Abstract: A moving point involved in a movable teeth plate of an eccentric jaw crusher rotates on a closed loop, being called hysteresis curve in the specification. An angle between a major axis of the curve and the surface of a fixed teeth plate is a significant factor for crushing. The inventor found the fact that the alternation of the angle enables crushing ability to be rich. The angle is incontinuously varied. One of the positions at which a toggle plate is rotatably supported is selected. A larger angle is suitable for crushing harder materials, concrete for example, a small angle being suitable for soft materials, asphalt, for example. One self moving crusher can crush harder and soft materials at the same field where buildings are destroyed, or roads are repaired.

Abstract: The objective of this invention is to provide a method to adjust the position of a jaw crusher toggle block, and a device used for said method; wherein the said device can adjust the cavity width over a wide range, and can be applied to a wide range of jaw crushers, including large models, without itself having to be enlarged.

Abstract: A swing type crusher capable of efficiently breaking a non-rigid object into pieces of small particle size. A jaw crusher breaks a lump of asphalt cast into a V-shaped crushing space (V) which is defined between a fixed tooth plate (26) and a movable tooth plate (25), and which periodically changes its volumetric capacity. A toggle plate (12) is interposed between a body (1) and the movable tooth plate (25) to swingably support the movable tooth plate (25). A support member (9) which swingably supports the body-side end portion of the toggle plate (12) is vertically movably secured to the body (1). By vertically moving the support member (9), the spacing between the fixed tooth plate (26) and the movable tooth plate (25) is narrowed (widened), and at the same time, the stroke of the movable tooth plate (25) is reduced, thereby efficiently breaking a non-rigid object, e.g. waste asphalt, into small pieces, and reusing them immediately.

Abstract: This invention relates to improvements and modifications to a rock crusher. The rock crusher has at least two jaws the jaws being driven at different ends to each other. The non-driven end of at least one jaw is sufficiently free to allow vertical movement of that jaw with respect to the other jaw. This vertical movement imparts a grinding action in addition to the crushing action of the rock crusher. This removes the problems which can occur with wadding and can produce a very fine ground rock.

Abstract: A jaw crusher designed to break a non-rigid object, e.g., asphalt, into pieces of desired size without causing the object to be undesirably mashed by changing the motion of a movable tooth plate relative to a fixed tooth plate. The jaw crusher includes a fixed tooth plate (16), a swing jaw (8), a movable tooth plate (15), and a toggle plate (10). Motion of a lower end portion of the movable tooth plate (15) which is on an approximately circular locus satisfies the conditions that the relative angle between a straight line connecting the lower and upper end points of the approximately circular locus and the fixed tooth plate (16) is not smaller than 20.degree., and that the distance between the lower and upper end points is not shorter than 50 mm.

Abstract: A crushing apparatus has an hydraulic cylinder for actuating a toggle mechanism connected to a moveable jaw. The apparatus may have a main frame with an opening near the top of the frame for admitting material to be crushed. There is a first jaw connected to the frame on one side of the opening by a first pivotal connection near the top of the jaw. A first toggle mechanism is operatively associated with the first jaw. There may also be a second jaw connected to the frame on a side of the opening opposite the first jaw by a second pivotal connection near the bottom of the second jaw. A second toggle mechanism is operatively associated with the bottom mounted jaw. The crushing apparatus may have a toggle mount which is movable towards or away from the associated jaw.

Abstract: A crusher, for example for rock or the like, has crushing jaws which are driven to swing towards and away from each other and are pivoted to a frame adjacent the ends of the jaws, so that most of the jaw movement is in a horizontal direction and is therefore a substantially balanced assembly.

Abstract: An apparatus for shredding waste material includes first and second cooperating shredding rotors rotatably mounted adjacent to one another in a shredding chamber. Each rotor includes a series of axially spaced toothed ripper blades removably mounted on a shaft and positioned so that the blades of one rotor interleave with the blades of the other rotor. The blades are arranged in a stacked assembly which may be removed as a unit for repair or replacement without removing the rotor shaft. A crank drive arrangement develops relative rotational oscillatory bi-directional motion between the rotors to shred material fed therebetween. The rotors are oscillated out of phase with one another so that their teeth are continuously moving at different relative angular velocities with respect to one another.
