Pellet Specification,
Storage & Delivery

To determine the length of auger
required the following factors must be
determined
a) Difference in height between the
ground/floor level (on which the
store will stand) and the floor level
(on which the hopper will stand).
b) Horizontal distance between the
back of the hopper and the store.
If the store is to be situated outside this
will be
a) the distance from the rear of the
hopper to the inner face of the wall
b) the thickness of the wall
c) the distance to the store from the
outside face of the wall.
Refer to Figure 3-3 for further details.
Using the following table select the
required length of auger based on the
above dimensions. Always select the
next size up of auger.
3.2.3 Bulk Pellet Feed Auger
When installing a bulk pellet store with a
bulk pellet feed auger, consideration
must be given to the position of the
store in relation to the hopper as this
will dictate the length of the auger.
The length of the pellet feed auger,
supplying pellets from the bulk store, is
limited to a maximum of 6 metres in
length, as a longer auger can damage
the pellets.
Grant UK offer a range of eight bulk
pellet augers, from 2.5m to 6m in
length in 0.5m steps, as given in the
table below:
!
NOTE
Each bulk pellet supplier has clear
guidelines on the requirements of a
bulk storage hopper used to store
their pellets, together with
requirements on positioning, access,
and minimum deliveries.
ALWAYS check with the pellet
supplier you wish to use BEFORE
installing a bulk storage system.
