The powder bag shaping machine greatly increases the output and reduces the operating cost.

The machine integrates crushing and single-function shaping: for different stones and different uses, by changing the feeding mode and core structure of the crushing chamber, the production can be greatly increased and the operating cost can be reduced on the basis of ensuring that the gravel grain shape is up to standard. Central feed: the material falls into the hopper, enters the rotating impeller through the central feed hole to accelerate, and then shoots out from the impeller, first collides with another part of the material that falls freely after bouncing, and then impacts together to the vortex-shaped material lining (stone hitting stone) in the vortex chamber, and is first bounced to the top of the crushing chamber, and then deflected downward. It impinges with the material emitted from the impeller runner to form a continuous material curtain, and finally drains through the lower discharge port. Central feed with ring fall feed: the material falls into the hopper, then falls through the ring hole, and is divided into two strands by the bulk cone. One strand enters the high-speed rotating impeller through the distributor plate, and the other strand falls around the distributor plate. The material entering the impeller is shot out after it is rapidly accelerated in the impeller. First, the other part of the material in free fall around the bulk material cone is impacted and broken, and then the eddy lining in the vortex chamber is impacted together, and it is first bounced to the top of the crushing chamber, and then deflected downward. The material emitted from the impeller runner impinges to form a continuous material curtain and is discharged from the bottom discharge port. Shaping machine can be widely used in highway, railway, hydropower station, bridge, tunnel, concrete mixing station, construction and other industries in the field of gravel shaping and gravel processing. In particular, for the shaping of gravel in concrete with strength grades greater than C60 and in concrete aggregates that are frost resistant, impermeable or otherwise required, as well as for the shaping of continuous grained gravel for highway pavement. It can be directly used as the second breaking equipment of jaw breaking, cone breaking and other equipment, and can be used independently. In the fine breaking equipment is an alternative to the impact crusher. Its main performance index is much better than that of counterattack. Bearing all the load of the machine, so good lubrication has a great relationship to the bearing life, it directly affects the service life and operating rate of the machine, so the injection of lubricating oil must be clean, the seal must be good, the main oil of the machine (1) rotating bearings (2) roll bearings (3) all gears (4) active bearings, sliding plane.
