Reduce friction and minimize wear
Cooling, prevent bearing overheating
Clean the system and prevent contaminants from entering
Corrosion protection, extend the lifespan of components
Bearings are the core wear-prone components of crushers
Poor lubrication is the main cause of high failure rates in jaw crushers, cone crushers, and impact crushers
Proper lubrication can extend equipment lifespan by more than 30%
Type
Features
Applicable Equipment
Grease lubrication
Simple and easy to operate, but requires regular replacement
Small jaw crushers, impact crushers
Oil circulation lubrication
Constant oil temperature, automatic circulation, good heat dissipation
Medium and large jaw crushers, cone crushers, multi-cylinder hydraulic cone crushers
Oil-water mixed cooling
Used in high-temperature environments, reduces bearing temperature
High-capacity crushers, continuous operation equipment
Truth:
Many manufacturers recommend “multi-purpose lubricating oil,” but not replacing the filter = equivalent to wasting the oil
Grease lubrication is suitable for small equipment, but high output and high-hardness materials must use an oil circulation system
Small crushers → 40#–50# lithium-based grease
Medium and large crushers → mineral oil or synthetic oil (ISO VG32–46)
High-temperature environment → high-temperature-resistant lubricating oil
Dusty environment → high-viscosity oil to reduce wear
Grease: replace once every 500–1000 hours
Oil circulation system: replace every 3000 hours or according to oil quality testing
Observe oil temperature, oil level, and whether pipelines are leaking
Check bearing vibration and noise
Replace lubricating oil/grease
Clean oil tank and filter
Check oil pump, pipelines, and joints
Abnormal bearing temperature → insufficient oil quantity or degraded oil quality
Increased noise → insufficient lubrication or contaminant intrusion
Leakage → aging pipelines or loose joints
Misconception 1: The more oil added, the better
Actual: Excess will cause heating and contaminate bearings
Misconception 2: Only change oil without cleaning the filter
Filter blockage = poor oil circulation → high failure rate
Misconception 3: No cooling under high temperature
Lubricating oil temperature too high → viscosity decreases, protection fails
1️⃣ Select lubrication method and oil type according to the equipment manual
2️⃣ Establish a lubrication record sheet and operate according to shifts/cycles
3️⃣ Regularly test oil quality and bearing condition
4️⃣ Large production lines adopt automatic lubrication + oil temperature monitoring

The user purchased two sets of sand production line, each set of equipment includes ZSW490*110 vibrating feeder, PE750*1060 jaw crusher, HST250 single-cylinder cone crusher, JYS1238 sand making machine, YK2460 vibrating screen, 3016 sand washer and so on.
The designed capacity of this sand making project is 200t/h, and the equipment used includes 490*110 vibrating feeder, PE750*1060 jaw crusher, PF1315 impact crusher, 9928 sand making machine, two sets of 2460 vibrating screen, two sets of 920 single screw sand washer, two sets of XSD2816 sand washer, two sets of dewatering screen, and several belt conveyors.
Project configuration: Jaw Crusher PE900*1200, Cone Crusher HST315T, Vertical Shaft Impact Crusher VSI6X1263, Heavy Duty Vibrating Screen 2YKZ3080/3YKZ3080, Vibrating Feeder ZG1220Z/ZSW1360, Twin Screw Sand Washer 2XL1120, Bar Vibrating Feeder ZSW1360B, Bucket Wheel Sand Washing Machine DS4024, dewatering screen TS2450 many types of equipment. They will work together with the whole production line to crush and process the sand trap cobbles and mountain ores into natural sand, mechanism sand, and uniform material.
The finished products of the project are used for high-speed railway construction and neighbouring construction materials, which will strongly promote the local economic development. In the future, Jianye Heavy Industry Company will continue to give full play to its years of practical experience in the sand and gravel aggregate, construction waste resource reuse, industrial powder making, silica sand and other industries, as well as EPC one-stop turnkey services, to cooperate with customers and jointly promote the high-quality, healthy and sustainable development of the sand and gravel industry.
Jiangsu Rugao Calcium Powder Factory purchased two sets of Jianye 4121 high-pressure mills for the production of heavy calcium powder, which is mainly used in the filler industry and coating industry, and now it also maintains a close cooperation relationship with Jianye, and every year Jianye sends technicians or sales managers to visit the user.
The user uses calcined petroleum coke to grind and make powder, and the finished coke powder is mainly used for processing graphite electrodes. In recent years, the price of coke powder rises, the user spends tens of millions of dollars to build a production line with an annual output of 60,000-100,000 tonnes of high-quality coke powder, which is the first phase of the project, using two sets of 6R4528 high-pressure grinding mills of Jianye Company.
