Abstract: The milling device comprises a milling roller running in a milling ring, wherein the diameter of the milling roller is at least equal to the inner radius of the milling ring. The milling roller is driven by a tangential force. By this arrangement it is guaranteed that the center of mass of the roller runs about the mill's central axis at a constant frequency that does not depend on the wear of the roller or the ring. Furthermore, the axis of rotation of the roller is not tilted during operation such that no torque is generated.

Abstract: A device for producing suspensions of finely divided matter includes a dispersion mill of the type with a slotted rotor and stator. The stator has chamfers on the leading edges to permit fluid flow from the rotor into the stator which is longer in duration, of greater volume, and along a path resulting in an impact angle of 90 degrees. The impact angle generates stagnation forces of a magnitude that results in cavitation when the fluid accelerates away from the impact zone. Subsequent discharges of fluid from rotor to stator slot creates increased ambient pressure around the vapor cavity accelerating cavity collapse and generating high pressures through accelerated collapse and through reentrant jet effects. Shock waves are transmitted locally which disintegrate particulates such as cells.

Abstract: A roll mill has a fixed roll journalled in stationary fixed bearings and a floating roll journalled in movable bearings enabling the floating roll to be pressed against the fixed roll under high pressure. An adjustable spacing arrangement is provided between the two bearings to enable a gap of selected width to be formed between the rolls. The spacing arrangement includes a pair of shaft-like distance members received and guided in associated bores of the fixed bearings for movement therealong. Free ends of the distance members extend outward of their bores and engage the opposing floating bearings to adjust the positions of the rolls as they wear so as to maintain the selected gap width. The free ends are retractable into the bores to allow the bearings to abut one another and thereby optimize the wear life of the rolls.

Abstract: A vertical roller mill which maintains a predetermined milling capacity for a long period of operation is disclosed. The outer portion of the grinding face of a milling roller is chamfered with respect to a tangent drawn at the point at which chamfering of the grinding surface of the milling roller begins and/or the outer portion of the surface of a table liner is chamfered with respect to a tangent drawn at the point at which chamfering of the surface of the table liner begins. Through this structure, a milled material is smoothly discharged to the outside of the milling table, and an otherwise possible overload to the vertical roller mill is prevented. Further, the wide and shallow abrasion pattern resulting from the use of this structure means the vertical roller mill can maintain a predetermined milling performance for a long period of operation.

Abstract: An improved cone crusher for crushing rock and the like has a welded metal hardfacing pattern made by welding beads of chromium carbide or similar hardfacing material to selected portions of its crushing surfaces. Tungsten carbide particles are introduced into the weld puddle as the beads are deposited. Predetermined spacing is maintained between adjacent beads to expose portions of the crushing surfaces. The beads can be deposited in recessed grooves in the crushing surfaces for increased lateral support. In the preferred embodiment, the beads are welded in a concentric circular pattern on the mantle and bowl liner of the cone crusher.

Its face (24) exposed to the grinding elements includes cavities (26) to allow the grinding elements to be embedded therein.

Abstract: Rows of finger blocks are mounted to a frame body of a rotary industrial shredder laterally parallel to respective ones of the counter-rotational pair of shafts so as to be moveable slightly, but meaningfully, during the shredding operation while maintaining tight clearance relationships between the fingers and cutters. In such a manner, waste material, particularly waste fibrous material such as waste carpet, may be stripped satisfactorily from the cutter and spacer discs carried by the shafts. Preferably, the finger blocks include unitary cutter and spacer fingers extending inwardly towards the shafts in respective opposed relationship to cutter and spacer discs carried thereby.

Abstract: A cryogenic vibratory mill designed to receive cooling fluid such as liquid nitrogen within a grinding chamber for grinding of feed material such as crumb rubber from vehicle tires for cryogenic comminution within a grinding chamber. Cooling within the grinding chamber is achieved by passing cooling fluid such as liquid nitrogen therethrough wherein most of the cooling fluid passes through longitudinal channels formed longitudinally in the cylindrically shaped grinding rods. The operating temperature is normally less than -120 degrees Fahrenheit. A vibrating drive is operative to vibrate the housing and the grinding rods therein to achieve comminution of the feed stock rubber passing therethrough. With this design most of the cooling is achieved by passing of the cooling fluid through the channels defined in the grinding rods with only a minimum amount of cooling achieved by cooling fluid passing through the grinding chamber between the rods.

Abstract: The method of assembly of a mop head which includes a polymer carrier in the form of a channel with in-turned lips or barbs on opposed flanges that retain compressed mop material without the need for glue or the like. The method includes compressing a block of mop material between two surfaces to reduce its thickness and to stiffen it, and then driving the compressed mop material into the channel, whereupon expansion of the mop material engages the lips or barbs. The molded polymer carrier channel is relatively rigid and can have reinforcements to resist resilient opening of the channel. The extent of compression of the mop material is substantial, for example, by a factor of four or five during compression, and another factor of two when passing through the nip between the lips.

Abstract: The invention is directed to a new method for the production of a starch raw material for subsequently obtaining pure starch from wheat, rye, corn or barley. Fractions of starch which is damaged as little as possible are produced by means of roller grinding and sifting devices. The material is ground repeatedly and sifted with the system of advanced milling, wherein it is suggested in particular to guide the material two to five times via double-grinding stages without sifting between the double grindings. Sifting is effected subsequent to the double grinding. The invention also concerns a starch milling system which comprises two to five double-grinding passes with two grinding-roll pairs which are connected one after the other and are preferably constructed as an eight-roll mill.
