Processing material: magnesite
Processing capacity: 150,000 tons per year
Equipment configuration: rotary kiln, preheater, cooler, electrical instrument
I. Project Overview:
Our company specializes in the production of metal magnesium smelting industry machinery and equipment, and according to the improvement of magnesium smelting process and the improvement of equipment level, constantly improve equipment performance, improve product functions, independent research and development and production of preheater successfully applied in the calcination of magnesite, fuel saving, production increase, waste gas heat recovery and utilization, but also conducive to the dust removal of flue gas, The emission index shall be below 30mg/m³.
On June 13, 2016, our company's bidding team of 9 people under the leadership of the company's senior manager Ren went to Qinghai to bid. The bidding team was composed of business representatives, process engineers, equipment engineers, electrical engineers, civil engineers and kiln engineers. After 3 days of fierce competition, the bidding work was completed, and the bidding team inspected the manufacturers one by one. After seeing the workshop site and management of my company, I fully affirmed Zheng Mine and fully recognized the processing strength of my company, and then visited the site of my company's metal magnesium project.
II. Solution:
The qualified magnesite is sent to the rotary kiln for calcining; Then the calcined magnesite, fluorite and ferrosilicon are proportioned according to a certain proportion, and then pressed into pellets by ball milling; It was put into the reduction tank under the condition of vacuuming and carried out high-temperature thermal reduction to obtain crystalline magnesium. Magnesium metal can be obtained after crystalline magnesium is remelted and refined. Including raw material reserve, magnesite calcination, grinding ball, reduction and refining sections.
III. Stock of raw materials
The magnesite is crushed to the required particle size in the mine and stored in the magnesite storage yard in the factory. Ferrosilicon and fluorite are stored directly in the factory warehouse. Reserves are considered according to the consumption required for half a month of production.
Magnesite calcining workshop
Choose energy-saving and environment-friendly rotary kiln, with vertical preheater and vertical cooler. The external magnesite with the required particle size and quality is unloaded to the material yard, the loading machine carries out the material collection operation, and the vibrating screen carries out the screening. After that, the magnesite with the particle size of 10 ~ 40mm is transported by belt to the top silo of the vertical preheater of the rotary kiln, and enters the preheater through the material pipe to exchange heat with the high temperature flue gas flowing from the rotary kiln, and the material is preheated to more than 800℃. After falling into the transfer chute, it is calcined into active calcined white in the rotary kiln at high temperature of 1250℃, and then discharged into the cooler, where the high temperature calcined white is exchanged with the cold air pumped into the fan, the active calcined white is cooled below 100℃, and the air is preheated to more than 600℃. After cooling, the activated calcined white is discharged from the cooler and transported to the ball making workshop by the scale conveyor.
