Abstract: A coffee grinder grinds a predetermined amount of roasted coffee beans based upon the weight of the beans. The beans fall from a hopper into a grinding head which grinds the beans in a two-stage process. The first stage includes a cracking cutter, consisting of a cone cutter and a reel cutter, which reduces the beans to an initial particle size of approximately 1/16 of an inch in cross-section. The particles are then progressed by the grinding head, for the second stage of fine grinding, to an adjustable micro grinder consisting of two opposing rings having micro teeth on their inwardly facing surfaces. The cutters and grinder rings are mounted on thermally conductive metal hubs and a fan draws air around and behind the cutting teeth to cool them and avoid heating the coffee particles during the grinding process.
Abstract: A crushing apparatus for crushing synthetic resin molded products as wastes into the form of pellets. This crushing apparatus comprises a housing formed at top with a hopper into which pieces of molded products are discharged and at bottom with a dropping opening through which finely crushed material drop, and a driving shaft rotatably mounted on the middle of said housing. On the driving shaft are mounted rotating blade for rough crushing for roughly crushing the pieces of molded products and rotating blades for fine crushing for finely crushing the same, said both rotating blades being coaxially mounted. The lower portion of the rotating blades for rough crushing is covered with a cover member so that roughly crushed pieces may be repeatedly crushed without dropping into the dropping opening. If the pieces of molded products charged through the hopper have their size caught by the rotating blades for fine crushing, they are crushed into the form of pellets by the rotating blades for fine crushing.

The grinding space includes an inner grinding zone and two outer grinding zones which diverge at an angle to the radial plane of the inner zone. The inner grinding zone is defined between the two facially-opposed rotating discs in a plane substantially perpendicular to the axis of rotation, and the outer grinding zones are defined between portions of the two rotating discs which extend at an angle to the radial plane of the inner zone and correspondingly inclined facing surfaces of a stationary element such as a stator ring encasing the two rotating discs.
Abstract: A pressurized roller-colloid mill in which the conventional rotor and stator of a colloid mill are preceded by one or more adjustable-thrust roller bearing assemblies disposed in a series relationship. A product to be refined in the form of a slurry is pumped into the feeding port of the mill to pass between the rollers and the inner and outer raceways of one or more roller bearing assemblies, then to the gap between conventional rotor and stator elements of a colloid mill. The multiple rollers and their cooperating raceways constitute working surface areas far in excess of conventional colloid mill rotors and stators. Gang mounting of the rotor of the mill and the inner raceways of the roller bearing assemblies upon a common axially movable shaft permits gap adjustment for the enhancement of milling action. A relief valve at the outlet of the mill cooperates with the adjustable gap to provide an output of product of any desired particle size down to the low micron range.
Abstract: A vacuum blower-type mobile unit for shredding leaves and other garden debris. The unit comprises a pair of coaxially disposed rotors operated at respectively different speeds, the blades of the two rotors being separated by a minimum practical axial clearance to provide shredding action. Shredding is further enhanced by stationary radial blades fixed to the casing adjacent the input to the slow speed rotor, and a circular plate formed to include a large number of exit guide vanes including fixed blades disposed adjacent the output from the high speed rotor. The speed differential between the rotors and the shapes of the blades cooperate to create between them a high velocity axial stream of air and debris which moves smoothly through the machine, depositing the product in comminuted form in a bag or other container.
Abstract: Crude pulp stock is recovered from municipal waste by selectively pulverizing garbage (food waste) in the waste; removing the pulverized garbage; thence, moistening the rest of the waste so as to selectively weaken the materials, such as waste paper, usable as crude pulp stock; and taking out the pulverized crude pulp stock.

Abstract: A shaft is rotatably supported on both the ends of the housing. The housing has an inlet for charging discarded glass articles and an outlet for discharging glass fragments. Crushing bars are mounted on the shaft and arranged from near the inlet toward the neighborhood of outlet of the housing. The glass articles charged through the inlet into the housing are kicked by the crushing bars toward the inner surface of the housing and broken into fragments while being rebounded on the inner surface of the housing. The glass fragments dropped down onto the bottom of the housing are agitated, by poking bars mounted on the shaft in the neighborhood of the outlet, while being subjected to impact forces, to permit them to be reduced to substantially rounded gem-like granules.
