Problems solved by technology

However, in such a production system, the minerals must be dry-milled before wet-grinding to reduce their particle size, and the dry-grinding process consumes a lot of energy, and the equipment is noisy, which affects the environment

Embodiment 1

[0029] figure 1 It is the kaolin production system according to the first embodiment of the present invention. In this production system, raw kaolin ore is crushed by the crusher 1 with an average particle size of less than 5 mm, and then enters the wet ball mill 3 for grinding. After being ground by the wet ball mill 3, the particle size of kaolin is reduced to 325 mesh, and then it enters the ultrafine grinder 9 for re-grinding through the iron remover, further reducing the particle size of kaolin to <2 μm, and the kaolin with a particle size of <2 μm accounts for After treating 90% of the total amount of kaolin, drying, depolymerization and calcining are carried out to obtain kaolin powder with a particle size of 6000 mesh and a whiteness greater than 93%.

[0030] In the first embodiment, the production system includes a crusher 1, a silo 2 connected to the crusher 1, a wet ball mill 3, a storage tank 4, a water reservoir 5, a transition mixing tank 61, and a transition mi...

Embodiment 2

[0046] Please refer to image 3 , the difference between the production system in this embodiment and the first embodiment is that: the transitional mixing tank 61, the slurry mixing tank 62 and the iron removal system 7 of the production system in this embodiment do not need to be provided with a frequency converter 611 , and directly use the pump to pump the material, and the concentration meter connected with the iron removal system 7 may not need to be set. The transition mixing tank 61 , the slurry mixing tank 62 and the water storage 5 do not need to be provided with an electric regulating valve 52 . When the regulator is not used, the concentration of the slurry and the amount of water added can be manually detected, and the purpose of the present invention can still be achieved by using the system provided in this embodiment to produce kaolin.

Embodiment 3

[0048] Please refer to Figure 4 , the difference between the production system in this embodiment and the first embodiment is: the production system in this embodiment does not need to be provided with electromagnetic flowmeter 51, electric control valve 52, frequency converter 611, belt scale 211, metering pump 31, concentration Count 71. When using the system in this embodiment to produce kaolin, the measurement of each material can be done manually, and the purpose of the present invention can be achieved by using the system in this embodiment.

Abstract

The invention provides a superfine kaolin production system and a use method thereof. The superfine kaolin production system comprises a crusher and a superfine grinder which are sequentially connected. The superfine kaolin production system further comprises a wet grinding machine, kaolin entering the wet grinding machine is crushed by the crusher to be smaller than 50 mm in grain size, and the kaolin enters the superfine grinder after coming out from the wet grinding machine. By adopting the superfine kaolin production system to produce kaolin, yield per hour is 10.5 tons, and when kaolin is coarse grinded to be 325 meshes, each ton of products consumes 50 kilowatt hour of electricity. In addition, when materials are superfine grinded to be with more than 90% of the materials smaller than 2 um m in grain size, each ton of products consumes only 90 kilowatt hour of electricity. The superfine kaolin production system further has functions of reducing dust and noise.

Description

technical field [0001] The invention relates to a kaolin production system, in particular to an ultrafine kaolin production system and a method for using the same. Background technique [0002] The main component of kaolin is silicate, of which Al 2 o 3 Content 37.5-44.5%, SiO 2 It is 44.8-53.1%, and contains a small amount of oxides of iron, sodium, potassium, titanium, calcium, and magnesium. Because of its large color difference, stable chemical properties, low price, and strong hiding power, it has been widely used in ceramics, water-based paints, latex paints, paper industry and textile coatings. Coal series kaolin raw ore needs to be crushed, dry or wet grinding, slurry preparation, wet ultra-fine grinding, drying, depolymerization, calcining and depolymerization to obtain products. However, in the current technology, the raw materials are habitually processed into particles below 325 mesh before pulping. In this step, the particles of 30mm are often treated with a...
