Hammer Mill Hard Drive Shredder

A hammer mill specifically designed for for Hard Drive Shredder in the eScraping electronic scrap recycling business.

No matter what your electronic scrap recycling application, you can count on extraordinary performance. The robust design of the EScraper Hard Drive Shredder – with its specially designed grinding rotor – is not only engineered to be more efficient, but it also features the longest-lasting, most durable components available. That means you spend less time performing maintenance, and more time processing and recycling.
No other hammer mill destroys computer and electronic components better than our Hard Drive Shredder. In today’s digital world, protecting proprietary information requires extra measures throughout the business cycle. The EScraper is an important tool in the security process giving you added confidence that your confidential information never ends up in the wrong hands.

  • Unlike most shredder, which tends to create long strips of e-waste, the EScraper passes material through a small screen or grate.
  • The powerful and turbulent action within the mill renders the electronic components virtually unrecognizable and certainly unusable.
  • Scrap enters the steel grinding chamber and is attacked by a series of steel hammers that crush, rip, and shred the material into small pieces
  • At the same time, the material is being reduced in size, it is also scraped and scoured, rendering any remaining information on the components illegible.
  • Typical applications include the destruction of printed circuit boards (PCBs), lead frames, ICs, and ink wafers
  • Computer hard drives are completely shredded and destroyed thus eliminating the ability to retrieve any remaining embedded data. The average hard drive is reduced to pieces that are less than 3/4″ (19mm) after passing through the hammer mill. Secondary processes can reduce these pieces to an even finer grind.

How to Profit from Precious Metals Recycling

No other Hard Drive Shredder is more valuable for the effective and profitable recycling of precious metals from electronic components than our hammer mill. The hammering action not only reduces, but it also liberates various materials on populated components such as PCBs. These materials can then be identified and segregated downstream by other processing equipment. The precious metals recovered can be resold for a profit, which means less waste going into landfills.

WA-Series model WA-8-H “E-Cycler” hammer mill. The 10-horsepower model WA-8-H is a versatile and configurable industrial hammermill. It is constructed of 3/8″ thick carbon/AR or 304/316 stainless steel plate and reinforced by additional 3/8″ thick abrasion resistant wear plates positioned throughout the interior of the grinding chamber. Four-way reversible, 3/8”, ½” or knife edge hammers are made from AR400 steel for long wear life. The main mill shaft is warranted against breakage for 5 full years! Attached please find our quotation, including literature and dimensional drawings.

For particle sizing, we offer many different interchangeable perforated screens, heavy-duty perforated screens, heavy-duty bar grates, and heavy-duty slotted grate sizes. The grates are not only interchangeable but also different combinations of sizes and types of screens may be used to meet the operator’s requirements.

In addition to the interchangeable grate sizes, hammer tip speed / RPM is also important to dial into your specific application. Since the WA Series Industrial Hammermills are V-belt driven, we determine the hammer rotor speed set by the sheave sizes. In this case, we can set the mill to a moderate to slow speed in order to separate the material components without over-pulverizing. The VFD (Variable Frequency Drive) allows you to further control the speed of the hammer mill rotor. With the VFD, you can increase or decrease the set sheave speed. Faster mill speed will result in finer particle size and vice versa.

Optional items such as the infeed chute, discharge chute, support stand, and feeder hopper/conveyor, are always custom-designed and manufactured to your specifications. We will provide you with drawings (based upon your input) for your review. You may accept or modify these drawings as required, and we do not begin fabrication of these items until you have approved and signed off on their design.
