Choice of Excavator
The choice of excavator is a complicated process, which is mainly determined according to the conditions of mining and stripping quantity, physical and mechanical properties of ore rocks, mining technology and equipment performance, so as to give full play to the efficiency of mine production equipment. The production equipment of each process should be mutually adapted and matched reasonably. Whether to choose the electric shovel or hydraulic shovel excavator must be carefully considered. Wh...
Choice of Loading Equipment
When loading equipment is used as auxiliary equipment in open pit mine, it is necessary not only to consider whether the main technical performance, such as rated load and traction force, can meet the requirements of complexity of mine production, but also to consider the influence of the scattered operation items on the efficiency of loader. When you have requirements for ore blending, you should first set up a storage yard near the crushing station, and the transportation of the prepared or...
Transportation accounts for 40% to 60% of the total cost of open pit mining, so the choice of transportation equipment is very important. The choice of transportation equipment for open pit stopes mainly depends on the development and transport mode. When the transportation distance of ore rock is short, the single vehicle transportation should be considered first. When the distance of ore and rock transportation is long, it is necessary to determine whether to use single vehicle transportation or joint development transportation through technical and economic comparison. The main factors that affect the choice of development transportation methods are the natural geological conditions, mining technical conditions, and economic factors. When using automobile transportation, it is necessary to consider its compatibility with the excavator. It is generally believed that when the haul distance is 1km, the automobile with 2 to 4 buckets should be used. When the haul distance is 2km, the...
Drilling rig is a kind of equipment that is easily overlooked, because it occupies a small proportion of production cost. But drilling rigs are the open pit mining equipment that is the easiest to realize automation. Roller bit hole rig is suitable for drilling operations of various hardness rocks. The first choice for drilling equipment in large and medium sized mines is roller bit hole rig. For small and medium sized mines with medium hard rock and some special requirements, such as slope holes, anchor cable holes, and drain holes, it is more appropriate to use down the hole drills.
The choice of auxiliary equipment is mainly based on the production equipment. When the main equipment is large, the size of the auxiliary equipment should be increased accordingly. Crawler bulldozers support loading and transporting equipment by leveling explosive piles, clearing topsoil, road construction, and occasionally trimming slopes. For hard rock mines, the use time of the bulldozer is required to be 20% to 30% of the use time of the excavator. Usually when the load capacity of dump truck is more than 100T, you should choose the crawler bulldozer with power greater than 380kW. The grader should be selected according to the length of the transportation road and the driving density. For mines with long haul roads and high traffic density, you should consider choosing a grader with high power. Generally large mines should choose graders with the power greater than 198kW. The main reason why wheel bulldozers can be used as auxiliary equipment is their high maneuverability and t...
Open pit mining equipment is steadily developing in the direction of large scale, automated, intelligent, and informationalized. Reasonable choice of open pit mining equipment can effectively reduce mining costs and strive for greater benefits. If you want to purchase mining equipment, or want to know more information about equipment choice, please submit a message or consult online customer service, we will reply you as soon as possible.

Excavators are common equipment in mining operations. Once a failure occurs, the progress of the project will be delayed. Repair and maintenance are technical activities implemented to improve equipment performance, which improves labor productivity and the ability to avoid production accidents. The quality of repair and maintenance directly affects whether the mining excavator can work normally and efficiently. During the operation of the mining excavator, improper operation or excessive operation will cause the parts of the excavator to be worn out, which greatly reduces the safety of the excavator, resulting in a continuous decline in the performance of the excavator and gradually reducing its work efficiency. If the fault is not repaired in time, some parts of the excavator will be damaged and the equipment stops working or will cause an explosion, threatening peoples lives and property if the case is serious. Therefore, mining enterprises must establish a sound equipment manag...
Reduced Excavator Work Efficiency
（1）Failure Cause The reduced efficiency of the mining excavator is due to severe abrasion on the internal components of the excavator. When the excavator is working for a certain period of time, the internal parts of the excavator hydraulic pump will wear out. Once the abrasion is excessive, the internal leakage of the hydraulic system will result in insufficient flow in the hydraulic pump and excessive oil temperature, which greatly reduces the speed of the excavator. （2）Inspection and Repai...
Lifting Failure of Rocker of Excavator
（1）Failure Cause The failure of the rocker mainly affects the automatic lifting and operating lifting. If the rocker arm suddenly fails to lift normally during the working process of the mining excavator, it may be that the remote control, the signal receiving end of the equipment or the microcomputer control end has malfunctioned, which will cause the rocker cannot work normally. （2）Inspection and Repair 1. If the rocker malfunctions because of a problem with the remote control, it can be so...
Excavator Motor Heating Failure
（1）Failure Cause A cooling device is usually installed inside the excavator, so the temperature of the excavator motor is generally not too high. If the temperature of the excavator is too high, it is likely that there is a problem with the cooling device, such as insufficient water in the cooling water pipe or blockage of the water pipe that prevent cooling water from entering the working position can cause the motor to heat up. （2）Inspection and Repair If the motor heats up, it may be that...
The purpose of maintenance work for mining excavators is to maintain normal wear of the equipment and avoid accidental wear. Maintenance work should be an important part of production throughout the daily production work. The maintenance work of the excavator includes three specific contents: inspection, cleaning, and lubrication.
With the rapid development of the mining excavatorindustry and the improvement of excavator manufacturing level, the requirements for the maintenance and management of excavators are getting higher and higher. Affected by the operating environment and human factors, excavators are prone to failure. It is recommended that all mine owners do a good job in the maintenance of excavators, so as to reduce the occurrence of excavator failures, improve the efficiency and safety of excavators, and provide a strong guarantee for the smooth progress of efficient production of enterprises. The above introduced the reasons for the failure of the mining excavator and the maintenance methods. Does your current excavator equipment have the above problems? If so, find the answer from the above methods! If you have other questions about the repair and maintenance of mining excavators, you can consult the online customer service and leave a message, we will contact you as soon as possible!
