We know that
no two shredding operations
are alike.

That’s why our product engineers work with customers to achieve their unique production goals. If you need increased throughput, we can provide the components to do the job. Looking for greater density? We can match hammers and grates to meet your specs. We’ve worked with leading shredder operators for decades to improve the wear life of all shredder components, through improved design, metallurgy and quality assurance.
