Particle Classifying Services


For precise particle classification of fine powders, our specially engineered ROTO-SIZER produces “cut” sizes down to 3 microns with yields of up to 92%. Our classifier is capable of removing oversize particles from your material. Classification can also remove objectionable fine particles, which can cause downstream process difficulties. Classifying your product can result in substantially increased value at minimal processing cost.

The ROTO-SIZER is engineered to provide the most efficient classification of your feed stock. It gives you ultimate control of particle size distribution and is adjustable within a wide range of speeds to produce the desired cut point. Efficient rotor and chamber designs ensure that the highest quality product is manufactured.

The ROTO-SIZER System is constructed entirely in the USA and we use only the highest quality components. Local manufacturing guarantees rapid delivery of spare items. Comprehensive engineering and durable construction enable our systems to operate continuously 24 hours a day, 365 days a year.
