The invention provides a grinding device for food processing, which includes an arc-shaped grinding box for grinding Chinese prickly ash, a support ring for supporting the arc-shaped grinding box, and a variable cavity for grinding the pepper inside the arc-shaped grinding box A grinding mechanism, wherein a support ring is fixedly connected to the surface of the arc-shaped grinding box, relates to the field of food processing. The grinding device for food processing is based on the problem that powder is easily adsorbed on the grinding device and occupies the grinding space in the existing pepper grinding process. A special structure that can change the grinding space is designed and uses the thermal expansion structure to control the powder mixing and grinding at the grinding structure in real time. Falling, thus effectively solving the problem that the general grinding device is difficult to separate the pepper fine powder during the grinding process. The fine and smooth pepper powder is not only easy to adhere to the grinding device and affect the grinding effect, but also takes up a lot of grinding space. Problems that affect the efficiency of food processing.

The invention discloses a device for preparing graphene-doped hydrogen storage materials, the structure of which includes a controller, a heat sink, fixed feet, a material holding platform, a preparation port, a preparation tank, a control host, and a doping tank . The graphene raw material in the doping tank of the present invention enters through the scraper groove, and the scraper groove and the discharge ring are fixedly arranged, and the raw material is guided to the discharge ring and the grinding insert by the dial block when the grinding mechanism rotates. The crushing process is carried out in the area matched with the ring, and then it enters the dispersing component for dispersing and blanking, which can avoid the reduction of hydrogen permeability caused by piled material, and the air compressor can generate gas under the drive of the built-in drive shaft to pneumatically control the dispersing component. , to avoid the blockage of graphene raw materials, after the overall use, the graphite flakes can be crushed with high precision, and the raw materials are effectively prevented from agglomerating during the blanking process, forming a powdery falling state, which greatly improves the hydrogen doping Permeability, hydrogen storage effect is higher.

The invention relates to a method for preparing Portland cement, which uses a ball mill, which includes a bottom plate, a mounting plate, a grinding device, and a wall scraping device. The specific method flow for preparing Portland cement by using the ball mill is as follows: Clinker preparation, calcined clinker, clinker cooling, cement molding and inspection and packaging, grinding device includes drive motor, cylinder, inner lining plate, feeding pipe, material inlet, material outlet, material rack, compartment plate and steel The ball and the wall scraping device include a support rod, a lifting cylinder, a connecting rod, a scraping head, a fixed rod and an auxiliary mechanism. In the present invention, when the raw material is ground into powder through the grinding device, the powder adhered to the inner wall of the cylinder is scraped off in time through the wall scraping device to prevent waste and at the same time avoid the impact of the buffering effect on this part of the powder Reduce the grinding effect of steel balls. In addition, the wall scraping device can also regularly clean the scraping head to prevent too much powder adhering to the scraping head from affecting the scraping effect.
