MicroTrac Baseline Calculation

Introduction

The basic design rationale for MicroTrac hydraulic pump (and engine) size requirements is the ability to power the Liberator 2 CEB press to the extent that it can produce 6-8 bricks per minute. This indicates 360-480 bricks per hour, or between 2880-3840 bricks per 8 hour work day. Wow. This involves a 2 person team, one person running the LifeTrac hybrid Soil Pulverizer, and the second person stacking bricks. This improves upon the 500 brick per 8 hour day sustained production rate that we ordealed last year with a typical 2 person team. We still got the CEB workshop addition built - under the worst possible conditions. It was a worthwhile experiment in that we now have a spacious workshop environment - and with the planned sCEB floor and other improvements, we will not complain. It's time to move on to the Solar Village. Now seeking collaborators for design assistance.

Pressing Rate Calculations

based on the 12 gallon per minute hydraulic pump specified for MicroTrac - what is the possible, baseline brick production rate?

• Start with a baseline of 12 gallons per minute (GPM) at 2500 psi (see calculations at MicroTrac
• To calculate the number of bricks that can be pressed per minute, we start with the 5 inch diameter pressing cylinder.
• Convert the GPM flow rate to linear cylinder motion rate.
• 1 gallon = 231 cu in - [1]
