With its efficient design, our Roll Press Separator is mainly used as a complimentary machine to our line of Sidehill and Micro-Screen separators to maximize solids removal and the dewatering process.

Our Roll Press is manufactured with heavy duty stainless steel construction for longevity and strength, to prevent corrosion and easy cleanup for extended life in most applications. The press rolls are designed with rubber drive rollers and perforated screening rolls with internal augers. The press tension is set by the tension springs which are set at the optimal tension for a dryer but un-damaged  pressing and to prevent large objects such as rocks, rags, clothing, plastics and other troublesome trash from causing slippage or damage to the machine.

Key Dollar Separators has many sizes and configurations available that can be tailored to your needs. Our Roll Presses are available in 12”, 36” and 72” models to match our Sidehill and Micro-Screen models seamlessly. These are also available with fully automated controls to further fine tune to your separation and dewatering needs.

Our machines are also built using high efficiency drive components lowering the cost to operate - further saving you money.

“I would recommend Key Dollar to anyone because quality is their most important factor.”

Neil Michaels, National Frozen Food, Albany, Oregon

“Our Separator works very good and has saved us thousands of dollars of disposal cost. I highly recommend Key Dollar.”

“They have a regular pork farm system and use wood chips in the trucks while hauling the pigs. The truck wash system separates out the wood chips with a Key Dollar side hill separator. The water from this goes to a Key Dollar micro-screen separator with a 325 mesh screen. The water then goes to settling tanks and then to the fields for watering. The wood pulp floats off and the solids go to the soil.”– Testimony for the 325 Mesh Stainless Steel Screen

“We want to thank you for this machine. It is a “Deusie”. What is important is the fact that this machine has been basically trouble free since we received it. It has been used 360 days per year for years and we have run in excess of forty million gallons of septage through it with very few problems.”

 Les Elderidge, Tenelco, Inc., Lake Stevens, Washington

“My wastewater is pumped with a 7.5 hp centrifugal water pump through a big gun with 4″ PVC. It is pumped over a mile. This is only possible because there are no solids in the water, thanks to Key Dollar Separator.”

– Bob Nix

“In order to keep the Department of Environmental Quality satisfied after citizen complaints of the odor from the lagoon, lime treatment had to be applied until the odor was under control. Three years ago they put in two Key Dollar Micro-Screens and have not used lime since and have NO BAD ODOR SMELL! All their cannery water is pumped three miles out of town.

The Key Dollar machines operate using water it cleaned to clean its own screens – NO OTHER WATER NEEDED! They operate automatically. They turn on when the water comes on and turn off when the pump stops. The solids removed are spread on fields nearby and are not allowed to spoil. They can be spread on pasture, new cut hay or on ground to be cultivated. Neil Michael said he would be pleased to talk to anyone who had or has lagoon odor/smell problems.”

“The Key Dollar Separator is working wonderfully! We can’t believe how much solids are being retained and not going into the pond.”
