In wood industry operations. the disposal of bark can pose difficult and costly problems. Until now, bark has been hard to reduce, especially when wet and stringy. Accumulated in scrap piles, its leached acids can pollute nearby streams and water supplies. Burned, it contaminates the atmosphere, a much-criticized practice that is now outlawed in many communities. Hauled away to the town dump or for landfill, it has no economic value and, of course, involves trucking costs.

But bark, when properly processed, has the potential for serving many useful purposes and of bringing to its supplier substantial dollar gains.

NOW THERE IS A WAY.. AND A MARKET

The Schutte Bark Grinder, a unique machine designed specifically for this service, pulverizes the bark into fine or coarse particles processed and marketed directly as, or sold to producers of: Ground cover, mulch, soil conditioner, animal bedding, potting soil and similar mixtures, compressed fireplace logs, industrial fuel, flower pots for nurseries, organic based fertilizers, particle board, hardboard, insulation board, roughage supplement in livestock feed, filter media, to name a few of innumerable end uses.

REDUCES ALL BARK TO MARKETABLE FORM INSTANTLY

This Schutte unit will take any bark material you choose to feed into it: Wet, stringy, troublesome types that could never be ground successfully before.

And it all comes out in a density and size that command top price on the resale market.

EXCLUSIVE RIBBED GRINDING PLATES PROMOTE FIBER DISINTEGRATION

An upper ribbed liner plate and a lower ribbed baffle plate provide the primary grinding action. These special, Schutte-designed plates break up the bark to such an extent that no screen is necessary for the production of ground covers, mulch, soil conditioners, animal bedding and other coarse products of saleable quality.

When a finer grind is needed for specific markets, a removable Schutte screen is inserted in the Bark Grinder to turn out particles of stated specifications.

UTMOST OPERATING AND SERVICE SIMPLICITY

The Schutte Bark Grinder features a top feed, which directs the material to the hammers for instant grinding action. A minimum of wearing parts contributes to maintenance economy and long service life.

A quick-opening cover provides easy access to rotor, hammers, and liner plates should turning or replacing be needed. Only a few bolts need be removed to unfasten the cover allowing it to hinge down.

GRAVITY DISCHARGE OR SELF-POWERED FAN SYSTEM

Depending upon the species of bark being ground, Schutte Bark Grinders are designed for ether gravity discharge or with Schutte's own motor-driven fan system.

The six-blade vacuum fan in Schutte's system provides maximum capacity with minimum power consumption. For extreme wear applications, hard-faced impeller blades can be furnished. An adjustable air inlet plate helps maintain constant suction and a clean grinder. The housing is equipped with a replaceable liner and is designed to allow renewal of both fan and liner without disturbing the blow pipe.

TOUGH, HEAVY DUTY CONSTRUCTION

Years of trouble-free performance are assured by all-welded, extra-heavy (3/4") boiler plate construction. The rugged rotor features thicker-than-normal discs. A heavy, heat-treated alloy steel drive shaft, supported by oversize self-aligning ball bearings enclosed in dustproof housings, resists the shock of overloads.

SIMPLE, SPACE-SAVING DESIGN

Self-contained, the Schutte Bark Grinder requires minimum floor space. Only one, extra heavy shaft is used. Troublesome, awkward auxiliary shafts, belts, and pulleys are eliminated. The inlet hopper is attached to the machine in a fixed position for a permanent feeding setup, allowing the grinder to be placed close to a wall or in tight corners.

LONG-LASTING SCHUTTE HAMMERS

Heavy notched hammers are made from fine, close grain, specially hardened steel. They retain their sharpness and have the toughness to withstand wear. For applications involving extreme wear, heavy, hard-faced strap hammers which retain their sharpness longer, are available also.

CHOICE OF DIRECT OR BELT DRIVES

The motor mounting, an integral part of the grinder, can be arranged for either direct or V-belt drives. (V-belt drive is recommended for use with slower speed motors or power units.)
