Silicon carbide is made by quartz sand, petroleum coke and high-quality silica as the main raw materials. Guilin Mining Machinery's pendulum grinding mill, which combines high efficiency, high productivity and environmental protection, can guarantee the manufacture of silicon carbide.

Abrasive

Mainly because silicon carbide has high hardness, chemical stability and certain toughness, silicon carbide can be used in the manufacture of bonded abrasives, coated abrasives and free grinding to process glass, ceramics, stone, cast iron and Some non-ferrous metals, hard alloys, titanium alloys, high speed steel tools and grinding wheels.

2. Refractory materials and corrosion resistant materials

Mainly because silicon carbide has high melting point (decomposition degree), chemical inertness and thermal shock resistance, silicon carbide can be used in slabs for grinding tools, ceramic products, and kiln and zinc smelting industrial vertical cylinders and a variety of silicon carbide ceramic products such as silicon carbide bricks for distillation furnaces, aluminum electrolytic cell linings, crucibles, and small furnace materials.

3. Chemical industry

Because silicon carbide can be decomposed in molten steel and reacted with oxygen and metal oxides in molten steel to form carbon monoxide and silicon-containing slag. Therefore, it can be used as a purifying agent for smelting steel, that is, as a deoxidizer for steel making and a modifier for cast iron. This generally uses low purity silicon carbide to reduce costs. At the same time, it can also be used as a raw material for manufacturing silicon tetrachloride.

4. Electrician

It is used as a heating element, a non-linear resistance element and a high semiconductor material. The heating element refers to a silicon carbon rod (suitable for various electric furnaces operating at 1100 to 1500 ° C), a non-linear resistance element, and various types of lightning protection valve sheets.

5. Other

It is formulated into a far-infrared radiation coating or a far-infrared radiation dryer made of silicon carbide silicon plate.

The advantages of using a new environmentally-friendly pendulum grinding mill for the manufacture of silicon carbide:
First, the most popular models
With the pendulum grinding structure, the material is processed more efficiently and with higher efficiency in the unit grinding time.

Second, cost-effective

The output of a single unit is up to 25 tons / hour, and the output of the equipment is equivalent to 6 conventional 4R mills. The power consumption is low, and the power consumption is about 3/4 of 6 4R Raymond mills. The successful development of the HC1700 is the first revolution in the expansion of the Raymond grinding mill.

Third, high efficiency and high yield

1. Multi-layer barrier structure to ensure the sealing of the grinding roller device
   The working environment of the roller device is extremely high dust concentration. The roller device of the conventional R-type pendulum mill cannot reliably seal the bearing by the laminated seal. The grinding roller assembly needs to be refueled every day. The HCZ vertical pendulum mill adopts maintenance-free oil seal technology, spiral seal and skeleton oil seal multi-layer barrier structure to effectively prevent the entry of dust and maintain the normal working state of the roller assembly. It takes only 500-800 hours to refuel and maintain once, greatly reducing equipment maintenance time.
   
   2. The mill adopts frequency conversion speed control and adopts PLC interface operation, which can basically realize fully automated production. The workshop can realize unmanned operation and greatly save labor cost. And customers can choose the remote intelligent monitoring system of the mill, and control the operation of the mill all the time.
   
   3. The important parts are made of thick high-quality steel, and the wear parts are made of high-performance wear-resistant materials. The whole machine has high wear resistance and long service life.

Fourth, easy to maintain

From the crushing, conveying and milling of raw materials to the collection, storage and packaging of finished products, it can be an independent and complete production system with strong systemicity. The applicability of the equipment is strong, and it is not necessary to replace any parts to meet the needs of producing different materials and different fineness products.

The Structure of Raymond Mill

The structure of Raymond mill is mainly composed of the main engine, analyzer, fan, cyclone separator, cyclone separator and air duct. The main engine is composed of frame, intake volute, blade, grinding roller, grinding ring and cover.

