A well-matched scrap metal recycling plant program is ready to expand as market demands change. Choosing the right metal shredder ensures performance and capacity are in place to meet the demands of future operational growth.
The Industrial Service Solutions – Recycling Technologies 7090 stationary automobile shredder is ready to meet increasing scrap volume and scrap weight demands. The 7090 shredder features a proven spyder or disc-style 70-inch rotor, filling the gap between traditional 6090 and 80104 units. The 7090 rotor delivers 32% greater impact than the smaller 60-inch designs, while being built with the same material specifications as found on larger 80-inch mills.
The 7090 shredder averages 40 tons per hour with a 1,000 HP motor setup, and up to 100 tons per hour at 4,000 HP. A Hagglunds feed roll drive delivers longevity and ease of maintenance, while a feed roll cover ensures a safe, clean operating environment by preventing material from flipping onto the shredder housing.
1. Type of Material to be Processed
Different types of shredders excel at processing specific materials. Tree branches are typically shredded using a high-speed chipper. Plastics are most often processed in a granulator (rotary knife cutter) however; bulky plastic shapes are often put into a shredder as a first stage before granulating. When planning to shred cars, this type of application is typically accomplished using a hammermill. Although, processing a variety of waste materials may require versatility with a minimal amount of noise and dust, then a twin shaft shredder can be the optimal solution.
2. Desired Output
Understanding the output size requirement will help in determining the type of equipment to install. Some facilities require the material to be separated, whereas others may need re-shredding and grinding. A single-pass shredder will cost less but if the material needs to be reduced to a very small size and compressed then compaction equipment may be required.
3. Capacity

Choosing an industrial shredder to handle the correct capacity is important to the success of any installation. Capacity is typically expressed in pounds per hour and is determined by the physical size, weight (bulk density), and the amount of material to be shredded. The capacity may be limited by the cutting chamber size. Check the capacity rating carefully before purchasing the machine and allow for some excess capacity. Using a shredder with a maximum capacity too close to the desired capacity can lead to a shortened service life. However, over-sizing a shredder by a wide margin can lead to excessive power use and take up too much floor space.
4. Feed Type
Two basic feed types are common: manual and automatic. Manually fed shredders usually have a hopper and work by either hand feeding the material or using a fork lift to drop the material in. Automatic feeders or conveyors help optimize shredder performance by giving a constant and regular supply of materials to the shredder.
5. Operational Considerations
Portability, safety, and noise are concerns when selecting a shredder. Select the proper location for the shredder because it is not easy to move a machine weighing a half ton or more. Depending on the material, dust and other airborne particles can be an environmental hazard. Noise is another factor to consider as some shredders (such as hammermills) create more noise than others.
6. Maintenance
Shredders endure a great deal of stress and maintenance is necessary to keep them running efficiently. Cutters, blades, or hammers will wear under normal use and require sharpening, adjusting, or eventually replacing. Consider maintenance, repairs, and ease of obtaining replacement parts when choosing a manufacturer. Always evaluate the access location for maintenance when determining where to locate any equipment including your shredder.
