Ross serves the requirements of the Chemical Process Industries, in virtually every industrialized country around the world. We have the experience and production capacity that no other manufacturer of specialty mixing and blending equipment can match. In the USA alone, we operate five plants, an analytical laboratory and a vigorous R&D program. Overseas, Ross equipment is being built in our own factories in China and India, and manufactured under license in other counties. Typical applications include mixing, blending, particle size reduction, emulsification, homogenization, powder induction, vacuum processing and more.
Specifications that define a mixer built for a chemical industry application reflect a combination of industry standards, and the mixing functions needed for that particular application. A sub-micron emulsion, for example, requires high-shear agitation, vacuum and usually a heat-transfer system. The size of the mixer is determined by the throughput required. To guard against batch-to-batch contamination, CIP and SIP capabilities are available, along with such devices as air-purged seals and custom designed discharge valves. To ensure a high degree of repeatability and to document the production of every batch, we often add a control system with data-logging capability.
The close connection between specific performance requirements and equipment features is the logical starting point for equipment design. But today, the challenge of specifying and designing a high-performance mixer is more than a two-dimensional process. We regularly address performance needs that are much broader than one particular mixing application. In fact, we often custom design equipment to meet production needs that have not yet been imagined.

The ROSS Model HSM-405SC-25 is an inline high shear rotor/stator mixing system incorporating SLIM (Solids/Liquid Injection Manifold) Technology. Unlike conventional eductors, the unique SLIM rotor/stator generates a powerful vacuum without the aid of external pumps and pulls powders directly into the mix chamber, promoting instantaneous wet out under high shear conditions. Mounted on a multipurpose skid with load cells, actuated valves and level switches, the pictured HSM-405SC-25 recirculates into a 400-gallon jacketed tank and is controlled from a 15” industrial PC with Windows.
Ross V-Blenders are most often used for the intimate dry blending of free flowing solids. The solids being blended in these units can vary in bulk density and in percentage of the total mixture. Materials being blended are constantly being split and intermixed as the shell rotates. Normal cycle times are typically in the range of 15 minutes, however can be less depending on the difficulty of blending.
Ross Double Cone Blenders design is most often used for the intimate dry blending of free flowing solids. The solids being blended in these units can vary in bulk density and in percentage of the total mixture. Materials being blended are constantly being intermixed as the Double Cone rotates.
Ross is the leading supplier of Ribbon, Tumble and Vertical Blenders for dry powder blending and drying for the process industries. Many products including pharmaceuticals, foods, chemicals, fertilizers, plastics, pigments, and cosmetics are manufactured in Ross dry blending equipment.
Ross is offering a new high-efficiency charging hopper for its line of High Shear Mixers with Solids/Liquid Injection Manifold (SLIM) Technology. The SLIM is a unique rotor/stator device engineered for high-speed powder injection into liquid without the need for eductors or pumps. The improved hopper design ensures a steady rate of feed delivery and prevents “rat holes” or bridging of bulk solids. Typical solids dispersed using the SLIM include fumed silica, CMC, guar gum, carbon black, carrageenan, xanthan gum, talc, alginates, pectin, titanium dioxide, calcium carbonate, starch, clays, alumina, carbomers, sugar, salts, dye powders and other additives or fillers.
The new line of Model 42C Cylindrical Ribbon Blenders are designed to mix dry powders, wet granulations and paste-like materials with densities up to 100 lb/cu.ft. Available in many sizes from 1/2 to 1,000 cu.ft. working capacity, Cylindrical Ribbon Blenders can be built for atmospheric, full vacuum or internal pressure operation. A full range of standard, heavy-duty and sanitary models are offered.
Ross SysCon is your single source supply for skid mounted Process Automation. Ross' diverse group engineers and designers has years of experience in multiple different industries ranging from Aerospace to Pharmaceuticals, Pulp and Paper to Automotive, Specialty Chemical to Natural Gas Storage.

Efficiency, consistency, and repeatability are qualities the chemical industry strives for in mixing operations. However, finding the right mixing equipment, and the right mixer manufacturer, can be challenging. This article offers considerations for choosing chemical mixing equipment.
ROSS VersaMix Multi-Shaft Mixers incorporate a proprietary powder induction feature for efficient charging of thickeners to produce high-quality gels, creams and pastes. The VersaMix includes a three-winged anchor and a high speed disperser blade which provide a robust combination of shear and bulk flow at various stages of the mixing cycle.
ROSS is pleased to announce the completion of a major expansion of its facility in Nantong, China. After more than 20 years of a successful joint venture, Nantong Ross Mixing Equipment Co. Ltd. has pushed ROSS to become the world's largest supplier of ribbon blenders in China.
ROSS builds advanced Discharge Systems with mechanisms to seamlessly fit almost any high-viscosity application.
The ROSS VCB-0.25 Tumble Blender is uniquely suited for specialty blends with extremely minor active components and additives. Ideal for processing high value and delicate applications, the Tumble Blender is often provided in a sanitary all-stainless steel construction and imparts gentle agitation.
The Ross VMC-1000 VersaMix is a 1,000-gallon Triple-Shaft Mixer available on a pivot-design single-post hydraulic lift.
Finding the right mixing equipment isn’t as simple as selecting an item from a menu. This article is a guide to considerations when choosing pharmaceutical mixing equipment and vendors for a facility.
Answering the need for high shear in formulations too viscous for conventional dual-shaft mixers, the ROSS PowerMix is a hybrid planetary mixer equipped with the patented High Viscosity “HV” Stirrer Blade providing axial product movement and radial exposure to a High Speed Disperse Blade, which in turn breaks down agglomerates and promotes rapid solids wet-out. Both the stirrer blade and saw-tooth disperser revolve around the batch while rotating on individual axes at independent speeds.
ROSS, a manufacturer of specialty mixing equipment, introduces a more versatile mixer/reactor especially suited for temperature-critical formulations of medium to high viscosity under stringent vacuum/pressure constraints.
ROSS introduces a special Triple-Shaft design specifically suited for hot melts and viscous dispersions. The latest ROSS Model CDA-800 has a mixing capacity of 500 – 800 gallons and is designed for full vacuum operation (29.5” Hg).
ROSS has unveiled improvements to the dual-post hydraulic lift and seal design of its 1,500-gallon Multi-Shaft Mixer (Model PVM-1500). The new lifting design is a double-acting, fully hydraulic cylinder operating at a much higher pressure, allowing for a smaller cylinder and significantly less oil for operation.
