Packaging & Delivery

Specifications

A brasives industry, refractory materials 
Abrasive cutting tools, moulds, bulletproof material 
To make mechanical parts. 

Descriptions

Brown fused alumina number sand is made of bauxite, scrap iron and anthracite smelted in electric arc furnace at more than 2000 centigrade high temperature. Then, it was crushed by autogenous mill, removed the iron through magnetic separation, screened to variety granularity. It has dense character and high hardness. The particle shape is globular. It is applicable to manufacture ceramics, resinoid high bonded abrasive tools, grinding abrasive, polishing materials, sand blasting and precision casting. It is also used to manufacture high grade refractory.

Features

The product  of our factory has high purity, dense texture, high bulk density, self-sharpening, good toughness, ultra-low magnetic content characteristics, abrasive grinding it made a sharp, low fever, grinding ratio, and the use of less buildup; made of sintered abrasive with dark blue color after firing, can not afford to mesh cracks, no rust, suitable for the manufacture of ceramic, resin and high abrasive grinding, polishing, etc. .

Applications:

It is suitable for grinding high tensile strength of metal, such as a variety of general-purpose steel, malleable iron and hard bronze. It can also create advanced refractories.The ideal material of coated abrasives and resinous grinding wheels;It is functionality filler,filter medium,hydraulic cutting medium,and perfect choice of refractory.For Free grinding, such as glass industry.For Friction products and abrasion resistance ground.For Resin or ceramic bonded abrasive,such as grinding wheels,cutting off wheels..For Refractory Raw material, Wear-resistant and fire-proof products.For Grinding and polishing ,such as gringing stone, Grinding block, flap disc.For Coated abrasives,such as abrasive paper,abrasive cloth,abrasive belt.For Producing mold of precision casting and Grinding, lapping and polishing media.
