Compactors
These compactors were engineered to densify materials by applying pressure or by combining pressure with heat, binding agents, or moisture. Available in heavy- and severe-duty versions, the easily maintained units are versatile and energy-efficient systems for compacting, densifying, or briquetting material to the size, shape, and density required. They also ensure the solubility and friability needed in the process. These processing capabilities are used to improve flowability, solubility, dust control, and waste by-product recovery. In addition, the units not only reduce storage requirements, but also lower transportation and product-handling costs. The process utilizes counterrotating rolls to densify materials with the application of pressure. Material is transported into the nip area between the rolls by a single or intermeshing multiple screw feeder. Compression is achieved as the volume of material entering the nip area is squeezed through the rolls.

Mixer, Blender, and Agglomerator
The Extrud-O-Mix is often used to mix and blend dry powders and liquids into a paste or dough-like consistency. The unit then extrudes the mixture into free-flowing, dust-free pellets or particles. Dispersibility of the finished particles is excellent because, unlike high-pressure designs, the unit uses only the minimum force necessary to maintain particle integrity. The design is energy efficient, easy to clean, and simple to maintain. Features include adjustable shear input and heat transfer capabilities in the rotor and housing. Typical applications include detergent formulations, adhesives, sugars, and sugar blends.
