摘要： Provided is an ore crushing method capable of efficiently crushing iron ores that are difficult to finely crush. The ore crushing method includes coarsely crushing the iron ores to reduce the proportion of particles with a particle size of greater than or equal to 1 mm, and then finely crushing the iron ores to increase the proportion of particles with a particle size of less than 63 µm. The average pore size of the iron ores is preferably less than or equal to 10 µm, the proportion of the particles with a particle size of greater than or equal to 1 mm in the iron ores is preferably greater than or equal to 30 mass%, the iron ores are preferably coarsely crushed so that the proportion of the particles with a particle size of greater than or equal to 1 mm becomes less than or equal to 20 mass%, the iron ores are preferably finely crushed so that the proportion of the particles with a particle size of less than 63 µm becomes greater than or equal to 70 mass%, and the iron ores are preferably finely crushed with a wet ball mill. A pellet production method is also provided that includes granulating a raw material, which includes the iron ores crushed with the ore crushing method, into pellets.

摘要： The invention relates to a method for synthesising compounds, wherein solids are reacted with one or several gases, wherein the solids are ground in the presence of the gas above the atmospheric pressure. Preferably, a mill comprising a milling chamber (1), which receives the material which is to be ground (10), is used in order to carry out said method. The milling chamber (1) can be closed in a pressure-tight manner in relation to great internal pressure (P1).

摘要： A system for recovering ferrous metal components from waste materials includes a first magnetic separator (14) for magnetically separating ferrous metal components from waste material and an impacting device (16) for dislodging residual waste material from the surface of ferrous metal components separated by the first magnetic separator (14). The system may also include a second magnetic separator (54) following the impacting device (16), a water washing system (58) for cleaning ferrous metal components retained by the second magnetic separator (54), a ferrous metal collection station (60) and a waste material collection station (64). The impacting device includes a solid wall rotatable drum (22) having at least one radially inwardly projecting protuberance (46) on its interior surface. As the drum rotates, the protuberances (46) lift the ferrous materials separated by the first magnetic separator (14). Repeated impacts of the ferrous material with the interior surface of the drum (22) effectively dislodges waste material from the surface of the ferrous metal components without comminuting the ferrous material or subjecting the drum to aggressive wear and tear.

摘要： A gas swept tube mill has a rotary shell (1) supported on a bearing (5) by a slide ring (3), which is reinforced by a stiffening web plate (4). Ground material and gas pass out of the mill shell through a sieve plate (10) and openings (8) in a frustoconical connecting section (12) into a stationary casing (9). The wider end of the section (12) is of similar diameter to the shell (1), to which it is fastened, and the narrower end of the section (12) is fastened to a drive shaft (7) for rotating the shell (1).

摘要： The invention relates to a method for grinding materials in a rotating drum by ferromagnetic grinding bodies and can be used in the processes of the preparation of raw material for beneficiation, as well as in construction, chemical and others industries. The essence of the invention is that the grinding of the materials is carried out in a rotating drum, partially filled with ferromagnetic grinding bodies, wherein the grinding bodies are affected by the magnetic force of at least one electromagnet, mounted on the drum, and the magnetic field is formed by separate pulses in the quantity of not less than two, wherein the first pulse is divided into a number of shorter pulses. In contrast to the prototype, the first pulse is characterized by alternating-sign magnetic field, it is fed at an angular position of the electromagnet from -60° to -30°, where the central angle begins from a vector directed from the axis of rotation of the housing vertically downwards, the second pulse is characterized by constant magnetic field, it is fed at an angular position of the electromagnet from 0° to +30°, and its feeding is stopped at an angular position of the electromagnet from 110° to 165°. The technical result is the improvement of the energy efficiency of the process of grinding materials in ball mills.

摘要： The invention relates to a tubular mill. The aim of the invention is to provide a light-weight tubular mill that is easy and inexpensive to produce. For this purpose, partial lengths (10 to 13) of the tubular mill shell are screwed with thin-walled sheet metal segments (15) distributed across the periphery. Flanges (19, 20) are formed onto the abutting faces of adjacent segments, which flanges are especially rendered rigid by edging the plate edge. The flanges of adjacent segments coming to rest in the longitudinal direction of the mill tube are screwed together. Flanges (25, 26) are formed onto the two other faces of the segments (15) opposite each other, which flanges are especially rendered rigid by edging the plate edge. The flanges of adjacent partial lengths combined to one flange ring each are braced with each other via bracing elements.
