Chemical properties and uses of ceramic soil powder

The main chemical component of ceramic soil is barium sulfate, which belongs to sulfate minerals and is a very important non-metallic mineral raw material. Its chemical properties are stable, it is insoluble in water and hydrochloric acid, non-magnetic and toxic. Barium sulphate used in the industry often contains impurities and is dyed in various colors. Due to the chemical nature of its two series, it has a wide range of uses in the industry.

Ceramic soil powder can be used as mud weighting agent

The ceramic soil can be used as a mud weighting agent after being processed by raymond grinding mill. For example, when drilling in two oil wells or gas wells, the pressure of underground oil or gas tends to be higher, and the ordinary mud has a lower specific gravity, which is offset by the pressure of the mud alone. This part of the pressure is very prone to blowout accidents. The correct way is to use ceramic clay to mix the muddy clay and increase the proportion of the mud. This measure can effectively balance the pressure of underground oil or gas and greatly reduce the occurrence of blowout accidents.

The study found that ceramic micro-powder can be used as a weighting agent and mixed into the mud. It is necessary to use equipment to finely grind the ceramic soil to a suitable size, which can be mixed into the mud to increase the specific gravity of the mud. Therefore, the processing of ceramic soil requires a suitable mill. The raymond mill for ceramic soil processing can grind ceramic soil to a suitable size, and the special ceramic soil processing equipment is easy to operate and has high processing efficiency, which can effectively enhance the competitiveness of the manufacturer and obtain more profits.

After the ceramic powder is micro-powder and processed, it can be used as a zinc enamel white pigment.

It can be seen from the chemical properties of ceramic soil that the main component of ceramic soil is barium sulfate. After the ceramic soil is ground into a ceramic soil powder by a raymond mill, the barium sulfate is heated, and the barium sulfate can be reduced to barium sulfide by using a reducing agent, and then mixed with zinc sulfate to obtain a mixture of barium sulfate and zinc sulfide. This becomes a zinc antimony pigment. Zinc antimony pigment is a commonly used high quality white pigment that can be used as a raw material for paints or paintings. For the purpose of these two uses of ceramic soil, our factory designs the raymond mill for ceramic soil processing, which is very simple in operation, can directly make the ceramic soil micro-powder into a suitable size, and can provide great convenience for the production of barium sulfate liquid.

There are many uses of ceramic soil micro-powder. The engineers of Guilin Mining Machinery Co., Ltd. went deep into the second line of the micro-powder industry, and communicated with many users of raymond mills and technicians of the micro-powder industry, aiming to design a suitable raymond mills such as mills are more professional and efficient, relatively simple to operate, and relatively low cost micro-powder industry tools.

The micro powder grinder mill is a highly efficient flour milling equipment, which was made on the basis of high-pressure powder mill and was improved by fineness classification technology. The advanced fineness classification technology of Germany and Japan adopts the principle of fluid mechanics. Scientists studied diligently with a quiet mind, and then they designed a new micro powder mill. So they solve the problem of high cost successfully. It is a high-efficiency and high-pressure micro powder mill.

The Application Scopes of Micro Powder Mill

The micro powder mill is mainly suitable for grinding of conventional materials and the ultra-fine powder processing of non inflammable and non explosive materials, such as kaolin, limestone, calcite, talcum, marble, barite, gypsum, iron oxide red, iron oxide green, aluminum hydroxide, pigment, bentonite, clay, coal, activated carbon and so on, the humidity of which is less than 8%, and the Moh's hardness of which is less than level 6.

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 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.

The grinding device adopts overlapping type multiple stage seal and has good sealing performance.

The dust removal effect of the mill can totally reach the national dust emission standard.

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.
