The IFP (fixed) and IRP (rotating) line of pulverizers provides a solid grip to easily handle materials, says the company. Jaw shape is designed to reduce the variation in force between the start and end of the crushing cycle. A speed valve allows the jaw to close quickly under no-load conditions to shorten cycle times. Available in three model sizes, the attachments fit excavators from 19 to 55 tons. With operating weights from 3,800 to 7,100 pounds, the pulverizers provide a maximum force to 655,000 pounds at the cutters. The distance between the cutters can be adjusted to cut rebar.
