Description

Technical Field

[0001] The utility model relates to the technical field of raw material grinding, in particular to a wear-resistant raw material grinding mill. Background Art

[0002] In the cement production process, raw materials need to be ground. When grinding raw materials, grinding rollers are used to grind raw materials into powder. The limestone used in the raw material workshop contains a high amount of crystalline silicon (12.5% ​​to 13%). The hardness of limestone is relatively large and difficult to grind, causing the wear-resistant layer of grinding rollers and grinding discs to wear out quickly.

[0003] The existing Chinese utility model patent with reference announcement number: CN212068894U discloses a limestone raw material grinding device, including: a first grinding bin, a second grinding bin, and a circulating filter bin; a feed port is provided on the top of the first grinding bin, the feed port extends to the inside of the first grinding bin, and a grinding roller is correspondingly provided below the feed port; a first discharge port is provided at the bottom of the first grinding bin; the bottom of the first grinding bin is connected to the second grinding bin, and a servo motor is provided on one side of the second grinding bin, and the servo motor is connected to and drives the grinding rod for grinding; a second discharge port is provided at the bottom of the second grinding bin; the bottom of the second grinding bin is connected to the circulating filter bin; a filter plate and a guide plate are provided inside the circulating filter bin,

[0004] The filter plate is provided with a filter net, and a discharge port and a recovery port are provided at the bottom of the filter circulation bin; multiple grindings are performed in an integrated manner, so that the powder is ground into a high degree and has a good grinding effect, which significantly improves the grinding efficiency and achieves the purpose of energy saving.

[0005] Based on the search of the above patents and combined with the equipment in the prior art, it was found that the limestone used in our company's raw material workshop contains a relatively high amount of crystalline silicon (12.5% ​​to 13%), and the hardness of the limestone is relatively large, making it difficult to grind.

When grinding the limestone, the volume of the limestone is different, resulting in the ground product not meeting the demand, resulting in the need for subsequent screening and secondary grinding. The existence of these problems has affected the use of the device. Utility Model Content
