The sarawak silica powder project malaysia
on the island of borneo in the malaysian state of sarawak a strategic industrial project is processing local silica sand into high-purity powder for the glass and ceramics industries. this is the sarawak silica powder project which features an advanced ball mill stone powder grinding mill with a classification system achieving a capacity of 7.5 tons per hour. the raw material is silica sand sourced from the massive sand deposits along the sarawak river system sand that has been weathered from granite rocks in the interior mountains and transported downstream over millions of years.
this sand is naturally high in silica content but contains impurities like iron oxide that must be removed through magnetic separation and intensive washing before grinding. the ball mill reduces the purified silica sand to a fine powder with a target fineness of 180 microns or approximately 80 mesh. this specific particle size is ideal for the production of container glass and flat glass where uniform melting behavior is essential for product quality. the powder is supplied primarily to glass manufacturers in the kuching and samarahan areas who produce bottles jars and window glass for the sarawak and sabah markets.
The smaller portion of the production is sold to local ceramic tile manufacturers who use the silica powder to adjust the thermal expansion properties of their tile bodies. the project faced the challenge of processing a highly abrasive material that rapidly wears down grinding media and mill liners. the solution was to use high-alumina ceramic linings and grinding media in the ball mill significantly extending maintenance intervals and preventing iron contamination that would discolor the final glass products.
The 7.5 tons per hour output from this stone powder grinding mill represents a major step forward in sarawaks industrial development transforming a plentiful local resource into a high-value manufactured product and creating skilled employment opportunities in this rapidly developing region of malaysia.
