Abstract:
A conveyor for conveying mineral material vertically comprising a conveyor frame (250); at least two conveyor main rolls (110) or at least two pairs of conveyor main pulleys (413), a plurality of conveyor guide rolls (120) or conveyor guide pulleys (403,423) and a first (101,401) and a second (201,411) endless material transport means being arranged to be moved on the conveyor main rolls and on the conveyor guide rolls. The main rolls (110) or pairs of main pulleys (413) are arranged on top of each other and the guide rolls (120) or guide pulleys (403,423) are arranged outside each conveyor main roll or main pulley at a circumference of a circle. The endless material transport means are arranged to alternate between being moved in turn on either a main roll (110) or a pair of main pulleys (413) or on a group of guide rolls (120) or guide pulleys (403,423).The endless material transport means are arranged to be moved at such a speed that any material being conveyed stays in contact with the surface of either the first or the second endless material transport means when being moved on a the conveyor guide rolls (120) or guide pulleys (403,423).
Abstract:
A crusher comprising at least a first crushing blade (1) and a second crushing blade (2) 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 (X) of the first crushing blade (1) and the second crushing blade (2) being parallel with the linear direction of movement of the second crushing blade (2). The second crushing blade (2) is adjusted to move substantially harmonically back and forth along a linear path.
Abstract:
A jaw crusher (100) comprising a body (2) to which are arranged a fixed jaw (3) and a pitman (4) which is movable against the movable jaw for forming a crushing chamber (6) which is open at the top; and the pitman is bearing-mounted to an eccentric shaft (7) which is bearing-mounted rotatably to the body forming so a first pivot point (8) and the pitman is bearing-mounted to the eccentric shaft at an eccentric point of the eccentric shaft forming so a second pivot point (9); and the pitman is supported to the body by a pivot bar (11) which is pivoted at a first end of the pivot bar to the pitman forming so a third pivot point (12) and at a second end of the pivot bar to the body forming so a fourth pivot point (13); and for directing a crushing stroke to the material to be crushed in a direction which is substantially perpendicular to the bisector (6') of the crushing chamber (6): the at least one pivot bar (11) which is pivoted to the pitman is arranged such that a plane passing through the third pivot point (12) and the fourth pivot point (13) is arranged substantially parallel (± 20°) with the bisector of the crushing chamber. A crushing plant. A method for crushing mineral material in a jaw crusher (100) or a crushing plant (200).
Abstract:
An adjusting apparatus (10) of a feed opening (121) of a crushing chamber (122) of a crusher (120) comprises one or more adjusting parts (5, 6, 7, 8; 901, 902; 911, 912, 913, 914) to be arranged in connection with the feed opening, which one or more adjusting parts is/are movable during crushing for adjusting a flow area (A) of material which is to be crushed and is flowing through the feed opening (121) to the crushing chamber (122), and front edges (5.1, 6.1, 7.1, 8.1) of the adjusting parts (5, 6, 7, 8; 901, 902; 911, 912, 913, 914) are forming a unitary flow opening (11; 907), the flow area (A) of which flow opening is adjustable by moving one or more adjusting parts. An adjusting system comprises an adjusting apparatus (10) for a feed opening (121) of a crushing chamber (122) of a crusher (120). A pressing crusher (120) suitable for mineral material crushing. A crushing plant (100). A method for adjusting a pressing crusher (120) or a crushing plant (100) suitable for mineral material crushing. A method for avoiding a start peak of a crusher. A method for limiting power intake and/or crushing pressure of a crusher.
Abstract:
A jaw crusher, a mineral material processing plant and a method for processing mineral material. The jaw crusher (100) comprises a fixed jaw and a movable jaw for forming a crushing chamber (3) therebetween which is open at the top, the fixed jaw comprising a first wear part (1 ) mounted thereto and the movable jaw comprising a pitman (4) and a second wear part (2) mounted thereto; wherein the pitman (4) is rotatably mounted to a first eccentric shaft (8). The pitman (4) is further rotatably mounted to second eccentric shaft 9 configured to guide the stroke of the movable jaw to create a movement pattern with a substantially linear crushing stroke, wherein the eccentricity of the second eccentric shaft (9) is larger than that of the first eccentric shaft.
