The Northstone plant was designed to produce concrete for the manufacture of roof tiles.
It incorporated a 3 metre output mixer concrete feeding a  press

The plant design included a 40 Ton receiving Dump Hopper complete with safety grid which was to receive aggregate from tipping lorries.
From there the aggregate was conveyed to an enclosure which housed a vibrating screen. The enclosure enabled maintenance of the screen and the conveyor.
The screened aggregate was then conveyed to the top of the bins by means of a lattice conveyor.  On top of the bins a rotating conveyor was used to allocate the aggregate to its particular bin.  The bins were of cylindrical design to help with discharge and contamination issues. There were 3 off 80T bins and 2 off (40T) bins. The top of the bins were floored to help reduce dust and also enable maintenance to be carried out on the conveyors.
Feeder conveyors were used on the outlets of the bins to enable accurate weighing of the material. The conveyors were also reversible to exclude any unwanted material.  The aggregate was weighed by means of a weigh hopper.  The hopper was capable of weighing batches up to 2.25m3 and discharged onto a lattice conveyor which conveyed the material to the mixer platform.

The plant also included 2 off 100T cement silo’s.  The silo’s were supplied complete with air filters and safety devices and allowed full access for maintenance. The cement was fed to a weigh hopper located in the mixer platform via 2 screw conveyors.

The mixer platform was deigned to house all of the holding hoppers, mixer and wet batch hopper.  The aggregate holding hopper and the cement weigh hopper help the aggregate above the mixer. Both hoppers discharged straight into the mixer allowing the batch to be ready for the mixer as soon as it was required.
The mixer platform was fully cladded and came complete with full maintenance access and dust extraction system.

The mixer discharged the material into a wet batch hopper which was capable of holding up to 1.5 batches. The material was removed from the hopper by means of a flat conveyor and fed onto a machine feed conveyor.  This meant that a steady supply of concrete could be transferred to the press without any breaks in the material.

The plant came complete with full control system, all safety devices, and flow aid equipment.

Steelwork used for the plant was all shot blasted to make sure all rust was removed and painted to the highest standard,

This Turn-key plant was erected by our own site engineers and  fully commissioned, ready to make tile material for the customer.
