Abstract: A cleaning process and apparatus for cleaning small diameter clogged holes or passages fashioned as deep through-holes or small diameter through-holes of varying sizes. The holes may be provided in dies for enabling a pressing of materials for manufacturing of pellets such as feed stuff pellets. The cleaning is effected by directing at least one water jet having a diameter less than one-half of a smallest diameter of the hole or passage to be cleaned. The cleaning medium is supplied possibly at supersonic speed. It is also possible to clean radially oriented holes or passages in the die by ejecting the cleaning medium from nozzles of the apparatus.

Abstract: A pellet mill (1) is provided with a control unit with the help of which a desired value of press roll slippage, e.g. zero or a pre-selectable peak value can be maintained. For this purpose, the pellet mill (1) comprises a first measuring unit (27, 28) for measuring the circumferential speed of the perforated die (8) as well as a second measuring unit (23, 24) for measuring the circumferential speed of the press rolls (11, 12). In a comparator (30, 31), the two circumferential speeds are compared and on exceeding a pre-selectable peak value for the difference of the two measured values, a slip signal is created by means of which the mill drive, and/or the supply of basic material to be formed is influenced in such a manner that the slippage will be prevented.

Abstract: A feed device for low-density particulate materials is disclosed for a pelletizing machine. A fin (25) forming a helicoidal spiral on the outer surface of a tubular dome (24) connected to a drive shaft (23) carries the material to one end of the dome, where the volume of air contained in the bulk material is diverted toward the interior of the dome (24) without causing a flow contrary to the displacement of the material, thus eliminating the problem of flow interruptions caused by air entrapment.

Abstract: A granulating apparatus includes a hollow roll equipped on its internal circumference with axially extending toothed ledges and a co-rotating contact pressure roll, equipped with corresponding axial toothed ledges on its outer circumference, and engaging in the hollow roll in the lower area of the latter. The hollow roll is provided with axially extending rows of holes between its toothed ledges. The toothed ledges of the hollow roll and pressure roll intermesh to form a tapering nip zone therebetween. The material to be granulated is fed into the hollow roll and into the nip zone. By means of the cooperation of the toothed ledges, the material is pressed out forcibly and volumetrically in the downward direction. The drops being formed fall onto a cooling conveyor and are allowed to solidify thereon. The mass is extruded forcibly and with a defined volume. By virtue of the cooperation of rotating parts, high production rates are possible.

Abstract: The rear end of a rotary drying drum (1) is provided with a peripheral channel (10) in which dried material to be briquetted, such as green crops, wood flakes or peat, is accumulated and carried along. The bottom of the channel (10) is formed by the inner periphery of a ring of dies (18), in which the formation of briquettes takes place by means of a pressure roller (17) operating in the channel (10) and compressing the material against the frictional resistance in the dies.The material has previously been precompressed by an endless band (19) likewise operating in the channel (10), which band preferably runs at the same peripheral speed as the pressure roller (17) and the inner side of the die ring (18).

Abstract: An improved pellet mill die is disclosed which has improved production efficiency without a corresponding loss in pellet quality or durability. The die comprises a compression side, a discharge side, and a plurality of die holes extending through the die. The die holes have a countersink on the compression side, and preferably at least a portion of die holes have a relief section to thereby define a working section of the die hole where the pellet is formed, and an effective thickness for the die holes which is preferably less than the distance between the compression and discharge side of the die. The die has a ratio of effective thickness to countersink diameter of at least about 1.8 to 1 wherein the countersink diameter is at least about 137% and preferably between about 137-159% of the working section diameter.

Abstract: A process and apparatus for pelletizing tree bark and other botanical material for use as an industrial fuel. A dryer burning fines from the final product is used to heat bark or other botanical material which is typically a waste product from lumbering or agricultural production. Once dried, the material is finely ground, preheated and forced through a pelletizing mill to create a pelletized product having a diameter of approximately 0.635 cm. The pellets are then cooled and leave the process. Several pelletizing mills are disclosed which are situated to trap the dried material against at least one die such that there will be a continuous, positive feed of material into the die. The resulting product may be substituted for coal as a heating source.

Abstract: Fodder is converted into shape-retaining blocks or cakes by an apparatus which collects fodder off the ground and subjects it to a preliminary compacting action, thereupon to a twisting action which results in the formation of ropes of convoluted material, and to final compacting action resulting in conversion of ropes into blocks or cakes of firmly compacted material. The twisting and final compacting actions can be carried out sequentially or simultaneously.
