Time is money, and the Con-Tech High Performance drum makes both for you all day, every day. Innovative fin design with enlarged washout holes in the fins makes clean up quick and easy. The patented Ball Busters® virtually eliminate cement balls and aggravated job site inspectors.

Sep 25, 2017 · More specifically, this invention relates to a helical mixing fin assembly for mixing and moving materials within concrete mixing drums that involves a superior fin structure and system for...

The new self cleaning fin design allows for small amounts of material to pass through the fins which drastically reduces build up. Elevated surge fins allow water to flush underneath to reach the main fin row during clean up. Straight Cone Taper allows for a smooth discharge with virtually no surging, while allowing maximum discharge ...

The mixing fin assembly includes a dual spiral mixing fin system designed to extend transversely into a drum mixing space. The fin assembly is preferably constructed of elongate shaped...

Fin configuration is engineered to maximize performance and advanced manufacturing technology ensures long service life. Drum fabrication employs precise cutting, rolling, joggling and submerged arc welding.

series of computational fluid dynamic (CFD) analyses in an effort to create a single fin mixer based on the effective fin technology used in the 4-fin 3050 mixer. The results of the evaluations showed that a single central fin, with supporting side fins provided excellent performance. Mixing performance was

Mixing fins provide agitation so that material rotating within the mixing drums may be intimately co-mingled. In this manner, the mixing process is enhanced to provide a...

Aug 21, 2010 · I wondering if mixing 2 different types of fins together would be worth trying in the quad setup... the larger M7 that came with the board, and instead of the M3, use the JW-1 fins in place of them in the back.

Feb 9, 2025 · For this you have two solutions: - with an US box, use a tool-less center fin (either FCSII or a finjak), so you can move around the rear without going in. Moving a bit the rear fin makes a lot of difference. - bring a spare fin.

Apr 29, 2015 · Different fins are defined by the amount of flex they have. In this section we break down the differences in stiff to flexible fin types and how they are impacted by wave size as well as their turning and overall rideability. Speed Generating Flex: Fins with more flex and engineered foils are the best for speed generating fins.
