No-shear balers are the most competent to bale large quantities. They use half the horse-power required by shear balers and deliver dense uniform distribution of material throughout the bale.

The HBC line of large, single ram balers from Netherlands-based Bollegraaf Balers and Sorting Systems is making its way into the Canadian market. Until last year — when an office was opened for Van Dyk Baler (Bollegraaf’s North American representative) — the machines were relatively unknown and untested in Canada. (A few were in operation in Ontario in the Region of Durham and at the Guelph Wet/Dry Facility.)

The idea behind this patented technology is relatively simple. Because the baler uses a pre-press flap instead of a gathering ram to properly position the material in the bale chamber, there is no shearing action. This means that the baling ram can literally be put on wheels and the baler never needs to be relined. Traditional single- and double-ram extrusion balers require shearing, so the baling chamber must be relined about every four years. This may cost tens of thousands of dollars and up to a week of downtime.

Another advantage of the pre-press flap concept is speed. Due to the quarter-cylindrical shape of the flap, material can be fed onto the top of the flap while the baling ram runs underneath. This method allows the feed conveyor to run almost continuously and provides for the fastest fibre baling in the industry — up to 30 tonnes per hour of OCC and 70 tonnes of newsprint or high grades.

The machines utilize photo-eyes to accurately judge the amount of material in the chamber, so no operator is required.

An example of the effectiveness of the non-shear machinery comes from one of the many private operators in the U.S. New Jersey-based All-American Recycling was processing 3,000 tonnes of waste each month with a four-year-old two-ram machine. Following the replacement of this unit by a 10-year-old Bollegraaf HBC-100, the company’s electrical costs dropped from $5,000 per month to only $917 per month (annual savings of $50,000). Add to that lower maintenance costs, the elimination of relining and the cost of an operator and the overall annual savings reached almost $100,000.

Toronto, Ontario-based Wasteco also notes the advantages of the equipment. They had to find replacements for equipment lost in a recent fire. After investigating major suppliers, Wasteco purchased a commercial fibre processing line and a large HBC-110 baler.
