1. Generalized grinding The generalized grinding produced by Hunan Generalized Technology Co., Ltd. (hereinafter referred to as Generalized Technology) is a vertical structure consisting of a transmission device, a grinding device and a machine body. During operation, the transmission rotates the main shaft to drive the rotor parts such as the grinding roller to rotate synchronously; after the material enters from the upper feeding port, the spreading disc is evenly scattered to the inner wall of the wear-resistant lining, and the grinding roller acts on friction and material resistance. Turn and roll the material down. The material that has been repeatedly crushed into a powder is discharged from the discharge port located at the lower portion. The main technical parameters are listed in Table 1.
GY type generalized grinding: the grinding roller and the lining plate are kept at an adjustable interval. The grinding force is derived from the combined force of centrifugal force and spring force. The wearing parts have long service life, low noise and large processing capacity, and are suitable for grinding various soft and hard materials.
GL type generalized grinding: multi-stage grinding, uniform grinding particle size, single machine grinding particle size up to 80 mesh or more, grinding power from centrifugal force field, suitable for softer materials.
Generalized GM type mill: GL or a GY generalized mill grinding devices and other components and protection systems, mainly used for grinding a variety of flammable, explosive and other special materials, such as: electrolytic metal manganese, sulfur, aluminum and magnesium alloy.
The characteristics of generalized grinding are: 1 low power consumption, only 40%~60% of ball mill or Raymond mill ; 2 long life of wearing parts, only one hundred thousandth of material iron ; 3 no dust and noise pollution, finished product The rate is high, the system operates under normal pressure closed circuit, the recovery rate is almost 100%; 4 small volume, the floor space is only 1/2 of the ball mill, 2/3 of the Raymond machine; 5 can be flammable and explosive And soft material and other special materials; 6 simple structure, easy maintenance.
Generalized grinding can be opened in a single machine, suitable for occasions where the product size is not strict. The discharge size is generally -20 mesh or -80 mesh. It can be combined with cement mill to form a closed circuit for pre-grinding, which can increase the output of the mill and reduce the unit power consumption. It can also form a loop system with the classifier and conveyor, and the product fineness can reach 80~400 mesh. The matching classifiers include the GXL series high-efficiency centrifugal classifier and the KX series high-efficiency rotor classifier, and the bucket elevator is used as the vertical conveying device.
Generalized grinding is widely used in the building materials, metallurgy, chemical, mining, energy, refractory materials and other industries in the Mohs hardness of 8 or less, the fineness of the finished product is not higher than -400 mesh, such as: cement (raw Materials), limestone , lime, fly ash, gypsum , glass, sandstone , coal , coking coal, shale , coal gangue, serpentine, slag, blast furnace slag, talc , calcite , dolomite, marble, fluorite , granite , wollastonite, etc.
2. Global Milling Machine Global Mill is a research project of the Ministry of Mechanical Engineering of the Wuhuan Mine. After 10 years of research and industrial experiments, it is mainly used in chemical industry, building materials, metallurgy, refractory materials, abrasives and many more. Processing of fine powders and fine powders of non-metallic minerals. In particular, the processing of materials with hardness between 6 and 9 and humidity <5% or less, such as corundum , silicon carbide, spinel, dolomite, barite , high alumina, etc., is more effective. The technical parameters of the global mill are shown in Table 2.
Its main features are: 1 long service life of wear parts, extremely small amount of iron in processing materials, 1/4 of other conventional equipment such as Raymond machine and ball mill; 2 product fineness can be adjusted between 100~500 mesh 3, reliable operation, failure rate is lower than ball mill, Raymond machine; 4 fully enclosed loop, dust pollution is small.
3.HQM-820 hydraulic powerful grinding machine HQM-820 hydraulic powerful grinding machine is a new type of grinding powder developed by Hongye Machinery Co., Ltd. (hereinafter referred to as Gongyi Hongbo) of Gongyi City, Henan Province. The equipment is a replacement product of Raymond mill, air sorter and ball mill.
The grinding machine adopts hydraulic strength adjustment, and has an upper grinding disc, a ball rolling grinding, an electromagnetic feeding, and a ring wind classification to form a powder. The deceleration and transmission systems all use automotive-specific gears.
The mill has small volume, compact structure, labor saving, power saving, high efficiency, no pollution, low noise, convenient operation, simple maintenance and strong adaptability.
The main technical parameters of HQM-820 hydraulic powerful ultra-fine grinding machine are listed in Table 3. It is suitable for grinding ultra-fine powder, powder processing and deep processing in chemical, building materials, metallurgy, refractory materials, abrasives, high-efficiency cement and other industries. Especially for non-metallic materials with Mohs hardness between 6 and 9 and humidity below 696 (such as white corundum, brown corundum, silicon carbide, spinel, dolomite, silica , calcite, barite, high alumina The processing of soil, etc. is more effective.
4. Fan coal mill fan coal mill is used to grind coal. The technical parameters are listed in Table 4.
