Profile: HuaMing Alumina Technology Ltd. is a manufacturer and exporter of alumina, alumina grinding, inert alumina & perforated ceramic balls, alumina brick & refractory ceramic. We are an ISO 9001:2000 certified company. Ceramic grinding ball of high alumina content is high-density and ultra-high fired; and it enjoys the advantage of high mechanical strength & great wear-resistance. It is an economical, widely-used and non-metallic grinding media. Alumina grinding media ball is mainly used in the ceramics industry, pigment, fine chemical, glass, glaze and many other fields. Inert alumina ball is widely used in petrochemical, chemical, fertilizer, natural gas and environment protection, with functions as covering & supporting materials for catalyst in reactors & packing for towers. The main role of inert alumina ball is to increase the distribution of liquid and gas, to hold & protect the activated catalyst with low strength. Alumina brick is made from high purity refractory clays and other raw materials, with light weight & mini-porosity well distributed. Each brick is machined to precise tolerances on all six faces. It has low thermal conductivity, low heat storage, high hot compressive strength, low iron oxide and alkali flux content & accurate dimensions. Our products are exported to various countries worldwide.
