Process flow of magnesium oxide production line

The magnesium oxide production line can be divided into light burned magnesium oxide production line and heavy magnesium oxide production line. Zhongjia Heavy Industry can provide a complete set of magnesium oxide production line equipment, including rotary kiln, preheater, vibration feeder, crusher, ball mill, bucket elevator, screw conveyor and other equipment. There are many kinds of production processes of magnesium oxide, including heavy magnesium oxide, light magnesium oxide, and magnesium oxide. Heavy magnesium oxide can be divided into light magnesium oxide and heavy magnesium oxide, and light magnesium oxide can also be divided into what content. Raw ore classification: magnesite (magnesite), dolomite, serpentine

Process flow of magnesium oxide production line: how to beneficiate magnesium oxide? What is the beneficiation process flow of magnesium oxide? Light calcined magnesium oxide: magnesium oxide formed by calcining magnesium compounds in magnesite ore at 700~900 ℃, also known as active magnesium oxide. The production process generally includes beneficiation, sintering, drying, screening, crushing, crushing and finished products. Reburned magnesium oxide: calcined at a temperature above 1000 ℃.

Environmental protection measures for magnesium oxide production line:

1. The combustion equipment uses energy-saving burners to automatically control the air volume of the Z best, reducing the incomplete combustion loss of the fuel.

2. The refractory bricks of the rotary kiln adopt the composite bricks with light thermal insulation in the outer layer and fire resistance and wear resistance in the inner layer to reduce the heat dissipation of the outer surface of the rotary kiln. A vertical preheater is set at the end of the rotary kiln to fully utilize the high-temperature flue gas generated by the rotary kiln combustion to preheat the materials in the preheater, so that the materials can be partially decomposed in the preheater, which increases the system output by 40% and the thermal efficiency by 30%. A vertical cooler is set at the head of the rotary kiln to preheat the secondary air to 600 ℃ by making full use of the heat contained in the high-temperature calcination discharge of the rotary kiln, so as to improve the thermal efficiency. The kiln head adopts the integrated design and construction of vertical cooler and kiln head cover, with small floor area and good sealing, effectively avoiding the unorganized emission of hot waste gas.

3. The kiln tail has good environmental protection and dust collection. The cyclone dust collector and pulse bag dust collector are used for secondary dust removal, and the emission concentration is lower than the national standard.

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