Introduction
Rotary kiln for magnesium oxide is a kind of kiln calcinating smashed magnesium powder by heated air.The kiln headcover and combustion apparatus. The barrel is a part for heating, adopting a high-quality calm steel coil. Because of particularity in calcination, kiln generally uses a variable diameter barrel.
Rotary Kiln for Magnesium Oxide Performance Feature
Rotary kiln for magnesium oxide can be divided into transition zone, burning zone, and cooling zone. After entering kiln, materials go through resolving, calcining and cooling. Rotary kiln for magnesium oxide’s advanced technology improves the quality of materials and enhances materials’ abrasive resistance.
Rotary kiln for magnesium oxide has a high quantity per unit volume, which increases the material layer’s thickness and rotating speed to heat materials evenly.
Rotary kiln for magnesium oxide has so many advantages like high thermal cycle utilization, high thermal efficiency, low fuel consumption, low power consumption and low production costs.
Rotary Kiln for Magnesium Oxide Working Principle
Rotary kiln for magnesium oxide is supported by a roller device and controlled by the wheel stop device. It has a reliable seal for using shell seal in kiln head hood and axial contact seal in kiln tail hood. Rotation of kiln facilitates the mix of the materials in a rotary kiln to make materials fully mixed and react with each other. The burning pipe produces a lot of heat. Heat is conducted to materials by flame radiation, convection of hot air and conduction of kiln bricks. Materials move forward through kiln’s slope and rotation. Eventually, materials go into cooler from kiln head hood.
Rotary kiln for magnesium oxide’s working process can be divided into nine steps: mineral separation, entry, sintering, manual screening, inspection, mixed production, smashed product, examination, storage.
Rotary kiln for magnesium oxide ‘s materials are chosen from quality products(30-40mm). Materials go through calcining, cooling, grinding and molding. Then be mixed with ferrosilicon powder and fluorite powder. Reduce and produce extensive magnesium under 1200 to 1250 degrees centigrade and 1.33pa Vasco in a reduction furnace. After a series of processes such as flux refining, ingot casting, and surface treatment, produce finished magnesium ingots.
