A method in which a stream of dry cementitious powder passes through a first conduit and aqueous medium stream passes through a second conduit to feed a slurry mixer to make cementitious slurry. The cementitious slurry passes through a third conduit and a reinforcement fiber stream passes through a fourth conduit to feed a fiber-slurry mixer which mixes the slurry and discrete fibers to make a stream of fiber-slurry mixture. An apparatus for performing the method is also disclosed.

A kneading apparatus has two rotary shafts mounted to undergo rotation in opposite directions at unequal speeds. Cubic-shaped kneading members having the same shape and size are detachably mounted to the rotary shafts so as to be arranged helically with an inverse helix from each other at a predetermined helical pitch and at predetermined angular pitch intervals for kneading an object during rotation of the rotary shafts. Each kneading member has side surfaces extending parallel to a rotational axis of the rotary shaft and front and rear surfaces extending perpendicular to the rotational axis. The side surfaces of each kneading member is curved in the shape of a concave. The rotary shafts are disposed close to one another so that tips of the kneading members on one of the rotary shafts enter into the concave curved surfaces of the opposing kneading members of the other of the rotary shafts without the opposing kneading members contacting one another during rotation of the rotary shafts.

An apparatus and method for processing a foodstuff comprises a closed conveyor path, a conveyor device, and a treatment chamber. The conveyor path includes an inlet and an outlet. The conveyor device is positioned within the closed conveyor path and configured to receive the foodstuff from the inlet. The conveyor device is further configured to convey the foodstuff along the closed conveyor path toward the outlet. The treatment chamber is positioned within the closed conveyor path downstream of the conveyor device for receiving the foodstuff from the conveyor device. The treatment chamber includes a rotatably driven first kneading shaft configured to collide the foodstuff within the treatment chamber.

A kneading apparatus has a housing and first and second rotary shafts mounted in the housing in parallel to one another for undergoing rotation about respective axes in opposite directions at unequal speeds to one another for kneading an object. The first and second rotary shafts have respective first and second stirring members arranged helically at a predetermined helical pitch and at predetermined angular pitch intervals, with the second stirring members being arranged with an inverse helix from that of the first stirring members. Side blocking plates disposed in the housing partially block the kneaded object and move it between the first and second rotary shafts. The side blocking plates are spaced apart from one another to provide a space above the first and second rotary shafts such that the kneaded object can pass through the space in the axial direction of the first and second rotary shafts.
