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.

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 system and method for freezing and breaking down tires or other materials is disclosed. The system and method for freezing and breaking down tires includes using a shredder to shred the tires, using a filter to screen the tire shreds, using a water sprayer to rinse the tire shreds, using a freezing tunnel to freeze the tire shreds before they are crushed into tire grains, using a magnet to remove any metallic fibers, filtering out any oversized tire grains for re-freezing and re-crushing, and using a separator to separate out any oversized or undersized pieces before bagging the final tire grains for re-use and recycling.

Coconut crumb can serve as an infill material on synthetic turf fields in the place of tire crumb. The crumbs are less than 10 mm big and have smooth corners and edges. The process of producing the coconut crumb involves successive grinding or milling processes that reduce the inner hard shell of the coconut to particles of an appropriate size for infill, while screening out the unwanted material from being included in the infill.

A preparation of niobium nanoparticles, its use, and a process for obtaining it by comminution, that is, a top-down process. The preparation of nanoparticles has a particular composition, purity, granulometric profile, and specific surface area, being useful in a variety of applications. Also taught is a process for obtaining nanoparticles of mineral species containing Niobium, through controlled comminution and without chemical reactions or contamination with reagents typical of the synthesis of nanoparticles. The preparation of niobium nanoparticles provides the large-scale production of niobium pentoxide nanoparticles with high purity, determined granulometric profile and very high specific surface area, enabling its use in practice in several industrial applications.

The invention relates to a continuous dry granulation method and non-invasive monitoring and control of the dry granulation method. The invention further describes a dry granulation system and uses thereof. In particular, the non-invasive monitoring methods employ a sound, force, strain, vibration and/or acceleration sensor in order to determine the mechanical strength of a compacted material during a dry granulation process. Further, the compaction parameters of the compacting unit of the granulation process may be controlled to maintain a target mechanical strength of the compacted material.

A method includes separating, in a first stage of separating, crushed ore material by size into a first fines stream and a first coarse stream; grinding the first coarse stream in a second stage of grinding; feeding the product of the second stage of grinding back to the step of separating; feeding the first fines stream from the step of separating to a recovery circuit; producing a rejected stream from the recovery circuit of crushed ore material that does not meet the target mineral size; separating, in a second stage of separating, the rejected stream from the recovery circuit into a second fines stream and a second coarse stream; grinding the second coarse stream in a third stage of grinding; and feeding the product of the third stage of grinding back to the recovery circuit.
