Read about the Up-Flow® technology....
The Roto-Finish Up-Flow® is the premier design in centrifugal disc finishing. Utilizing centrifugal force, the Roto-Max® machines produce fine finishes with a minimum of operator input and at rates of 3-10 times faster than vibratory finishing equipment. At the heart of this design is the upward flow of fluid through the precision-machined seal gap. This is the zone where the spinning rotor makes the transition to the stationary sidewall or wear ring that results in the toroid action. This critical zone is factory machined to a gap of .012" and .003" maximum run out. Creating this precision is done for a reason. A precision seal gap allows for symmetrical fluid flow and hydrostatic balancing of the rotor, necessary for an Up-Flow ® design.
The Roto-Finish Up-Flow® - the premier design in centrifugal disc finishing
In the Roto-Max® design, the process fluid or solution enters the machine through the seal gap at a rate of at least 10 gallons per hour per cubic foot of capacity and while processing, carries these contaminants out of the side bowl drains and, at the end of cycle, through the patented center drain. With older, inferior designs, the solution flows in over the top of the mass and forces the drainage of contaminants through the seal gap. This causes excessive wear of the gap area. An adjustable seal is not an advancement but a patch over a very old design flaw. The seal gap in the Up-Flow® can’t wear. It sees nothing but water and compound.
The down-flow is old technology and has a number of process drawbacks. The mass tends to run drier and thus provides less cushion and promotes higher media wear. The net result is an excessive amount of media sludge, fines, chips and abraded part material flowing through the critical seal gap. The pressures generated in this flow by gravity and the spinning rotation causes erosion of the seal and the lower drive housing for the rotor and the bottom cavity wall. In addition, using the seal gap as the drain retains fluid in the bottom of the rotor. This makes for "sloppy" processing when the machine is emptied and creates a sludgy start up condition when the next process is started. Some down-flow designs drain through the bottom of the rotor to reduce this sludge retention, however the sludge still drains into the cavity below the rotor and creates wear problems for the drive seals and drive shaft.
