铝矾土又称矾土或铝土矿，主要成分是氧化铝，系含有杂质的水合氧化铝，是一种土状矿物，白色或灰白色，因含铁而呈褐黄或浅红色；铝，制耐火材料等。

元丰铝矾土主要成分是氧化铝（Al2O3），系含有杂质的水合氧化铝，是一种土状矿物，等级含量也主要是根据氧化铝含量的多少来决定的。铝矾土用途多样，可以用于铝工业中提炼金属铝、作耐火材料和研磨材料，以及用作高铝水泥原料。矿石用途不同，其质量要求各异。

铝矾土加工工艺流程：

1、高温煅烧：原料送入煅烧炉进行高温煅烧，部分也可采用烘干的方式进行。

2、破碎制粉：煅烧后的物料经过颚式破碎机或者锤式破碎机破碎，然后被送入雷蒙磨粉机。

3、破碎后物料进入磨粉机生产系统后，整个磨粉、分级等操作流程均在磨粉机内自动化完成，操机人员应当密切关注电控柜仪表数据；合格的铝矾土粉由排料阀释放，包装成品。

1、炼铝工业；

2、铸造；

3、用于耐火制品；

4、以镁砂和矾土熟料为原料，加入适当结合剂，用于浇注盛钢桶整体桶衬。

5、制造矾土水泥，研磨材料，陶瓷工业以及化学工业可制铝的化合物。

6、硅酸铝耐火纤维。

Introduction of bauxite

Alumina or as a bauxite bauxite, main ingredients are aluminum oxide, hydrate alumina containing impurities, is an earthy mineral. White or grey, brown yellow or light red by iron. From 4 to g/cm3 density, hardness, 1 ~ 3, opaque, very brittle. Very difficult to melt. Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution. Mainly used for aluminium, refractory material.

Consists mainly of bauxite alumina (Al2O3), containing impurities of hydrate alumina, minerals, is a kind of soil is mainly according to the content of alumina grade levels, how much to decide. Bauxite use diversity, one of the most important purpose is: refined aluminum in aluminum industry, refractory and abrasive materials, as well as used as high alumina cement raw material. Different ore purpose is different, its quality requirements. Global mined bauxite, more than 85% is used for production of alumina, and aluminum production. Used for the production of non-metallic alumina 10%, the rest of the application for the smelting practice of bauxite.

Raw bauxite classification specifications: bauxite, bauxite clinker, bauxite aggregate, bauxite powder.

The application of bauxite

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

2, the precision casting. Alumina 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, chemical stability strong, and good physical properties.

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

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

6, silicate aluminum 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.
