316L Hot Air ZLG Fluidized Bed Dryer Drying Calcium Magnesium Phosphate Fertilizer

Function:

Calcium magnesium phosphate fertilizer is a gray-green or gray-brown powder with a phosphorus content of 12% to 18%. The main component is α-Ca3(PO4)2 that is soluble in citric acid. It also contains magnesium and a small amount of silicon and other elements. Magnesium is beneficial to the formation of chlorophyll, and silicon can promote the growth of crop fiber tissue, so that plants have better ability to prevent lodging and pests and diseases. It works well as a base fertilizer when cultivating large seedlings, and plants can slowly absorb the required nutrients.

Usage:

Calcium magnesium phosphate fertilizer is insoluble in water, non-toxic, non-corrosive, non-hygroscopic, non-caking, and is a chemical alkaline fertilizer. It is widely used in various crops and acidic soils with phosphorus deficiency, especially in acidic red soils in the south where calcium and magnesium leaching is more serious.

Introduction:
Fluidized bed operation has the advantages of good mixing of solid particles and large surface area for heat and mass transfer between gas and solid phases, but its main disadvantages are: ① The particles to be treated should be larger than 50~100μm, otherwise it is easy to form channel flow and stagnation zone; ② When the particle size distribution is wide, entrainment is serious; ③ When the particle temperature is high, it is easy to form lumps or agglomerations; ④ For non-spherical particles such as wheat grains, fibers, slices, etc., it cannot be fluidized well.
Vibrating fluidized bed is a very successful modified fluidized bed. It is a fluidized bed supported on a set of springs and powered by an excitation motor. The bulk material put into the dryer is thrown to the outlet end under the perforated plate by the excitation force and output to the outlet VI end. Hot air is blown in from under the perforated plate, passes through the material layer, transfers heat to the material, and carries the vaporized water from the material and is discharged from the exhaust port, thereby drying the material. Because the material is in motion due to mechanical vibration in the vibrating fluidized bed, dynamic drying can be achieved by blowing in an appropriate amount of hot air, so the thermal efficiency is high and the material is dried evenly.

Scope of application:
Fluidized bed dryers are suitable for drying, cooling and humidifying various granular material crystals and powder and granular mixtures.
1. Pharmaceutical and chemical industry: various tablet particles, boric acid, borax, hydroquinone and various additives, etc.
2. Food and building materials industry: wine lees, monosodium glutamate, sugar, salt, granular chicken essence, slag, bean curd seeds, etc.

Features of vibrating fluidized bed:
1. Objects are heated evenly, heat exchange is sufficient, and drying intensity is high.
2. The vibration source is driven by a vibration motor, which is balanced in operation and easy to maintain.
3. Fluidization is uniform, without dead gaps and blow-through phenomena, and uniform drying, cooling and humidification products can be obtained.
4. Good adjustability, wide adaptability, material layer thickness, moving speed in the machine and full amplitude change can all be adjusted steplessly.
5. Little damage to the surface of the material, can be used for drying fragile materials, and irregular material particles do not affect the working effect.
6. The fully enclosed structure effectively prevents cross infection between materials and outside air, and ensures a clean working environment.
