A crushing control apparatus for a shearing crusher, which properly controls the crusher in accordance with kinds of objects to be crushed and is capable of reliably preventing stop of operation due to excessive load, clogging and the like, is provided. For this purpose, the crushing control apparatus includes a mode selecting switch (59) for selecting a mode according to each kind of the objects to be crushed, a ROM (33a) for storing a control condition of the rotary shafts (11, 11), which conforms to the mode for each of the mode, and a controller (33), which reads out the control condition corresponding to a selected mode from the ROM, when the predetermined mode is selected by the mode selecting switch, and controls the rotary shafts to be in the control condition which is read out.
A crusher for crushing cooked wood chips or the like finely. A raw material to be crushed such as the cooked wood chips is delivered into a housing and clamped between stationary blades attached to a stationary plate housed in the upper end of the housing and rotary blades attached to a rotary plate rotating in the housing, so that it is finely crushed by the stationary blades and the rotary blades by making use of the planer principle. The crushed products are carried in the air flow, which is generated around a guide vane disc, which rotates in a through hole formed in a substantially central portion of the stationary plate, and forcibly delivered from an exit in the housing side wall front portion inclined forward, to the outside of the housing.
A mobile jaw crusher assembly for crushing objects is provided. The assembly includes a frame and a first crushing member that is configured to be moved and at least partially rotated by a vehicle. The first crushing member is configured to be attached to the vehicle. A second crushing member is also present and faces the first crushing member. The first and second crushing members define a crushing chamber that is used for crushing objects. The second crushing member is configured to be moved and at least partially rotated by the vehicle.
Conical crusher anti-spin assembly
A cone crusher includes a frame, a shaft supported by the frame, and a head disposed on the shaft. An eccentric mechanism is coupled to the head. A one-way clutch is coupled to the shaft, and a friction torque limiting clutch is disposed within the head and coupled between the head and the one-way clutch.
The invention relates to a device for loading a fragmenting machine, such as a hammer crusher, including a front and rear upper drive roller which are equipped, independently of each other, with a drive mechanism and arranged above the feed plane of a feed chute. The drive rollers are mounted on a displaceable and pressure exerting system of levers, such that a continuous, pre-pressed and controlled feed of recyclable material for fragmenting is guaranteed.
A hammer crusher has a rotor disk centered on and rotatable about an axis, having a predetermined outside diameter, and formed with five angularly equispaced and radially outwardly open pockets. Respective support bolts in the cavities define on rotation of the disk an orbit of generally the same diameter as the predetermined outside disk diameter. Respective hammers pivoted on the bolts project radially from the cavities on rotation of the disk. A pentagonal-section shaft carries the disk and has facets directed radially outwardly at the respective bolts.
A variable throw eccentric cone crusher. The cone crusher comprises a frame, a crusher head supported on the frame for gyration about a first axis, a bowl supported on the frame in spaced relation to the crusher head, and a mechanism on the frame for varying the eccentricity of the gyration of the crusher head. An eccentric member engages the crusher head and is eccentrically pivotable about a second axis radially offset from the first axis. The eccentric member is adjustable to vary the eccentricity of the gyration of the crusher head.
Adapter for rock crusherA jaw crusher for crushing rocks combines a hydraulic adjustment of the bite with an air spring tensioning arrangement which maintains a desired tensile force even with variation of the bite. The air spring arrangement is reliable in the dirty environment and also has long life. The use of several air springs in combination with a pressure sensing arrangement adds a safety factor. The more consistent tensioning force allows adjustment of both the tensioning arrangement and the bite of the rock crusher during operation thereof.
A cone crusher alternatively operable with either a first bowl liner or a second bowl liner, the crusher including a frame, a crusher head, a bowl supported by the frame, the bowl including a bowl liner mounting surface, a locking mechanism on the bowl and the bowl liner for alternatively fixing the first bowl liner and the second bowl liner to the bowl, the locking mechanism including at least one locking assembly including a wedge member, a first link, a lock pocket defined by the bowl and being adapted to receive the first link, a lock mount defined by the bowl and being adapted to receive the first link, the lock pocket and the lock mount being respectively located relative to the bowl liner mounting surface such that the locking assembly is engagable with the locking flange of the first bowl liner when received by the lock pocket and such that the locking assembly is engagable with the locking flange of the second bowl liner when received by the lock mount.
A gyratory crusher having a frame (1) and in the frame an eccentric shaft (3) rotatable around a vertical shaft in the frame, with a vertical inclined hole in it. A main shaft (4) is supported by bearings in the hold of the eccentric shaft, a supporting cone (5) being attached to the upper end of said main shaft (4). Around the main shaft, below the supporting cone (5) there is a sealing cover (10) covering the eccentric shaft. The upper edge (12) of the sealing cover (10) is sealed against the main shaft (4) by means of a sealing member (13), the outer edge of which has been fitted in an annular groove (17) on the inner edge (12) of the sealing cover (10). The face-to-face arranged upper and lower surfaces so the part (13") of the sealing member (13) in the groove and the groove (17) of the sealing cover (10) are inclined so that their outer edges are higher up than their inner edges.
