       铝矾土(俗称高铝粘土或高铝矾土)是指含耐火粘土的一种矿物。耐火粘土，是指耐火度大于1580，可广泛地用于各种工业窑炉的炉衬材料，主要成分为铝硅质的矿物原料，氧化铝是铝矾土的主要有益成分，氧化铝含量越高，则耐火度也越高。铝矾土熟料的耐火度随氧化铝含量的增加和煅烧温度的提高而提高。铝矾土的氧化铝含量达71．8％时，其耐火度>1800。

       耐火材料行业所称的铝矾土通常是指煅烧后Al2O3>=48、含Fe2O3较低的铝土矿，高铝矾土熟料是经过煅烧的铝矾土矿。熟料为灰白浅黄及深灰色，它主要用于高铝质耐火材料，也可用来制作电熔棕刚玉。高铝矾土熟料是按AL2O3含量及Fe2O3、TiO2、CaO+MgO、K2O+Na2O等杂质含量和熟料体积密度与吸水等项指标来分级的。

       轻烧铝矾土又称轻烧粉，是净水剂聚合氯化铝的原材料，是铝矾土经过加工生产出来的矿粉材料，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。密度3.94g/cm3，硬度13，不透明，质脆，极难熔化；不溶于水，能溶于 、 。铝矾土常用规格：0-3mm 3-5mm 5-8mm 8-10mm 100目200目等，可按客户要求进行调整。

      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。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

       铝矾土根据物理、化学性质的差别。按主要用途可以分为四大类：

       1、冶金级铝矾土；指提炼金属铝或冶炼氧化铝所用的铝土矿，一般来说铝硅比应大于2.6方可使用。

       2、研磨级铝矾土；主要用于生产高铝水泥和各种磨料、磨具。

       3、耐火级铝矾土；用于生产各种定形和不定形耐火材料。

       4、电焊级铝矾土；工业上用于生产电焊条。

       1、炼铝工业。用于国防、航空、汽车、电器、化工、日常生活用品等。

       2、精密铸造。矾土熟料加工成细粉做成铸模后精铸。用于 、航天、通讯、仪表、机械及部门。

       3、用于耐火制品。高铝矾土熟料耐火度高达1780，化学稳定性强、物理性能良好。

       4、硅酸铝耐火纤维。具有重量轻，耐高温，热稳定性好，导热率低，热容小和耐机械震动等优点。用于钢铁、有色冶金、电子、石油、化工、宇航、原子能、国防等多种工业。它是把高铝熟料放进融化温度约为20002200的高温电弧炉中，经高温熔化、高压高速空气或蒸汽喷吹、冷却，就成了洁白的“棉花”硅酸铝耐火纤维。它可压成纤维毯、板或织成布代替冶炼、化工、玻璃等工业高温窑炉内衬的耐火砖。消防人员可用耐火纤维布做成衣服。

       5、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效果甚佳。

       6、制造矾土水泥，研磨材料，陶瓷工业以及化学工业可制铝的各种化合物。

Introduction of bauxite

Bauxite (commonly known as high-alumina clay or high bauxite) refers to a kind of refractory clay minerals. Refractory clay, is refers to the refractoriness is greater than 1580 , can be widely used in all kinds of industrial furnace lining materials, main ingredients for aluminium siliceous mineral raw material, alumina is the main beneficial components of bauxite, alumina content is higher, the higher refractoriness. Refractoriness of bauxite clinker with the increase of the alumina content and the increase of calcination temperature. Bauxite alumina content of 71.8, the refractoriness > 1800 .

Bauxite, often referred to as referred to in the refractory industry after calcining Al2O3 > = 48, contain low Fe2O3 bauxite, high bauxite clinker is after calcined bauxite ore. Clinker to pale yellow and dark gray, it is mainly used for high aluminum refractory material, can also be used to make the fused corundum. High bauxite clinker is according to the content of AL2O3 and Fe2O3, TiO2, CaO + MgO style, K2O + Na2O and other impurity content and clinker indicators such as volume density and bibulous to classification.

Lightly calcined bauxite is also called light burning powder, raw materials, water purifier polyaluminium chloride type bauxite is processed to produce the material, the main ingredient is aluminium oxide, hydrate alumina containing impurities, is a kind of soil minerals, white or gray, brown yellow or light red by iron. From 4 to 3.9 g/cm3 density, hardness, 1 3 is not transparent, very brittle, extremely difficult to melt; Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution.

Bauxite commonly used specifications: 0 to 3 mm for 3 to 5 mm 5-8 mm 8-10 mm 100 mesh, 200 mesh, etc., can be adjusted according to customer's request.

Bauxite classification

The difference between bauxite according to the physical and chemical properties. According to the main application can be divided into four categories:

1, metallurgical grade bauxite; Refers to the refining of aluminum or used in the smelting alumina bauxite, generally al-si ratio should be greater than 2.6 before use.

2, grinding grade bauxite; Mainly for the production of high alumina cement and various abrasive, abrasive.

3, refractory grade bauxite; Used in the production of a variety of shapes and monolithic refractories.

4, welding grade bauxite; Industry for the production of welding electrode.

Bauxite purposes

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, 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.
