A pulverizer comprising: a housing having top and bottom ends, an inlet located towards the top end for receiving input material to pulverize and an outlet located towards the bottom end for discharging pulverized material from the housing, the housing including a housing sidewall defining an interior chamber and having a central housing axis: a rotatable shaft extending along the central housing axis: a plurality of rotor hub assemblies mounted to the shaft, each rotor hub assembly including a rotor hub and a plurality of rotor arms extending outwardly from the rotor for forming an airflow revolving about the central housing axis within the interior chamber, wherein at least one of the housing and of one or more of the rotor hub assemblies is selectively reconfigurable between a plurality of configurations to adjust at least one parameter of an output flow of the pulverized material at the outlet.

An abrasion resistant wear plate is mountable within a rotor or a vertical shaft impact crusher to protect the rotor from material fed into the rotor. The wear plate includes a main body that mounts and supports at least one abrasion resistant insert to define, in part, a contact face over which feed material is configured to flow.

The present disclosure relates to a vertical shaft impact crusher comprising a rotor having a rotor protection layer which consists of particles of objects to be crushed. The rotor includes at least: a rotor upper plate comprising a rotor upper plate hole, which is an inlet for the object for crushing which is inserted into the rotor; a rotor lower plate disposed to be separated from the lower portion of the rotor upper plate; a rotor upper plate; a rotor side wall disposed between the rotor upper plate and the rotor lower plate and coupled to the rotor upper plate and the rotor lower plate, the rotor side wall being disposed at a position spaced from the rotation center of the rotor; and a circular hole which is formed on the rotor side wall and is an outlet for the object for crushing accelerated by the rotor to come out of the rotor.

A mineral material crusher and method of operating a mineral material crusher that includes: a body, a rotating crusher element, a drive shaft arrangement that supports the rotating crusher element to the body and to rotate the rotating crusher element, and a motor including a rotor for driving the drive shaft arrangement. The motor is formed inside the rotating crusher element and the drive shaft arrangement is configured to form of the rotor a rotating axle that is rigidly coupled with the rotating crusher element and capable of leading torque from the rotor to the rotating crusher element for rotating the crusher element around the drive shaft.

Dynamic crusher for treading fruit, particularly grapes, with a treading chamber having, when considering the direction of the path followed by the fruit in the crusher, an upstream fruit-introduction opening, a downstream discharge opening for discharging the must that results from the treading, a rotary ejector that allows kinetic energy to be imparted to the fruit introduced into the treading chamber, and allows the fruit to be cast against a fixed fruit-bursting wall, wherein the rotary ejector is mounted such that it can rotate about a vertical axis and a fixed fruit-bursting wall is positioned around the rotary ejector or facing the peripheral edge thereof against which fruit is cast, rotation of which allows the fruit to be cast, under the effect of centrifugal force, against the fixed fruit-bursting wall, causing the fruit to burst. A method for dynamically treading fruit using such a crusher is also disclosed.

A vertical shaft impact crusher feed tube arranged for protecting a rotor feeding opening of a feeding funnel of a vertical shaft impact crusher. The feed tube includes a tube portion via which material may flow from the feeding funnel and vertically downwards into a rotor. The tube portion has a first width at a material inlet, and a second width at a material outlet, wherein the second width is larger than the first width.

Described herein is a combine harvester having at least one impact mill for devitalising weed seeds in a crop while the crop is being harvested by the combine harvester and a power take off shaft. The impact mill of the combine harvester includes an inlet for material to enter the mill, an impact mechanism arranged to rotate about a rotation axis, an outlet for discharge of impacted material, a drive system coupled to the power take off shaft, one or more torque sensors, and a data processor arranged to process information provided by the one or more torque sensors wherein the data processor is programmed to calculate throughput of material processed by the impact mill. Also described herein is an impact mill system capable of mounting on a combine harvester for devitalising weed seeds in a harvested crop.

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.
