Two-ram balers

Fully automatic two-ram horizontal balers for medium-sized and large recycling operations

A two-ram baler is a type of horizontal baler where the main ram compresses material against a steel wall, and the eject ram ejects finished bales through an automatic bale tying system. This allows for a continuous process.

Two-ram balers from Sierra are ideal for baling large volumes of aluminum, extrusions, tin cans, stainless steel, copper, radiators, OCC, plastics (PET, HDPE, LDPE, PP), aluminum siding, insulated and stripped copper wire, and municipal solid waste (MSW).
