Background
The model 5 ~ 14m of common semi-autogenous mill (also including the autogenous mill) has tens kinds, and the diameter and the length of every kind of semi-autogenous mill barrel are different, and every semi-autogenous mill model has tens not unidimensional and figurative welts, including barrel welt, angle welt, feeding end welt, ore pulp lifting mechanism, middle row material board, row material grid board etc..
In the prior art, the thickness of the lining plate of the semi-autogenous mill is 50-450 mm, the length is about 2m, the bottom mounting surface of the lining plate is in contact with the inner mounting surface of the circular cylinder body, the bottom mounting surface of the lining plate is an outer convex cambered surface, and the inner mounting surface of the circular cylinder body is an inner concave cambered surface. Usually, the periphery of the installation cambered surface at the bottom of the semi-autogenous grinding lining plate and the part near the screw port are in contact with the cylinder body, and the rest part is suspended. The main starting points of the design are as follows: firstly, a riser design is used in the casting process, and the bottom of the lining plate is convenient to clean; secondly, the bottom of the concave cylinder body is uneven or has impurities, which affects the fitting degree of the mounting surface. At present, the bottom of the mounting surface of the semi-autogenous grinding lining plate is in local point contact, the contact surface of the lining plate is only in contact with the cylinder body in about one fifth of the area, the high manganese steel lining plate is easy to deform, so the gap is large, and the gap between the lining plate and the lining plate is about 10-40 mm.
The lining board of the semi-autogenous mill belongs to casting and forging-rolling molding at present, and the lining board is directly used by a heat treatment process after molding. The deformation caused by heat treatment basically does not need machining in production, and the deformation after heat treatment causes the mounting surface of the lining plate to be uneven in the practical application process, so that cracks are easy to generate.
The clearance between the lining plate and the lining plate is too small to be installed and too large to be matched with each other tightly. The clearance between welt and the welt is 10 ~ 40mm usually, adopts the pad rubber pad in the middle of the clearance, and the ore impact force is concentrated, causes the welt to fall the piece or the installation screw is cut off, still can cause the barrel to warp when serious.
The semi-autogenous grinding lining plate formed by forging and rolling has the advantages that the bottom of the lining plate is formed by machining, the process of forming the arc surface is complex, the lining plate is made of wear-resistant steel, the lining plate can be processed by adopting an annealing process in the processing process, and quenching and tempering are performed after the processing. Deformation exists in the heat treatment process, and cracks are easily generated on the lining plate in the application process due to the fact that gaps are generated on the binding surface in the installation process.
After casting and forging-rolling forming quenching, abrasion resistance is required, so that it is difficult to trim deformation by machining.
