Description
The ELLSON Blockmaster which is being manufactured in India
since 1959, is one of the oldest soil block presses that is still being
produced. The press is a robust all-steel welded construction, and is capable of
taking on interchangeable moulds to produce blocks, bricks and tiles of
different sizes.
The Blockmaster has a lever-linkage toggle mechanism and high
compaction is achieved by its high lever ratio the forceful closing of the lid
and "jumping-pull" of the lever.
An important feature of the machine is the height of the mould
off the ground, which helps to reduce back-ache from bending down to remove the
ejected blocks. The operation of the lever only on one side of the machine is a
further advantage.
Training courses on soil block production can be arranged by the
manufacturer at the works in Rajkot.
Operating the ELLSON Blockmaster
A triangular scoop is provided for each corresponding mould
size, to ensure that the mould is always filled with the same quantity of soil.
When the mould is filled, the lid is slammed down and held in place with a
clamp.
The two operators on the lever now swing back to complete the
compression stroke or "pull down". This should require some effort to obtain a
well compacted block. If the lever offers no resistance, the mould is not
sufficiently filled, if the required effort is too great for the two operators,
the mould is overfilled, in which case it must be refilled with a fresh soil
mix.
Once the pull-down is completed, the clamp is released and the
lid opened. By further pressing down of the lever, the block is ejected clear
off the top of the mould, so that it can be picked off and carried to the curing
place.
