CEB Press 4

CEB Press IV

This version of the press builds of 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 in the previous design • Hopper Piano Hinge – The hinges holding the walls of the hopper together are now continuous or 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 of it using CNC technology. • Drawer supports – The drawer is now supported by 4 cam followers which are held by a modular drawer support assembly. See image below • Grate attachment – The grate is now attached to its structural support using a continuous hinge so the grate can be opened up like a hatch to maintain the soil flow when blockage occurs.
