Application of Prehomogenization of Light burned Magnesium Powder

Use of pre homogenization of light burned magnesium powder:

First, it is well known that when block raw materials (magnesite) are used for calcination in a reverberatory kiln, due to the different sizes of blocks, in the limited calcination time (burning time 2-3h), coupled with the fluctuation of calcination temperature, it is inevitable that magnesite will have under burning and over burning, so the composition of light calcined powder cannot be consistent.

Secondly, the light burned magnesia plant did not adopt partition mining or matching mining for most of the ore resources, resulting in the fluctuation of ore composition. The content of magnesia and active magnesia in the calcined light burned powder fluctuated greatly, leading to inconsistent composition.

Third, most manufacturers of light calcined powder do not have enough time for the braising furnace after the magnesite ore satin is burnt, and they directly grind the powder with Raymond and then directly package it, which also leads to inconsistent composition of light calcined powder.

The quality and composition of the light burned powder used today are not only different from different manufacturers, but also from different batches of the same manufacturer or even from the same company or batch of products, resulting in very unstable quality of the magnesium oxychloride products. In particular, the continuous detection of the content of the light burned powder will inevitably lead to the excess or shortage of the coagulant MgCI2, which will inevitably lead to the return of halogen and frost of the magnesium oxychloride products. Therefore, the quality stability of light burned powder is the key to affect the quality of magnesium oxychloride products,

Prehomogenization of light burned powder is an important means to stabilize the composition and quality of light burned powder.
