Morris, Minnesota — A new machine for sand production and fines recovery from Superior Industries features a hydrocyclone made using polyurethane and other materials which last longer than older models.
Polyurethane gives superior hydrocyclone models

Polyurethane wear components give improved wear: Superior Industries
The hydrocyclones within the 12-inch and 16-inch (30 and 40cm) models of the firm's Spirit Sand Plant are manufactured with 100% cast urethane, between 10mm and 25mm thick.
Hydrocyclones are machines which can separate mixtures of particles into different sizes.
Superior Industries claims the material is lighter and easier to handle than steel, as well as having better wear properties. The larger 24-inch and 36-inch (60 and 90 cm) models are made from structural steel, but incorporate a poured urethane liner.
Each cyclone is designed with a geometrically efficient offset feed. The firm said that this design is claimed to eliminate inefficient turbulence ad reduce wear on the components.
