1. Introduction Of HC Calcium Hydroxide / Calcium Oxide Specialized Superfine Vertical Grinding Mill

Drawing on the technology of Germany, Japan and Taiwan, HCM HC calcium hydroxide/calcium oxide specialized ultra-fine vertical grinding mill is a large-scale vertical grinding equipment developed independently by HCM. Capable of producing powder ranging from 325-2500 mesh, it has made breakthrough in ultra-fine powder production capacity, emerging as an ideal ultra-fine powder equipment for chemical production.

The wear-resistant parts of HC calcium hydroxide / calcium oxide specialized ultrafine vertical grinding mill mainly encompasses grinding roller, grinding table, classifier, grinding lining, chute, pipeline and other parts. Low alloy steel surface composite high CrMoV wear-resistant alloy is used for the grinding tire and table, which can enhance the wear-resistance, impact resistance and comprehensive wear-resistant ability, the reuse rate, as well as efficiency while lowering the cost.

 

2. Introduction Of HCQ Series Calcium Hydroxide Slaking System

HCQ Series Grinding Mill is a newly designed and developed mill, with more advanced technology than R-Series Pendulum Roller Mill. HCQ Series Grinding Mill has more scientific and reasonable configuration on main mill, classifier, blower, pipe system and feeder, all these largely increase the overall performance of the facility.

1). Industrial Calcium Hydroxide Production

With the power consumption for the production of calcium hydroxide standing 18-23kw/ton, HCQ slaking system stands out among its peers in terms of power efficiency. (subject to the difference of the effective calcium oxide content).

2).Quality Standard

HGT4120-2009 Industrial Calcium Hydroxide Standard

Standard for Coating Ash Calcium Powder-001-2016

3). Raw Material Selection

Metallurgical lime is not recommended for deep processing. Lime powder and other deep processing lime used must meet the deep processing standards to produce calcium hydroxide. It is advised that more than 90% effective calcium oxide be selected to produce calcium hydroxide. The higher the whiteness of the lime the better to produce ash calcium powder.

2. HCQ Series Grinding Mill Structure (HCQ Slaker)

HCQ Series Grinding Mill consists of main mill, classifier, pipe system, blower, cyclone collector, base, central shaft support, ring, spider-arm, roller assembly, shaft, lifter support, lifter support base, electromagnetic-vibrating feeder and electronic control system. The ring and roller are made from wear-resistant material, whose surface is also given wear-resistant treatment. For the driving system, there are reducer and double-motor system for option. The classifying system uses the turbine classifier. Various feeding and conveying system can be done separately according to different material. The close system with cyclone plus pulse-jet collector and the open system with only pulse-jet collector are available for collecting system. As to the control system, you can select auto control or remote control. 

1). Watering System: Smart water distribution system


2). Slag Discharging: Slag can be discharged after slaking to improve the purity of calcium hydroxide


3). Dedusting: Pulse filtering bag paired with water dedusting, the dedusting efficiency is higher.


4). Pre-slaking: The pre-slaking system is made of wear-resistant alloy, enjoying longer service life.


5). Slaking System: Slaking at constant temperature, small floor area occupied, sufficient time, sufficient slaking


6). Automation: PLC full automatic control, enhanced quality control ability


7). Hot water Slaking: Speedy hot water slaking accelerates slaking

1. HC Calcium Hydroxide / Calcium Oxide Specialized Superfine Vertical Grinding Mill

1). High Grinding And Classifying Efficiency: The mill employs the material bed grinding theory, making material reside in the mill for a shorter time, which leads to easy detection of the particle size distribution and composition of the product, less repeated grinding, lower iron content, high whiteness and purity of the finished product; The finished product is uniformly shaped and enjoys narrow particle size distribution, good fluidity, and strong adaptability

 

2). Environment-friendliness: The whole system enjoys small vibration and low noise; The whole system is sealed, operated under full negative pressure without dust spillover, which basically results in dust free workshop.

 

3). Small Investment : It has integrated crushing, drying, grinding, grading and conveying. with simple process, streamlined system, compact layout, small floor area required, only 50% of the

ball mill, the production line can be set up in the open air, which requires lower construction cost and smaller investment.

 

4). Easy Maintenance And Low Operation Cost: The grinding roller can be pulled out of the machine by hydraulic device, which makes the replacement of roller tire liner easier and the maintenance space of the mill larger; The grinding roller tire can be flipped over for use, which prolongs the service life of wear-resistant materials; The mill can be started without material inside, which makes starting the machine easier; The grinding roller and the grinding plate liner are made of special material, which reduces the wear-tear and prolongs service life.

 

5). High Reliability: Limit device is employed for grinding roller to avoid the violent vibration caused by direct contact with grinding table. The new sealing device of grinding roller is adopted, which is reliable and saves the need of sealing fan while the oxygen content in the grinding chamber is reduced, which makes the mill highly explosion-proof. 

 

6). High Level Automation: PLC automatic control system, remote control, simple operation, easy maintenance, low labor cost.

 

7). Product Quality Is Stable And Excellent: Grinding curve of roller tire and liner plate for superfine powder grinding is specially designed, which makes material to easily form the layer and leads to high grinding efficiency and high yield of one-time grinding; With the output as high as up to 40t/h, its production capacity per unit is large, which is equivalent to more than 5 sets of superfine powder grinding combined while low-voltage power can be used; Single and multi classifier is alternatively used to adjust the fineness of the finished products within the regulated range without the need of secondary classifier. In the production of products with the same fineness level, it consumes 30% - 50% less power than that of ordinary mills.
