Abstract:
A crushing apparatus comprising first and second crushing jaws with each of the crushing jaws having a crushing surface. The crushing surfaces are arranged to define an acute angle no larger than about 45 degrees and to at least partially define a crushing cavity for receiving material to be crushed. The crushing jaws are relatively moved along a path generally parallel to the crushing surface of the first jaw so that the spacing between the crushing surfaces does not vary with the relative movement of the jaws. The relative movement between the jaws can be linear or rotational.
Abstract:
A grinding apparatus intended for domestic use in making nut butter from nuts such as peanuts can be constructed so as to utilize a housing containing a motor. The motor shaft is used to support a lower assembly and to drive a lower grinding disk forming a part of this assembly. An upper assembly is movably mounted on the lower assembly in such a manner that the relative position of an upper grinding disk relative to the lower grinding disk can be adjusted or varied in order to obtain what may be referred to as a "smoothly ground" product or what may be referred to as a "chunky ground" product consisting of particles ground to various different sizes. An actuator is provided for moving the upper assembly so as to obtain either of these types of products. A hopper structure is used to convey nuts or other material to be ground through the upper assembly to a space between the two grinding disks. This hopper and the upper assembly are constructed so as to accomodate the relative movement of the upper assembly without the possibility of the material to be ground being conveyed by the hopper to other than the interior of the upper assembly.
Abstract:
An apparatus (100) has a batch container (110) having one or more openings (120) for the introduction of the substances to be processed, one or more openings (130) for the discharge of the processed substances, and a process chamber (140) having a rotor (150) and a stator (160), the rotor (150) mounted rotatably about a rotational axis (155) with respect to the stator (160) for the purpose of processing substances introduced into the process chamber (140). The stator (160) has a working surface (161) which is inclined at an angle W1 in relation to the rotational axis (155) of the rotor (150) and the rotor (150) has a working surface (151) which is inclined at an angle W2>W1 in relation to the rotational axis (155) of the rotor (150), such that the working surfaces (161, 151) of stator (160) and rotor (150) are disposed at an acute angle relative to each other. The process chamber (140), in which the introduced substances are dispersed, comminuted and homogenized, is formed between the rotor (150) and the stator (160) and is of hollow-conical cross section.
Abstract:
A grinding apparatus having two mulling plates disposed horizontally in superposed relation is provided. The lower mulling plate is connected to suitable drive means for rotating the plate (the direction of rotation is reversed intermittently). The upper mulling plate is eccentrically connected to a support structure and is provided with a guide pin connected at one end to the plate and which extends at the other end through a slot in the support structure. In operation, the lower mulling plate upon rotation effects movement of the upper mulling plate about its eccentric axes, but the extent of travel of the upper mulling plate is controlled or limited by the guide pin which contacts one end or the other of the slot in the support member. The apparatus is useful for grinding pigment and paint.
Abstract:
A plate mill for crushing gravel, pebbles or the like, of the type comprising two rotating discs or plates is provided with means for adjusting the separation of the plates while they are in motion so that the required adjustment in relation to the size of the output particles from the mill can be achieved readily. A first one of the plates is carried by a rotating cylinder, and is spaced from the cylinder by spacers; a second plate is carried between the end of the cylinder and the first plate at the end of a shaft mounted by means of a ball and socket coupling in a piston which is axially movable within the rotating cylinder. Oil passageways leading to the interior of the cylinder direct pressure fluid, preferably lubricating oil, to the underside of the piston so that the second plate can be urged thereby toward the first plate.
Abstract:
A rotary groundwood mill comprising two discs arranged to face each other and rotated in their major planes about eccentrically located axes. The discs are rotated at exactly the same speeds and in the same rotational direction. The mill structure is such that a piece of wood entrapped between the discs will be subjected to epicyclic abrasion.
Abstract:
An apparatus for the production of pressings from bulk material in powder, piece, swarf or fiber form, in which the bulk material is fed to rotating working elements, wherein two similar disc dies (1, 2) having conical surfaces (15, 16) in the region of a ring are rotatingly mounted by means of shafts (10, 11) opposite to one another in similarly mutually opposite machine bodies (3, 4) in such manner that the axes of the shafts (10, 11) intersect at an obtuse angle, preferably greater than 150*, and the disc dies (1, 2) come into contact with one another on a common generatrix of their conical surfaces (15, 16) and roll on one another on rotation in the same direction, while a feed device (13) and a discharge device (14) are associated with the disc dies (1, 2) and the machine bodies (3, 4) are connected with one another by elements which produce a force-operated engagement.
