Melt filter from BritAS increases surface area for greater output
ABMF-1600: BritAS Recycling-Anlagen GmbH, Hanau, Germany, has expanded its line of Automated Belt Melt Filters (ABMF) with this version, boasting 1,600 square centimeters, or about 248 square inches, of surface area. The company’s filters are used for recycling postconsumer and postindustrial plastic, as well as for agricultural film.
What’s new? The filter size. The ABMF-1600 has 50 percent more surface area than the ABMF-1050, which has a surface area of 1050 square centimeters, making it the next biggest filter in BritAS’ portfolio. To accommodate the size increase and to improve melt flow, BritAS also has optimized the inner workings of the screen compared with its other ABMFs.
Benefits: Increased output. With its larger size, the filter can process more material and greater contamination; it is ideal for separating paper contaminants from postconsumer materials.

Presona baler press comes with two motor options
LP 50 EH: The newest baler press from Presona AB, Tomelilla, Sweden, is designed to handle a variety of materials, including plastic film and PET bottles. Available with two motor options—22 or 37 kilowatts—the machine has an eccentric tying unit that ties the wire vertically rather than horizontally to better hold the layers of the bale together. It also is equipped with a wire puller that ensures the knots are positioned at the front and rear side of the bale, where expansion forces are the lowest. Presona is represented in the U.S. by Stadler America LLC.
What’s new? The press, which Presona introduced in December.
Benefits: Better bales, increased productivity, programmability and cost savings. Because it ties vertically, the LP 50 EH produces bales with better density and less spillage, and its hydraulic main press requires minimal downtime. In addition, each unit is equipped with the 50 programmable logic controller (PLC), which includes a 7-inch color touch screen and the ability to create up to 15 baling programs. The PLC allows users to set the ideal number of twists in the wire for a particular material, creating the most durable band bale possible while using the minimum amount of wire.
SatrindTech drive system increases torque, reduces speed SatrindTech drive system increases torque, reduces speed
M/AWG drive system: SatrindTech Srl, Arluno, Italy, has introduced a new drive system for its K-series 50-horsepower shredders. When shredders encounter tough materials, they often need to stop and reverse the conveyor to prevent mechanical damage, backing the material out and changing its position for another attempt. When shredders that are equipped with the M/AWG drive encounter tough materials, however, they pause long enough to reduce speed and increase torque to continue shredding without reversing the conveyor. SatrindTech is represented in the United States by Alan Ross Machinery.
What’s new? The drive system, which was launched in November.
Benefits: Space savings and higher production. The drive system makes the shredder all electric, eliminating the need for hydraulic power packs and reducing the machine’s maintenance costs and space requirements. In addition, production increases by about 30 percent because the unit rarely needs to reverse when it gets stuck.
EnStyro upgrades shredder designed for chopping mattresses
Model 517: Designed for tearing through flexible urethane foams, as well as through expanded PS and PE foams, EnStyro’s shredders can produce particles small enough to pass through 0.125-inch screens. Unlike other shredders, the machine does not compact the material. This method of ripping rather than shearing achieves particles with shape and surface variations and the lowest possible density. The newest version, the Model 517, features a three-phase, 5-horsepower motor for handling tough materials, including 6-inch-thick chunks of foam mattresses. It stands 55 inches high, with a width of 31.5 inches and a depth of 50 inches. The shredder’s chute measures 10 inches wide by 8 inches high. It features a removable screen with sizes that range from 0.125 inch to 2 inches.
What’s new? The power upgrade. EnStyro previously offered only 3-horsepower shredders.
Benefits: Robust handling of tough materials.
Split-A-Part shredder features smaller rotor size
30-inch Eagle shredder: Republic Machine has expanded its portfolio of shredders that feature the Split-A-Part option. Each of the Eagle shredders has a single-piece, solid, forged rotor and reversible counterknives that can be resharpened. An open-architecture Allen-Bradley programmable logic controller (PLC) and an over-torque-limiting clutch, which protects the drivetrain, also are included. Options include replaceable cutting tool holders and customizable control systems for infeed conveyors and outfeed devices. A bigger version of the Eagle shredder, with a 54-inch rotor, is shown at right.
What’s new? The rotor size. At 30 inches wide, the rotor is the smallest of the Eagle offerings, which previously were offered in sizes ranging from 42 inches to 78 inches. The model represents an upgrade over Republic’s comparably sized Falcon shredders, which do not come in Split-A-Part versions. Designed specifically for a hose manufacturer, the first of the 30-inch Eagle shredders shipped several months ago. It featured a 50-horsepower motor; depending on the application, units of the same size also can run on 30-horsepower motors.
Benefits: Easier access for cleaning and maintenance. The Split-A-Part option allows users easier access to the shredder. Operators of a Split-A-Part Eagle can enter the machine without climbing inside of it, a procedure that requires a confined-space permit in some areas.
