The invention discloses a stone surface polishing coating agent, and preparation method and application thereof. The stone surface polishing coating agent is characterized by comprising the following constituents in percentage by weight: 30-40% of nano-scale silicon dioxide, 5-8% of acrylic resin, 5-8% of epoxy resin, 8-12% of AEO (Primary Alcobol Ethoxylate) emulsion, 0.1-0.2% of coupling agent 560#, 1-2% of hydroxyl silicone oil and 25-50% of water. The stone surface polishing coating agent can be used on surface of natural stone and artificial quartz stone to keep the stone surface fresh and bright longer, and the antifouling effect is stronger.

The invention discloses natural stone crushing and grinding equipment. The natural stone crushing and grinding equipment comprises a machine body, a counter-impact crushing cavity is formed in the machine body, a feeding port communicating with the outside of the machine body is formed in a right side wall of the counter-impact crushing cavity, a crushing and grinding cavity is formed in the lowerside of the counter-impact crushing cavity, a counter-impact crushing and discharging port communicating with the crushing and grinding cavity is formed in a lower side wall of the counter-impact crushing cavity, and a transmission cavity is formed in the rear side of the counter-impact crushing cavity. The natural stone crushing and grinding equipment is simple and convenient to operate and lowin manufacturing cost, stone can be subjected to first-time crushing through repeated impact between a plate hammer and a first counter-impact plate and between the plate hammer and a second counter-impact plate, and can also be subjected to second-time crushing through extrusion between an extrusion wheel and an extrusion plate, and the crushed stone can be screened through a screen swinging up and down and finally can be ground through a second grinding plate and a first grinding plate.
