The horizontal cylindrical dryer design includes either a ribbon or paddle agitator, depending on the materials and the range of volumes to be dried. The agitator continuously moves the materials within the vessel, past the jacketed trough walls until the desired moisture content is achieved. Cylindrical dryers are available from .33 to 343 cu.ft. working capacity, and can be supplied with a wide range of features to suit each clients special needs.

V-Blenders designs 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. V-Blenders are stocked in 5, 10, and 15 cu.ft. capacity. Each is constructed of type 316-stainless steel and is internally polished to a 240 grit sanitary finish. The exterior is polished to an easily cleaned 150-grit finish. All Ross V-Blenders are supplied with Intensifier bars to permit deagglomeration as needed. Discharge is accomplished through a manually operated Butterfly valve. The valve is positioned 24” from the floor when in the bottom position. All units are provided with appropriate safety railings and appropriately interlocked safety interlocks. Stop-Start and E-Stop Pushbuttons are included with all blenders.

The High Viscosity Disperser is a useful mixer when slow speed-high viscosity paste mixing is required. The PBA Model includes an airoil hydraulic lift to raise and lower the agitator from a mix can. The agitator is either a slow speed Turbine or a Bow Tie design. As the agitator rotates in the batch of material, it gently blends the product until full homogeneity occurs. Wetted parts are normally of stainless steel construction and drives are designed for variable speed operation using a Variable Frequency Inverter.

Our Kneader Extruder combines the efficiency of a double arm - sigma blade mixer with the convenience of an extrusion screw for the mixing and discharging of heavy viscous materials. The Kneader Extruder includes a set of counter-rotating kneading blades and a discharge screw. The blades are mounted on a horizontal axis in a u-shaped trough. Below the blades in a separate cavity is the discharge screw. During the mixing cycle the blades rotate toward each other while the mixing screw rotates in a reverse direction, constantly feeding new materials into the mixing blades. After the mixingkneading cycle is complete, the screw is reversed and it transports the mixed materials from the mix zone out through a discharge die and on to further processing or packaging. The Kneader Extruder has several advantages over conventional non-screw discharge kneaders: 1. Mixes in approx. 15% less time 2. Eliminates the manual task of scraping out stickytacky materials. 3.Eliminates operator exposure to materials of elevated temperatures or of a toxic nature, thereby improving plant safety. Many sizes and designs are available to meet the most stringent process needs. Kneader Extruders are manufactured in many sizes from 1 through 1000 gallons capacity.

We offer Dual and Triple Shaft designs to meet the specific requirements of each customer. The economical Dual Shaft design includes a two-wing anchor agitator and a conventional high speed disperser. This combination is ideal for straight forward mixing and dispersion applications. The triple shaft design extends the operating range by adding either a high shear rotor-stator mixer or a second high speed disperser. The addition of a high shear rotor-stator mixer adds the capability of emulsifying and homogenizing products that require higher shear to reduce the size of the particles being mixed.

This stainless steel vessel is ideal for a variety of deaeration requirements. The vessel isconstructed of type 304 stainless steel, has a 600 gallon capacity with interior surfaces polished to a 120 grit finish.
