The system installed at Weyerhaeuser Company in Kingsport, Tennessee is designed to handle trim and various types of waste paper, which is produced by the process of making copy paper on a 10-pocket sheeter. There is continuous edge trim; three (3) dust manifolds, one (1) punch manifold and three (3) ream reject gates.

The trim fan is designed to chop twelve (12) ribbons of 1" trim and convey same into an auto-ty baler, which also receives waste from a Corelink stripper. The Corelink stripper automatically removes the paper lift on the core of the roll. The roll is 86" wide and will peel the paper off in access of 500 FPM. This paper waste is conveyed to a Material Discharge Unit (MDU), which separates the paper from the product. The MDU is 6'-7" tall and is very compact. The air is filtered behind the MDU and the dust is deposited into the baler. The air is cleaned to an efficiency of 99.999% to one (1) micron. The air exits out the back of the MDU and into the plant. The reject reams from two (2) packaging lines and the reject hopper is conveyed to a second baler. The dust hoods from the sheeter are tied together and have a dust-handling fan conveying the dust into a high efficiency filter. Compressed air is used to pulsate the filter media, which deposits the dust into a 55-gallon drum. This filter is shared with a second fan system that handles the punches from the sheeter. The punches are conveyed to a high efficiency cyclone with a rotary valve under it. The punches are deposited into a Gaylord container. This system is designed to run continuously without stopping to empty drums or Gaylords. There is no baler personnel in the plant, the operator on the sheeter picks up the bales.

Recently, this plant broke the world production record for thirty (30) straight days of 460 tons of finished product per day. Shortly after this record the plant had a one (1) day record of over 533.7 tons in one day.

Note:

It pays to purchase the right equipment designed to handle the worse case scenario. Conveying paper to a baler cannot be sized per hour, but must be designed per second.

 

At ASDI, we have never installed the same system twice.
Each one is customized to suit the customers' needs.
