Fintan, then pointed out, “The difference on this machine is we have extended the collection conveyor right under the feed hopper so any spillage from the feed hopper will all be collected under the main feed belt which feeds the wash plant; this has minimised any spillage around the machine. The machine has also been vertically repositioned to provide better access all around the machine. Furthermore, the incorporation of jacking legs on the screen box and a small hydraulic powerpack to raise the screen box enables the changing of the mesh on the bottom deck or to fit new skirting rubbers is easily accomplished simply by pulling a lever allowing the whole box to raise up!”
Material is then fed up with a wash box which is fully enclosed and fitted with a dead box so that material fills and wears on material and then pours evenly onto the 16 x 5 double deck rinsing screen fitted with polyurethane modules with 50mm aperture top and 5mm aperture bottom decks.
All material coming off the top deck is a washed 80mm product and the material that screens off through the bottom deck is sand with the mid-size product fed into the logwasher.
It is quite apparent that a lot of time and effort has been put into all the transfer points by the Tyrone International Engineering Team, minimising overspray and water leaks ensuring an efficient clean plant.
A unique T-Scrub Logwasher:
At this point a horizontal conveyor handles the 80mm material and feeds into the T-Scrub 1600 logwasher.
Fintan commented, “the T-Scrub is unique in that it provides full access via doors which are hinged from the centre of the roof on the hull along both sides for easy plant maintenance. Within these doors inspection hatches are incorporated to enable inspection whilst running. All the maintenance is done from the side of the logwasher without any requirement to remove guards.”
After the material has been scrubbed through the logwasher it is discharged over another dead box to reduce any wear and then feeds onto a large rinsing screen which washes out any remaining sand ensuring that the stone is absolutely clean before it is segregated.
All clean aggregate is then fed to a T-Screen 125 where it is split into 3 clean aggregates 10mm, 20mm and 40 mm and stockpiled via integral conveyors.
2-grade sand plant:
Under the logwasher is a large self-regulating pump tank which regulates the height of the water dependant on the amount of solids being processed, here all the water, silt, clay, and sand plus any -5mm trash material that has washed
through the screen is collected.
