BED MATERIALS AND SILICA SANDS

BAT BED MATERIALS are provided in two kind of products, that are Fire clay bed materials and Crushed refractory brick bed materials. These products are used as bed materials for CFB and CFBC Boilers which need the high temperature in operation.
BAT SILICA SAND are also provided in two kind of products, there are Silica sand which is made from crushed and screened silica stone and silica sand which is made from screened Silica sand. These products are used as bed materials for CFB and CFBC Boilers which do not need the high temperature in operation.
