CEB Press IV
This version of the press builds Version 3 and makes improvements towards greater ease of use and quicker fabrication. The top ten most substantial improvements are as follows:
- Hopper Design – The hopper will now catch 99% of the soil dumped into the grate due to reduced hopper aperture, and improved cut design of the hopper panels from a single 5x10 sheet of steel
- Hopper Interface Saddle – A sheet metal saddle now cradles the hopper and allows a tighter funnel for soil to fall into the compression chamber
- Compression Chamber – The long sides of the compression chamber can now be cut out of ½” steel with ½” flanges welded on as support contributing to flatter bricks.
- Primary Structural Improvement – Several structural members of the press are now built out of 3x6x3/8” steel rather than 2x6 “heavy” U-channel improving overall rigidity.
- Cylinder Press foot – The press foot which presses the bricks is now specified out of abrasion resistant (AR300) steel increasing durability.
- Press Cylinder – The press cylinder is now specified with a bare shaft on which the press foot is pinned rather than welding (as in the previous design)
- Hopper Piano Hinge – The hinges holding the walls of the hopper together are now continuous (aka "piano") hinges rather than a series of door hinges
- Drawer – The drawer is now designed out of nearly all ½” steel plate and could be cut out of a small sheet using CNC technology.
- Drawer supports – The drawer is now supported by 4 cam followers which are held by a modular drawer support assembly
- Grate attachment – The grate is now attached to its structural support using a continuous hinge so the grate can be opened upward like a hatch to maintain soil flow when blockage occurs.
