Introduction alumina aggregate Products: alumina aggregate is after is the result of natural bauxite bauxite calcination kiln, forming agglomerates become high bauxite aggregate guessed, also called refractory bone material, after picking clinker crushing, screening process, you can get the different aggregate size range, AL2O3 content greater than 90% is called the high-alumina aggregate. Uses: High alumina refractory castable aggregate it is indispensable raw materials, it can and alumina cement, fine powder, mixed in proportion to generate a very high strength refractory concrete. Product Specifications: aggregate size standard for 0-1mm, 1-3mm, 3-5mm, 5-10mm, 10-15mm and so on. (Can be the root of all kinds of customer requirements) Yangquan positive element of high quality refractory bauxite plant physical and chemical indicators Grade Chemical composition% of the volume density g / cm absorption% Al2O3 Fe2O3 Ti2O CaO + MgO K2O + Na2O GA1-88 > = 88 <= 1.5 <4.0 <= 0.4 = * = 85 <= 1.8 <4.0 <= 0.4 = 3.10 = 80 <= 2.0 <4.0 <= 0.5 = 2.90 70 - 80 <= 2.0 - <= 0.6 = 2.75 60--70 <= 2.0 - <= 0.6 = 2.65 50 - 60 <= 2.5 - <= 0.6 = 2.45 <= 6 according to user needs, processed into aggregate (0-1,1-3, 3-5,5-8 mm and other specifications), powder (200 mesh, 325 mesh, 400 mesh, etc.) About Us Yangquan positive element Refractories Refractories Co., Ltd. is located in the hometown of the famous - Yangquan. Local rich bauxite, is one of China's largest production base of refractories. Founded in 1995, 16 million yuan in fixed assets, the annual output of 20,000 tons. The company's advanced automated production equipment, gas sintering process and improve the service in the industry counterparts enjoyed a high reputation, and was awarded the units of energy saving pacesetter companies. Our main products are high alumina bricks, high alumina insulating bricks, high alumina semi-insulating bricks, clay, clay insulation bricks, insulation bricks diatomite, perlite insulation tiles and other specifications of various monolithic refractories; castable, ramming unshaped refractories hot fill material, plastic, spray paint, refractory mortar, such as different grades; bauxite (raw material, clinker, aggregates, powder), homogenized material, silica, quartz, feldspar different levels of fire-resistant materials. Enterprise products sold throughout the country and exported to Europe, America, Japan and Korea. We adhere to honesty, quality products, perfect service, cross-world friends.
