What are the advantages of a high speed grinder over a low speed shredder?

Keep up with the continually evolving ways of waste and recycling, land clearing, and mulch production jobs. Vermeer’s horizontal grinders are built to process organic materials in ways that deliver greater productivity than a low speed shedder. Read on to find out why a Vermeer horizontal grinder could be the best machine for your business.

1. Productivity

Most high speed grinders have a hammermill that spins anywhere between 1,100 to 1,200 RPM. These machines are typically assisted with some sort of feeding system. On the other hand, low speed shredders spin at 30 to 40 RPM and are often built without an assisted feeding mechanism. This core design difference results in a drastic difference in throughput.

2. Contamination Tolerance

You already know that slow speed shredders are designed to process contamination like chunks of steel and concrete, thanks to the rotor design and relief systems. But even if slow speed shredders are known for processing contamination, Vermeer high speed grinders are equipped with solutions to protect against contamination.

The first way to reduce the likelihood of contaminates in a high speed grinder relies on the operator. Using an excavator to grab material from the top of the pile, the operator can fluff the waste before putting it through the grinder. This allows contamination to fall out and simply allows the operator to see it before putting it in the grinder. By adding in an extra step in the operator’s process, you can increase your overall business productivity.

Additionally, Vermeer’s Damage Defense Technology is designed specifically to reduce the likelihood of contaminates spilling into the grinder. High performing sensors will detect materials such as metal and shutdown the machine before damage can be done.

3. Product Quality

Many slow speed shredders produce chunky inconsistent product and offer few options to control product size. This is a huge challenge for operations wanting to make a very specific end product. In these cases, a high speed grinder offers greater flexibility depending on cutter tip and screen size.

4. Estimated Cost of Operation

Fact is a slow speed shredder burns less fuel and its rotor tips last longer compared to a high speed grinder. But when looking at the cost per cubic yard or cost per ton, a high speed grinder offers an impressive productivity advantage making it much more competitive with a slow speed shredder.

At the end of the day, it comes down to you and your business needs.

Slow speed shredders are good for handing contamination such as construction and demolition debris and other forms of non-organic waste. The low speed, high torque design can handle contaminates strikes making it best suited for these applications.

Even if you have risk of contaminates, Vermeer’s high speed grinders have the advanced technology and workarounds to mitigate potential equipment damage. High speed grinders offer immense upgrades to productivity and are ideal for green waste and recycling, land clearing, and mulch production jobs. Its high speed mill, cutter tips, screen options, and feeding system make it ideal for these applications.
