Challenger™ Agitators
Challenger™ Agitators are hand crafted and precision machined to maintain a clean, efficient mixing action with minimal wear on seals and bearing components. Challenger™ agitators are constructed with solid shafting that extends the full length of the mixer. The spokes are fabricated from steel plate and then polished with a grained finish. The spokes are welded 360° around the shaft with large radius fillet welds for ease of clean-out. The agitator assembly is then machined in a lathe to remove any heat distortion in the seal and journal area of the shaft. Shaft run-out of every Challenger™ agitator is held to within .004” throughout the seal area. This extra step minimizes wear of seal components and prolongs bearing life.
Welded Paddle Agitators
Double Ribbon mixers are capable of performing a variety of mixing operations. These agitators are excellent for low density, free flowing materials. Ribbon mixers are designed for thorough end to end mixing. Two inner spirals move the product away from the discharge, while the two outer flightings move the material back toward the the discharge opening. The mixing action occurs by rolling the material back and forth. Marion's design provides a continuous spiral from the end of the mixer to the discharge. There are no gaps in the flighting to interrupt product flow and create "pockets" of stagnant material. Marion's ribbon design includes two sets of flighting on both the inner and outer spirals. Each spiral is positioned 180 degrees out of phase. The additional flighting provides twice the mixing action of a single ribbon mixer. In mixes with small agglomerates, the greater shearing action of a ribbon mixer can be beneficial.
Pasta Agitator
Double Reversing agitators are a hybrid between a paddle and a ribbon. With paddles located at the inner and outer radii, the agitator provides the "figure 8" movement of a paddle style mixer with the scrubbing action of a ribbon blender. This aggressive mixing action transfers more energy to the product being mixed than either the standard paddle or ribbon agitator designs. This agitator design creates a more even product level in the mixer, thus allowing larger capacities to be mixed per batch
Double Reversing Paddle/Paddle
Monroe Engineering manufactures railroad bulk sand handling systems. Sand storage towers are engineered and manufactured to meet customer specifications, safety and facility layout requirements. Storage tanks range in size from 10 to 35 tons. Monroe sand handling replacement parts include weatherproof nozzles, sand hose, clamps, adapters, bin level indicators, shut-off valves and dust arresters.
Another hybrid variation similar to the double reversing (paddle/ribbon) agitator is the double reversing (paddle/paddle) agitator with (2) sets of paddles moving in opposite directions in a figure "8" movement.
