cone crusher with crushing ratio, high efficiency, low energy consumption, product size uniformity and suitable for crushing hard ore and other advantages, which is widely favored by the dressing industry. however, the liner of the cone crusher is often subject to severe impact and is prone to severe wear. this can lead to uneven product size, reduced production efficiency and increased energy consumption and other issues, so the replacement of crusher liner is essential. replacement of the new liner is usually used in high temperature zinc alloy casting or room temperature high grade cement mortar casting method, in the production and maintenance process often appear broken wall and rolling sａnd wall loose, fixed difficulties and other issues, seriously affect the normal operation of production. according to past experience, the replacement of a cone crusher liner and casting time is about 7 to 10 days, the replacement cycle is too long, seriously affecting the normal production schedule, for this related personnel continue to explore the study, repeated practice accumulation, the development of the cone crusher liner filling new technology - epoxy fillers (crusher backing adhesive).
