In its technical solution, a central shaft frame and a grinding ring are coaxially installed on the base of the grinding powder main machine. The lower part of the main shaft of the main machine is arranged in the central shaft frame and extends downward to connect the transmission mechanism. The upper part of the main shaft of the main machine is coaxially sleeved with a scraper knife holder. A fixed roller frame connected to the scraper knife holder is installed at the upper end of the main shaft of the main machine. Scraping knives are installed at the bottom of the scraper knife holder. The grinding roller devices are evenly distributed around the axis in a circular pattern and are divided into two groups. The grinding rollers of different groups of grinding roller devices are at different height positions in the grinding ring to form two layers of rollers. The scraping height of the scraping knife corresponds to the lower grinding roller.
[0003] The utility model of "Double-layer Roller Raymond Mill" adopts a grinding method with two layers of rollers to gradually process the powder material from coarse powder to fine powder. During the grinding process, the resistance is small, the power loss is small, and the fine powder generation rate is high. Utility Model Content

The lower part of the main shaft of the main machine is arranged in the central shaft frame and extends downward out of the base and connects the transmission mechanism. The upper part of the main shaft of the main machine is coaxially sleeved with a scraper knife holder. A fixed roller frame connected to the scraper knife holder is installed at the upper end of the main shaft of the main machine. Scraping knives are installed at the bottom of the scraper knife holder. Two groups or multiple groups of grinding roller devices are hinged and suspended at different heights of the fixed roller frame. The grinding rollers of each group of grinding roller devices are at different height positions in the grinding ring to form two layers of rollers or multiple layers of rollers. The scraping height of the scraping knife corresponds to the lower grinding roller. The difference is that:
[0006] 1. The cover cylinder includes a lower cover cylinder and an upper cover cylinder installed on the base. The lower cover cylinder includes an inclined upper opening. The upper cover cylinder includes a lower opening with the same inclined slope. The upper cover cylinder and the lower cover cylinder are sleeved at the opening. The lower opening of the upper cover cylinder is connected to the lower cover cylinder through a ring-shaped rib plate with the same slope.

[0013] The technical solution of the present utility model will be further described below in conjunction with the embodiments shown in the drawings.
[0014] The novel all-in-one machine of the present utility model that can process powder and sand simultaneously includes a base 1 fixedly installed on a concrete machine base. A cover cylinder is coaxially installed on the base 1, and a classifier is coaxially installed on the cover cylinder, as Figure 1 shown.
[0015] A hollow central shaft frame 2 and a grinding ring 3 are coaxially installed inside the base 1. The lower part of the main shaft 5 of the grinding powder main machine is arranged inside the central shaft frame 2. The lower end of the main shaft 5 extends downward outside the base 1 and is connected to a transmission mechanism. The upper part of the main shaft 5 is coaxially sleeved with a scraper holder 6. The upper end of the main shaft 5 is coaxially installed with a fixed roller holder 7 connected to the scraper holder 6. A material leveling plate 14 is coaxially installed on the fixed roller holder 7. A scraper 8 is installed at the bottom of the scraper holder 6 and is located inside the bottom of the base 1. Two or more groups of grinding roller devices are hinged and suspended at different heights of the fixed roller holder 7. The grinding rollers 9 in each group of grinding roller devices are located at the upper and lower height positions inside the grinding ring 3 to form two layers of rollers or multiple layers of rollers. The material scraping height of the scraper 8 corresponds to the lower grinding roller 9, as Figure 1 shown.
