Kaolin is one of the industrial minerals that can be found in commercial quantity. In fact, Nigeria has an estimated reserve of about two billion metric tones of kaolin deposit scattered in different parts of Nigeria including Ogun, Edo, Plateau and Nassarrawa states. The market for kaolin is very expand, sustainable and expanding becaused of the numerous applications of the product. Also there is an outright ban on the importation of kaolin into the country in order to stimulate the growth of the local industry.
Kaolin processing can be operated in two ways, the wet and dry process. The wet process is used when the silica content and impurities in the raw kaolin is high and usually the end product is high grade kaolin used in the pharmaceutical industry. The dry process involves several different stages, including drying, crushing, sifting and bagging of the raw kaolin and it is usually employed for raw kaolin with less silica and impurity content.
The dry process is simpler and produces a lower quality product than the wet process. Dry processed kaolin is used mainly in the rubber industry, and to a lesser extent, for paper filling and to produce fiberglass and sanitary ware. Wet-processed kaolin is used extensively in the paper manufacturing industry.
Most kaolin mineral is mined by open-pit methods using various types of equipment. The extracted kaolin usually is conveyed to the processing plants. For most applications, kaolin is processed by mechanical methods, such as crushing, grinding, screening, and sizing. However, because kaolin are used in such a wide range of applications, it is often necessary to use other mechanical and chemical processes, such as drying and calcining to prepare the material for use.
SBM is global supplier and manufacturer of kaolin processing plant. Based on professional experience, we developed complete range of kaolin processing machinery for sale including quarrying machine, crushing plant, grinding machine, screening machine, belt conveyor, separation equipment etc. Our kaolin processing plant machinery prices are competitive compared with other similar machine.
Kaolin wet pulverizing process is much more complex than dry processing. The kaolin is dispersed in water after it is mined. The first step after dispersion is the removal of the coarse grit by setting procedures and vibrating screens.The resultant degritted slurry is fed into centrifuges to separate the kaolin into fine, intermediate, and coarse particle size fractions. The kaolin is then dewatered through a filtration process, dried in either rotary, apron ore spray driers, and prepared for final application.
SBM experts have been dedicated in crushing and grinding technology for several decades. With know-how technology, we provide cutting-edge grinding solution according to customers' requirements. We provide comprehensive series of kaolin grinding mill for kaolin powder processing including ball mill, raymond mill, high pressure mill, vertical mill, coarse powder mill, trapezium mill, ultrafine mill, hammer mill etc.

Due to its unique features of ultrafine end products and high grinding efficiency, SBM ultrafine mill has widely applications in powder processing and has been greatly welcomed in the world market. We could provide cutting-edge crushing and grinding solution for mining industry. If you are interested, please chat online with us for more information.
Most kaolin is the dense state or loose soil materials. It is easy to disperse in water or other liquid. Kaolin has a soapy, earthy and the density is 2.54-2.60 g/cm3. Kaolin has strong plasticity and the wet clay can be shaped into various shapes which can remain unchanged for a long time.
Pure kaolin has high white degree and it is soft. Besides, this kaolin has the following characteristics: excellent electrical insulating performance, good resistance to acid soluble, lowexchange capacity and good fire resistance. Therefore, kaolin is the necessary raw material for paper-making, ceramics, rubber, chemical industry, paint, medicine and defense of mineral.
Kaolin grinding milling production line belongs to the secondary main processing stage. The kaolin raw materials will be crushed and then is the grinding line. In kaolin grinding production line, the crushed kaolin materials can be broken into fine powder to satisfy clients' production needs.
Kaolin grinding milling plant can produce various kaolin raw materials into powder for further applications. When you choose the kaolin grinding mill machine, SBM professional engineers suggest the following machine for you: ball mill, Raymond mill, MTM medium speed trapezium mill, ultrafine mill towards the customers for grinding kaolin particles into fine powder.
Kaolin rocks will be grinded into small size or even the powder size for further application. In this milling stage, it will need the grinding milling plant machine to help customers to realize. SBM's advanced and high quality milling machine is the better choice for your production line.
Different kinds of milling machine have different output size and the grinding efficiency. According to the detailed kaolin raw material characteristics in different areas, SBM will design the specific grinding milling machine for our clients. Choosing the suitable kaolin grinding machine will help you get high profits. Here will introduce two kinds of kaolin grinding mill machine for you all: ball mill and SCM ultrafine mill.
SBM ball mill is widely used in various application areas. It can produce a consistent and highly reliable product within a closed circuit. Because of the high grinding ratio, wet or dry grinding methods, the ball mill machine can meet the production requirements. SBM ball mill can grind the kaolin into powder down to 0.074~0.4 mm. It may be the most cost-effective and practical kaolin grinding milling with high producing capacity.
SCM ultrafine mill is usually a kind ultrafine pulverizer, the final powder size could be down to 325~2500 mesh. It uses a combination of size reduction mechanisms, including impact, attrition and particle-particle collision, to achieve much smaller particle sizes than other mills. In addition, the mill has an easily adjustable grinding gap, which allows you to produce particle sizes from ultrafine to coarse. This eliminates the need for other types of grinding equipment and enables you to easily vary particle size and production rates, improving your overall flexibility and efficiency.
In kaolin grinding plant, besides the main grinding machine, it also needs the auxiliary equipment to help finish the whole production. The common auxiliary equipment has vibrating feeder, vibrating screen and belt conveyor. SBM vibrating feeder is used to feed kaolin raw materials into grinding machine to be processed. The belt conveyor will take kaolin materials from one milling machine to another. Vibrating screen will separate the coarse grinded kaolin materials to be processed again.
