A type of REFINER
consisting of a conical plug which fits into a
matching conical shell. The outside of the plug
and the inner surface of the shell are fitted with
knives or bars. The plug is pushed into the shell
to the point where the knives or bars of each are
almost touching. When fibrous stock in solution
enters the shell, usually at its smaller end, the
knives or bars of the rotating plug and stationary
shell mascerate the fibrous material and help
reduce it further. (17 )
