First stage: limestone chunks are transported by special vehicles to raw materials bin, after the forklift / artificial then delivered to the jaw crusher for crushing by forklift or man. Second stage: Crushed limestone is lift to the hopper by hoist, then transported by feeder. Third stage: Qualified products after the grinding process enter the collector through classifier and pipe. The discharged powder is finished product. Unqualified powder cannot pass the classifier, and falls back to the main unit. Fourth stage: The purified air stream flows into the blower through pipe above the collector. The air duct is circular, it is negative pressure pipe flow, except for the grinding chamber and blower, so indoor air conditions are good.
