Embodiment
As depicted in figs. 1 and 2, a kind of cast waste sand graded crushing device, including graded crushing cylinder 10 and blower unit 20.
Antiquated sand block and waste sand particles are put into the graded crushing cylinder 10, is crushed, sorted.The blower unit 20 is using existing
Technical scheme, realize that wind speed regulates and controls, realize and pneumatic separating is carried out to the material in the range of extra fine quality.
The front end of graded crushing cylinder 10 is provided with hopper 1 and the induced duct 2 connected with the blower unit 20, and end is provided with
Rewinding mouth 3 and dedusting pipeline 4, inside are provided with broken cylinder 5 and sub-sieve cylinder 6.Antiquated sand block and waste sand particles are simultaneously from the hopper 1
Blanking, thus the hopper 1 uses heavy caliber, with suitable for the larger antiquated sand block of volume.The gas that the blower unit 20 blows
Stream is sent into the graded crushing cylinder 10 by the induced duct 2.The rewinding mouth 3 be used to collecting it is broken after meet regeneration particle diameter
It is required that waste sand particles.The dedusting pipeline 4 is discharged with by dust caused by sorting in the graded crushing cylinder 10, described in holding
The waste sand particles quality being collected at rewinding mouth 3, and ensure the security of running environment in the graded crushing cylinder 10.It is described broken
Broken cylinder 5 is mainly used in broken antiquated sand block.The sub-sieve cylinder 6 is used for sub-sieve dust and waste sand particles.
The broken cylinder 5 includes breaker rotor 51, rotating cylinder drive device and some grinding spheroids 52.The knot of broken cylinder 5
Structure and working method are similar to existing ball mill, drive the breaker rotor 51 to be revolved around cylinder axis by rotating cylinder drive device
Turn.The front end of breaker rotor 51 is connected with the hopper 1 and the distal opening of the induced duct 2.By the grinding spheroid 52
Antiquated sand block, the material such as waste sand particles entered by the hopper 1 in the breaker rotor 51 is impacted, ground, rolled.Together
When, the material such as the small waste sand particles of quality, dust is blown to described under the wind-force effect that the induced duct 2 imports in material
The end of breaker rotor 51.
The inwall rule of breaker rotor 51 is laid with some fins.Be advantageous to strengthen the machinery that the materials such as antiquated sand block are subject to
