Powder bag shaping machine can be widely used in expressway, railway, hydropower station, bridge, tunnel, concrete mixing station, construction and other industries in the field of gravel shaping and gravel processing. Especially for concrete with strength grade greater than C60 and concrete aggregate with frost resistance, impermeability or other requirements in the shaping of gravel and expressway pavement with continuous gravel shaping. It can be directly used as the second breaking equipment of jaw breaking, cone breaking and other equipment, and can be used independently for shaping. In the fine breaking equipment is an alternative to the impact crusher. Its main performance index is much better than counterattack.
The center feeding of powder bag shaping machine is accompanied by annular waterfall feeding: the material falls into the hopper, and then falls through the annular hole, and is divided into two pieces by the bulk cone. One enters the high-speed rotating impeller through the sorting plate, and the other falls from around the sorting plate. Into the impeller material, after the impeller is rapidly accelerating injection, first with the powder cone free fall impact crushing another part of the material, and then hit with eddy current eddy current on the lining cavity, be rebound to the top of the crushing cavity, deflecting downward movement, after impeller passage emitted material impact to form a continuous material curtain, and finally by the lower discharging mouth eduction.
Powder bag plastic machine bearings for machine full load, so good lubrication for the bearing life has a lot to do, it directly affects the service life of machine and availability, and requirements into lubricating oil must be clean and seal must be good, the machine's main oil (1) the rotation bearing (2) roll bearing (3) all the gear bearing, sliding plane (4) activities.
