The concave plate is a crucial wear part within the cone crusher, forming the fixed crushing surface in the crushing chamber. It is typically manufactured from high-manganese steel for superior impact and abrasion resistance. As the mantle gyrates against it, the concave plate's primary function is to facilitate the compression and breaking of raw materials into specified sizes. Its robust design ensures a consistent crushing cavity geometry, which is vital for maintaining optimal crusher performance, product gradation, and operational efficiency. Regular inspection and timely replacement of the concave plate are essential to safeguard the crusher's integrity and minimize downtime.
