Some methods for making a granular material comprise crushing demetallized slag particles with one or more crushers and screening the crushed demetallized slag particles with one or more screens to separate the demetallized slag particles into two or more fractions, the granular material comprising at least one of the fractions of the demetallized slag particles. Prior to the crushing, ones of the demetallized slag particles having a size that is less than or equal to 2 inches can account for at least 90% of the demetallized slag particles. An iron-compound content of the demetallized slag particles, by weight, can be less than or equal to 10%. Crushing and screening can be performed such that ones of the demetallized slag particles of the granular material having a size that is less than or equal to 1.25 mm account for at least 90% of the demetallized slag particles of the granular material.

A crushing apparatus includes a tank including a first aperture and a second aperture, a first blower around the first aperture, a grinder disposed within the tank, a separating device including a first hole connected to the second aperture, and a second hole, and a second blower disposed around the second hole.

An apparatus for processing materials includes a chamber within which frequency turbine plates rotate relative to a circumferential wall having diametrically opposed portions which are asymmetric relative to each other. The circumferential wall with asymmetric arrangement in this manner promotes the generation of pressure differentials and interference wave phenomena when plates are rotated relative to such asymmetric arrangements, and thereby facilitates materials being processed through the associated apparatus. One suitable form of the apparatus comprises a pressure interference wave mill suitable for processing materials, such as slag.

A method for separating composite materials and mixtures, in particular solid-material mixtures and slags, and to a device for carrying out said method. The method for separating composite materials and mixtures comprises the step of transporting the composite material or the mixture through a separating device. The composite material to be separated or the mixture to be separated is excited by mechanical impulses as it passes through the separating device and is thereby separated. The device (1) for carrying out the method comprises a drive unit (21) for driving a rotor element (32), which is connected to a bearing/shaft unit (22) and which is part of a rotor unit (31). The rotor element itself has at least one rotor tool (33) and each rotor tool has at least one rotor tool component (34) and is surrounded by a stator element (42), which is part of a stator unit (41). The stator element itself has at least one stator tool (43) and each stator tool has at least one stator tool component (44). The rotor element and the stator element are substantially cylindrical.

A crusher having a substantially tubular casing, closed in an upper region by a cover and in a lower region by a base. The crusher also includes a rotating shaft, which is internal and coaxial to the casing, with multiple supporting elements, each element for supporting a number of crushing elements, being keyed to the shaft. The crushing elements have circular trajectories with a circumference that at least partially increases from the upper region toward the lower region of the crusher.

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.
