1. Preparation before startup: (1) The following items must be checked before startup: Whether the power supply voltage meets the requirements. If the voltage is lower than 360 V, it is not allowed to start up. Check whether the electrical circuit meets the drawing requirements. (2) Check whether the connecting bolts and fastening screws are tightened, especially the connecting bolts and fastening screws in the host shall be tightened with force. (3) Check whether the tightness of each transmission belt is appropriate, rotate the motor pulley of the host by hand, the host should rotate flexibly, and open the door to check whether the grinding roller rotates flexibly. (4) Check whether the handle of the regulating valve of the air inlet pipe of the blower is in the “off” position. (5) . check whether the tightness of the hoist chain is appropriate. (6) Add oil and lubrication to each oil filling point according to the provisions of the oil filling and lubrication table, and check whether there is oil leakage everywhere. (7) Adjust the size of the discharge port of the jaw crusher according to the material properties, and the maximum size shall not exceed 20mm. (8) Check whether the rotation of each motor is correct: (a) the rotation direction of the main engine motor shall ensure that the central axis of the main engine rotates clockwise from top to bottom. (b) The rotation direction of the analyzer motor shall ensure that the rotation direction of the blade rotary table is clockwise, which is clockwise from the shaft end of the analyzer pulley (not the speed regulating motor pulley), (c) the direction of the blower: counterclockwise from the blower pulley end (9) Check the electric control cabinet: due to the shaking during transportation, the manufacturer is afraid of damaging the contact of the current relay, so it is bound with a white wire before leaving the factory. The white wire must be loosened before starting up, otherwise the change-over switch cannot play “automatic”.
