Abstract
A system for processing a powder material like e.g. a friction material, including a weighting device for the powder material and an extruder to feed the powder material to a lump breaker device arranged immediately downstream the extruder to let a completely pulverized material to fall into a hopper arranged over the weighting device the lump breaker device including a rotating drum arranged transversely the extruder and delimited by a lateral surface provided with a plurality of depressions preferably spoon-like, on the whole extension thereof; the lateral surface being arranged immediately adjacent an outlet end of the extruder and being rotated toward the outlet end from upside down.
Claims12
A system for processing a powder material, the powder material consisting in a friction material or a friction material mixture for production of a friction material block for brake elements, or a mixture for production of an underlayer for brake elements, the brake elements being brake pads or brake shoes, the system comprising:
- a weighting device configured to receive and weight onto a collecting element thereof a predetermined quantity of the powder material;
- a feeding device configured to cause a flow of said powder material towards the collecting element of the weighting device;
- a control unit configured to stop the feeding device in response to a signal generated by the weighting device when the collecting element thereof receives said predetermined quantity or is close to receiving said predetermined quantity;
- and
- a rotating device interposed between the feeding device and the collecting element to intercept lumps present in the flow of said powder material;
- wherein said rotating device consists of a lump breaker device arranged immediately downstream the feeding device, with reference to a moving direction of said flow of powder material, the lump breaker device comprising:
- i) a rotating drum arranged in front of an outlet end of the feeding device and adjacent thereto, in order to intercept an entirety of the flow of powder material, the feeding device being configured to cause the entire flow of powder material to hit a lateral surface of the drum;
- ii) a motor arranged on one side of the drum and configured to rotate the drum towards the outlet end of the feeding device upside down;
- iii) a plurality of depressions arranged on a whole extension of the lateral surface of the drum;
- and
- iv) an L-shaped shield arranged along a rotation axis of the drum at a first longitudinal side of the drum and adjacent to the lateral surface of the drum, the L-shaped shield being arranged with a lower end thereof at least in part beneath the drum.
A lump breaker device for processing a powder material consisting of a friction material or friction material mixture for production of a friction material block for brake elements, including brake pads or brake shoes, or a mixture for production of an underlayer thereof, the lump breaker device comprising:
- i) a rotating drum configured to be arranged in use in front of an outlet end of an extrusion device for the powder material, the drum being delimited by a lateral surface thereof configured to be hit in use by the powdered material;
- ii) a motor arranged on one side of the drum and configured to rotate the drum around a rotation axis thereof arranged substantially horizontal, the motor being configured to rotate the drum in a direction such as the lateral surface of the drum crosses in use the outlet end of the extrusion device from upside down;
- iii) a plurality of depressions arranged evenly on the lateral surface of the drum for the whole extension thereof;
- and
- iv) an L-shaped shield arranged along a rotation axis of the drum at a first longitudinal side of the drum and adjacent to the lateral surface of the drum, the L-shaped shield being arranged with a lower end thereof at least in part beneath the drum.
