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.
