凹面/碗形衬板

凹面/碗形衬板是锰钢铸件，构成圆锥破碎机和旋回破碎机的固定破碎表面。它安装在上框架（碗形）内部，与破碎壁配合，通过压缩力破碎岩石。该部件定义了破碎腔几何形状，直接影响产品粒度、生产能力和破碎机效率。其设计具有特定轮廓（标准、粗、细），以实现所需的粒度减小。

凹面形成固定破碎表面，旋转的破碎壁对其压缩给料物料。当破碎壁在凹面内旋回时，岩石通过反复压缩循环被破碎。衬板的轮廓控制啮合角和破碎间隙，决定破碎比和通过量。磨损通过磨蚀和冲击发生，逐渐改变破碎腔几何形状，直至需要更换。

The concave creates a fixed crushing surface against which the rotating mantle compresses feed material. As the mantle gyrates within the concave, rocks are crushed through repeated compression cycles. The liner's profile controls the nip angle and crushing gap, determining the size reduction ratio and throughput. Wear occurs through abrasion and impact, gradually changing the chamber geometry until replacement is required.
