Power Grater

Power Grater


The Power Grater consists of a dust tight casing containing a paddle assembly that gently rubs the product to be reduced against a formed grating screen for clean, efficient reduction. Low paddle speeds of approximately 88 RPM for single speed models result in less fines.
