Animal bedding is disclosed. The animal bedding comprises a juniper tree cut at ground level, the juniper tree having needles and a trunk. The juniper tree is naturally dried until the needles are brown, then ground using a screen that is 3 inches or less. The ground juniper tree is hammer milled and dust of 20 mesh minus is extracted from the hammer milled tree, which is then placed in a bagging machine and dust is vacuumed from the juniper tree. The juniper tree is then bagged.

There is provided a method for enhanced extraction of cannabis oil from a cannabis plant material, and a free-flowing powder consisting of particles of cannabis plant material for use in such method for enhanced extraction. The cannabis plant material is characterized by a cannabis strain and a cannabis plant part. The method comprising a step of comminuting said cannabis plant material to a powder of a preselected particle size distribution (PSD) characterized by 10≤Dv(90)≤100 μm as determined by laser diffraction particle size analysis prior to extraction process. The PSD is preselected in accordance with said cannabis strain and said plant part.

This invention relates to a process of comminution of iron ore or iron ore products (pellet feed, sinter feed, etc.) at natural moisture without the need to add water or to include a drying step in the process, that is technically and economically feasible. The comminution process of this invention uses at least one piece of equipment selected from the group consisting of roller press (HPGR), vertical roller mill (VRM), roller crusher (RC) and high acceleration screen of at least 10G.

The present invention discloses a same-cavity integrated vertical high-speed multistage superfine pulverizing device and method for walnut shells. The same-cavity integrated vertical high-speed multistage superfine pulverizing device for walnut shells includes a double-channel sliding type feeding device and a same-cavity integrated vertical pulverizing device. The same-cavity integrated vertical pulverizing device includes a material lifting disc and a same-cavity integrated vertical pulverizing barrel. A first-stage coarse crushing region, a second-stage fine crushing region, a third-stage pneumatic impact micro pulverizing region and a fourth-stage airflow mill superfine pulverizing region are disposed in the same-cavity integrated vertical pulverizing barrel. Walnut shells falling through the double-channel sliding type feeding device are uniformly lifted by the material lifting disc to a wedge-shaped gap of the first-stage coarse crushing region to be coarsely crushed, and coarsely crushed materials are finely crushed by the second-stage fine crushing region through a two-stage wedge-shaped direct-through gradually reducing gap. The third-stage pneumatic impact micro pulverizing region performs high-speed collision on finely crushed walnut shell particles, and walnut shell fine particles are carried by a high-speed airflow and are collided and violently rubbed to be pulverized. The microparticle grading is realized by the fourth-stage airflow mill superfine pulverizing region by using arc-shaped blades, and microparticles conforming to a particle size condition are attracted out through negative pressure attraction.

A fully automatic small arms demilitarization system includes individual infeed conveyance systems loaded at a single process initiation location; multiple hydraulic press stations fed by the individual infeed conveyance systems; and the multiple hydraulic press stations configured to crush one section of each weapon per cycle, incrementally crushing an entire length of each weapon, completely distorting each weapon to preclude restoration to a useable condition. The system further including an output system configured to output demilitarized weapons onto a common outfeed conveyance system that delivers the demilitarized weapons to a single recycle bin.
