Zibo Rundi Aluminum Industry Co., Ltd

We are exporter of Calcined Alumina. According to different requirements, five series of products have been formed, including dry pressing, hot die casting, refractory, casting and setting, structural ceramic granulator, etc. It can be widely used in electronic equipment, structural ceramics, refractories, wear-resistant materials, polishing materials and other industries.

We are supplier and exporter of Calcined Alumina. Calcined alumina can be used in the polishing of different alumina products(mainly used in middle, fine polishing).It is also widely used in high-class aluminium refractory material, unshaped refractory materials, high aluminium ceramic product and advanced coating, etc, .

Al2O3 has many isomorphic crystals, and there are currently more than 10 known types, mainly three types of crystal, namely gamma-al2o3, beta-al2o3, alpha-al2o3.Which structure is different, with different properties in high temperature above 1300 s almost entirely into alpha Al2O3.

We are exporter of Bauxite. Bauxite is a soft, whitish to reddish-brown rock consisting mainly of alumina-bearing hydroxides, oxides of iron, silicon and titanium with impurities of Ca, Mg, Cr, V, P, Ga and other elements. Raw Bauxite is a major source of aluminium. Basic alumina containing minerals of Bauxites are gibbsite Al(OH)3, Boehmite g-AlO(OH) and Diaspore a-AlO(OH) Bauxite is used in a lot of industries like the chemical industry, refractory, abrasive, cement, steel, and petrol industry amongst others. In chemical, bauxite along with alumina is used in the manufacturing of aluminium chemicals. In refractory, it is used as a raw material for making several products.

Calcined Bauxite: Calcined Bauxite is obtained by calcining (heating) superior grade Bauxite at high temperature (from 850 oC to 1600 oC). This removes moisture thereby increasing the alumina content. Compared to an alumina content of about 57 % to 58 % in raw Bauxite, Calcined Bauxite has an alumina content of 82 % to 86 %. The heating is carried out in rotary kilns. Calcination is done at different temperatures ranging from 850 oC to 1600 oC depending upon the customer’s application. We export Calcined Bauxite for various applications such as refractory bricks, abrasives, steel polishing, etc. We provide consistency in quality and availability of Calcined Bauxite at extremely competitive prices. Applications of Calcined Bauxite: Refractory Grade Calcined Bauxite (CB - I and CB - II Grade) : To make refractory grade, Bauxite is thermally treated at 1600 oC to produce Calcined Bauxite where the Alumina content is mostly above 82%. Brown Fused Alumina, Proppants and Road Surfacing : To make the above grades, Bauxite is thermally treated at 1000 oC - 1200 oC to produce Calcined Bauxite where the Alumina content is anywhere between 80-88% depending on the requirement.

Raw Bauxite: Bauxite is a soft, whitish to reddish-brown rock consisting mainly of alumina-bearing hydroxides, oxides of iron, silicon and titanium with impurities of Ca, Mg, Cr, V, P, Ga and other elements. Raw Bauxite is a major source of aluminium. Basic alumina containing minerals of Bauxites are gibbsite Al(OH)3, Boehmite g-AlO(OH) and Diaspore a-AlO(OH). We are a major Raw Bauxite Exporter based in Maharashtra (India) and catering to the diverse demands of several middle and eastern Asian countries. About Raw Bauxite: The processing of Raw Bauxite is done at a number of alumina refineries in the world. Bauxite can be processed at a low-temperature autoclave digestion (145 oC to 155 oC). Raw Bauxite can be used also for sweetening stage and for non-autoclave digestion in agitators (105 oC). About 85% of bauxite mined worldwide is used to produce alumina for refining into Aluminium metal and the balance 15% is processed and value added to make its way to other uses like refractory, chemical, cement, abrasives, etc. Aluminium is possibly the most versatile product with applications in almost every industry. Since Bauxite is the primary source for Aluminium there will always be an ongoing promising demand for the same. Application & Uses of Bauxite: Raw Bauxite is successfully used for metallurgical grade alumina production besides applications in the cement industry, alumina chemical, steel, alum, energy industries, flame-retardants, etc. Bauxite is used in : - Aluminium - Cement - Chemical - Blast Furnaces - Iron/Steel Ladles, etc. Advantages of Artha Bauxite: Artha Mineral Resources has good sources for Gibbsitic Bauxite which requires low digestion temperature (145 oC -155 oC) making it more economical to process. Mines are also in close proximity to all-weather ports which makes it very convenient and cost effective to ship this material.
