PET Bottle & Cans Balers

Post-consumer bottles and cans shift unpredictably during compression, creating severe eccentric loading across the platen. Without rigid mechanical guidance, the piston rod absorbs non-axial bending stresses that score cylinder walls and destroy hydraulic seals. Rumtoo’s twin solid-steel chrome-plated guide pillars absorb all lateral deflection forces, guaranteeing that the platen travels perfectly parallel to the floor throughout every high-tonnage stroke.

Plastic containers possess high elastic memory that causes them to expand upward the moment the press platen retracts. Our chamber walls incorporate three tiers of spring-loaded, hardened serrated steel retaining claws. As the platen presses material downward, the claws depress flush into wall recesses; once the platen passes, they snap forward to wedge compacted containers down, eliminating chamber expansion and halving total reloading cycles.

Crushing beverage bottles and cans releases residual sugary soda, juice dregs, and washing water. Rumtoo vertical balers feature a heavy-gauge SUS304 stainless steel floor sump equipped with perforated filtration screens and a 1.5-inch bottom ball valve. Liquids drain immediately into an external collection line or reservoir, preventing corrosion of structural steel plates and keeping workshop floors clean and dry.

Due to the extreme outward expansion pressure of compressed PET, we recommend using 3.0 mm to 3.5 mm high-tensile galvanized baling wire (minimum tensile strength 1,000–1,200 N/mm²) or 19 mm heavy-duty polyester (PET) strapping with heavy wire buckles. Our platen and chamber floor feature 4 to 5 precision-aligned wire threading grooves that allow operators to knot wires securely while the ram maintains full holding pressure.

Yes. Rumtoo vertical balers are multi-material workhorses. The hydraulic system includes adjustable pressure relief settings: 16–18 MPa for cardboard and paper packaging, and 20–22 MPa for high-elasticity PET bottles, HDPE jugs, and aluminum cans. The reinforced platen faceplate easily withstands sharp metallic edges from cans without puncturing or gouging.

Depending on model size and operator loading speed, the machine completes 6 to 8 compression cycles per finished bale, requiring approximately 10 to 15 minutes per bale including wire tying and ejection. A 50-ton unit typically yields 3 to 4 dense bales per hour (600–1,000 kg/h for PET bottles, or 400–600 kg/h for aluminum UBC cans), translating to 5–8 metric tons per standard 8-hour shift.

We recommend premium anti-wear hydraulic oil ISO VG 46 for temperate indoor environments, or ISO VG 68 for high ambient temperature workshops exceeding 35°C. The system comes equipped with a suction filter and return-line magnetic strainer. The initial oil batch should be inspected and filtered after the first 500 operating hours, with full oil replacement every 2,000 to 3,000 operating hours.

The machine requires a standard 3-phase industrial power supply (380V/415V/460V, 50/60 Hz, 7.5 kW to 22 kW depending on model). It requires no special sub-surface foundation; a level, reinforced concrete floor with minimum 150 mm thickness is sufficient. Overhead ceiling clearance should exceed total machine height by at least 1.0 meter (minimum 3.5 to 4.2 meters clear ceiling height) to accommodate full cylinder stroke extension.
