Abstract: A grinding machine includes first feed screw, first head, first center pin, first knife assembly, bushing and first orifice plate. Second feed screw is coupled to first center pin and rotates within second head. Second feed screw is positioned against the bushing such that the bushing acts as a thrust bearing. Second center pin is coupled to second feed screw and is configured to rotate a second knife assembly. Second orifice plate is arranged on second center pin. Second mounting ring can be linearly adjusted relative to second head to axially position second orifice plate between a stop shoulder of second head and a lip of second mounting ring. Second feed screw may include a plurality of flights arranged in a split flight configuration including one or more ingress end flights and one or more egress end flights.

Abstract: A system for comminuting solid waste material including a shredding device disposed within the casing and comprising parallel first and second shredding stacks that include first and second parallel shafts rotatably mounted between an upper shredding device housing and a lower shredding device housing and a rotating screening drum disposed within the casing and mounted between an upper screening drum housing and a lower screening drum housing, the rotating screening drum configured to permit fluid to pass therethrough while capturing solids on an outer surface for delivery to shredding device, an upstream portion of the rotating screening drum disposed upstream of an upstream portion of the shredding device. The upper shredding device housing and the lower screening device housing are separate members from the upper screening drum housing and the lower screening drum housing to permit interchangeability of different sizes of these components to meet system needs.

Abstract: A mincing machine for mincing a product, in particular for mincing meat, includes at least one stationary hole plate and at least one rotating hole plate which interact to mince the product. The mincing machine has a rotating cutter head mounted on a shaft wherein said cutter head is arranged upstream of the interacting hole plates in the conveying direction of the product to be minced in order to interact with a stationary hole plate to mince the product.

Abstract: A device for separating the hard components for a grinder used in the field of the food industry, and more particularly of the mincing of meat, downstream of one or several cutting assemblies, includes a grid for stopping hard components which is associated with a separating cutter of for draining hard components towards the center, in order to cause them to pass into a collecting tube which is screwed into a supporting grid or spider according to an adjustable depth. The collecting tube includes, an axial recess capable of receiving the end of a driving shaft of the cutters of the grinder, so that the latter can be held transversely and rotate in it and, peripherally with respect to the axial recess, at least one channel allowing the transit of hard components.
