75 containing aluminum bauxite 200 mesh powder 600 yuan per ton ex-factory price _ _ bauxite bauxite supplier

I plant the production of 200,325 head high aluminum powder, aluminum content 65,70,75,80. It is bauxite bauxite through 1500 degree high temperature firing into mature material (massive) breaking ball after bagging system complete processing bauxite mesh reinforcement layer is too thin to be difficult in some 200 mesh is appropriate precision casting using a common quartz powder will affect the air permeability prone type casting porosity, ordinary quartz powder density is not easy to harden low winter temperatures have actually hardened impermeable casting pit or collapse easily pumping iron, also known as shell-forming drain running fire. Bauxite make up the shortage of cash common quartz powder, bauxite which contain aluminum oxide, after high temperature will burn the shell of aluminum oxide and aluminous sand stick tightly together to form a binding layer ensures that the overall strength of the shell , do not run the fire. Bauxite breathable quartz powder which is particularly good six times, casting porosity does not appear in normal circumstances. Bauxite light volume 1 cubic = 1.1 tons, (and high aluminum cubic = 1.5 tons) will reduce the volume of light intensity workers. Bauxite viscosity easy to stick sand, sand distribution, Bo Hou uniform shell. Bauxite does not precipitate, two days after a stirring material can also be used. Bauxite is the lost wax casting Shell with the material of choice. Contact: Mr. Wang Tel 18762659702
