Slg Fluid Bed Dryer / Vibrating Bed Dryer / Chemical Product Drying Machine

Principle

On the basis of absorbing foreign technologies, the company has independently developed and produced a dual mass fluidized bed drying device, which is mainly composed of a lower chamber, a middle chamber, a base, a fluidized bed plate, a spray hole, a vibration system, a material receiving system, a forced draft fan system, etc. The box type exciter is equipped with two vibrating motors, which generate a vertical component and a horizontal component through the action of a spring (resonance spring) by rotating one less horizontal exciting force. The vertical component will throw up the materials on the bed plate together through the high-pressure hot air formed by the spray hole, so that the materials are in a fluidized state, while the horizontal component, It can make the materials move forward evenly at a certain speed (the wind speed, material layer thickness and discharge speed can be adjusted), and the materials are discharged through the overflow weir and discharge hopper, so as to complete the drying operation.

Features

The thickness of the material layer can be set according to the characteristics of the material, - generally ≤ 30mm, so as to greatly extend the residence time.

The bed thickness and hole diameter can be configured according to the equipment size and wind speed.

The spray holes on the bed surface can be selected in various structural forms.

It can be equipped with an elastic support structure to make the drying bed area larger and the vibration installed power of the middle chamber smaller.

It is especially suitable for the drying or cooling of large batch, continuous and viscous powder materials.

In 2009, the company innovatively designed and produced 5 sets of citric acid special dual mass vibration dryers, which were successfully applied; The innovative improved design adopts the imported air spring damping form, which greatly reduces the dryness. The service life of the equipment is improved.

Applications

Drying and cooling of citric acid, sodium sulfate, polyacrylamide and other low viscosity materials.
