How Much Is A Kaolin Grinding Mill?| Kaolin Grinding Mill Manufacturer

In recent years, my country's kaolin resource exploration has achieved remarkable results. In 2020, my country's proven kaolin reserves reached 5.72 billion tons, a year-on-year increase of 61.6%. The pulverizer is an indispensable processing equipment for the application of kaolin in the downstream, so what kind of pulverizer is suitable for grinding kaolin? How much is a kaolin grinding mill?

What is Kaolin?

Kaolin is a kind of clay and clay rock mainly composed of kaolinite clay minerals. Because it is white and delicate, it is also called dolomite or Guanyin soil. It is named after Gaoling Village, Jingde Town, Jiangxi Province. The pure kaolin is white. Delicate, soft soil-like, the main components are alumina and silica, density 2.54-2.60g/cm3, hardness 3-4, sometimes up to 5-6, with plasticity, adhesion, adsorption, suspension, sintering And fire resistance, firing shrinkage, good insulation and chemical stability.

Application of kaolin

Kaolin can be used in papermaking, ceramics, enamel, coatings, refractories, cement, plastics, rubber, petroleum, chemical industry, medicine, light industry, agriculture and other industries. The two main application fields are:

(1) Ceramics is the industry with the earliest application of kaolin and a large amount. The general dosage is 20-30% of the formula. The role of Al2O3 in ceramics is to introduce Al2O3, which is conducive to the formation of mullite, improve its chemical stability and sintering strength, and give good formability to porcelain clay and glaze, which is convenient for forming.

Whiteness is one of the main parameters of kaolin process performance, which can be divided into natural whiteness and calcined whiteness. The higher the calcined whiteness, the better the quality. Ceramic process stipulates that drying 105 ℃ is the classification standard of natural whiteness, calcining 1300 ℃ is the classification standard of calcined whiteness, and the fineness is 45 microns d99-99.97.

(2) In the paint and coating industry, kaolin is mainly used to replace white pigments, especially titanium dioxide. Kaolin with different particle sizes and types is used in different types of paints, coarse kaolin is used in paints that need dim gloss or flat gloss, fine kaolin is used in paints that produce high gloss, or in the manufacture of latex pigments, which can make the coating have better opacity, simultaneity and anti sedimentation, and improve the hardness of the film, Warning film quality.

Paint and coating is the largest consumption field of calcined kaolin in China, accounting for about 65-85% of the total consumption. High quality calcined kaolin with whiteness of more than 90 and fineness of more than 1250 mesh is widely used in special functions such as interior and exterior wall coatings, anti-corrosion coatings, grinding coatings, heat-resistant coatings, insulation coatings, road sign coatings, waterproof coatings, anti radiation coatings, etc.

What kind of pulverizer is good for kaolin? HLM kaolin vertical roller mill equipment produced by HCMilling(Guilin HongCheng) has the following advantages:

1. Lower energy consumption, such as hlm2400 processing raw kaolin, 325 mesh d95, with a capacity of 30t / h

2. The moisture content of the finished product is lower, and the moisture content of the finished product can be controlled below 0.3%

3. The installed area is smaller, and the building station structure is adopted, which saves about 40% compared with the installed area of equipment in the same industry;

4. The degree of automation is higher. Compared with the equipment in the same industry, the whole series adopts PLC control, and the sampling sensors are designed for humidity, transmission speed, air pressure, hydraulic pressure, vibration, amplitude, etc. the reliability, integration and ease of operation are guaranteed.

5. The after-sales service is more guaranteed. Compared with the equipment in the same industry, the company has more than 100 R & D technicians and more than 40 after-sales personnel, with high collaboration efficiency, high standardization of equipment components, good substitutability, and large processing capacity of components.

In addition, the maximum capacity of a single HLM kaolin vertical roller mill of HCMilling(Guilin HongCheng) can reach 200t/h, and the grinding fineness is 22-180μm. Large production capacity is more environmentally friendly. Equipment prices range from hundreds of thousands to millions of yuan. If you have purchased equipment or consulted the pulverizer equipment, you know that regular and reliable manufacturers will not directly give you a quotation. Usually, they will make reasonable selection and configuration according to your production capacity and the fineness of finished products.

Different manufacturers will also have different prices due to the use of raw materials, equipment technology, manufacturer strength and other factors. If you want to know the specific equipment quotation, please contact mkt@hcmilling.com or call at +86-773-3568321, HCM will tailor for you the most suitable grinding mill program based on your needs, more details please check www.hcmilling.com.
