Taskmaster® Shredders Handle
E-Waste with Ease

Glencore, a multinational trading and mining company, has a considerable electronics waste (e-waste) recycling and reclaiming business. The company undertakes e-waste shredding and processes all types of e-waste from the smallest electronic components such as flash cards and circuit boards, to the largest such as mainframe computers - and everything in between. The company doesn’t scrap for security or due to bad equipment, but rather for recycling and to reclaim metals such as silver, gold, and copper found within the components and easily reclaimed after the shredding process.

The company processes an incredible volume of e-waste, shredding around 12,000 metric tons per year. They run a one-line system which is at work shredding 24 hours a day, 7 days a week.

Getting the component output down to a specific size is very important for their operation. In order to extract any remaining metals after shredding, the e-waste must go through a multi-stage size reduction sequence to get down to the required output size.

Glencore wasn’t satisfied with the 4-shaft shredders they were using and were looking for a better solution. They were taking too much time to repair, repair costs were excessive and cleaning was required between every production lot, resulting in far too much overall effort, money, and time. The solution was the installation of four TASKMASTER® ELECTRONIC WASTE SHREDDERS.

Glencore purchased four Franklin Miller TASKMASTER Shredders to address vital stages of their shredding process. They have two multi-stage size reduction lines running simultaneously, and are operating a TASKMASTER TM3000 and a TASKMASTER TM1600 in each line. The e-waste first goes through the larger shredder, a TM3000 with fine-tooth, multi-tooth cutters.

“The TASKMASTER 3000 is our first step of shredding for our e-waste line,” said Francois Candela, Technical Engineer at Glencore.

The TASKMASTER® TM3000 is a heavy-duty industrial shredder designed to reduce a high volume of solids with its low speed, high torque design. This twin-shaft shredder is suitable for a variety of shredding applications that demand high power, large throat openings and extra heavy-duty construction. The design of this unit provides effective operation with low noise, sparking, dust or heat rise. It has such heavy construction features as 5.5″ heat-treated alloy steel hexagonal shafting, 2″ cam cutters, heavy steel plate and channel body construction and planetary gear drive. The unit can rip, tear and shred through a variety of tough solids, reducing the volume for further processing or economical disposal.

After the e-waste is processed by the TM3000, the material next goes through a Franklin Miller TASKMASTER TM1600. This machine has ½ and 5/16 multi-tooth fine-tooth cutters. The TASKMASTER TM1600 industrial shredder is a powerful workhorse that can shred heavy solids in both gravity and liquid systems. The TM1600 industrial shredder features a fully sealed body housing with 2-3/4″ hardened hex shafting, mechanical seals and direct inline or optional right angle gear drive. Options include: stainless steel construction, enclosed hopper, flange adapters, channel frames, infeed conveyor, discharge washer or compactor, hydraulic drive, space saving right-angle gear drive and more. This unit can be installed horizontally with a stand, or vertically with a hopper for channel or pipeline applications with flange adapters.

“Once the Franklin Miller shredders have reduced the e-waste to a uniform ½ inch output size, it’s time for the material to continue through the size reduction process,” Candela said.

At this point in the process, the material is further refined through additional size reduction equipment to get to a dust consistency, at which point the material is transferred to a lab to see what metals can be salvaged.Franklin Miller TASKMASTER Shredders help make this e-waste operation a success.
