Forsberg Destoner model P4R

Good used serviceable condition.  Does not come with a fan, but one can be matched up from our inventory for additional price.

The Forsberg Destoner Model P4R is a vacuum-type destoner designed for two-way separation of dry granular materials based on weight and density. Key features include a large 13 3/4-inch air column, external fan requirement, 1 horsepower motors for shaking and the metering roll, and adjustable controls for the air baffle, feed rate, pitch, elevation, and shake speed. It uses a high-speed eccentric deck motion and air drawn through a screen to separate lighter products from heavier impurities like stones.

Key Features and Functionality

• Vacuum Type: The P4R is a vacuum destoner, meaning it requires an external fan to pull air through the deck and product, creating the necessary airflow for separation.
• Two-Way Separation: The machine separates dry, granular products into two fractions: a lighter, cleaner product and a heavier fraction containing impurities such as stones, glass, or metal.
• Eccentric Drive: The destoner uses a high-speed, counterbalanced eccentric drive system that provides controlled, counterbalanced motion to the deck, ensuring stable and vibration-free operation

• Adjustable Controls: The P4R offers several adjustments for optimal performance, including:
• Air Baffle: Controls the amount of air flowing through the product for precise separation.
• Infeed Adjustment: Regulates the rate at which the product is fed into the machine.
• Pitch and Elevation: Allows for adjustments to the angle and height of the deck.
• Shake Speed: Controls the intensity of the deck’s vibration.
• Air Column: The air column measures 13 3/4 inches in diameter, creating the necessary air column for the separation process.
