Regarding the working principle of the crusher

When entering the crusher for inspection or problem-solving, it is necessary to wait until the crusher has completely stopped, notify the electrician to cut off the power, and hang a safety warning sign that reads "Maintenance strictly prohibited from closing"; After confirming that the power has been completely cut off, the maintenance personnel must disconnect the emergency stop switch of the equipment on site before entering the crusher. At the same time, there must be a dedicated person outside the crusher mouth for safety supervision.
