Shred-Tech, providers of heavy-duty shredders to the waste and recycling industry, introduce what the company describes as a revolutionary design in its redesigned ST-100.
This model offers cutting chamber sizes of 60.5 x 32 inches and 45 x 32 inches, suitable for loading bulky wastes. Bulkheads eliminate the migration of debris into seals and bearings, which thus increases overall shredder durability. The drive system is offered in both hydraulic and electric gear-reduced motors (the redesigned system offers one 75 hp or 100 hp motor). The hydraulic model has optional 100 and 150 hp power units. Internal gear reduction provides maximum transfer of power from the motor to the cutting chamber for optimum efficiency.
Shred-Tech engineers design each knife profile and configuration specific to each application for maximum throughput and optimum shred size. The control panel features illuminated function buttons, keyed power switch, fused lockable disconnect, hour metre and programmable logic controller for shredder functions (including knife reversal on overload). The stand and hopper are extra heavy duty, and there’s an option to modify the stand and hopper to suit specific applications or installations.
The unique design of the machined hex shafts maximizes knife placement options and allows for easy knife removal and machine maintenance. Size for size the hex shaft is several times stronger than a keyed shaft. The hex shaft drive system offers the highest knife tip force of any equivalent shredder on the market. Also, several design refinements incorporated into the ST-100 shredder increase ease of maintenance and shredder durability. Bulkhead walls at either end of the cutting chamber provide excellent bearing and seal protection. The modular construction facilitates quick and easy assembly.

Tarp deployment system
Southwestern Sales Company has announced it has acquired Mercer Motor Works and the patented Tarp Deployment System. The company will move manufacturing of the product line to its factory in Rogers, Arkansas. The acquisition brings together two industry-leading solutions to more safely and efficiently deploy landfill alternate daily cover.
“For several years, landfill operators searched for a safe, reliable and cost-effective solution for spreading alternate daily cover tarps,” states Gerald Barrett, tarpARMOR sales and marketing manager. “We initially responded to the end user’s concerns with existing automated tarp designs and continued developing the system until we arrived at a complete solution for landfill operators.”
Listening to customer’s concerns about their need to reduce equipment maintenance and increase tarp life and coverage, company engineers developed the tarpLOXTM system, a patent-pending solution to securely connect lateral ballast cables to side support chains. The result is a tarp system that maintains a taut 40 ft. wide tarp without bunching even in the most severe environmental conditions.
The TDS tarp deployment system allows one operator to lay up to 12,000 square feet of tarp in less than 10 minutes from the comfort of the cab of existing landfill equipment. Two models are available, the TDS-30 and the TDS-30 HC. The smaller model, the TDS-30, deploys three 6.5 ounce per square yard tarps and weighs in at 3,000 lbs. It is applicable for landfills that have high sludge content, muddy conditions, or otherwise require the use of low ground pressure vehicles. Made with a frame of heavy gauge steel, it has wide foot pads directly welded to the frame. The heavier TDS-30 HC weighs 4,000 lbs and can deploy up to four 9.4 oz per square yard tarps that are 30 x 100 ft. for total coverage of up to 12,000 square feet.

Paintable shaft collars
A full line of paintable steel shaft collars that let manufacturers and maintenance departments precisely match OEM colours has been introduced by Stafford Manufacturing Corp. of Wilmington, Massachusetts. Stafford Paintable Shaft Collars are machined from steel and phosphate coated; preparing them to be painted. Permitting complete machinery and equipment colour matching, they come in 1- and 2-piece clamp-type styles in over 30 standard sizes from 1/8″ to 6″ I.D. and specials up to 16″ I.D.
Available with round, square, and threaded bores, the shaft collars can be customized with face and O.D. treatments such as holes, flats, and knurls. Power transmission and structural applications include actuators, stops, spacers, and component or device mounting. The collars are priced according to style, size, and custom design requirements. Samples are pricing are available upon request.

Fine particle reclamation
The Eriez® FinesSortTM Metal Recovery System (MRS) utilizes a series of powerful magnetic components to process discarded “fines” material that has passed through the initial screening stage to recover valuable ferrous and nonferrous metals. FinesSort MRS not only reduces the amount of waste destined for landfill, but also reclaims thousands of pounds of metals per day.
“This System is a perfect solution for any scrap yard operators looking to be more environmentally-friendly and profitable,” said Mike Shattuck, Eriez Heavy Industry Project Manager. According to Shattuck, FinesSort offers payback on investment in as little as six months.
Shattuck explains, “Scrap yard operators often only focus on reclaiming larger sized nonferrous metals, ignoring smaller material referred to as ‘fines’ which represents roughly 15 percent of the original total flow.” He continues, “When you consider that within the fines, generally less than five percent is recyclable metal, the stream may seem insignificant. However, reclaiming these valuable metals can be worth hundreds of thousands of dollars annually!”
FinesSort MRS is available in 60-inch widths which can typically process ~15 tph. of fines. Each machine is built of heavy gage steel and assembled on a rugged steel framework.
Material is presented to the ferrous separation portion of the machine where a series of magnetic separators recover any ferrous present in the material stream. The initial separation consists of a Rare Earth Dynamic Head Pulley where weakly magnetic material is removed from the material stream. This ferrous material is presented to a Cleanup Drum where saleable ferrous is removed, cleaned and conveyed to a collection bin. Magnetic debris is delivered to a waste conveyor.
Nonferrous materials are presented to a High Frequency Eddy Current to recover smaller pieces of nonferrous metals. Recovered nonferrous metals are conveyed to a collection bin. Recovery and grade of nonferrous metals is typically +90 percent. Nonferrous debris is delivered to a waste conveyor.
