Fluidized bed dryer for ceramic particles

Color ceramic particles are made of kaolin, feldspar, quartz and clay as the main raw materials, plus inorganic high-temperature colorants, fired at high temperature. It has the characteristics of anti-skid and wear-resisting, environmental protection and corrosion resistance, low water absorption, bright color, high-grade and beautiful, never fade, hard and solid, long service life and so on. Color ceramic particles in recent years is a new type of pavement material commonly used in countries around the world. It has anti-skid and wear-resistant, environmental protection and corrosion resistance, low water absorption, bright color, high-grade beautiful, never fade, hard and solid, long service life and so on. The product is widely used in highways, airports, airfield runways, railway stations, subways, bus stops, parking lots, parks, squares, schools and hotels, restaurants, office buildings, office buildings and other pavement paving and marking. The product in the construction of landscape urban areas, landscape district, beautify the urban environment is the first new material on the market.

Ceramic granule fluidized bed dryer is made by applying vibration on ordinary fluidized bed. Put a layer of material on the feeding plate, vibration of the feeding plate, when the vibration acceleration is greater than the acceleration of gravity, the material layer begins to expand, the so-called vibration fluidization state. At this time the material placed on the conveyor plate produces strong mixing, and it is easy to move horizontally and inclined. In this condition, the use of convection, conduction, radiation to the material layer to supply heat, can achieve the purpose of drying. Due to the strong vibration of the bed, the resistance to heat and mass transfer is reduced, which improves the drying rate of vibrating fluidized bed, and at the same time makes it not easy to fluidize or fluidize a large number of easy to produce a large number of entrainment of mass or highly dispersed materials can be successfully dried, overcoming the common fluidized bed is prone to return to mixing, ditching flow, sticking to the wall and other phenomena.

Ceramic particles fluidized bed dryer equipment advantages:

1、Objects are heated evenly, heat exchange is sufficient, drying intensity is high.
2、The vibration source is driven by vibration motor, which is balanced in operation and convenient in maintenance.
3、Uniform fluidization, no dead space and blowing through phenomenon, you can get uniform drying, cooling, humidifying products.
4、Good adjustability, wide adaptability, material layer thickness and moving speed in the machine as well as full amplitude change can be realized stepless adjustment.
5、Small damage to the surface of the material, can be used for the drying of fragile materials, material particles irregularly does not affect the working effect.
6, the use of fully closed structure, effectively preventing the material and the outside air cross-infection, clean operating environment.

Fluidized bed drying technology is a new type of drying technology developed in recent years, the process of bulk material is placed on the hole plate, and the lower part of the gas conveyor, causing the material particles in the gas distribution plate movement in the gas stream is suspended, resulting in material particles and gas mixing layer, as if the liquid boiling. In the fluidized bed dryer, the material particles are fully contacted with the gas in this mixed layer, and the heat and moisture transfer between the material and the gas is carried out. Currently it is widely used in chemical, food, ceramics, medicine, polymer and other industries.
