Phosphogypsum acid production line

About This Device

In the raw material section, phosphogypsum is converted into semi-hydrated gypsum through filtration and drying processes. The semi-hydrated gypsum is decomposed and calcined with silica, bauxite, coke and other ingredients in a rotary kiln to form cement clinker. The sulfur dioxide gas produced during the decomposition and calcination of gypsum is transported to the sulfuric acid production line as raw material.

How Does This Device Work?

1. The material is fed into the kiln through the kiln tail (high end) chute. Due to the inclination and slow rotation of the cylinder, the material rolls along the circumference while moving axially from the kiln tail (high end) to the kiln head (low end).

2. The material keeps rolling and moving forward in the rotary kiln. The heat source heats the rotary kiln, and the material heats up and reacts in the rotary kiln.

3. he reacted material is discharged from the kiln head and enters the next process.

Main equipment in Extraction of Zinc Oxide from Blast Furnace Ash

1.Rotary kiln: This is the core equipment of the calcination production line, used to calcine alumina raw materials under high temperature environment. Rotary kilns are usually divided into horizontal and vertical types. Horizontal rotary kilns are more commonly used. The raw materials react at high temperature by rotating the cylinder.

2. Gas generator: used to convert coal or coal coke into combustible gas to provide fuel for the rotary kiln. Common gas generators include fixed bed gas generators and fluidized bed gas generators.

3. Cyclone separator: used to separate particulate matter generated by the rotary kiln, discharge coarse particles to the bottom, and fine particles are discharged from the equipment through the cyclone tube.

4.Dust collector: removes impurities in the gas and dust generated after the rotary kiln, purifies the gas, and reduces environmental pollution.

5. ‌Intelligent temperature control system‌: Precisely control the temperature curve to ensure uniform alumina particle size, reduce impurities, and improve product consistency‌

6.‌Waste gas recovery and waste heat utilization system‌: Reduce energy consumption and carbon emissions, and meet green production standards‌
