High Capacity Baling of Recyclable Materials
Paper Recycling located in Fort Worth, Texas was using a typical, two-ram
baler to bale approximately 5000-6000 tons per month of recyclable paper.
This process required 6 days a week using 2 shifts. In an effort to be
more efficient, Evergreen began to research different methods to improve
their operation. Their search led them to Sierra International Machinery
and the Macpresse baling equipment. This high capacity single ram baler was
able to process all the monthly tonnage in a single shift, five days per
week. The end result was a reduction of employees with no baler operator
required, fewer bales were handled, significant savings in electrical costs
were achieved, and substantial improvements were realized in equipment
Many advantages were achieved by Evergreen when they upgraded to a high capacity horizontal baler in place of a traditional two-ram baling system. The most obvious advantage was the elimination of a full-time baler operator. All functions of the Sierra high capacity horizontal baler are completely automatic.
Evergreen increased production from an average of 14-16 tons per hour to 25-29 tons per hour for OCC. Re-baled OCC is baled at a rate of 35-39 tons per hour. The bale weights and densities of the Sierra baler are much higher, with OCC bales weighing approximately 2100 pounds. This is a 600-700 pound per bale increase.
Handling larger and heavier bales has resulted in fewer employees required to perform the same amount of work. Wear and tear on fork-lifts and other equipment is noticeably decreased due to handling 25% fewer bales.
Evergreen Paper has received favorable comments from paper mills regarding the dense, square, heavy bales produced by the Sierra system. Now, more tons can be stored in a smaller space. Maximum shipping weights are achieved in export containers and over the road vans.
The monthly electrical bill has decreased by approximately 30%, even though the new baler uses the same amount of horsepower as the older baler. This is achieved by using a more efficient hydraulic system and high efficiency motors.
“ The Macpresse system has consistently performed better than I expected and processes material faster than represented in sales discussions.”
