The movable cone lining plate and the fixed cone lining plate are in direct contact with materials, the abrasion is fast, periodic replacement is needed, and the lining plate is required to be more simple and better to disassemble and assemble. The fixed cone lining plate is arranged in the fixed cone assembly and positioned by a plurality of wedge block groups, the fixed cone lining plate is arranged on the fixed cone, and the wedge block groups are also arranged on the fixed cone. A key part of a fixed cone crusher.

The structure of the multi-cylinder cone fixed cone of the multi-cylinder cone crusher at present has the following disadvantages: 1. the two side walls of the fixed cone at the position for mounting the lining plate are very thin and have poor strength; 2. design defect, hoist and mount are very troublesome, 3. need install the fixed welt of adapter ring, adapter ring bears very big load when the breaker carries out crushing operation, especially when the breaker transships, and the adapter ring became invalid very easily to the very easy reason of instantaneous volume impact load, or the locating pin fracture makes adapter ring dislocation etc. and the inefficacy and the dislocation of adapter ring will lead to the fixed cone welt to become flexible or even drop to make the breaker inefficacy.
