WSM’s Biomass Super Shredder allows processing of a wide range of incoming green feedstock (pulp chips, micro-chips, in-woods chips, sawdust, shavings, and hogged wood) for improved drying and sizing for pellet manufacturing.

The WSM Biomass Super Shredder is specifically designed to deliver high capacity and high speed milling of green fiber at rates from 10 to 75 tph. Available in rotor diameters of 42”, 48”, and 60” and rotor lengths from 36” to 88” long, these massive machines typically operate with 150–1000 HP. Features include modular and adjustable tooling with either rigid or swing hammers with replaceable inserts; large screen area with modular sizing screens to allow adjustment to product sizing; and heavy duty housing with interior wear liners and pivoting case access for long life and ease of maintenance. When combined with a WSM pre-screen, processing rates can reach up to 100+ tph.

Martin Engineering offers an innovative solution that prevents carryback released by secondary conveyor belt cleaners from sticking to the rear slope of the discharge chute.

If left to build up, material can encapsulate secondary cleaners and deposit harmful carryback onto the return side of the belt, fouling idlers and pulleys. The Martin Vibrating Dribble Chute uses material disruption to cause tacky sludge and fines to fall from the chute wall and back into the main discharge flow. By addressing these issues, operators can experience a reduction in maintenance hours, equipment replacement and downtime, lowering the overall cost of operation.

Prompted by customer requests, Martin engineers observed that the majority of the buildup released by secondary cleaners collected at the rear of the chute mouth, where a sloped surface can trap carryback.

Comprised of three parts, a low-friction polyurethane dribble sheet, a steel mounting bracket and a powerful vibrator, the combination of mechanical disruption and the slick surface prevents material from adhering and feeds it back into the main discharge flow. When the unit is mounted into the existing chute-work, it often extends the rear configuration closer to the belt, increasing the amount of material captured and further reducing spillage.

Rotochopper and KeyKnife launched the KeyKnife chipper knife package, which allows horizontal grinder owners to chip and grind with a single machine.

The chipper knife package is a bolt-in option that works with the standard patented replaceable mount rotor for the Rotochopper B-66 and B-66 E. This chipper knife system makes it simple to diversify into chipping applications without a complex conversion kit or a second machine.

To switch from grinding to chipping, the operator does not need to swap the whole rotor drum or assemble a complex overlay onto the grinding rotor – the operator simply swaps the grinder tooth mounts with chipper knife mounts.

A single operator can switch from grinder teeth to chipper knives quickly and easily:

This system utilizes patented Key Knife technology to minimize knife replacement costs. Key Knife chipping inserts are indexable (reversible). By simply loosening the knife clamp bolts, the operator can flip the knife to utilize a second chipping edge. A Key Knife insert uses significantly less steel than a traditional chipper knife, making handling and replacement easier. The chipper blade on each mount is much narrower than traditional chipper knives, helping to minimize the maintenance costs that can result from rocks, metal, and other contaminants.