The grinding roller is tightly pressed on the grinding ring under the action of centrifugal force. Therefore, when the grinding roller and grinding ring wear to a certain thickness, the output, and fineness of the finished product will not be affected. The replacement cycle of grinding roller and grinding ring is long so that the disadvantage of short replacement period of wearing parts of centrifugal grinder can be eliminated. The air flow of the machine is circulating in the fan - mill - whirlwind separator - the fan, so it has less dust than the high-speed centrifugal mill has, the operation workshop is cleaner and the environment is less polluted.

Performance Advantages of the Raymond Mill

3. Fineness can be adjusted arbitrarily

The fineness of the grinding powder of Raymond mill can be adjusted arbitrarily between 80-800 mesh. The applicability is more flexible and extensive. We can see that the GUIKUANG Raymond mill is the best choice for non-metallic ore grinding powder.

4. Long Period Replacement of the Parts

The grinding roller and grinding ring of Raymond mill have a longer replacement period, which eliminates the disadvantages of the short replacement period of the fragile parts of the centrifugal grinder

The Operation principle of Raymond Mill

When Raymond mill works, the material needs to be added to the feeder from the side of the hood. Raymond machine revolves around the vertical axis by means of the grinding roller device which is hung on the main plum frame. At the same time, it revolves on its own axis. Due to the centrifugal force when rotating, the grinding roller is swinging outwards and tightly pressed to the grinding ring. This enables the scraper to shovel the material to the grinding roller and the grinding ring. Therefore, it can achieve the purpose of crushing material due to the rolling of the roller.

The Winnowing Selection Process of Raymond Mill

After the materials being grinned, the fan blows the wind into the main engine shell, blowing up the powder, sorting through the analyzer above the grinding room, passing the rough materials into the grinding room and then regrinding it. The suitable fineness materials go into the cyclone collector by the wind. After collection of these materials, the finished products will be discharged through the powder mouth. The air flow from the upper end of the large cyclone collector will return to the fan. The winding road is cyclic and flowing in the negative pressure. The increasing part of the air volume of the cyclic air road is discharged by the exhaust pipe between the fan and the main engine, then this part enters the small cyclone collector to carry out purification treatment.

The Structure Characteristics of Micro Powder Mill

The high-pressure micro powder mill mainly consists of the main engine, blower, superfine analyzer, finished cyclone powder collector, bag filter and connecting duct. According to user needs, it can provide with auxiliary equipment such as the hoist, storage bin, electric cabinet, feeder, crusher and so on. In the grinding mill room, the grinding roller assembly is hung on the grinding cradle through the cross arm shaft. The grinding cradle, spindle and the relieving tool post are fixed. The pressure spring is tightly pressed on the outer end of the cantilever housing of the grinding roller bearing chamber by a tension rod. Taking the transverse load axis as the supporting point, the grinding roller is firmly pressed on the inner surface of the grinding ring by the spring pressure.

When the motor is rotated through the drive, the blade of the blade is synchronized with the grinding roller, and the roller rolls around the surface of the grinding ring and rotates around itself. The analysis machine drives the rotating of the impeller through the motor drive. The speed adjustment of the analysis machine determines the fineness of the powder. The relieving tool in the relieving tool post and the grinding roller rotate at the same time. Then the grinding roller rotates on the inner surface of the grinding ring and revolves around itself. The analysis machine drives the impeller of the analysis machine through the motor drive device, and the speed adjustment of the analyzer determines the fineness of the powder.

The Main Features of Micro Powder Grinder Mill

The application scope of the high-pressure powder mill is much larger than that of the airflow mill.

Compared with other mills, the grinding pressure of grinding roller on the material can provide 800---1200Kg under the action of high-pressure spring. It saves energy. Under the same circumstance of output and fineness, the energy consumption of the system is only 1/3 of that of the airflow mill.

The investment is small and the efficiency is high. Under the same circumstance of output and fineness, the price is only 1/8 of the airflow mill.

Compared with the air mill, the production link is less. Firstly the airflow mill must crush the material of 20mm to the superfine powder of 100 mesh, and the high-pressure micro powder mill can make the material reached the average particle size about 6.5 μm to 12.5 μm for one time, of which the size is below the 20mm.
