The KISS Principle IIl
Hydraulic System

Hydraulic systems are particularly subject to becoming quite complicated due to the many options and possible hydraulic circuits available. There are a large number of system providers with good engineers and sales personnel, all with a fine product and a need to sell for a living. There becomes a tendency to over design, just to be sure.

Providing the best combination of hydraulic components capable of performing all functions required, reliably with a long life and at the lowest overall cost while remaining easy to service is my goal. I believe that you, our customer is best served if I follow KISS Principles and provide you with such a system. After all, if you need to learn about fancy controls, sensors or electronics to service your new machine, you will not be focusing on your goal of providing your customers with select materials at a good profit.

Orbital Action screening plants employ very simple circuitry, beginning with providing an individual pump for each primary circuit (working component) of the machine. The feed hopper and the screen dish have variable volume pumps while the conveyors have constant volume pumps, all stacked together as a four pump assembly to be driven with one drive.

Following the pumps, each of four circuits execute an individual task. The two variable volume pumps only pump the required volume of oil. The two constant volume pumps are well balanced to the loads expected.  There is no hydraulic oil being pumped that is not used to power a required function. No hydraulic power is wasted through pilot circuits, compensating controls or valves. Heat build up is minimal as nearly all of the engine power introduced into the system is used to perform work.

Continued next week.

Happy screening,
