| The "Eureka Aspirating Separator"
has now been installed in one corner of the Garner and is used on Open Days for initial grain cleaning. Made in America by S. Howes of Silver Creek, New York, it came to New Hall Mill from Rock Mills at Leamington Spa after they closed. |
 |
| A new grain hopper has been constructed,
filled from the top with grain lifted from the ground floor by the
sack hoist. Powered via a line shaft, pulleys and a canvas belt from
the ground floor, the Aspirator is, apart from the mill stones, the
only machine to be powered by the waterwheel. The belt drives a large internal fan to produce a strong air current. |
|
| When the hopper lever is operated, grain falls from the hopper into the strong updraft of air and the 'stives', consisting of the chaff and any other light rubbish, are sucked away from the falling grain. Some are retained in a central waste section but the lighter portions pass through the fan and are collected in the 'stive room', a separate area enclosed by sacking (not shown). The cleaned grain falls down a chute to the Winnower on the Stone Floor. | |
