Method for operating the air circuit and conveying the flow of material in the housing of a hammer crusher and housing of a hammer crusher for carrying out the method

摘要

In order to operate the air circuit and convey the stock flow o fold material crushed in the casing (1) of a hammer mill, the airflow generated by the blast effect of a rotor (2) and the stock flow passing through an upper grading grid (4) are diverted by a deflector hood (8) and guided vertically downwards into a duct (6)delimited by the casing (1), said stock flow being combined with the stock flow graded in the area of a lower grading grid (5). The air flow is then guided to the circuit and the combined stock flow is guided to a device (11) for further processing, sorting and/or conveyance.
