CEB Press Design + Function
The OSE CEB Press is a bottom press- blocks are pressed by the main cylinder from the bottom. A soil loading drawer loads soil into the compression chamber. Soil is loaded from the top of the machine using a tractor loader from one side of the machine. The blocks are ejected on the opposite side of the machine, away from the loading side - so that machine loading and unloading can happen safely at the same time. The blocks are pressed agains the surface of the soil loading drawer, and typical operating pressure for CEBs is 2200-2300 PSI to achieve proper compreesion. No advantage in block quality is obtained by running above this pressure.
The full sequence of pressing steps is found in this diagram:
The operating pressure of the machine is
The solenoid valve can handle up to 28 gallons per minute of hydraulic fluid flow at 3000 PSI.
The design is:
