Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of semi-autogenous grinding mill equipment, specifically a large semi-autogenous grinding mill liner that is easy to disassemble. Background Technology
[0002] The semi-autogenous mill is a core piece of equipment in the metallurgical industry that achieves material crushing through the impact of the ore itself and the grinding action of steel balls. Its working principle combines the impact grinding characteristics of an autogenous mill with the media grinding effect of a ball mill, with a steel ball filling rate typically ranging from 8% to 12% (up to a maximum of 15%). Developed since the 1960s, it has evolved into mainstream process systems such as single-stage process, SAB process, and SABC process. This equipment is widely used in gold, copper, and iron mines, demonstrating advantages in high processing capacity and low energy consumption when handling high-hardness ores. Through technological improvements such as the modification of the arc-shaped discharge end, innovation in liner materials, and optimization of media gradation, ore discharge efficiency can be effectively improved and the accumulation of stubborn rocks reduced.
[0003] The liner is directly attached to the inner side of the mill body steel plate, which is equivalent to a "protective layer". It replaces the wear of the mill body steel plate by its own wear, avoiding the mill body from being directly washed and impacted by materials, which would cause deformation or cracking, and fundamentally extend the service life of the mill body.
[0004] In the prior art, the liner is usually a one-piece structure. When the liner is damaged beyond repair, the entire liner needs to be replaced to ensure the normal operation of the semi-autogenous mill, resulting in waste. Utility Model Content
[0005] To address the aforementioned problems, this utility model proposes a large semi-autogenous grinding mill liner that is easy to disassemble, thereby resolving the technical issues raised in the background section.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A large semi-autogenous mill liner that is easy to disassemble includes a positioning mechanism and a mounting plate. The positioning mechanism includes a fixing ring with multiple clamping plates extending from its outer end. The mounting plate has multiple mounting holes on its side end face, with each mounting hole located between every two clamping plates, and a mounting plate installed between every two clamping plates.
[0007] Furthermore, each of the mounting plates has a recessed mounting groove on both sides, and each mounting groove has a corresponding fixing hole on both sides. The mounting plates are then fitted between the opposite mounting grooves of the two mounting plates.
[0008] Furthermore, corresponding fixing holes are provided on both sides of the mounting plate at the positions of fixing holes one and fixing holes two, and bolts are used to fix the fixing holes one and two.
[0009] Furthermore, each end face of the fixing ring corresponding to the mounting hole has a fixing hole three.
[0010] Furthermore, the lower end of the mounting plate has a protruding plug that is adapted to the mounting hole. The plug has a fourth fixing hole, and the fourth fixing hole is bolted to the third fixing hole.
[0011] The beneficial effects of this utility model are as follows: This utility model features a detachable structure for the mounting plate and fixing ring, with multiple individual mounting plates. When a mounting plate is damaged, it can be removed individually without replacing the entire plate, saving materials. During installation, inserts are used to insert into the mounting holes to ensure the longitudinal stability of the individual mounting plates. The mounting groove of the clamping plate is fixed to the mounting plate, ensuring the lateral stability of each individual mounting plate. Installation is simple and replacement is more convenient.
