Vibrating fluid bed dryer for chemical powder

Vibrating fluid bed dryer for chemical powder

Working Principle

Vibration fluid bed is a new technology developed on the basis of static fluid bed. Mechanical vibration is added on the fluid bed. Wet material particles enter the air stream and form a fluid bed. The material is ejected due to exciting force. Vibrations of an air distributing plate incite the fluidization of material particles and the movement of material in the fluid bed. The fluid material contacts the hot air and at the same time carries on heat and mass transfer. The dried product is dischaged through the discharge port.

Characteristics

1. Uses the advanced vibrofluidization technology, the damage of dried material particle surface is small.

2. Steady movement, good adaptability.

3. Vibrations cause fluidization, the drying air flow rate is reduced, and a few particles are entrained.

4. The material residence time is consistent, product quality is uniform.

5. It is used for the drying of heat sensitive material in short time, such as, the surface water

drying of CUSO4·5H2O contained crystal water, MgSO4·7H2O.

Applicable scope

Can be used in dry or cooling process, applicable to the particle bulky or particles and not easy flow of irregular of products, or because to make particles less demanding and keep complete fluidization velocity of products and easy to bond, sensitive to temperature drying and contain materials gesso product surface water removal from.

Spare parts

Kneader is an ideal equipment to knead, mix for polymerize material with high viscosity and elasto plastic. Each set of kneader has two pieces of sigma blades inside the w type mixing chamber. It is widely used to knead, mix, crush, disperse and re-polymerize high viscosity paste or elastoplastic materials, which can not be processed by the general powder mixers and liquid blenders. It can be used in industries required for high density kneading such as agrichemical,  chemical,  rubber,foodstuff and pharmaceutical preparation. The effect is better than mixer.  Kneader is a special mixing equipment with two blades.  Fast one usually rotates at a speed of 42 revolutions per minute, slow one at a speed of 28 revolutions per minute. Different speeds make mixing material get homogenate quickly.
