Parry/ITW Clay Pantile production plant

Description

The Clay Pantile Production Plant is a further part of the ITW small-scale production plant and handling system for burnt clay building materials. It is a cost-effective, simple alternative to the traditional methods of clay roof-tile production. The production of clay pantiles with the Parry/ITW plant is a purely manual operation, in which only local materials are processed.

The main equipment is a preparation table, on which a roller press and tile stand are mounted, and on which the raw clay is shaped to pantiles and placed on special forms for drying. Furthermore a steel box with a cutting frame is provided together with a bow cutter to cut uniform clay bats, as well as a shaping tool into which the bats are placed. Most of the ITW equipment used for brick-making (eg clay crushers, portable clay hoppers, carrying racks 3-wheel trucks) are also designed for use in pantile production.

The approximate dimensions of the finished clay pantile are 350 x 270 x 11 mm thick. The effective coverage is approx. 270 x 230 mm (about 16 tiles per square metre of roof surface).

How a clay tile is made

1. A clay bat is thrown into the cutting frame. The excess is cut off with the bow cutter and re-used.
2. The outer box of the frame is removed by sliding upwards.
3. The large bow cutter is used to cut the clay into bats. The frame has slots to guide the cutter.
4. The clay bat and the shaping tool is dusted with sand and the bat is laid on the shaping tool. The surface is dusted with sand to prevent sticking.
5. The shaping tool with the bat on it is rolled through the roller press. This forms the bat into the correct tile shape and thickness.
6. Tile and shaping tool are placed on the stand and the trimmer is drawn along the edges to cut off the excess clay.
7. The drying form is placed on top of the tile, and holding the two together is lifted and fumed over.
8. The shaping tool is removed, leaving the tile in position on the drying form.
9. Then it is transferred to the carrying rack.
10. When full, the carrying rack is picked up by the 1/4 tome truck and taken to the drying racks.
11. The forms are then placed on the covered drying racks where they harden for one or two days.
12. Then they are taken to the drying ground where they are removed from the drying forms and stood on edge for final drying before firing.
