Abstract: A continuous wet ball-milling separation device has a cylinder, which has a feeding section, a shearing section, and a crushing section in sequence from top to bottom. The feeding section is located at the upper portion of the device, and is provided with a liquid inlet, a material inlet, and a material distributor. The shearing section is located in the middle of the device, and is internally provided with shearing blades. The crushing section is located at the lower portion of the device, and is internally provided with stirring rods and crushing balls, and a grading discharge module is provided at the bottom of the crushing section. A grading discharge module is used in the device and a continuous wet ball-milling separation method applying the device. The device implements continuous operations of material crushing and grading by means of the material distributor, wet shearing, wet crushing, and wet grading.

Abstract: A service control is downloaded and installed. First software information installed by the user system is uploaded by the service control to a cloud server side. The first software information includes a software list, or the software list and personalized configuration files of each software. When needing to restore the user system, second software information of the user system is obtained from the cloud server side. Software of the user system is installed, based on the second software information obtained from the cloud server side.

Abstract: The present invention relates to a radio with a key and knob combination. To solve problems such as inconvenience caused by the independent PTT key and volume control knob on the traditional radios, the present invention provides a radio with a key and knob combination, comprising a PPT key unit and a volume control unit, wherein the key is installed inside a central cavity of the knob, which is a hollow knob, to form the key and knob combination. Rotation of the knob (106) may drive the shaft (102) and the toggle piece (111) to rotate synchronously, and then toggle the volume switch (112), while the pressed key (101) may cause the shaft (102) moving axially to toggle the PTT switch (103). When operating the radio with a single hand, users can both press the PTT key to initiate a call and rotate the knob to adjust the volume level by a thumb or a forefinger, and the operation is very convenient.
