摘要:
A mineral breaker is described having a breaker unit (1) with at least one rotary drive shaft (15), a rotary electric motor (13), and a drive gear box (17). The breaker unit drive shaft is coupled for rotation to an output shaft of the drive gear box, the rotary electric motor is coupled to rotatably drive an input shaft of the main drive gear box. The rotary electric motor is a switched reluctance motor.

A gyratory crusher outer crushing shell (200) and a crushing shell assembly. The crushing shell comprises a radially inward facing crushing surface (209) and a radially outward facing mount surface (225) provided with radially outward projecting contact regions (219,220) to contact the topshell (100) or an intermediate spacer ring (203). A ledge (213) or groove (1000) having an abutment face (300)is positioned at or axially above the upper contact region (219) to positionally support a sealing ring (214) for positioning between the crushing shell and the topshell or intermediate spacer ring.

The present invention discloses a composite milling cone for compression crushers, said milling cone comprising a ferrous alloy at least partially reinforced with titanium carbide according to a defined geometry, in which said reinforced portion comprises an alternating macro-microstructure of millimetric areas concentrated with micrometric globular particles of titanium carbide separated by millimetric areas (2) essentially free of micrometric globular particles of titanium carbide, said areas concentrated with micrometric globular particles of titanium carbide forming a microstructure in which the micrometric interstices between said globular particles are also filled by said ferrous alloy.
摘要:
A cone crusher mantle armor for ore comminution, comprising: a. grooves laid out in the form of spires or helixes over the mantle, where such grooves are integral to said mantle thus forming the mantle armor, and b. such grooves and said mantle are manufactured in a single casting.
摘要:
A shell (4, 5) for use in a gyratory crusher has a support surface (18), which is intended to abut against a shell-carrying member (3), and a first crushing surface (20), which is intended to be brought into contact with a material supplied at the upper portion of the crusher, and to crush said material against a corresponding second crushing surface (24) on a second shell (5) complementary with the shell (4). Over at least 50% of the vertical height (H) thereof, from an outlet (30) and upward along the first crushing surface (20) the first crushing surface (20) has been machined to a run-out tolerance, which on each level along the machined part of the vertical height (H) of the first crushing surface (20) is maximum one thousandth of the largest diameter of the crushing surface, however maximum 0,5 mm. In a method of producing a shell, the shell is manufacture with a machining allowance and is then machined to desired run-out tolerance
摘要:
Die Erfindung betrifft einen Brecher, der zur Erzeugung von halbleiter- oder solartauglichem Siliciumfeinbruch aus halbleiter- oder solartauglichem Siliciumbruch geeignet ist, umfassend mehrere Brechwerkzeuge, wobei die Brechwerkzeuge eine Oberfläche aus einem harten, verschleißfesten Material besitzen, dadurch gekennzeichnet, dass der Brecher ein Zerkleinerungsverhältnis von 1,5 bis 3 aufweist.
摘要:
A cone crusher comprising a mantle fixed to and rotatable with a head shaft about which an eccentric weight or unbalanced mass is relatively rotatable, the head shaft and eccentric being commonly driven by a friction drive which permits a degree of angular movement of the rotational axis of the head shaft relative to the rotational axis of the friction drive. In accordance with the invention means is provided for supplying a lubricating fluid under pressure from the friction drive to the interior of the head shaft, the head shaft having at least one radial bore which communicates its interior with the peripheral surface of the head shaft at a position where the shaft is surrounded by the eccentric.
