Balers are not only important for handling scrap materials, but the right baler is an important profitability factor for businesses that rely on scrap handling systems.
The most common are horizontal closed door balers which can easily handle for 2 to 3 bales an hour as well as open end auto balers which can produce for 2 to 12 bales per hour.
Having said that, most balers have different feed chute sizes that accommodate different bale sizes and are thus accompanied with different size cylinders to work with varying pre-bale density in the baler chute.
For example, a cardboard baler constructed for corrugated waste would not work as well for a tissue baler. Using a baler for corrugated materials or folded carton materials in an open end baler with an 8 inch cylinder works best with a small feed chute, 27.5" x 32" or anything close to this. This is to prevent the baler from stalling out while trying to get into auto tie. Some balers are sold with a 40-inch long feed chute and have issues baling this material due to the product density. The sensors in the baler chute have to be set very low giving the bales loose tops and low bale density. While a 40-inch feed chute can be used for less dense material with a 8-inch line. Copy paper, printers waste and magazine grades will be very well with the 8-inch cylinder and 40 inch feed chute. In order to use a larger feed chute with the denser materials a 10-inch cylinder will better serve your baling needs.
While a baler is in auto tie, the ram is forward and still for 30 seconds. The incoming product must have a place to store above the ram until the baler comes out of auto tie and proceeds to bale again.
The bales themselves on most paper products weigh an average of 900 to 2000 pounds. The bales are purchased from either recyclers or brokers so there is a pay back on this investment. Depending on the quality of the paper, and the type, more money is offered per pound. By getting the best quality and density for your grade of paper will increase your profits.
If an 8-inch cylinder with a smaller feed chute makes a 1500 pound bale compared to the 40-inch feed chute with a 8-inch cylinder may make a 1100 pound bale. The owner will get more paper on one truck and cut down on shipping costs, use less wire for tying, save room for storing and have less material waste fall off the bale on the floor.
