JWC Environmental Introduces 1-SHRED/4-SHRED-1 Industrial Grinders

JWC Environmental introduces two new industrial grinders to its Monster Industrial SHRED Series. The compact 1-SHRED-H is suited for small facility use in recycling and small food processing and food waste applications, including food waste preconditioning for composting or anaerobic digestion. The 1-SHRED meets requirements of the International Convention for the Prevention of Pollution from Ships (MARPOL), making it appropriate for use in food waste disposal operations aboard ships or off-shore drilling platforms, according to the company.

The entry-level, dual-shafted grinder operates at low-speed and high-torque to deliver very high cutting forces. The 1-SHRED is tailored for use in wet or dry applications and does not require additional process water to grind products down to size. A small footprint and the ability to be mounted in a variety of orientations allows the unit to fit into tight space restrictions. The 1-SHRED incorporates bearings at both ends of the shafts to prevent shaft deflection and wear when processing tough solids and includes scrapers, which increase solids throughput for maximum grinding efficiency. The unit is PLC controlled incorporating a motor current monitoring auto-reversal sequence ensuring unexpected debris will not jam and damage the grinder.

The newly designed 4-SHRED-1-H model is designed for use in wet or dry applications. The grinder breaks tough, large waste down to size to reduce waste volume, optimize output for further processing and allow the waste to be recycled. The 4-SHRED-1 is a low-speed, high-torque dual-shafted grinder that offers an alternative to hammer mills in many applications. Customers can choose from three standard cutter combinations —7-, 11- or 23-tooth — to match the specific waste being processed and meet the final particle size requirements for the shredded materials.

The grinder incorporates standard individual steel scrapers between each spacer to increase solids throughput. The PLC controlled motor current monitoring auto-reversal reportedly ensures unexpected debris will not jam and damage the grinder. Drive motor options are available from 15 to 40 hp coupled with a variety of gear reductions.  Custom feed hoppers and stands are available.
