Seed and grain length separators
Precision sizing for more uniform seed and grain
High-accuracy grading equipment for seed, grain, and specialty processing
When product size and uniformity matter, precision grading helps processors create more consistent fractions and improve downstream performance. Oliver Manufacturing offers Westrup grading equipment designed for accurate size separation across seed, grain, food, and specialty processing applications.
Using carefully engineered screens and controlled product flow, Westrup graders separate material into highly consistent size fractions, helping remove undersized or oversized product, improve uniformity, and increase the value of finished material.
Accurate grading starts with controlled product flow
Effective grading depends on maintaining an even flow of material across precisely manufactured screens. Westrup graders are designed with low screen inclination and tight perforation tolerances to provide highly accurate sizing and dependable separation.
This level of control makes grading especially valuable when processing high-value seed or applications where consistent product dimensions are critical to quality, planting performance, packaging, or further processing.
Separate product into consistent size fractions
Westrup graders can classify product into multiple fractions in a single process, helping processors create more uniform lots while removing material that falls outside the desired size range.
Depending on the application and equipment configuration, grading can help improve product consistency, remove undersized or damaged material, and prepare seed or grain for additional cleaning, gravity separation, treatment, or packaging.
Grading solutions for a range of processing needs
Oliver offers Westrup graders for applications ranging from lower-capacity processing to larger commercial operations. Available systems include equipment designed for precise four-fraction sizing as well as flat-screen sizing for lower-capacity applications.
Our team can help evaluate your material, required capacity, desired fractions, and processing goals to determine the grading configuration best suited to your operation.
