CEB Press Design Rationale, Product Ecology

Design Rationale

The design objective for the OSE CEB was to produce the simplest, high performance, lifetime design, design-for-disassembly machine - made with stock and minimum-machined parts - at the lowest possible cost. The design follows OSE Specifications

The OSE CEB press is a vertical press, where soil falls by gravity directly from the hopper into the compression chamber. The main cylinder compresses soil, and the soil loading drawer closes/opens the compression chamber and ejects bricks from the machine. ( Hydraulic Design)

Results and Improvements Made

• See machine specifications from last year.
  • Note on the brick pressing rate: maximum of 16 thin bricks per minute with 54 hp, without using grate shaker
• The main addition to the CEB machine design since last year is the increase of machine height from an 8" to a 12" main pressing cylinder, so that the resulting bricks are (2"-6")x6"x12" as opposed to the (2"-4") bricks.
  • This means the pressing rate is reduced but larger bricks are made

Improvements Needed

• The machine is currently moved into place by forks, but a trailer will be added to improve mobility.
• Sides will be added to the grate to prevent soil from falling off the grate
• Flat bar will be used instead of rebar as the grate to facilitate soil falling through the grate.
