An automatic grinder and a grinding method thereof. The grinder includes a control structure and at least one material container assembly. The control structure includes a driving assembly and a connecting structure connected to the driving assembly. The material container assembly includes a material container body (20), a grinding head (22) fixedly connected to the material container body (20), and a grinding sleeve (25) rotatably connected to the grinding head (22). A recess (201) is provided on the material container body (20), and the connecting structure is engaged with the recess (201). The grinding head (22) is fitted into the grinding sleeve (25), and the grinding head (22) and the grinding sleeve (25) define therebetween a material compartment (40) for accommodating a material. The driving assembly drives, via the connecting structure, the material container body (20) to rotate. The material container body (20) drives the grinding head (22) to rotate. The grinding head (22) moves relative to the grinding sleeve (25), such that the material between the grinding head (22) and the grinding sleeve (25) is ground into powder. The automated grinder is provided with different grinding sleeves and grinding heads for grinding a variety of materials, and prevents the introduction of impurities during feeding, thereby preserving the original flavor of the material.

A medicine grinder has a grinding assembly having a ring burr and a frustoconical burr being mutually rotatable relative to each other. The ring burr is tubular. The frustoconical burr is disposed within the ring burr and has multiple rough grinding edges, multiple recesses, and a non-grinding portion. The multiple rough grinding edges surround a center of the frustoconical burr. Each one of the grinding edges spirally extends about the center of the frustoconical burr. The multiple recesses are divided by the multiple rough grinding edges. One of the multiple recesses has a capacity being larger than a capacity of each one of the other recesses to define a non-grinding portion. Therefore, multiple receiving spaces are formed between the frustoconical burr and the ring burr.

A system for monitoring at least one motion parameter of the main shaft of a gyratory or cone crusher. The system includes a sensor, such as a magnetometer, positioned within close proximity to a magnetic element, such as a lifting lug, formed on a top end of the main shaft. When the main shaft rotates or moves vertically, the movement creates a change in the magnetic flux, which is sensed by the magnetometer. The change in the magnetic flux is sensed by the magnetometer and an output signal is generated. A controller receives the output signal and determines at least one motion parameter based upon the detected changes in the magnetic flux. In one embodiment, a permanent magnet can be the magnetic element or can be inserted into the lifting lug to enhance the magnetic flux changes caused by the rotational movement or vertical movement of the main shaft.

A novel device for hand grinding coffee is disclosed. The device preferably includes a base, a stanchion disposed about the base, and a gear box, a burr collar, and a flywheel each extending away from the stanchion. The flywheel includes a handle for turning it. The device further includes a gear mechanism including a main driven shaft. The main driven shaft extends downward from the gear box. There also is a burr mechanism driven by the gear mechanism. The device may include a variable transmission mechanism having a first gear set and a second gear set selectively engageable to drive the main driven shaft. The device may also include a tumbler having a ground chamber. A distribution member is configured to rotate within the ground chamber of the tumbler during operation of the device.
