipment which developed by clirik on the basis of vertical grinding machine, which is suitable for the development of non-metallic mineral industry. It breaks through the bottleneck of ultra-fine powder processing capacity, can replace imported equipment, and becomes an ideal equipment for large-scale production of ultra fine powder.

Clirik ultra fine vertical mill can be adjusted between 45um and 7um, and the maximum fineness can reach 3um by adopting the secondary classification system. It can be widely used for ultra fine grinding and processing of non-metallic mineral products such as limestone, calcite, marble, heavy calcium, kaolin, barite, bentonite and pyrophyllite. It is a high-efficiency, high-yield, environmental protection and energy-saving ultra-fine powder processing equipment.

CLUM Ultra Fine Vertical Mill Advantages


Excellent finished product quality

Using the vertical abrasive layer grinding principle, the material stays in the mill for a short time, reducing repeated grinding, so the iron content in the product is very small, and the whiteness and purity of the product are high. Grain size of finished product is less than 2 μ M U.M powder content can reach 70%, achieving 325 mesh low residue, and adding secondary powder separation to select more fine-grained finished products.

High grinding efficiency

The speed of the main engine is adjusted by frequency conversion, which is widely applicable to a variety of materials. The specially designed grinding curve of roller sleeve and liner plate is easier to form the material layer than the ordinary vertical mill, and can be grinded to the required product fineness at one time. Mechanical and electronic double limit protection devices are used to effectively prevent the roller sleeve from directly contacting with the grinding disc lining plate and avoid destructive impact and violent vibration.

High level of environmental protection

Low vibration and noise. The equipment is sealed as a whole and works under negative pressure. There is no dust spillover. The environment is clean and the environmental protection requirements are higher than the national standards.

Good economic benefits

The principle of multi head powder concentrator, and each rotor adopts frequency conversion speed regulation, the fineness of the finished product can be realized within the selected range, without secondary sorting, and there is no inferior material. Based on the principle of ultra-fine grinding and multi head powder selection, when producing products of the same fineness grade, compared with other mills, it can save 30% ~ 50% energy and achieve ideal economic benefits.

Low cost input

Equipped with automatic control system, it can realize remote control and is easy to operate. PLC / DCS automatic control of grinding roller pressure control mode is adopted, and the grinding pressure is accurately controlled without manual operation. The grinding roller and the grinding plate are not in contact during operation, and the grinding roller and the lining plate are made of high-quality materials, with less wear and long service life. The grinding roller can be turned out to the outside of the casing for maintenance. It is convenient and fast to replace the roller sleeve and liner plate, reducing the loss of shutdown. The grinding roll lubrication adopts a separate lubrication station, and the single grinding roll circuit adopts the mode of double pump and pump suction working at the same time, which not only makes the grinding roll bearing fully lubricated and cooled, but also avoids excessive oil storage in the grinding roll bearing chamber and leakage.

CLUM Ultra Fine Vertical Mill Working Principle


The materials fall in the center of the grinding disc through the screw feeder, and the centrifugal force generated by the rotation of the grinding disc is driven by the reducer driven by the main motor, so that the materials move evenly around the grinding disc. When the materials pass through the roller table area on the grinding disc, they are crushed by the grinding rolls, and large materials are directly crushed. Smaller particles are extruded to form a material bed for inter particle crushing. After being crushed, the material continues to move to the edge of the grinding disc, and is brought into the powder concentrator by the air flow from the air inlet for classification. Under the action of the blades of the powder concentrator, the powder that does not meet the particle size requirements falls into the grinding disc for regrinding. The powder that meets the standard enters the pulse dust collector with the air flow through the powder concentrator for collection, and the collected and discharged powder is the finished powder. The impurities such as iron blocks mixed in the materials, which are difficult to grind and have high gravity, cannot be taken away by the air flow when passing through the edge of the grinding disc and fall into the lower chamber of the ultra fine vertical mill. They are sent to the slag discharge port by the scraping plate and discharged to the outside of the main machine.

Mention When Using Ultra Fine Vertical Mill

I-Pay attention to the position of commissioning personnel at all times. During operation, try not to be in the area where personnel are damaged by pipe swinging or high-pressure oil splashing due to hose and hard pipe breaking or falling off.

II-For the components mentioned in the system commissioning, please refer to the hydraulic schematic diagram, the general assembly drawing of the hydraulic station and the electrical schematic diagram.

III-Always pay attention to the display of the pressure gauge. In case of abnormal high pressure or repeated large fluctuations, please stop the machine immediately for inspection and treatment.

IV-Check whether the buttons and signals of the local electric control cabinet are normal at any time. If there are alarm signals such as motor overload, oil filter blockage, high oil temperature, and the button indication is inconsistent with the actuator action, please stop the machine immediately and check the cause (see the maintenance and repair instructions for the cause of the failure)

V-Check the liquid level of the oil tank at any time. If it is much lower than the reference line, stop the machine immediately to inject oil.
