Precision sizers
Improve consistency with accurate width and thickness sizing
Size Right® precision sizer
Models: SR 1, SR 2, SR 4, SR 6
The Size Right® precision sizer is designed to accurately separate materials based on their width and thickness, ensuring optimal uniformity in seed, grain, and industrial processing applications. By using rotating cylinders with precisely engineered indentations, this machine effectively sorts products into specified size categories, improving quality control and downstream processing efficiency.
Whether used for agricultural commodities like wheat, corn, and soybeans or industrial materials such as plastic pellets, the Size Right® 2 enhances consistency by removing oversized or undersized particles. This level of precision is critical for seed conditioning, where uniform sizing impacts planting efficiency and crop yield. Additionally, the machine’s adjustable settings allow for customization based on material characteristics, maximizing throughput while minimizing loss. Built for durability and ease of operation, the Size Right® 2 helps processors maintain high-quality standards, reduce waste, and improve overall productivity, making it an essential component in any advanced sorting and grading system.
Key features:
Processing up to 25,800 pounds per hour
Variable frequency drive for cylinder speed
Real-time digital speed control and RPM readout
Stainless steel drive shafts for longer wear life
Felt inlet rings prevent leakage when product is entering the cylinder
All adjustments safely made while in operation
How do Oliver Manufacturing precision sizers work?
Oliver Size Right precision sizers separate materials by width and thickness to deliver accurate, consistent sizing and cleaner products.
Material enters the sizer and spreads across multiple sizing decks. Each deck contains rows of oblong openings. Particles that are small enough to pass through the openings fall to the next deck. Particles that are too wide or too thick are carried forward and discharged at the end of that deck. This process continues until each particle is sorted by its width and thickness.
A combination of gentle vibration and controlled airflow keeps material evenly distributed across the deck surface, preventing balling or tunneling so every particle has a fair opportunity to be sized.
Deck angle, stroke, and air volume are easily adjusted to match different products and sizing requirements, giving you precise control, repeatable results, and high-quality fractions.
Particles are separated by width and thickness. Smaller particles pass through the openings to lower decks. Particles that are too wide or too thick are carried forward and discharged at the end of the deck where they are removed.
