An apparatus for reducing the size of a solid material into smaller particles having an implosion chamber for containing the solid material and creating turbulence and ultrasonic soundwaves. The soundwaves generated by a flail propeller bounce off the chamber walls to create sound frequencies causing the expansion of moisture particles in the solid material leading to implosion of moisture particles within the solid material. The implosion thereby results in reducing the size of solid material, wherein a separating section that receives the smaller material from the implosion chamber channels the coarser particles back into the chamber to go through additional disintegration process. The rotation of the flail propeller within the chamber causes the moisture particles of the solid material to oscillate at high frequency and expansion that disintegrates the solid material. During this process, the moisture content is converted into vapor.

An impact crusher for grinding and separating solid material has a base and a rotor on the base having an upright shaft defining an upright rotor axis about which the rotor is rotatable and a plurality of vertically spaced and radially horizontally outwardly extending plates each having an outer periphery. A drum fixed on the base spacedly surrounds the rotor. An array of axially extending and angularly substantially equispaced replaceable ribs is provided on an inner surface of the drum. A respective plurality of impact hammers are angularly substantially equispaced around the outer periphery of each of the disks. Respective mounting pivots support the hammers on the outer peripheries of the plates for pivoting about respective hammer axes parallel to the rotor axis so that rotation of the rotor grinds material between the hammers and the ribs. Formations between the mounting pivots and the respective disks enable radial adjustment and fixing of the hammer axes relative to the rotor axis.

An impact crusher for grinding and separating solid material has a base, a rotor on the base having an upright shaft defining an upright rotor axis about which the rotor is rotatable, and a drum fixed on the base, spacedly surrounding the rotor, and formed by a pair of generally semicylindrical drum shells fitted together at a plane including the rotor axis. An array of axially extending and angularly substantially equispaced replaceable ribs is provided on an inner surface of the drum. A plurality of impact hammers are angularly substantially equispaced around the rotor and orbitable past the ribs on rotation of the rotor.

An impact mill (10) has an inlet (12) for material to enter the mill, an impact mechanism (16, 50) arranged to rotate about a rotation axis and being operable to pulverise the material after entering through the inlet, and an outlet (154) for discharge of pulverised material. Blockage sensors (Bj), vibration sensors V, torque sensors Tn, temperature sensors and proximity sensors may be selectively incorporated into the mill.

There is disclosed an apparatus 100 for reducing the size of a solid material into smaller particles including powder form comprising: an implosion chamber 3 for containing the solid material; and adapted for creating turbulence and ultrasonic soundwaves that bounce off the chamber walls at different angles to create sound frequencies of varying patterns; causing the expansion of moisture particles in the solid material leading to implosion of moisture particles within the solid material. The implosion thereby results to cavitation and reducing the size of solid material within the chamber 3 into smaller particles; a separating section A for separating the particles based on sizes; and channelling the coarser particles into the chamber to go through additional disintegration process; the implosion chamber 3 comprises a conical member 14, a static propeller 9 attached to at least one surface of the chamber 3 and a flail propeller 13 rotatably below the conical member 14 and static propeller 9; the flail propeller 13 and the conical member 14 being connected to an axis within the chamber 3. The rotation of the flail propeller 13 within the chamber 3 generating ultrasonic soundwaves that causes the moisture particles of the solid material to oscillate at high frequency and expansion that disintegrates the solid material. During this process, the moisture content is converted into vapour.

A rotor for a device for disintegrating feed material, comprising a drive shaft, a plurality of rotor disks mounted on the drive shaft, and disintegration tools arranged in the region of the outer circumference of the rotor disks. A holding flange is provided for each rotor disk for connecting the rotor disk to the drive shaft, wherein the holding flange is permanently connected to the drive shaft and detachably connected to the rotor disk. Devices for disintegrating feed material, in particular impact hammer mills, may thus be operated with a rotor, in which the risk of a shaking out and a lateral wandering of the rotor disks is largely eliminated.

Weed seeds are destroyed in the chaff from a combine harvester by repeated high speed impacts caused by a rotor mounted in one of a pair of side by side housings which accelerate the discarded seeds in a direction centrifugally away from the rotor onto a stator including angularly adjustable stator surfaces around the axis. Thus the discarded seeds rebound back and forth between the rotor and the stator to provide a plurality of impacts. The destructor is mounted on a suitable drive shaft within the straw path and the chaff and weed seed material is carried from the rear end of the sieve to the destructor on the straw chopper by one or more fans driving the material through a transfer duct.
