Premier Mill's VHD single shaft mixer offers efficient mixing of low to medium viscosity, free flowing liquids or dispersions requiring a high level of hydraulic shear produced by a high speed disperser blade, while the ESD Prem-a-mix dual shaft mixer combines high shear dispersers with fluid flow support, enabling the user to process higher solids or viscous formulations completely in change-can processes. Faster batch times, greater flexibility and consistently repeatable dispersions are the benefits offered by the company's single-shaft, dual-shaft and multi-shaft Prem-a-mix dispersers. In addition, the Premier double planetary mixer offers an efficient way of mixing and handling difficult, sticky, tacky, high viscosity pastes and gelatinous mixes. Maximum mixing efficiency ranges from a few thousand cps to several million cps. Vacuum mix is not only more uniform, but 30% faster than other double planetary mixers, according to the company.

Kady International reports that it can help maximize existing equipment in a current production line without the cost of a major equipment overhaul. The Kady Continuous Flow Mill utilizes the kinetic dispersion concept, assuring enhanced tank flow and batch uniformity, according to the company. In addition, the company has made available the Kady 100T, a versatile top entry dispersion mill for large production requirements. With rotor tip speeds of 9,000 feet per minute, fine dispersions can be achieved quickly. This power can reduce the need for pre-wetting and increase production, according to the company.

With the introduction of the HSD Immersion Mill into its multi-shaft mixer, Hockmeyer has created the Multi Tasking System (MTS). This single machine typically consists of a high speed dispersion drive, Hockmeyer's patented HSD Immersion Mill and a low-speed drive with helical blade. Even the de-aeration process is all done in this single machine, according to the company. The MTS unit has been tested at Hockmeyer on-site laboratory, processing a 250 pound batch of phthalo blue paste ink in a third of the time over the industry's standard processing system, representing a 200% savings in production time, according to a company spokesperson. Hockmeyer can customize the MTS to meet specifications with a variety of mixing tools to suit each user's needs. To further enhance the unit, the company has partnered with Vac-U-Max to offer dry powder feeding systems, as well as Gamajet, to offer high pressure clean in place systems.

New from Reynolds Industries is A.C.T., an automated, recipe-based system in which the entire mixing process is pre-programmed, eliminating inconsistent batches and increasing productivity. A.C.T. provides reporting on amp draw, blade speeds, temperature and much more, according to Reynolds. The company has also added a new dual-shaft helical blade mixer which is ideal for mixing medium to high viscosity products. A high-speed disperser is combined with Reynolds' patented helical blade low speed agitator to provide superior product turnover, according to the company. This mixer is available in a variety of sizes and mounts, and all systems are available in electric and hydraulic drives. Also available from Fort Mill, SC-based Reynolds is a full line of portable mixers in variety of drives and sizes. More info: Reynolds Industries Inc., 803-548-4301; Fax: 803-548-1365; E-mail:; Web:
