RAHA Gilsonite Company owns a plant located in Kermanshah with the full automatic progressive machinery for processing and packaging Gilsonite (Natural Bitumen or Natural Asphalt) in 3 separate production lines. Hence we have the honor to render our high services to our valued customers.
Gilsonite Micronized production line
The company is taking advantage of experts who are capable of processing Gilsonite lump to alter them to powder with the size 80 to 400 mesh and packing according to customer’s order.
Gilsonite is a Soft Rock, meaning that it can be simply made into Gilsonite Powder. A 200m2 industrial unit is sufficient to set up a grinding mill, while complementary packaging equipment is also necessary to wrap Gilsonite into different packaging, from 1 MT jumbo bags to 25 kg worker bags.
The technology of grinding minerals is a vast and advanced expertise which has been developed in different countries. The tricky part of Gilsonite pulverizing is about one of its principal characteristics, i.e. having BITUMEN CONTENT inside. As applying energy into natural bitumen releases the bitumen content, therefore taking the rock asphalt under grinding, makes it a sticky powder, especially if the temperature is not properly controlled during the process.
Depending on the method of grinding, Gilsonite can be made in different mesh sizes, starting from 30 to 400 for Simple crushing machinery. Mesh size goes up to 500 – 1000 Mesh in case a Fusion unit is added.
Still many claim to supply a 3,000 Mesh Gilsonite Product which is a myth, considering there is no economical way to measure such dust particle size.
Another challenge is the environmental hazard. Pollution resulting from grinding the natural bitumen can end up into stopping the facility from production by the authorities in many countries. Still, There are primitive (using back filters) and advanced ways (using output Catalysts) to rectify the issue.
