Shredder hammer

SINCO offers a complete line of custom-designed shredder hammer for all automobile and scrap metal shredders. We can match hammers and grates to meet your specs. We’ve worked with leading shredder operators for decades to improve the wear resistance of all shredder components, through improved design, metallurgy and quality assurance.

Made-to-order to fit most auto and scrap metal shredders, hammer mills, and horizontal metal grinders, Sinco shredder hammers reduce wear cost to help you achieve better tons out than competing castings.

The material of our shredder hammer is austenitic manganese steel and alloy steel containing chromium, nickel, and molybdenum. These 2 material different from the hardness to toughness based on different customer use.

Low alloy steel hammer

Low alloy steel hammers often deliver a lower cost per ton than manganese hammers. With the high hardness no less than 450BHN, the low alloy steel hammer have better performance in crushing. Of course it required the hammer not crack which is common to happened in our competitors products.

Thanks to our technical engineer. We get alloy hammer with both good toughness and high hardness though special heat treatment process. The result is a long-wearing, durable wear hammer that delivers more tons between grate changes and less casting-related downtime.
