The bell mixer method may sound a very long-winded and time-consuming way of mixing,
but once you get the hang of it it's possible for one person to keep two mixers constantly
running - as long as the materials are close to hand and you have a good pressure on your
water supply. You can get into a rhythm so that while the mixer is turning you're filling
buckets ready for the next batch. One mix takes about 5-10 minutes, and it is possible to
mix around 2-2.5m 3 of hempcrete in a day.
The point noted on page 201 about finding a balance between the speed of mixing, ferrying
and placing hempcrete, applies here. But suffice to say that if you have chosen to use a bell
mixer, you have already decided that you are doing a job where large quantities of mix are
not required quickly.
