HCH1395 heavy calcium(GCC) ultrafine mill is a new generation of large-scale high-efficiency heavy calcium(GCC) micro-powder grinding mill independently developed by HCMilling(Guilin Hongcheng). It draws on the working principle of the traditional ring roller mill and improves the shape, size and quantity matching of the grinding rollers. Without changing other parameters, the centrifugal grinding pressure is increased by nearly 30%, and the contact area between the grinding roller and the grinding ring is improved. , Improve the crushing efficiency, so that the output and fineness of the product have been greatly improved. The fineness of the product can reach between 0.008~0.038mm. At the same time, the overall casting base and the shock absorption foundation are used to make the operation of the equipment reliable. Higher performance, more convenient maintenance, and the use of pulse dust collectors for product collection, high collection efficiency and avoiding dust spillage. It is combined with high-precision classifiers, pulse dust collectors and other equipment to form a large-scale ultra-fine powder processing system, which has the characteristics of large output, high output per unit power, low comprehensive investment and operating costs, and high environmental performance. It can meet the national industrial policy and the expanding industrial scale production needs.

HCH1395 large heavy calcium(GCC) ultrafine ring roller mill is mainly composed of integral base, belt drive, central shaft, turntable, large and small grinding rollers, grinding ring, lubricating device, shock absorber, classifier and other components. The main pulley drives the turntable on the central axis to revolve in a circle, and the grinding roller installed on the turntable rotates around the central axis. There is a large movable gap between the grinding roller and the grinding roller pin, and the grinding roller swings horizontally outward under the action of centrifugal force. , so that the grinding roller presses the grinding ring, and the grinding roller rotates around the grinding roller pin at the same time. The material passes through the gap between the grinding roller and the grinding ring, and achieves pulverization and grinding due to the rolling of the grinding roller. The grinding roller is divided into multiple layers, and the material passes through the first layer of grinding roller and the grinding ring. Through multiple pulverization of multiple layers, the material is sufficiently pulverized and ground, and the obtained product has a fineness of fineness.

The special adaptability design of HCH1395 heavy calcium(GCC) ultrafine mill for heavy calcium(GCC) powder processing:

① Integral cast base, solid and reliable structure, strong anti-vibration ability, the biggest disadvantage of ring roller mill is the vibration and noise of the main engine, the use of the integral cast base can avoid the base or other components cracking or damage caused by the vibration fatigue of the main engine for a long time.

②The main engine is equipped with a shock-absorbing elastic foundation, which can effectively reduce the vibration generated during the operation of the main engine, and at the same time eliminate the resonance phenomenon caused by vibration with other peripheral equipment. Compared with the rigid foundation of the traditional ring roller mill, the noise and vibration of the main engine are reduced by 30%, which is greatly improved. It improves the stability of equipment operation, prolongs the service life of the mill, and improves the working environment of the workshop workers.

③The new type of transmission device, the main engine transmission device adopts the belt transmission device, the transmission is stable and reliable, and the maintenance is convenient and quick.

④The classifier adopts large-scale forced turbine classification technology, which has large processing capacity and high classification efficiency, which can make the particle size of the finished product adjust steplessly between 0.008 and 0.038mm. Large particle contamination ensures the stability of the qualified rate of finished products.

⑤Large specific surface area of finished product: Ultrafine powder with specific surface area of 22400cm2/g (d97=10μm)～30400cm2/g (d97=3μm) can be produced at one time.

⑥It adopts offline dust cleaning pulse dust collection system, which has the characteristics of large filter area, strong dust removal effect and long service life of filter bags. Moreover, after the separation of gas and powder in the dust collection system, the dust concentration of the discharged gas is less than or equal to 30mg/m³, which meets the national emission standard, which makes the grinding system more environmentally friendly.

⑦Combined with the working conditions of the ring roller mill, the wear parts of the wear parts are mostly extrusion, grinding and impact. The wear parts of the HC1395 large ring roller mill are made of wear resistant alloys. It is 30% longer than the small ring roller mill on the market.

⑧Optimize the equipment control system. The equipment control adopts the fully variable frequency PLC intelligent operation mode (multi-component linkage and one-key operation) mode. At the same time, the centralized remote control in mass production enables users to monitor the equipment operation in real time or on the spot.

In 2013, HCH1395 large-scale heavy calcium(GCC) ultrafine ring roller mill was tested in Guangxi Guilin Jinshan Chemical Co., Ltd. After testing, the output of a single HCH1395 large heavy calcium(GCC) ring roller mill is stable at 4.2.-4.5t/h. The average life of wear parts is 6000-6500 hours. Over the years, HCH1395 has been widely used in dozens of heavy calcium(GCC) processing enterprises at home and abroad. The operation effect of HCH1395 large-scale heavy calcium(GCC) ultrafine mill shows that the equipment has the advantages of high production capacity, high efficiency and good environmental protection performance, which can meet the needs of the increasingly large-scale industrial production of heavy calcium(GCC) micropowder industry.

(1) The production investment cost is low. On the premise of ensuring the same fineness, the production capacity of one HCH1395 large-scale heavy calcium(GCC) ultrafine mill is equivalent to more than two sets of 198 and 188 type ring roller mills that are currently widely used in the market, and the equipment occupies only 2/3 of that.

(2) High production efficiency, energy saving and environmental protection. HCH1395 heavy calcium(GCC) ultrafine mill system can reduce unit product energy and equipment consumption by 25%-40% compared with other similar equipment (vertical roller mill, ball mill).
