Magnesium oxide production line can be divided into light burned magnesium oxide production and heavy magnesium oxide production line. Zhongjia Heavy Industry can provide a full set of magnesium oxide production line equipment, including rotary kiln, preheater, vibrating feeder, crusher, ball mill, bucket type Hoist, screw conveyor and other equipment. Magnesium oxide has heavy magnesium oxide, light magnesium oxide, and many production processes of magnesium oxide. There are many types of heavy burned magnesium oxide and heavy burned magnesium oxide, and how much light magnesium oxide is divided into. Original ore classification: magnesite ore (lingsite), dolomite ore, serpentine.

Process flow of magnesium oxide production line: How to beneficiate magnesium oxide? What is the beneficiation process of magnesium oxide? Lightly burned magnesia: Magnesium oxide formed by calcining magnesite ore at 700 to 900 degrees Celsius is also called active magnesia. The production process is generally, beneficiation, sintering, drying, screening, crushing, crushing, and producing finished products. Reburned magnesia: calcined at temperatures above 1000 ° C.

Environmental protection measures of magnesium oxide production line:

1. The combustion equipment uses energy-saving burners to automatically control the best air distribution and reduce the incomplete combustion loss of fuel.

2. The refractory bricks of the rotary kiln adopt light outer insulation and the inner fire-resistant and wear-resistant composite bricks to reduce the heat dissipation of the outer skin of the rotary kiln. There is a vertical preheater at the end of the rotary kiln, which makes full use of the high temperature flue gas generated by the combustion of the rotary kiln, preheats the materials in the preheater, causes the materials to partially decompose in the preheater, and increases the system output by 40 %, Thermal efficiency increased by 30%. There is a vertical cooler at the head of the rotary kiln, which makes full use of the heat contained in the high-temperature calcined white material of the rotary kiln to preheat the secondary air to 600 ℃, so that the thermal efficiency is improved. The kiln head adopts the integrated design and construction of vertical cooler and kiln head cover, which occupies a small area and has good sealing, which effectively avoids the unorganized discharge of hot exhaust gas.

3. Good environmental dust collection in the kiln tail, using cyclone dust collector and pulse bag dust collector for secondary dust removal, the emission concentration is lower than the national standard.

4. The level of automation is high. The adjustment, control and alarm of the operation of the production system are controlled by PLC in the main control room, with fewer on-site operators and high labor efficiency.
