b. Main Equipments: Jaw Crusher, Conveyor, Vibrating screen, Vertical preheater, Rotary kiln, Vertical cooler, etc.

step2:Grinding and balling
a.Process introduction: Using jaw crusher and ferrosilicon crusher to crush and grind ferrosilicon to the size of less than 20mm, then grinding these three kinds of minerals(calcined dolomite,ferrosilicon and fluorite), after grinding, convey them to the briquetter.
b.Main equipment: Electronic batching scale, Bucket elevator, Ball mill, Screw conveyer ,FU chain conveyor, etc.
