A wood chipper which includes a chamber having a flywheel and which includes a wood in-feed system. The in-feed system includes a bin inclined for gravity-feeding wood product to the chamber and a cylindrical anvil disposed between an outlet of the bin and the flywheel. The flywheel includes a plurality of plates laminated together with fasteners. First and second ones of the plates have aligned first and second openings respectively for passage of chips. The second opening has a tab which extends from an edge thereof partially into the first opening. A knife is attached to the tab and supports a blade outwardly of the first plate and thus outwardly of the flywheel. A system is provided for providing water mist onto wood product only as it is being fed down the in-feed bin.

The present invention relates to a grinding cosmetic container, and grinds solid cosmetic contents by means of a grinding member so as to enable application of same as powdered cosmetic contents, thereby allowing cosmetic contents to be uniformly stuck to a puff and, simultaneously, allowing the cosmetic contents to be refilled and used.

A wood chipper, a flywheel therefor, and a process of making the flywheel. A plurality of plates are laser cut to each have a thickness up to about ⅜ inch, including laser cutting a plurality of apertures in each of the plates and laser cutting a central opening in each of the plates for receiving a shaft for effecting rotation of the flywheel. The plurality of plates are laminated together by inserting fasteners in corresponding ones of the apertures in the plates. At least one knife is attached to the laminated plates for cutting wood material to form chips of the wood material as the flywheel is rotated.

A blending system that includes a base that is selectively and operatively engaged with a container is shown and described herein. The base may include a near field communications chip that may communicate with a near field communications chip of a cutting disc. The cutting disc identifies a type of the cutting disc, a position of a chute of a lid or both.

A disc chipper for crushing lumpy feed material. The disc chipper has a crushing rotor driven by a drive unit, rotating about an axle, including a rotor shaft and a chipping disc connected in a rotationally fixed manner with the rotor shaft. The chipping disc has chipping knives, which are transversely aligned in the disc plane to the rotational direction and which cooperate with stationary counter knives for the comminution of the feed material. In order to ensure a secure and accurate fastening of the chipping disc on the rotor shaft and to thereby conduct the driving force from the rotor shaft to the chipping disc without damage, the rotor shaft in the region of the bearing seat for the chipping disc has a polygonal cross section and the chipping disc has a centric through-hole form-locking thereto.

A system for recycling pocketed metal coil mattresses includes a primary shredding station that implements a primary shredder element having a housing with opposing shafts mounted to extend along sidewalls of the housing. Each shaft includes a plurality of opposing shredding knives configured to bypass each other for shredding materials in the housing into metal and fabric pieces. The knives each have a thickness in the range of 17-50 mm with the knives of each respective opposing shaft being spaced apart from each other along the respective shaft in the range of 17-50 mm. The primary shredder element is free of stationary elements in the spaces between the shredding knives at the sidewalls. A motion separation station utilizing motion of the fabric pieces and the metal pieces for separating the pieces follows the primary shredder station. An air separation station provides an airflow to separate fabric pieces from the metal pieces. A secondary shredding station for further shredding the material is used to further shred and separate materials. A magnetic separation station further separates the metal and fabric pieces.

A disc chipper for crushing lumpy feed material. The disc chipper has a crushing rotor driven by a drive unit, rotating about an axle, including a rotor shaft and a chipping disc connected in a rotationally fixed manner with the rotor shaft. The chipper disc includes chipping knives, which are transversely aligned in the disc plane to the rotational direction and which cooperate with stationary counter knives for the comminution of the feed material. The drive unit include a primary drive and a secondary drive, which drive the crushing rotor via a transmission, wherein the primary drive is in active operative connection with the crushing rotor during the crushing operation, and the secondary drive during the acceleration process or when readjusting the crushing rotor for purposes of maintenance and repair.

A blending system that includes a base that is selectively and operatively engaged with a container is shown and described herein. The base may include a near field communications chip that may communicate with a near field communications chip of a cutting disc. The cutting disc identifies a type of the cutting disc, a position of a chute of a lid or both.

Embodiments are disclosed of an apparatus with a first planar cutter including a center and a plurality of through-holes and a second planar cutter positioned on the first planar cutter and including a center and a plurality of through-holes. An axle passes through the center of the first planar cutter and is coupled to the center of the second planar cutter, so that rotation of the axle produces rotation of the second planar cutter relative to the first planar cutter. At least the surface of one of the first planar cutter and the second planar cutter is made of a friction-reducing material.

A wood chipper, a flywheel therefor, and a process of making the flywheel. A plurality of plates are laser cut to each have a thickness up to about inch, including laser cutting a plurality of apertures in each of the plates and laser cutting a central opening in each of the plates for receiving a shaft for effecting rotation of the flywheel. The plurality of plates are laminated together by inserting fasteners in corresponding ones of the apertures in the plates. At least one knife is attached to the laminated plates for cutting wood material to form chips of the wood material as the flywheel is rotated.
