The present invention relates to a crushing device for raw materials in cement production, which comprises a housing. There is a crushing chamber inside the housing. A main shaft is installed in the crushing chamber. A rotor disc is connected to the main shaft. Hammer heads are provided on the rotor disc. First cushion blocks are arranged on the hammer heads. A counterattack plate is movably connected to the inner wall of the crushing chamber. Second cushion blocks are arranged on the side surface of the counterattack plate facing the rotor disc. Both the first cushion blocks and the second cushion blocks are integrally formed regular pentagonal prism structures composed of one side surface of a regular triangular prism and one side surface of a regular quadrangular prism. The first cushion blocks form crushing edges facing counterclockwise. The second cushion blocks are identical in shape and size to the first cushion blocks. The regular quadrangular prisms of the second cushion blocks are detachably connected to the counterattack plate. The second cushion blocks form crushing edges facing the rotor disc. The crushing device can automatically remove high-hardness impurities during the production process, eliminating the need for manual removal of metal impurities or high-hardness stones and ensuring production efficiency.

The present invention relates to a refractive index sensor based on a metal nanowire plasmon microcavity, which primarily comprises a substrate, a metal film, and metal nanowires. The substrate and metal film are both lamellar, with the metal film positioned between the substrate and the metal nanowires, the two layers being in contact. The metal nanowire is a regular pentagonal prism positioned on the other side of the metal film, with one cylindrical surface of the regular pentagonal prism in contact with the metal film. The two metal nanowires are positioned in parallel. The substrate is made of silicon or sapphire, the metal film is made of gold or silver, and the metal nanowires are made of gold or silver. The microcavity structure of the present invention can flexibly perform sensing tests on two-dimensional materials of different sizes by modulating the cavity length, offering the advantage of flexible adjustability. The present invention has a simple structure and utilizes obliquely incident p-polarized white light excitation, resulting in simple excitation conditions. The metal nanowires, two-dimensional materials, and cavity length are all on the micrometer scale, facilitating integrated applications.
