ZK Corp began to manufacture equipments for Mg smelting industry from 1988, and focused on the technology upgrading and utilization. During 2003-2005, the company invented Vertical Pre-heater for the calcination of dolomite. This kind of new pre-heater saves fuel by 40% and increases the output by 30%. The exhaust gas is recycled and dust emission can be controlled under 50mg/m3. This kind of new pre-heater takes up more than 85% in the market share.
ZK Corp has got the patent of energy-saving rotary kiln, vertical pre-heater and vertical cooler. Pidgeon process is applied in the company’s Mg smelting technology, this kind of process is advanced and reliable technology.
Magnesium Calcination Process Flow:
Step 1: Calcined - The calcined dolomite granular
a. Process introduction: As a result of mining dolomite is too large in volume, so crushing and calcining bulk dolomite, make its become particles.
b. Main equipments:Jaw Crusher,Conveyor,Vibrating screen,Vertical preheater,Rotary kiln,Vertical cooler,etc.
Step 2:Grinding and balling - Raw material production and storage
a. Process introduction: Calcined dolomite, using a ball mill and other equipment to the grinding ball material, storage after production well.
b. Main equipments:Electronic batching scale,Bucket elevator, Ball mill, Screw conveyer ,FU chain conveyor,etc.
Step 3:Reduction treatment - Reduction treatment raw materials
a. Process introduction: Refine the raw materials, product the qualified products and sales.
b. Main equipments:Reduction furnace,Wind machine Vacuum pump,Jet pump,etc.
Step 4:Refine - Produce products
a. Process introduction:Use of a series of equipment, refine the raw material, create quality products and sales them.
b. Main equipments:Refining furnace,Electronic moisture device,Pouring pump,Continuous casting machine,etc.
