Jesson static junior MK 2 paver/brick machine


The Static Junior MK 2 Machine is an all-steel construction, designed to produce smaller sized concrete building components, such as pavers and bricks, for which the moulds can be interchanged. During each production cycle, six rectangular or interlocking pavers (20 x 10 cm x any thichness up to 14 cm ) or eight bricks of 22x 10.4x7.5cm or 19x9x9cm are moulded on a wooden pallet. Special moulds can be made to order.

The machine, which is operated in a stationary position, but has two wheels to move around the brickyard, is powered by a 1.1 kW electric motor, running on single or 3-phase electricity (220 or 380 volts).

Operating the Static Junior MK 2

The Static Junior MK 2 is operated principally in the same way as the Lightning Static, except that the latter is also able to make hollow blocks, has a higher output rate for its bricks and pavers and is not equipped with wheels for moving around the brickyard, as in the case of the Static Junior.

With the compactor raised, the moulds are filled with concrete, vibrated for 1 second, the mould refilled and the excess material smoothed off level with the mould top. The compactor is pulled over the mould and released by turning a handle. After vibrating for about 5 seconds, the mould box handle is pulled down fully and the compactor handle reengaged, releasing the newly made products from the mould. A new pallet is inserted by pushing the loaded pallet out of the machine. While it is being carried away for curing, the mould box is lowered onto the new pallet and the production cycle repeated.

300 Litre Trough Mixer

The family of Jesson machines includes a trough mixer, which is capable of mixing wet, slurry concrete, as well as liquid and granular like chemicals, paints, fertilizers etc. The mixer, which was originally designed for use in the brickmaking industry, has a horizontal shaft around which the mixing paddles rotate. The mix is discharged by gravity through a door at the bottom of the trough, so that a wheelbarrow placed below can be easily filled.
