　　1、应仔细检查轴承的润滑情况是否良好，轴承内肘板连接处是否有足够的润滑脂。

　　2、应仔细检查所有的紧固件是否完全紧固。

　　3、防护装置是否良好，发现不安全现象，应立即消除之。

　　4、检查破碎腔内有无矿石或其他杂物，如有则应立即消除。

　　（二）颚式破碎机的起动

　　1、经检查、证明机器与传动部分情况正常，始可起动。

　　2、本机只能在无负荷情况下起动。

　　3、起动后，若发现有不正常的情况时，应立即停车，待查明原因排除隐患，方可再次起动。

　　（三）颚式破碎机的维护和使用

　　1、破碎机正常运转后，方可投料。

　　2、待破碎材料应均匀地加入破碎腔内，并应避免侧面加料，防止负荷突变或单边突增。

　　3、在正常工作情况下，轴承的温升不应超过35℃，很高温度不得超过70℃，否则应立即停车，查明原因加以消除。

　　4、停车前，应先停止加料，待破碎腔内被破碎物料完全排空后，方可关闭电机。

　　（四）颚式破碎机的润滑

　　1、经常注意及时做好磨擦面的润滑工作，可保证机器的正常运转和延长使用寿命。

　　2、本机采用的润滑脂，应根据使用地点、气温等条件来决定，一般可采用钙基、钠基或钙钠基润滑脂。

　　3、加入轴承座的润滑脂为其容积的50－70%，每三个月必须更换一次；换新油时必须用干净的或油清洗轴承与轴承座内污物。

　　4、肘板与肘板垫接触处在机器开动前，必须加入润滑脂。

　　Jaw crusher | Jaw crusher | Crusher price | Crusher manufacturerPE300x500

　　Advantages of jaw crusher: simple structure, low manufacturing cost, easy maintenance and repair, reliable operation, small machine height, easy configuration, and less likely to block ores with high moisture and high viscosity. Disadvantages: Low productivity, high electricity consumption, large vibration, small crushing ratio, uneven product particle size, and inability to fill the ore.

　　instructions

　　（1）Preparation work before starting the jaw crusher

　　1. Careful inspection should be conducted to ensure that the lubrication of the bearings is good and that there is sufficient grease at the elbow joint inside the bearings.

　　2. All fasteners should be carefully checked for complete tightness.

　　3. Whether the protective device is in good condition and any unsafe phenomena should be immediately eliminated.

　　4. Check if there are any ores or other debris in the crushing chamber, and eliminate them immediately if there are.

　　（2）Starting of jaw crusher

　　1. Only after inspection and verification that the machine and transmission parts are in normal condition can it be started.

　　2. This machine can only be started under no-load conditions.

　　3. After starting, if any abnormal situation is found, the vehicle should be stopped immediately and the cause should be identified and hidden dangers eliminated before starting again.

　　（3）Maintenance and use of jaw crusher

　　1. The crusher can only be fed after normal operation.

　　2. The material to be crushed should be evenly added into the crushing chamber, and side feeding should be avoided to prevent sudden load changes or unilateral increases.

　　3. Under normal working conditions, the temperature rise of the bearing should not exceed 35℃, and the maximum temperature should not exceed 70℃. Otherwise, the vehicle should be stopped immediately, and the cause should be identified and eliminated.

　　4. Before parking, the feeding should be stopped first, and the motor can only be turned off after the crushed material in the crushing chamber is completely emptied.

　　（4）Lubrication of jaw crusher

　　1. Regularly paying attention to timely lubricating the friction surface can ensure the normal operation of the machine and extend its service life.

　　2. The lubricating grease used in this machine should be determined according to the usage location, temperature, and other conditions. Generally, calcium based, sodium based, or calcium sodium based lubricating grease can be used.

　　3. The lubricating grease added to the bearing seat is 50-70% of its volume and must be replaced every three months; When changing the oil, clean gasoline or kerosene must be used to clean the dirt inside the bearings and bearing seats.

　　4. Before starting the machine, lubricating grease must be added to the contact area between the elbowa plate and the elbow pad.
