Extrac Wam Bag Emptying Equipment
Extrac Wam COM - Waste Bag Compactors

The COM Bag Compactor for torn empty bags consists of a mild steel or 304/316 stainless steel trough with appropriate surface finishing. The U-profile trough is longitudinally split in half to facilitate replacement of the SINT liner that helps introduction and further compression of the broken bags. 

The Bag Compactor is equipped with a suitable direct drive unit. At the drive end the compactor is equipped with an end plate fixed to the end flange of the trough for assembly of the end bearing complete with flanged shaft coupling for the bag compacting screw. The other trough end is connected with a tapered pipe that facilitates the progress of the compacted broken bags. At the end of this steel pipe a polyethylene tube for disposal of the waste bags can be fitted.

The COM Waste Bag Compactor receives entire empty bags or bag fragments from a bag emptying device compacting the bags to approximately one eighth of their original volume. Collected in a polyethylene hose that is periodically cut and closed, the waste bags can be easily disposed of.

Extrac Wam NST - Belt Conveyor

The NST Belt Conveyor is supplied as a bag feeding accessory for RSA-type Automatic Bag Splitters.


The bags are placed on the conveyor belt following the instructions in the Operation & Maintenance Manual of the RSA Automatic Bag Splitter. The design guarantees perfect grip of the bags and an optimum feed position into the RSA inlet.
Performance & Technical Features - Benefits

Installed drive power: 1.1 kW (1.5 HP)
Belt speed: 16.4 m/min (18 yds/min) with 4-pole electric motor at 1,450 r.p.m.
Extrac Wam RSA - Automatic Bag Splitters

The RSA Automatic Bag Splitter is made up of a splitting unit consisting of a trough that encloses an extra-heavy-duty splitting screw complete with an appropriate gear motor and of a screening unit consisting of a horizontal cylindrically shaped rotating screen also complete with a drive unit. 

On top of the screening unit a suitable fan-operated dust collector can be integrated. Alternatively the RSA is supplied with connecting spigots for a central de-dusting unit.

The RSA Automatic Bag Splitter is used for splitting and emptying of single or multiple layer bags made from paper, polyethylene, polyethylene-lined paper, interwoven plastic, or polyethylene-lined interwoven plastic.
The bags are loaded manually or via belt conveyor into the inlet which is covered by a dust collecting hood. The bags drop from the belt on an extra-heavy-duty shaftless screw. Thin bags will burst open just through the impact. Bags with multiple layers or those made of elastic plastic material are pulled in by the slowly turning screw and ripped open through a scissor effect between screw and trough. This effect is increased due to a replaceable panel with integrated cutters applied to the inside of the trough. As it cuts them open the screw conveys the broken bags and their content into the revolving screen. Interwoven plastic bags are cut open by a multiple cutting disc kit mounted on top of the inlet port. The bag contents fall through the screen mesh into a collecting device mounted on the outlet of the machine. Through rotation and a slight vibration of the screen (due to its patented design) the bags are completely emptied. Paddles applied inside the screen drum repeatedly lift up the empty bags. In this manner the bags are liberated from remaining material. The inclination of the paddles helps the bags move towards the screen outlet where they drop into the built-on COM-type bag compactor (see COM).

Extrac Wam RSM - Manual Bag Emptiers

The RSM Manual Bag Opener consists of a grille with a rest fitted to its front, The grille is mounted on top of a hopper which is supported by four feet. A fabricated hood with protection door fitted to its front covers the hopper and grille. 

RSM Bag Openers are manufactured in high-finish-grade materials and come with or without integrated de-dusting filter unit. In the version with integrated dust filter the filter elements are cleaned pneumatically by reverse air jet.

The operator puts the bag on the rest and pushes it on to the grille. He then slits the bag open with a vertical cut and shakes it empty. While the bag content may be discharged through a hopper or by BINSWEEP, a special rotary discharging device, into any type of feeder, the built-in fan operated, air jet cleaned dust collector filters the dust generated during emptying. The empty bag is dropped in the chute on the side which leads into the optional COM-type Waste Bag Compactor (see COM).
Manual RSM Bag Openers are designed to minimize material residue. They are suitable for numerous customizations and satisfy a large number of applications due to their modular component design.

Performance & Technical Features - Benefits

Construction material: Carbon steel, 304 L / 316 L stainless steel
