HLM series advanced coal vertical mill is an energy-saving advanced grinding equipment that integrates drying, grinding, grading, and conveying, which is developed by Guilin Hongcheng through learning and introducing advanced foreign technology and after more than 20 years of painstaking research and development. Guilin Hongcheng HLM customized coal vertical mill has the advantages of high grinding efficiency, low power consumption, large feed particle size, easy adjustment of product fineness, simple equipment process flow, small footprint, low noise, low dust, easy use and maintenance, Advantages of low operating cost and low consumption of wear-resistant materials. It can be applied to the grinding of limestone.

 

The HLM vertical mill can grind materials with a water content of 20% to 30% to a water content of less than 1%, and is highly adaptable to materials. The product fineness can be adjusted from 2-5mm to 15μm with a pass rate of 97%.


Main machine section structure

The HLM vertical mill adopts a standard modular design to manufacture a pressurizing device. As the capacity of the mill increases, the number of grinding rollers is correspondingly increased (2, 3, 4 or 6 grinding rollers can be used), and the arrangement is combined to compare Few standard module parts, forming a series of products with multiple capabilities, meeting the requirements of different material processing and different product fineness and output.

ADVANTAGES AND FEATURES                                                                                                                                                                                                                        


image.png1. Low overall investment cost

It integrates crushing, drying, grinding, grading, and conveying. The process flow is simple, the system equipment is small, the structure is compact, and the area is small, which is 50% of the ball mill. It can be laid out in the open air and the construction cost is low, which directly reduces the investment of the enterprise cost.



image.png2. High grinding efficiency

The grinding efficiency is high and the energy consumption is low. Compared with the ball mill, the energy consumption is 40%-50% lower; the single machine has a large production capacity and can use low power.



image.png3. Convenient maintenance and low operating cost

The grinding roller can be turned out of the machine with a hydraulic device. The replacement of the roller sleeve liner and the grinding machine have a large maintenance space, and the maintenance operation is very convenient, the grinding roller sleeve can be turned over and used, which extends the service life of wear-resistant materials. The mill can be started without load, eliminating the trouble of starting. 


image.png4. Stable product quality

The material stays in the mill for a short time, which is easy to detect the particle size distribution and chemical composition of the product, reduces repeated grinding, and the product quality is stable, the product has uniform particle shape, narrow particle size distribution, good fluidity, and strong product adaptability. The iron content is very small, and the mechanically worn iron contained is easy to remove. When used for grinding white or transparent materials, the product has high whiteness and purity.


image.png5. High reliability

The roller limit device is used to avoid the severe vibration caused by the material interruption during the working hours of the mill. The use of a new type of grinding roller sealing device, reliable sealing, and no need to seal the fan, further reduce the oxygen content in the mill, and excellent explosion suppression performance.



image.png6. Environmental protection

The whole system of HLM vertical mill has low vibration and low noise. The whole system is sealed and operated under negative pressure, and there is no dust spillage. It can basically realize a dust-free workshop. Vertical mill technology and equipment are new technologies for energy saving and consumption reduction, which are beneficial to improve the company’s powder Competitive strength in the industry.


image.png7. High degree of automation

Adopt PLC automatic control system, and can realize remote control, simple operation, convenient maintenance, and reduce labor cost.




image.png8. Strong drying capacity

Because the vertical mill can directly pass hot air, the hot air directly contacts the material in the mill, the drying capacity is strong, and the incoming material moisture is high, which can reach 15%. The vertical mill powder system does not need to be equipped with an additional dryer, saving equipment investment costs and energy consumption costs. By adjusting the temperature of the hot air, materials with different humidity can be dried and grinded at the same time.

HLM long flame coal grinding mill is mainly composed of main machine, feeder, classifier, blower, pipeline device, storage hopper, electric control system, collection system, etc.

WORKING PRINCIPLE                                                                                                                                                                                                                                       


The motor drives the reducer to drive the grinding disc to rotate, and the material to be ground is fed into the center of the rotating grinding disc by the lock 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 the roller pressure, the material is crushed by squeezing, grinding and shearing.

COAL POWDER PRODUCTION PROCESS                                                                                                                                                                                                      


1. Crushing of raw materials

Large pieces of long flame coal are crushed by the crusher to the fineness (15mm-50mm) that can enter the mill.

 

2. Drying and grinding

A. The crushed coal material with relatively low moisture content is sent to the storage hopper by the elevator, and then sent to the grinding chamber of the mill evenly and quantitatively by the feeder for grinding. The mill is treated with hot air to achieve drying in the mill and save drying costs.

B. For materials with high moisture content, use a dryer to dry the coal in the front part of the mill, and the dried raw materials are then milled for grinding.

 

3. Classification

The ground material is classified by the classification system, and the unqualified powder is classified by the classifier and returned to the main engine for re-grinding.

 

4.Collect finished products

The powder that meets the fineness is separated and collected by the airflow through the pipe into the dust collector. The collected product powder is sent to the finished product silo through the discharge port by the conveying device, and then is packaged by a powder tanker or an automatic baler.
