After the natural bauxite ore is fired at high temperature, the block material formed becomes the high alumina material.1. High temperature calcination: raw materials are sent to the calciner for high temperature calcination, and some can also be dried.2. Crushing and pulverizing: after the calcined

Bauxite is mainly composed of aluminum oxide, which is a kind of gray white or brown yellow to light red (due to iron content) earthy mineral. The density is 3.45g/cm3, the Mohs hardness is 1-3, opaque and brittle.Bauxite is often used as the raw material of high alumina refractories and fused brown

Mullite Sand is aluminum silicate refractory materials, normally used in stainless steel precisioncasting technology.

In July 2018, RMPI (Raw Materials Price Index) stands at 237.83, down by 2.74% compared with the previous month; up by 36.53% compared with the same period of 2017. The price of bauxite remains stable, with continuing shortage of ore supply; fluctuation situation of magnesia lasts for nearly 1 year,

Referred to as refractory brick. Refractory material with a certain shape and size. According to the preparation process, it can be divided into bricks, brick, electric melting brick (Cast Brick), the refractory insulating bricks; according to the shape and size, it can be divided into standard brick, ordinary brick, specific rotation.

Previous policy Chinese government has enforced the environment law seriously this year.
