Embodiment Construction

[0019] Such as figure 1 , figure 2 Shown is a rod mill for grinding calcified roasted clinker provided by the present invention, which is easy to replace and can effectively reduce serious damage to the abrasive cylinder caused by the grinding system. The rod mill includes an abrasive cylinder 1 and a grinding assembly 2, the grinding assembly 2 is arranged in the abrasive cylinder 1, and the rod mill also includes an integrated quick-detachable inner liner 3, the The grinding inner wall of the abrasive barrel 1 is protected by the integrated quick-release inner liner 3 . The present application replaces the existing inner lining boards fixed in the abrasive barrel 1 one by one by connecting bolts by adding a set of integrated quick-release inner lining plate 3, and makes the grinding of the abrasive barrel 1 The inner wall is protected by the integrated quick-release inner liner 3 . Since the integrated quick-release inner liner 3 is connected by a quick-release connectio...

Abstract

The invention belongs to the technical field of metallurgy production equipment design and manufacturing, and discloses a rod mill, in particular a rod mill used for calcium roasting clinker grinding. The rod mill for the calcium roasting clinker grinding is convenient to replace, and serious damage to an abrasive cylinder by a grinding system can be effectively lowered. The rod mill comprises the abrasive cylinder and abrasive components arranged in the abrasive cylinder. The rod mill further comprises an integrated quick-disassembly type interior lining panel; and the grinding inner wall of the abrasive cylinder is protected through the integrated quick-disassembly type interior lining panel.

Description

technical field [0001] The invention relates to a rod mill, in particular to a rod mill for grinding calcified roasted clinker, and belongs to the technical field of design and manufacture of metallurgical production equipment. Background technique [0002] A vanadium product factory in Xichang uses calcified clinker acid leaching process to produce vanadium oxide, which has very high requirements on clinker particle size. If the particle size is above +80 mesh, the leaching effect is poor, and the leaching rate is less than 75%; while the clinker particle size is too fine, above -240 mesh, the leaching slurry is relatively viscous and difficult to filter, which is not conducive to large-scale production. The leaching effect is the best when the clinker particle size is between -120 and 240 mesh, and the leaching rate reaches more than 95%. But at present, it is only limited to the laboratory that can meet such particle size requirements. In the actual production process, a...
