[0002] The utility model patent application of "Double-layer Roller Raymond Mill" with the authorization announcement number of CN203874844U is an improved device for fine powder processing. In its technical solution, a central shaft frame and a grinding ring are coaxially installed on the base of the grinding 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 frame. A fixed roller frame connected to the scraper knife frame 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 frame. 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 layer of grinding rollers.

[0003] The "Double-layer Roller Raymond Mill" utility model adopts a grinding method with two layers of rollers to gradually process the powder 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. Content of the Utility Model

[0005] The high-efficiency sand making machine capable of simultaneously processing powder and sand and solving the above technical problems includes a base. A central shaft frame and a grinding ring are arranged in the base. A hood cylinder is arranged on the base. A classifier is arranged on the hood cylinder. 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 then connects the transmission mechanism. The upper part of the main shaft of the main machine is coaxially sleeved with a scraper knife frame. A fixed roller frame connected to the scraper knife frame 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 frame. Two or more 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 layer of grinding rollers. The differences are as follows:

[0006] 1. A horizontal annular aggregate groove is arranged on the inner side wall of the hood cylinder. A scraping plate synchronously rotating with the main shaft of the main machine is arranged in the annular aggregate groove. An outlet I communicating with the annular aggregate groove is arranged on the hood cylinder. A discharge pipe I is externally connected to the outlet I.

[0007] 2. An outlet II is arranged at the bottom of the base and is located on the rotation path of the scraping knife. A discharge pipe II is externally connected to the outlet II.

[0008] Further, the scraping plate is driven by the fixed roller frame to rotate synchronously.

[0009] Furthermore, a material leveling plate is installed on the fixed roller frame, and the scraping plate is driven by the material leveling plate to rotate synchronously.

[0010] Advantages of the present utility model:

[0011] The high-efficiency sand making machine of the present utility model that can process powder and sand simultaneously expands the powder variety processing function on the basis of the original "Double-layer Roller Raymond Mill", transforms the single production of fine powder in the prior art into a multi-functional grinding equipment that can produce fine powder, fine sand and coarse sand simultaneously, and improves the compatibility of the equipment.

Specific embodiments

[0014] The technical solution of the present utility model will be further described below in conjunction with the embodiments shown in the drawings.

[0015] The high-efficiency sand making 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 4 is coaxially installed on the base 1, and a classifier is coaxially installed on the cover cylinder 4, as Figure 1 shown.

[0016] A hollow central shaft frame 2 and a grinding ring 3 are coaxially installed in the base 1. The lower part of the main shaft 5 of the powder grinding host is arranged in 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 frame 7 connected to the scraper holder 6. A material leveling plate 14 is coaxially installed on the fixed roller frame 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 frame 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-layer rollers or multi-layer rollers. The scraping height of the scraper 8 corresponds to the lower grinding roller 9, as Figure 1 shown.

[0017] A horizontal "L"-shaped folding plate is welded on the inner cylindrical wall of the cover cylinder 4 to form an annular aggregate groove 10. The position of the annular aggregate groove 10 is at the same height as the fixed roller frame 7. The annular aggregate groove 10 is provided with scraping plates evenly distributed in a circumferential manner. Each scraping plate is installed on the material leveling plate 14 through a corresponding connecting rod. One side of the cover cylinder 4 is provided with an inclined discharge pipe I 11. The upper end of the discharge pipe I 11 is communicated with the annular aggregate groove 10 through a discharge port I opened on the cover cylinder 4, as Figure 1 shown.
