Blender Imparts Low to High Shear Required for Blending Materials at High Rates

munsonCC 0453 3 6 14 056

Munson Machinery's new HIM-306-SS High-Intensity Continuous Blender imparts low to high shear required for blending, homogenizing, de-dusting and/or de-agglomerating of dry ingredients, slurries, pastes and difficult-to-blend materials at high rates. Fitted with coated, hardened stainless steel paddles for abrasion resistance, the agitator is supported by pillow block bearings mounted externally at opposite ends of the 30-by-72-inch (76-by-183-centimeter) diameter cylindrical mixing chamber, and is equipped with stuffing box-style air purge seals.

Homogeneous blends can be achieved in as little as 20 seconds residence time depending on material characteristics, yielding up to 1500 cubic feet (42 cubic meters) of throughput per hour, with other models in the series offering higher or lower capacities. The insulated, high-pressure jacketed mixing vessel constructed to ASME code can be heated or cooled, and is equipped with four injection ports for adding liquids in small to large amounts.

For washdown, water or cleaning solution is introduced through the ports before running the machine to dislodge any solids adhering to interior surfaces. For difficult-to-clean materials, an available gate at the outlet of the discharge chute allows the unit to be partially filled with water or cleaning solution prior to running the machine. In either case, the vessel can be drained through a flanged outlet on side of discharge chute.

The agitator is driven by a 50 horsepower (37 kilowatt) motor with totally enclosed high-torque gear reducer and synchronous belt drive, and rotates at variable speeds ranging from 120 to 600 RPM. The agitator is comprised of a large-diameter, solid shaft with 180-degree adjustable paddles for varying degrees of blending intensity. All material contact surfaces are constructed of #316 stainless steel for blending of corrosive materials. Contact surfaces and/or the entire support structure are also offered in #304 stainless steel, carbon steel and exotic materials.
