In recycling operations, hydraulic oil serves as the critical lifeblood of Vermeer equipment. Recycling machinery experiences unique operational demands that require specialized hydraulic performance. The hydraulic system not only transmits energy through fluid movement via the pump, but also provides essential lubrication for moving components, manages heat dissipation while processing and sizing materials, and controls contaminants like acids, varnish and air that can accumulate in recycling environments.
Hydraulic fluid properties can vary greatly from product to product. While there are only a few common base stocks for hydraulic oils, additives vary from each supplier. These additives, as well as different oil grades, create unique performance and cost differences between hydraulic oils.
A good hydraulic oil formulation for recycling applications can be just as, if not more, complex than the components that rely on it to run. That’s why most component manufacturers have distinct oil specifications. For instance, Vermeer Hy Power hydraulic fluids is engineered to optimize component performance in recycling equipment like trommel screens, horizontal grinders, tub grinders and low speed shredders — taking the guesswork out of selecting a hydraulic fluid.
Enhancing recycling productivity through optimal hydraulic performance
Vermeer Hy Power hydraulic oils deliver specialized protection for Vermeer recycling machinery, making them the ideal choice for equipment processing varied materials from wood waste to construction debris. These premium formulations are specifically engineered to withstand the extreme conditions of recycling operations where equipment may run for extended periods handling abrasive materials. With superior resistance to breakdown, these oils help extend service intervals between changes — a crucial advantage for recycling operations where maintenance downtime directly impacts production targets.
Matching hydraulic oils to recycling applications
It all starts with the right oil viscosity. Oil viscosity refers to how easily an oil pours at a specified temperature. The correct viscosity grade needs to be selected for the machine and the temperature. The appropriate viscosity provides hydrodynamic film protection which prevents metal-to-metal contact. Too low of viscosity increases wear and inefficiency from internal leakage, while too high of viscosity decreases efficiency and can cause starting issues.
The hydraulic oil must also have the correct viscosity index for recycling applications. The viscosity index is a measurement of a hydraulic fluid’s resistance to losing viscosity at increasing temperatures. Two oils with the same viscosity grade can have different viscosities at the same operating temperature — a crucial consideration for equipment like trommel screens and grinders.
Testing determines the right formulation for recycling equipment
Wear protection in hydraulic components and gear scuffing characteristics vary by formulation. Thermal stability, hydrolytic stability, filterability and air release are all determined by the specific formulation — factors that directly impact the performance of recycling machinery.
The right combination of these characteristics determines the best oil for specific recycling equipment. Engineers use industry-standard tests to determine the benchmark for each characteristic. Comprehensive research shows that Hy Power hydraulic fluid is optimized for high performance and to help protect Vermeer recycling equipment, including trommel screens, horizontal grinders, tub grinders and low speed shredders.
Avoid mixing oils in your recycling equipment
When topping off oils in the field, it may be tempting to use a hydraulic fluid that is conveniently available. However, you should avoid doing just that. Many hydraulic oil additives are not compatible with those from different oils. Don’t mix Hy Power hydraulic oil with other brands, as it could have negative impacts on machine performance and warranty coverage.
Selecting a hydraulic oil that meets all of the criteria for recycling applications is a complex task. Vermeer engineers have done all the homework for you, providing an optimized solution: Hy Power hydraulic oil. Take the guesswork out of hydraulic oil selection to drive uptime and help protect your recycling equipment investment.
