A food recycler can include a bucket with a certain configuration for processing waste food. A bucket includes an interior surface having thereon a set of projections. A grinding mechanism includes a first arm connected to a rotational member, the first arm having a first distal end adjacent to the interior surface of the bucket and that has notches that are complementary to the projections. A second arm has a second distal end also having notches complementary to projections. Waste food is processed with the grinding mechanism.

An autogenous impact mill (10) is operative to size reduce friable material particles processed through operation of the mill. At least one impeller (58) rotatable within an interior area (44) of a housing (12) of the mill is operative to produce one or more air jets. The air jets are operative to suspend material particles using the Coanda Effect. Other particles moved by the air jets bounce off ricochet bars (74) and impact suspended particles so as to break and reduce the particles to a suitable size to pass through a screen (110) to an outlet opening (42).

A solid material grinding method and device with an adjustable discharge size includes a grinding disc housing, and a movable grinding disc and a stationary grinding disc provided in a grinding disc cavity of the grinding disc housing coaxially with grinding surfaces opposite to each other. The movable grinding disc is driven to rotate in the grinding disc housing, thereby grinding materials between the movable grinding disc and the stationary grinding disc. The movable grinding disc is further connected to a pushing mechanism, and the pushing mechanism adjusts the distance between the movable grinding disc and the stationary grinding disc in a push-and-pull manner. A top rectifying blower and a side edge rectifying blower respectively blow gas from an upward side and a lateral side of the movable grinding disc and the stationary grinding disc. A central rectifying blower blows gas to the center of the stationary grinding disc.
