A counter-rotating pin mill for grinding food products includes a housing assembly comprising a first and a second housing part. A first and a second grinding shaft are arranged coaxially in the housing assembly on a grinding axis. A first grinding disk is arranged on an end of the first grinding shaft. A second grinding disk is arranged on an end of the second grinding shaft. The first and the second grinding disks are parallel to each other. A bearing device is formed by at least two slide assemblies arranged parallel with the grinding axis in the first housing part. The at least two slide assemblies comprises a slide bushing arranged in the first housing part and a slide axle guided in the slide bushing and being connected with the second housing part. The first and/or the second housing part is displaceable along the grinding axis via the bearing device.

A mill system for reducing the material size of input material, the system including a plurality of strike plates, preferably of ceramic, embedded within an interior layer of a housing, wherein the interior layer includes tiles made preferably of ceramic; a rotor having one or more rotor blades; a driveshaft; and a motor; wherein the motor powers the drive shaft to rotate the rotor; wherein the rotor blades move input material against the plurality of strike plates.

An apparatus and method of mechanical milling and grinding of various materials at temperatures ranging from sub-ambient conditions to well-below their ductile-brittle transition temperature (DBTT) are presented. In one embodiment the present invention entails the design of a cryogenic milling chamber compatible with horizontal high-energy mills. The new design and configuration of the milling vessel provides robust and efficient cryomilling of various materials with no contact between the cryogen and the powders. Some embodiments of the invention improve the heat removal rate from the non-uniform heat load generated by the impact energy deposited into the chamber wall by the milling media.

Disclosed is a nano pulverizing device for processing reconstituted rice flour which includes a bottom plate, support legs are fixedly connected to corners of a lower surface of the bottom plate, a housing is arranged on an upper surface of the bottom plate, and a rotating motor is arranged on the lower surface of the bottom plate. The rotating motor penetrates through the lower surface of the bottom plate and extends to the upper surface of the bottom plate, and a crushing device is rotationally connected to one end, extending to the upper surface of the bottom plate, of the rotating motor. A support frame is fixedly connected to an inner wall of the housing, a support plate is fixedly connected to a lower surface of the support frame, and a flexible plate is fixedly connected to a lower surface of the support plate.

The present disclosure is broadly concerned with processing equipment and methods for processing of a biomass feedstock into one or more biomass particles of reduced size, and in particular, hemp. The vertical impact liberating equipment and methods can process whole hemp stalks into hemp particulates comprising distinct fractions of hemp hurds, bast fiber, and fines. Advantageously, in preferred embodiments, the biomass feedstock is pulled through a defined gap and into a defined chamber. This action causes a successive decrease and increase of pressure within the biomass feedstock, yielding the one or more biomass particles of reduced size.

A wear protection component includes an elastic material layer and a reinforcing support. The elastic material layer is bonded to the reinforcing support, and the wear protection component is bent into a curved shape. In an area delimited by an outer periphery of the reinforcing support, the wear protection component includes one or more local stress relief areas in which the elastic material layer is not bonded to the reinforcing support.

A material shredder is provided for shredding recyclable materials. The shredder includes a rotor with multiple cutting blades arranged around its outer surface. These blades have cutting edges that form a cutting circumference. The rotor is enclosed by a housing, creating a cutting chamber between the rotor and stator. Inside this chamber, the cutting blades interact with at least one counter blade mounted on the inner surface of the stator, spaced to form a cutting gap. The stator also includes at least one outlet with a screen that helps define the cutting chamber. The shredder further includes a grinding device with an abrasive holder, located outside the cutting circumference. Both the abrasive and the screen can be moved to adjust their distance from the cutting circumference. The invention also includes a shredding plant with the shredder and a method for maintaining the shredder.
