A refiner for refining of lignocellulosic material includes a rotor disc and a stator disc. The rotor disc includes a first refining segment that includes a plurality of first protruding structures for grinding of the lignocellulosic material. Each of the first protruding structures is defined by a first height. The stator disc is arranged opposite the rotor disc and includes a second refining segment that includes a plurality of second protruding structures for grinding of the lignocellulosic material. Each of the second protruding structures being defined by a second height. The first height is at least three times larger than the second height.

The present invention relates to the field of grinding equipment, in particular to a powder grinder, comprising a power mechanism, a grinding mechanism, and a feeding mechanism. The feeding mechanism comprises a bowl and a base. The bowl is detachably installed on the base, and the power mechanism is detachably installed on the bowl. The first discharge opening is arranged in the middle of the bowl, and the second discharge opening is arranged in the middle of the base. An adjusting plate is rotatably installed on the base. The third discharge opening is arranged in the middle of the adjusting plate. An adjusting ring is arranged between the bowl and the base. The second connecting assembly is arranged between an inner edge of the adjusting ring and an outer edge of the adjusting plate. A bearing is arranged in the bowl. One end of the bearing is connected to the power mechanism, and the other end of the bearing passes through the first discharge opening, the third discharge opening, and the second discharge opening in sequence and is connected to the grinding mechanism for separate removal and cleaning of the bowl, the base, and the grinding mechanism. When cleaning, the power mechanism can be separately detached, which effectively prevents liquid from entering the inside of the power mechanism.

A grating apparatus grates an object to be grated, and includes an upper mill including an upper mill grinding surface and an opening portion in a center of the upper mill grinding surface, a lower mill located below the upper mill and including a lower mill grinding surface abutting on the upper mill grinding surface, and a core at least partially located in the opening portion. The core includes a plate-shaped portion which rotates, and an engagement portion engaged with an object to be grated is provided in a peripheral end surface of the plate-shaped portion.

The invention relates to methods of extracting DNA from seeds, said method comprising pretreating said seeds by soaking the seeds in a pretreatment solution comprising an alkali in a concentration sufficient to soften said seed; crushing said seeds; extracting said DNA from said crushed seeds. Methods also relate to the use of pretreatment solutions which further comprise an osmoticum. A method of fragmenting plant material such as seed, a method of recovering extraction medium from seed fragmentation and a process of extracting a seed component from crushed seed material are also described.

A rotary grinding mill for that improves the rotary grinding mill process. A milling assembly that comprise an offset ripper blades to limit the noise applied to the unit, cutting edges on the milling assembly blades, and an trailing blade edge that is angled creating a milling fan blade. The milling fan blade creates an air flow through the mill assembly. A collection container that utilized a plurality of cyclonic air flow patterns and filters to remove particles from the air. A rotary grinding mill comprising a mill housing, a hopper, and collection container, such that the grinding mill may be stored in a single unit.

The present invention provides systems and methods for production using manual labor. The present invention involves the transition of energies to perform labor. The transition involves manual labor energy turning into kinetic energy and further transition of the kinetic energy into mechanical or electrical energy used for performing designated labor.

A degerminator having a base, a plate with a plurality of protrusions, and a clamp that engages the plate to removably secure the plate to the base. A degerminator having first and second plate assemblies and an enclosure that surrounds the first plate assembly. The second plate assembly has a seal that moves between deflated and inflated positions. The second plate assembly moves between a first position, in which it does not engage the enclosure, and a second position, in which the seal engages the enclosure when inflated. A degerminator having a frame, first and second plate assemblies, supports and guides each coupled to the frame or the second plate assembly, and actuators each coupled to the frame and the second plate assembly to move the second plate assembly relative to the first plate assembly. A removable wear ring may protect a side wall of the enclosure.

The subject of the present invention is a method for processing electrical and electronic components in order to recover valuable materials, such as the metals contained in printed circuit boards. According to this method, the electrical and electronic components are pre-shredded mechanically and then mixed with a liquid before they undergo wet milling (5).

An improved grinding mill that utilizes mill stones that minimizing the mechanical processes required to regulating the mill stones and allow an user to gain quick and easy access to the mill stones by removing a hopper. In addition, to provide a base frame for the mill that secures both mechanical and electrical parts including the mill housing to reduce manufacture and repair time.
