 (2) Process and equipment
Ore chopped pulp dispersion, sieving, hydrocyclone desander, obtain - 20 μ m products, and then by centrifugal classification, stripping, bleaching, washing, and concentrated to remove fine particles smaller than 0.2 μ m, followed by filtration, drying, milling , obtaining a knife coating grade and a filler grade kaolin powder product.
In order to ensure product quality, the yield of coating grade products is improved. New technologies such as stripping and centrifugation are used in the process. Advanced equipment such as stripping machine, horizontal spiral centrifugal classifier, nozzle chip centrifuge, drum roller discharge vacuum filter and spray dryer have been introduced from abroad. The main beneficiation plant process equipment in Table 13.
(3) Technical and economic indicators
Due to the lack of normal production , the technical and economic indicators for design are listed in Table 14 . The quality of the pilot products is listed in Table 15 .
The air-conditioning fan is a brand-new concept fan, which has the functions of air supply, cooling, heating, air purification, and humidification. Compared with electric fans, air conditioning fans have the function of humidifying air, but their power is much higher than that of traditional fans, about 60-80W, but much lower than that of air conditioners. The price is very friendly. However, after all, it cannot be cooled by itself, and it needs to continuously inject water of the required temperature to continuously provide the wind of the required temperature, so it is quite inconvenient to use. Water can continuously provide cold air for about half an hour. After half an hour, the water temperature in the body is assimilated by room temperature, so be careful not to add too much water at one time, but a small amount several times. (Note: If it is not stated in the description of the electrical appliance that ice cubes can be added, please do not put ice cubes into the water tank, so as not to block the water inlet and cause negative pressure to damage the machine).
