Metal Shredder Hammer Manufacturer

When it comes to shredder hammer, Qiming Machinery has had manufactured high-quality shredder hammer over 30 years. As shredder wear parts specialists, we have developed advanced alloys and manufacturing techniques that really pay off in demanding applications such as solid waste shredding. We stock an array of hammers and grates for common shredders, so you can normally get the parts you need in a matter of days.

Function

The most-frequently replaced wear part is the bell-shaped hammer. Hammers impart the enormous kinetic energy of a shredder’s spinning rotor onto the metal being shredded. Hammers weigh nearly one-half ton new and number about a dozen on the rotor. The rotor with hammers and other wear parts collectively weighs as much as 60 tons. A motor as large as 10,000 hp is needed to attain an operating speed of about 500 rpm. In general, hammers need to be replaced when they have worn down to less than half of their initial weight. If only one hammer needs to be replaced, operators typically replace the opposite hammer, too, to keep the rotor in balance. On average, hammers are replaced once a day. If your operation could benefit from less downtime and fewer change-outs due to hammer wear life, give Qiming Machinery a call. Discover for yourself why our customers report excellent satisfaction with our high-hardness shredder hammers.

 

Material Selection

Qiming Machinery has used different materials to suit different working conditions. We are focused on designing and building first-class equipment that gives our customers the highest availability and minimizes downtime.

Manganese Shredder Hammer

Manganese Shredder Hammer

We are the best manganese shredder hammer manufacturer in China. Our manganese shredder hammer span life can 20% more than other suppliers. The manganese materials are: Mn14Cr2, Mn18Cr2, Mn22Cr2

Manganese shredder hammer has a very high resistance to crack propagation. If operating conditions cause the yield strength in a region to be exceeded and a crack forms, the crack tends to grow very slowly. In contrast, cracks in low alloy steel castings tend to grow rapidly, which can lead to quick failure and the need for replacement.

Alloy Steel Shredder Hammer

Alloy Steel Shredder Hammer

Our engineer had used 30CrNiMo alloy steel to cast a shredder hammer. Under this material, the shredder hammer can get different hardness: The bar of shredder hammer’s hardness around: 35-40 HRC, The working area of shredder hammer’s hardness around 45-55 HRC. Because of different hardness, the shredder hammer can get more span life.

Qiming Machinery offers design and wears life analysis with three common alloys for improved wear life: Mn14Cr2, Mn18Cr2 with tungsten carbide insert.

Under this material, Qiming Machinery TIC inserts shredder hammer can get better metallurgy for longer wear life and significant cost savings. Its span life can be 2.5-3 times than normal manganese shredder hammer.
