Abstract
Apparatus 12 for treating a body 16 of an input material comprising an extrudable part and a non-extrudable part comprises at least one extruding assembly 14.1. The extruder 22, 24 for converting the extrudable part into an extruded part. The extruder is located downstream of an inlet 28 for the input material to the passage and upstream from a first outlet 30 from the passage for the extruded part and a second outlet 32 from the passage for the non-extrudable part. The apparatus further comprises a mechanism 34 cooperating with the passage 20 for directing the extruded part to the first outlet 30 and the non-extrudable part to the second outlet 32.
Claims16
Apparatus for treating a body of an input material comprising an extrudable part comprising a sludge or clay and a non-extrudable part, the apparatus comprising:
- at least one extruding assembly comprising a body defining a passage for the input material and an extruder for converting the extrudable part into an extruded part;
- the extruder being located downstream of an inlet for the input material to the passage and upstream from a first outlet from the passage for the extruded part which first outlet is defined in a sidewall of the passage and a second outlet from the passage for the non-extrudable part which second outlet is downstream from the first outlet;
- and
- means for receiving the extruded part which means comprises a conveyor in cooperating relationship with the first outlet for conveying the extruded part.
A method of treating a body of an input material comprising an extrudable part comprising a sludge or clay and a non-extrudable part, the method comprising the steps of:
- moving the input material along a passage;
- extruding the extrudable part and presenting the extruded part through a first outlet from the passage which is defined in a sidewall of the passage;
- whilst extruding, separating the non-extrudable part from the extrudable part;
- and
- making the non-extrudable part available downstream of the first outlet.
