摘要:
The present invention relates to a crushing device comprising a jaw crusher provided with two jaws, at least one jaw of which moves reciprocally toward the other jaw and away from the other jaw in use, a supply device for supplying material to be crushed to the jaw crusher and a discharge device for discharging crushed material. The crushing device comprises a housing that encloses the jaw crusher, a ventilation device provided with air outlet openings that open into the crushing space, by means of which ventilation device air can be blown under pressure between the jaws of the jaw crusher device, and an exhaust device, which exhausts air mixed with fine material produced by the jaw crusher from the housing. The exhaust device is configured to convey the fine material mixed with the air to a collecting location. The invention further relates to a method for crushing material by means of such a crush device.

A mineral material processing plant includes a frame having two or more upper support surfaces and a jaw crusher including a crusher body having at least two bottom support surfaces at a distance from each other. The processing plant further includes at least one damper to be arranged in between the bottom and upper support surfaces which damper includes a first counter surface for the bottom support surface and a second counter surface for the upper support surface and an elastic material layer between the counter surfaces and preferably a slide joint between the first counter surface and the bottom or upper support surface. A method for damping a jaw crusher in a mineral material processing plant is also disclosed.

A pill crusher is provided, which comprises a base, a stopper, an U-shaped movable pressing plate, a connecting rod and a handle, wherein the stopper is mounted on the base; the U-shaped movable pressing plate is sleeved on the outside of the stopper and comprises a pressing plate on one side of the stopper and two side walls connected with the pressing plate and pivotedly connected to the stopper, so that the U-shaped movable pressing plate can rotate relative to the stopper and a V-shaped crushing chamber formed between the pressing plate and the stopper is capable of being closed by pressing and being open; the connecting rod is positioned on the other side of the stopper and has a first end pivotedly connected with the stopper and a second end; the handle has a first end pivotedly connected with the second end of the connecting rod through a third shaft pin and a pivoting portion pivotedly connected with the two side walls; as the handle is pressed down, the angle between the connecting rod and the handle increases and the space of the V-shaped crushing chamber decreases gradually; and as the handle is raised up, the angle between the connecting rod and the handle reduces and the space of the V-shaped crushing chamber increases gradually. The pill crusher provided by the present invention has the advantages of labor saving, high efficiency, quietness, convenient maintenance and cleaning and the like.

摘要:
The present invention provides an apparatus comprising a substrate and first and second disks. The disks are rotatably located over the substrate, each disk having an outer circumference with teeth thereon. The first disk is positioned to interleave one or more of its teeth with the teeth of the second disk. The substrate includes a channel with an exit port located near the teeth of one of the disks. Another apparatus comprises at least one disk rotatably located over a substrate and in a well of the substrate, the disk having an outer circumference with teeth thereon. The disk is positioned to provide a maximum distance of less than about 10 microns between each one the teeth and a nearest wall defining the well. The substrate includes a channel with an exit port located near the teeth of the disk.
摘要:
A crusher comprising at least a first crushing blade and a second crushing blade which are arranged to be rotary, one of the crushing blades being also arranged to move back and forth along a substantially harmonic linear path, and the rotating axes of the first crushing blade and the second crushing blade being parallel with the linear direction of movement of the second crushing blade. The second crushing blade is adjusted to move substantially harmonically back and forth along a linear path.

A crushing apparatus includes a substantially U-shaped spring member having a first beam portion having a first free end, a second beam portion having a second free end, and a fixed center portion. The first and second free ends are in opposed, spaced relation with each other. A first crushing mass is positioned on the first free end, and a second crushing mass is positioned on the second free end of the spring member. An exciter is configured to excite the first and second beam portions at about a common first modal frequency. When so excited, the first and second crushing masses reciprocally converge and diverge such that material positioned between the crushing masses is at least partially crushed therebetween.

The invention is a crusher having a fixed crusher member and a vertically reciprocating crusher member. Reciprocation of the crusher member is achieved by a pivoting arm located beneath the crusher member which is preferably driven by a toggle mechanism located to one side of the crusher.
摘要:
Rubber particles having textile and/or metallic inclusions are treated by first placing the particles on a support surface and then pressing the particles against the support surface in a direction transverse to the support surface with a surface of a press body exerting a pressure of in excess of 10 kg/cm.sup.2 without contacting the surfaces with each other. Both of the surfaces are nonsmooth. In accordance with the invention the support surface and the press body are relatively displaced in a direction generally parallel to the support surface to subject the particles to shear.
摘要:
Brittle material (1) is ground batchwise as a bed of particles by compression between non-yielding hard surfaces at a pressure of at least 50 MPa. In order to reduce the energy requirement and machine expenditure needed for fine, superfine and microfine comminution, the bed of particles is subjected to repeated stressing by pistons (4) in different directions and at least in part successively. The stressing preferably is accomplished by groups of two opposed pistons (4), which are offset at an angle with respect to each other and which are rendered active one after the other. The stressing is repeated in another plane of the grinding chamber. Wet grinding is carried out in a closed grinding chamber from which the liquid expelled from the voids between the particles being ground can drain through at least one aperture of narrow cross section.
