Description

Technical Field

[0001] This utility model relates to the field of grinding technology, specifically a weight-reducing frame-type wet grinding mill. Background Technology

[0002] A wet grinding mill, also known as a wet milling mill, is classified into several types based on its operation: gold grinding mill, amalgamation mill, iron grinding mill, and electric mill; and based on its structure: roller mill, double-roller mill, and triple-roller mill. The wet grinding mill is a modern improvement on the ancient stone mill. It is used for grinding various ferrous metals, non-ferrous metals, and non-metallic minerals, as well as for grinding, beneficiating, and processing rare and precious metals such as gold and silver. It is the preferred grinding equipment for many small and medium-sized ore dressing plants and powder mills. For the sample applicant company, it is used for large-scale ore grinding, and can also be used for grinding refractory brick materials.

[0003] Existing technology CN202510271225.9 describes a wet grinding mill that addresses the technical problem that only one guide groove bears the weight of the grinding wheel, making the guide groove and guide plate prone to damage and affecting the service life of the wet grinding mill. However, it still uses the traditional grinding wheel drive rotation for grinding.

[0004] Furthermore, our company previously applied for CN202311720005.7, a mineral powder crushing device and its usage method, which is similar to this application in terms of mixing. However, it was found that the device was large in size, making it inconvenient to transport. Therefore, a weight-reducing frame-type wet grinding mill was designed to reduce the weight of the device and facilitate the installation of the gearbox.

[0005] To address these issues, we provide a weight-reducing frame-type wet grinding mill. Utility Model Content
