During the use of the jaw crusher, with the gradual wear of the liner, the discharge port continues to increase, thus making the product size larger. In order to obtain a qualified product size, the jaw crusher is equipped with a discharge port. The adjustment device can control the product size according to this adjustment device. There are two adjustment methods as follows
(1) Wedge adjustment. It is used between the rear thrust plate seat and the rear wall of the frame It can be adjusted by the wedge plate. Make one of the wedge plates rise and fall along the rear wall of the frame, and the discharge port can be reduced and enlarged. Using this method to adjust the size of the discharge port, you can achieve stepless adjustment. Convenient and labor-saving, and no need to stop, generally only suitable for small and medium-sized jaw crushers.
(2) Gasket adjustment. Put a set of gaskets of the same thickness behind the support seat of the rear thrust plate and change the gasket You can adjust the size of the discharge port. When adjusting the discharge port, you must first loosen the nut and the pull rod spring cap, and then increase or decrease the number of gaskets. After the discharge port is adjusted, Tighten the nut and adjust the nut on the spring. This method can also achieve multi-level adjustment, which is more convenient for adjustment, and at the same time can make the machine structure compact and reduce the mass, but it must be stopped during adjustment. This method is commonly used On large and medium-sized jaw crushers.
Through the above two methods, we can easily and quickly control the product size by adjusting the discharge port. However, if the equipment is worn out, it is necessary to frequently replace the vulnerable parts.
