Product introduction                                                                                                          

It is also known as alumina or bauxite, main ingredients are aluminum oxide, hydrate alumina containing impurities, is an earthy mineral. White or grey, brown yellow or light red by iron. 2.4 2.5 g/cm3 density, hardness, 1 ~ 3 is not transparent, very brittle and very difficult to melt, insoluble in water, soluble in sulfuric acid, sodium hydroxide solution, it is mainly used for aluminium, refractory material.

Bauxite Classification Introduction                                                                                    

1.Classified according to the type of bauxite raw materials:

(1) raw bauxite, alumina original ore (natural sedimentary rock class).

(2) the calcined bauxite, the raw bauxite after high temperature calcination (1200 ~ 1700 ℃) is called the calcined bauxite.

2.Calssified according to the different calcining kiln where the bauxtie is divided into:

(1)Shaft kiln bauxite

(2)Rotary kiln bauxite 

(3)Round kiln bauxite

3.Calcined Bauxite according to different uses for division:

(1) the refractory grade bauxite

(2) the grinding grade alumina

(3) the welding grade bauxite

Manufacturing processes                                                                                                  

Raw material fed into the calciner at high temperature calcination,part drying may also be part of the way. Calcined material through the jaw crusher or hammer crusher, then sent Rulei Meng mill. After crushing the material into the mill production system, the entire milling, grading and other operations processes and procedures are completed within the mill automation, operating crew should pay close attention to the cabinet meter data. Qualified bauxite powder released by the discharge valve, packaging products.

Product Usage                                                                                                

1, aluminium industry, used for national defense, aerospace, automotive, electrical, chemical industry, daily necessities, etc.

2, precision casting, bauxite clinker made after mold precision casting processed into fine powder, used in military industry, aerospace, communications, instrumentation, machinery and medical equipment department.

3, used for refractory products - high bauxite clinker as high as 1780 ℃, refractoriness strong chemical stability, good physical properties.

4, aluminum silicate refractory fiber with light weight, high temperature resistance, good thermal stability, low thermal conductivity, heat capacity is small and the advantages of resistance to mechanical shock. Used in iron and steel, nonferrous metallurgy, electronics, petroleum, chemical, aerospace, atomic energy, defense and other industries. It is the high alumina clinker in the melting temperature of about 2000 ~ 2200 ℃ high temperature electric arc furnace, via high pressure of high temperature melting, high-speed air or steam injection, cooling, became a white cotton - silicate aluminum refractory fiber. It can be pressed into fiber blanket, board or woven cloth instead of smelting, chemical industry, glass and other industrial furnace lining brick. Firefighters available refractory fiber cloth to make clothes.

5, magnesia and bauxite clinker as raw material, adding proper binder, used for pouring ladle whole ladle lining has particularly good effects.

6, manufacture alumina cement, abrasive materials, ceramic industry and chemical industry can be of aluminum compounds.

Note                                                                                                                                  

the transport packaging to prevent breakage, in order to avoid leakage or mixed with debris, should not be stacked together with other materials.
