Equipment Recommendation Tool

Not sure which machine would best serve your size reduction needs?

Select your unit of measurement and desired finish size and we’ll determine which machine to use.

Improves product flow for a variety of applications while reducing product agglomeration for an all-around easy means of reducing compacted materials.

Easy installation and maintenance, make this a simplistic product for businesses of all sizes and types. At Prater, we construct only the most versatile equipment and our lump breakers are no exception. It can process an extensive array of materials, including chemicals, minerals, salt, sugar, ceramic powders and more.

Flake Breaker

Our exclusive G-Series, Full Screen, Hammer Mill is specifically designed for applications that require high capacities, power efficiency and uniform particle size. This provides our customers with confidence in knowing that we have the ideal machine for their unique particle reduction applications.
Our exclusive Full Screen design is a proven system that ensures use of the entire available screen area which enhances end product quality and hammer mill productivity. Our proprietary design factors combine to provide a controlled, uniform granular grind with the benefits of easy maintenance.

G Series Mill

Bridging the tough gap between hammer mills and fine grinders. Our Mega Mill provides uniform grinding with less heat build-up. A unique cantilevered arrangement creates a smoother, quieter operation, 24 hours a day and 7 days a week. The Mega Mills run more efficiently and with less airflow than conventional hammer mills. Reduced downtime, maintenance and power requirements result in a cost-effective product that will benefit, not hinder your material processing.

Perfect for applications including animal feed, cereal, fertilizer, sugar, spices (salt, chili pepper, nutmeg, paprika, and more), wood shavings, wood chips, wood waste, whole soybeans, diatomaceous earth, and various grains (rice, oak, wheat and more). The Mega Mill Hammer Mill is ideal for any size operation.

Mega Mill

Allows customers more capacity, better dust control, simple maintenance, standard safety features and precise control of the finished particle size and distribution. The large screen area to horsepower ratio allows for more capacity than other fine grinders on the market. Our fine grinders’ outboard bearing design and dual o-ring seals on the large access door ensures a more dust-controlled grinding environment. Additionally, quick and easy removal of the reversible rotor is possible with the removal of one bolt, allowing rotor blades to be efficiently replaced without any further balancing of the rotor.

Fine Grinder

The CLM Air Classifying Mill offers the combination of two-stage closed circuit grinding mill with internal air classification, all in one efficient unit. The unique capabilities of the CLM Air Classifying Mill outperforms single-stage air classifier mills when handling difficult to grind products and those products requiring a narrow particle distribution.

Classifier Mill

The MAC Air Classifier forced vortex unit processes dry materials to an unmatched fineness and uniformity over a wide range of feed variations, either in closed-circuits with a conventional milling system or as independent “stand-alone” systems that incorporate a feeder, fan and product collection equipment. This MAC air classifier works best on crystalline products that are dry and have a narrow distribution, preferably minus 50 micron or better. The MAC can be installed within existing air systems with very little modification necessary. Available in many sizes and in either mild or stainless steel, the MAC units can also include convenient optional equipment such as ceramic rotors and abrasion-resistant steel, rubber, polyurethane or ceramic linings.
