#How do we know that a repeatable amount of soil and stabilizer will fall through the loading drawer aperture? Do we have a way to apply a force other than gravity to give better cycle to cycle repeatability? | |||
#How can we vary the ratio of soil to stabilizer in the field? Would the users be able to modulate the aperture size? | |||
#What would eject the material up and out of the chute after mixing is complete? How do we know all the material would be thrown out? | |||
#At what point is water incorporated into the mixing process? Is the water added to the soil beforehand? This soil would have a higher moisture content than the final mix would and this would lead to bridging in a hopper. Consider this when analyzing this point. | |||
#The mixing would take longer than a compression cycle. That is my intuition and it may be wrong. Would this one brick mix quantity be sent to an accumulator so that the brick press is not operating at a reduced speed? | |||
#Can we some way do the soil loading without an additional hydraulic actuator (or with a much less expensive cylinder)? | |||

Hey, here is my feedback on the first concept in question form:
- How do we know that a repeatable amount of soil and stabilizer will fall through the loading drawer aperture? Do we have a way to apply a force other than gravity to give better cycle to cycle repeatability?
- How can we vary the ratio of soil to stabilizer in the field? Would the users be able to modulate the aperture size?
- What would eject the material up and out of the chute after mixing is complete? How do we know all the material would be thrown out?
- At what point is water incorporated into the mixing process? Is the water added to the soil beforehand? This soil would have a higher moisture content than the final mix would and this would lead to bridging in a hopper. Consider this when analyzing this point.
- The mixing would take longer than a compression cycle. That is my intuition and it may be wrong. Would this one brick mix quantity be sent to an accumulator so that the brick press is not operating at a reduced speed?
- Can we some way do the soil loading without an additional hydraulic actuator (or with a much less expensive cylinder)?
- For Lime Blocks: A retention time is encouraged by texts on the subject, a time between mixing and compression. In what ways could our mixer accommodate this step?
These are my thoughts as of now. Thanks for reading.
