Provided are methods and apparatus for crushing clay, transporting clay, and processing clay. In examples, provided are movable truss conveyor support apparatuses, movable crusher picker apparatuses, picker shaft rakes to clean picker shafts, adjustable hoppers, and tracked crushers. In an example, provided is a crusher including (i) a crusher frame, (ii) a crusher subframe movably suspended from the crusher frame, (ii) a rotary bearing fastened to the crusher subframe, (iv) a rotatable picker shaft rotatably supported by the rotary bearing and adapted to rotate relative to the crusher subframe, and (v) at least one picker fastened to the rotatable picker shaft.

The invention relates generally to a mixing system for mixing a dry material with a liquid. The mixing system includes a supply of dry material and a supply of liquid. An infinitely variable metering device meters the dry material into the liquid. A sensor senses the ratio of dry material to liquid. The sensor is operatively connected to the metering device to control the metering device to obtain a desired ratio of dry material to liquid. The dry material is dispensed volumetrically by volume of liquid to form the desired ratio of dry material to liquid.

A crushing device includes a horizontal shaft impact crusher having an impeller rotating around a horizontal shaft and at least one curtain against which material may be crushed. The crushing device further includes a first feeding device for feeding a first type of material to be crushed to a crushing chamber of the horizontal shaft impact crusher. A second feeding device feeds a second type of material, having a smaller average particle size than the first type of material, to the crushing chamber simultaneously with the first feeding device feeding the first type of material to the crushing chamber. A mixing arrangement for at least partially mixes the first and the second types of materials with each other before bringing them into contact with the impeller.

A device for processing feed material, with a housing enclosing a processing space in which a rotor rotatable about the axis of rotation is arranged. The rotor has a rotor disk at which circumference a plurality of axially disposed impact plates is arranged uniformly distributed. A coaxially arranged processing path surrounds the impact plates while maintaining a working gap. Via a material inlet, the device is fed in the axial direction with feed material centrally ending in the processing space, which upon deflection in the region of the rotor disk is fed in the radial direction to the working gap. To ensure complete and gentle processing of the feed material while maintaining its original taste, smell and color, the processing path is part of a basket rotating about the rotational axis.
