1.In a collection apparatus for collecting scrap metal and for compensating depositors for a first type of metal as a function of the weight of the first type of metal deposited in a storage compartment of the apparatus, said apparatus having an input hopper, a start button, a first conveyor for conveying scrap metal from the hopper to a classifier, said classifier segregating a second type of metal from the firsttype, depositing the second type of metal in a metal receptacle and for depositing the first type of metal in a classifier conveyor, said classifier conveyor transporting the first type of metal to and loading said metal into a crusher, said crushercrushing the first type of metal and loading it into a weigher bucket of a weigher which measures the weight of the weigher bucket and its contents, said bucket having a door which is controlled by a scale dump solenoid for emptying the bucket afterweighing, a stacker for conveying the first type of metal after it has been weighed to a storage compartment, an alarm display and means for producing motor alarms, second type metal alarms, classifier jam alarms and dispenser alarms.

The improvements can comprise:
1.a digital electronic controller responsive to a signal from the start button for energizing the first conveyor, the classifier, the crusher and the stacker, for calibrating the weigher, for weighing materials dumped in the bucket of the weigher,for monitoring the bucket to assure that the scale dump solenoid has opened the door thereto
2.a communication port for conveying and receiving remote information.
3.front panel display means for indicating the weight of said first type of metal deposited.
4.The collection apparatus contains memory means for controlling said compensation and the rate thereof.
5.The controller can include short circuit protection means.
6.The first type of metal can be aluminum.
7.The second type of metal can be ferro-magnetic
