This machine is with the variable pitch impeller, pulverized coal at the back of the cylinder will be pushed ahead, after compression, through hole of the front of the helicopter is extruded, form coal rods, round hole shape has a lot of kinds. The shape of the coal rods also have a variety of. Coal rods in the process of advance naturally broken by gravity.
The machine adopts machine of decelerate of hard tooth, small size, high bearing capacity. Internal impeller designed by thickening, the impeller and tube liner is wear-resistant and precious casting materials, longer 4-5 times than the ordinary material ; Head of the department of coal rods export is replaceable wear-resistance alloy steel material, easy to change. The head cylinder is hinged form, can open when maintenance, replace the internal impeller and tube line is very convenient.
