Phosphorus Gypsum Production Line,Phosphogypsum Equipment

Description

Phosphogypsum plant is composed of hot air furnace, preheating system, calcining system, dust collecting system, modifying system, conveying system, packing system and storage system.
Phosphorus gypsum refers to the gypsum formed as a by-product of the production of fertilizer from phosphate rock. Phosphorus gypsum production line is mainly composed of gypsum (CaSO4·2H2O).

Application of Phosphogypsum Equipment

After the phosphogypsum is treated with our production line, it can be used as construction gypsum and agricultural gypsum.

Technology of Phosphorus Gypsum Production Line

Two-step treatment. The first step is to remove the free water in the phosphogypsum raw material (the process is also called preheating). Hot air and phosphogypsum raw material is mixed during going through hot air tube. The second step is to remove part of the crystal water in the preheated phosphogypsum.

Working Process of Phosphogypsum Equipment

The basic process of making gypsum powder is: phosphorus gypsum raw material —— preheating —— calcining —— dust collecting —— pin mill modifying —— silo—— packing machine

Features of Phosphorus Gypsum Production Line

1. Both the preheating system and the calcining system use the same energy source: hot air furnace. This makes the production line more energy-saving and less investment cost.
2. The pin mill or ball mill is arranged after calcining. It modifies the phosphorus gypsum, and makes phosphogypsum equipment have stable performance.
3. Horizontal dust collecting system improves the filtering result.
4. Hot air is recycled. More energy is saved and the production cost is lower.
5. DCS control system is adopted in the production line. It supplies more automatic control level, much stable running performance, and more reliable quality.

Installation of Phosphorus Gypsum Production Line and Training to Operators

1. Engineers and technicians from our company will be dispatched to the installation site to give instruction in the installation and commissioning work.
2. The buyer shall supply welding workers and fitters to cooperate in the work of installation and commissioning.
3. During the installation and commissioning, the buyer’s operators will be trained in respect of operation, trouble-shooting and maintenance by the technicians and engineers.

Gypsum Powder Machine
Gypsum is a soft sulfate mineral composed of calcium sulfate dehydrate, with the chemical formula CaSO4·2H2O. To make gypsum as construction material, calcination process is needed, and part crystal water will be removed from gypsum. The gypsum powder machine is composed of crushing system, grinding system, calcining system, energy supply system, conveying system, packing system and storage system. ...

FGD Gypsum Production Line
Flue-gas desulphurization (FGD) is a set of technologies used to remove sulfur dioxide (SO2) from exhaust flue gases of fossil-fuel power plants and from the emissions of other sulfur oxide emitting processes. The FGD gypsum production line is composed of hot air furnace, preheating system, calcining system, dust collecting system, modifying system, conveying system, packing system and storage system. ...
