XinXiang GaoFu Machinery Co.,Ltd was founded in 1982, 34 years experience in crushing and vibrating , products were exported to all over the world.GF toothed roll crusher were developed by GF engineers, which mainly used to crush low and medium hardness brittle materials, for example coal, soft coal, gangue, lignite, shale,sinter,slag, the limestone and so on. which dedicated to circulating fluidized bed boiler in thermal power plant.GF toothed roll crusher with four patents and eight characteristics, which composed by rollers which rotate toward each other , material directly falls into for the size in accordance with two teeth roll gap,  exceed the gap’s material are crushed by rollers of splitting, breaking, and striking then falls to meet the granularity’s requirement. Relative roller differential operation can clear up the slot residual materials, all of this avoidance the material’s repeated crushing, without gluing and plugging.
Four patents:
Uniform Fabrics of Vibrating  feeder patent,
Tooth plate patent,
Hydraulic automatic  concession system
Rapid replacement tooth plate patents
Eight characteristics:
