(Summary description)The correct operation of the mill must first adjust the roll pitch and maintain the balance of the roll pitch. If the adjustment of the roller pitch at both ends is different, it will cause the rollers to be unbalanced and easily damage the equipment. This is strictly prohibited. After the work is finished, cut off the power supply and close the water and steam valves.

The correct operation of the mill must first adjust the roll pitch and maintain the balance of the roll pitch. If the adjustment of the roller pitch at both ends is different, it will cause the rollers to be unbalanced and easily damage the equipment. This is strictly prohibited. After the work is finished, cut off the power supply and close the water and steam valves.
 
For safety, we should abide by the following rules before starting up:
 
1. Before opening the mill, you must check whether the circuit (current and voltage, etc.), oil circuit (reducer, bearing, etc.), water circuit, etc. are normal! Then wear leather wrist guards (work with gloves is strictly prohibited), wear a kou cover for mixing operations, be sure to avoid waist ties, belts, rubber, etc., and don't wear clothes. Check carefully whether there is any debris between the large and small gears and rollers. When driving every shift, the emergency brake device must be tested to check whether the brake is sensitive and reliable (if it is a knee-impact device, you must be accustomed to touching your knee to the brake device). It is strictly forbidden to use the emergency brake device to shut down the car during normal operation. When the mixer is operated by two or more people, they must respond to each other and confirm that there is no danger before driving.
 
2. The temperature rise speed must be controlled when the roller is warmed up, especially in the cold winter in the north, the outside of the roller is consistent with the room temperature, and high temperature steam is suddenly introduced into the roller. The temperature difference between the inside and the outside may be above 120 ℃, and the temperature difference will cause the roller stress. It can reach 130.0~~I50.OMPa, which has exceeded U.1=140.OMPa of cast iron. If the rubber material is added too early, the roller can be easily damaged under the superimposed action of the transverse pressure. For the sake of safety, the empty car should be preheated, and the empty car should be refueled and lubricated at the same time, and the material should be fed when the temperature is raised to or close to the set temperature. This needs to be emphasized to the operator.
 
3. The rubber material should also be checked before the feed of the mixer. If there are hard metal debris, put it into the rubber mixer with the rubber, causing the horizontal pressure to suddenly increase, which will cause equipment damage.
