A pin mill includes a rotor plate mounted on a shaft and having concentrically spaced-apart circular arrays of pins arise from an end face. The rotor pins interdigitate with complementary concentric arrays of pins arising from a face of a stator mounted on a door. The door swings open on a hinge mounted on two translator pins so that the door can translate the interdigitated pins before swinging open so that the pins arrays do not collide with each other while the door is opening. The rotor operates within a rotatable cylindrical screen which retains particles being broken up until they are small enough to exit. The rotor includes a circular array of vane knives which sweep closely within the screen and also entrain cooling air into the macerating volume of the mill. Oversized particles trapped in the screen also get cleared and split apart by the passing vane knives.

A method for controlling a crusher having a crushing tool and a vibratory conveyor (1) having a drive (5), includes capturing bulk material (2) in a capture region (4) using a sensor (3). So that, in the case of grains with an inhomogeneous grain size distribution, even large grains can be crushed with a constant crushing result without a risk of the crusher being damaged, an effective diameter d.sub.eff, which results from the largest diameter d.sub.max and the direction (9) thereof, transverse to the conveying direction (8) of a grain of the bulk material (2) is determined as the controlled variable in the capture region (4). If the effective diameter d.sub.eff exceeds a predefined power threshold value, the power of the crushing tool is increased and/or, if the effective diameter d.sub.eff exceeds a predefined switch-off limit value, the drive (5) is switched off.

An apparatus for destroying data storage devices comprises a shredder assembly, a hammer mill assembly, a chute mounted in an open communication with an interior of the shredder assembly and with an interior of the hammer mill assembly, the chute sized and shaped to transfer shredded remnants from the shredder assembly into the hammer mill assembly, a power drive assembly coupled to each of the shredder assembly and the hammer mill assembly, and a control assembly configured to operate the shredder assembly and the hammer mill assembly.

Various embodiments of horizontal shaft impact (“HSI”) crusher systems, methods and apparatus are disclosed herein. Some HSI crusher embodiments are provided an adjustable feed angle. Some HSI crusher embodiments are provided with an adjustable curtain position.

An apparatus for tearing meat is disclosed. The apparatus includes a gravity-fed hopper including at least one sidewall that forms a first opening configured to receive meat articles and a second opening configured to discharge torn meat articles. The apparatus includes a rotatable spindle element positioned at least partially within the hopper and downstream of the first opening. The rotatable spindle element includes a shaft having a longitudinal axis and a plurality of teeth coupled to the shaft, the teeth being spaced apart from one another. The apparatus includes a plurality of rods, which extend from the sidewall spaced apart from one another and which are interlaced with the plurality of teeth, and a motor coupled to the rotatable spindle element configured to rotate the rotatable spindle element to cause at least some of the plurality of teeth to rotate and pass between two different rods.

Provided is a non-belt automatic mechanized sampling system for a train, including: a working platform provided with a slide rail; a sampling mechanism slidably arranged on the slide rail and configured to collect materials from the carriage of the train; an integrated sample preparation component including a discharging mechanism and a feeder, a crusher, a constant mass dividing machine and a sample retention barrel arranged from top to bottom. The feeder transports the material to the crusher. The crusher crushes the material and transports the crushed material to the constant mass dividing machine. The constant mass dividing machine divides the crushed material into samples to the sample retention barrel, and the discarded material to the discharging mechanism. The discharging mechanism transports the discarded materials to the carriage.

The invention relates to a device (10; 50) for mechanically comminuting materials, including a vertically extending comminuting chamber (14) having an upwardly extending supply side (15) and a downwardly extending discharge side. The comminuting chamber is enclosed by an circular cylindrical and/or conical downwardly expanded comminuting chamber wall (12), and in which at least one rotor (16, 18) rotating about a vertical rotor axis (R) is arranged, which is provided with striking tools (38) that extend radially into the comminuting chamber, at least during operation. The rotors (16, 18) are held in a stationary manner with respect to a support base (20) of the device, and the comminuting chamber wall is supported on the support base. According to the invention, the comminuting chamber wall is held in place by way of a lifting device in the direction of the rotor axis (R) in a height adjustable manner relative to the support base (20). The lifting device (36) has a working position, in which the lower edge of the comminuting chamber wall (12) is arranged close to the support base (20) or to a part connected thereto, and a maintenance position, in which the lower edge (32) of the comminuting chamber wall (12) is vertically raised above at least one of the striking tools (22, 24). The invention allows easy maintenance and an uncomplicated exchange of the striking tools of the comminuting device.

A vertical shaft impact crusher feed hopper distribution device arranged for feeding material to be crushed to a rotor of a vertical shaft impact crusher. The feed hopper distribution device is arranged to be mounted in a feed hopper that feeds material to the rotor and includes a supply channel that forwards material from an inlet opening arranged adjacent to an upper end of the supply channel to a hopper bottom opening arranged in a bottom of the feed hopper and communicating with the rotor. The supply channel has a cross-section that widens along at least a portion of the distance from the upper end to a lower end of the supply channel.
