Abstract
A control method of a crusher for elements to be recycled or disposed of, which includes a crushing assembly, to which the elements to be recycled or disposed of are provided, and pushers acting toward the crushing assembly to push the elements to be recycled or disposed of, includes a measuring step of the current absorbed by the crusher, a comparing step of the current value measured against a first predetermined value, and a reducing step of the push intensity of one or more of the pushers toward the crushing assembly in case the measured current exceeds the first predetermined value, the pushers being controlled separately from each other in order to partialize the push force and the push areas.
Claims10
A control method of a crusher (1) for elements to be recycled or disposed of, comprising:
- at least one crushing assembly (3) to which the elements to be recycled or disposed of are provided;
- and
- two or more pushers (20) acting towards said crushing assembly (3) to push the elements to be recycled or disposed of against said crushing assembly (3),
- said method comprising:
- a measuring step of current absorbed by said crusher (1);
- a comparing step of a value of said measured current against a first predetermined value;
- and
- a reducing step of push intensity of said two or more pushers (20) towards said crushing assembly (3) if said value of said measured current exceeds said first predetermined value, said two or more pushers (20) being controlled separately from each other in order to partialize a push force and push areas.
A crusher for elements to be recycled or disposed of, comprising:
- a crushing chamber (2), in which the elements to be recycled or disposed of are crushed;
- at least one crushing assembly (3) inserted in said crushing chamber(2) and adapted to crush the elements to be recycled or disposed of;
- at least one channel (14) adapted to convey the elements to be recycled or disposed of towards said crushing assembly (3);
- two or more pushers (20) acting in said conveying channel (14) towards said crushing assembly (3) to push the elements to be recycled or disposed of against said crushing assembly (3);
- at least one amperometric sensor (22) adapted to detect a current absorbed by said crusher (1);
- and
- at least one control circuit (23) operatively connected to said amperometric sensor (22) and at least to said pushers (20) to decrease push intensity if a current measurement value is greater than a first predetermined value, said pushers (20) being controlled by said control circuit (23) separately from each other in order to partialize push force and push areas.
