Introduction to Kaolin and Its Importance

Caulino is a non-metallic mineral, a kind of clay and clay rock dominated by kaolinite clay minerals. Because it is white and delicate, it is also called white cloud soil.

Os minerais de caulino são compostos por minerais de aglomerados de caulinite, tais como caulinite, dickite, perlite, halloysite, etc. O principal componente mineral é a caulinite.

A fórmula química cristalina de caulinite is 2SiO2·Al2O3·2H2O, and its theoretical chemical composition is 46.54% SiO2, 39.5% Al2O3, and 13.96% H2O. Kaolin minerals belong to the 1:1 type layered silicate. The crystals are mainly composed of silicon-oxygen tetrahedra and aluminum hydroxide octahedra. Among them, the silicon-oxygen tetrahedra are connected in a two-dimensional direction to form a hexagonal arrangement by sharing a vertex angle. In the grid layer, the apex oxygen is not shared by each silicon-oxygen tetrahedron; the apex oxygen of the silicon-oxygen tetrahedron layer and the oxygen-assisting octahedral layer form a 1:1 unit layer.

Wide Range of Applications of Kaolin

Kaolin has a wide range of uses, as it is a versatile material that serves critical roles in primary, secondary, and specialty applications. Such as:

• Primary applications: It is mainly used in papermaking, ceramics, and refractory materials.
• Secondary uses: Followed by coatings, rubber fillers, enamel glazes, and white cement raw materials.
• Specialty applications: A small amount is used in plastics, paints, pigments, grinding wheels, pencils, daily cosmetics, soaps, etc.
• Outras utilizações: Pesticides, medicines, textiles, petroleum, chemicals, building materials, national defense, and other industrial sectors.

The Need for Kaolin Recycling

Kaolin will produce a large amount of tailings after ore dressing and recycling. As the recycling of kaolin tailings is low, with the continuous accumulation of tailings, it will encroach on a large amount of land, pollute water quality, cause vegetation damage and soil erosion, and even cause Debris flow, seriously affecting the ecological environment. Therefore, comprehensive utilization of kaolin tailings and recycling them can effectively prevent waste of resources and damage to the environment. Our 150TPH recycling plant addresses these environmental concerns while recovering valuable material.

150TPH Recycling Process Overview (Flowchart Explained)

1. Utilize uma empilhadora ou escavadora para alimentar as matérias-primas na tremonha, e um alimentador por baixo da tremonha alimentará uniformemente as matérias-primas no transportador de correia, e a correia transportadora will send the raw materials to the log washer. The function of the log washer is to disperse, stir, and clean the agglomerated kaolin clay.
2. Introduzir o esfregão de atrito para continuar a limpeza. A função da lavadora de atrito é esfregar e remover melhor o lodo pegajoso do caulim.
3. After washing by the attrition scrubber, the material then enters the ecrã trommel to screen out big waste stones, which are sent to a far place by belt conveyor, and the material under the screen enters the double spiral sand washer.
4. O extravasamento da primeira fase da espiral dupla máquina de lavar areia is kaolin concentrate, the underflow goes to the second stage of the spiral sand washer for further washing, the overflow of the second stage is kaolin concentrate, and the underflow goes to the wheel sand washer.
5. The overflow from the wheel sand washer is the concentrate, and the underflow goes to the dewatering screen.
6. Os materiais do primeiro ecrã ecrã de desidratação are the kaolin concentrate, the over-screen materials go to the second dewatering screen for further dehydration, over screen materials of the second dewatering screen are coarse particle waste. Use a belt conveyor to send away, and under the sieve is the concentrate.
   Kaolin Concentrate under the screen of two dewatering screens into a 2# pond.
   O concentrado de caulino proveniente dos transbordos das duas lavadoras de areia em espiral e da lavadora de areia com rodas é colocado na piscina 1#.
7. Utilizar o bomba de polpa to send 1# pond concentrate into 1# cyclone group, and the overflow of the cyclone group is kaolin concentrate, underflow flows to the dewatering screen for dehydration. And under the screen of the dewatering screen is a concentrate which goes into the 2# pond. Over the screen, materials are medium particles of waste, which are transported away with a belt conveyor.
   The under-screen concentrates of 4 dewatering screens are all in a 2# pond, and they are pumped to a 2# grupo ciclone com uma bomba de polpa. O fluxo inferior do grupo de ciclones 2# vai para o crivo de desidratação e o fluxo superior é o concentrado de caulino.
8. Finalmente, o transbordo dos dois grupos de ciclones (concentrado de caulino) fluirá para a piscina de concentrado 325.
