How to Maintain the Sand Making Machine?

High-frequency operation prevails in global sand aggregate processing, mining aggregate and construction waste recycling industries. Standardized maintenance can greatly extend equipment service life and stabilize production capacity. sand making machine serves as the core host for shaping and sand production of the entire sand production line, and its maintenance directly affects production stability, processing costs and finished aggregate quality of processing plants. Working conditions vary greatly across countries. Environments with heavy dust, high humidity, heavy rainfall, strong wind and low temperature will accelerate wear of consumable parts, aging of oil circuits and damage of circuits of sand making machines. For producers worldwide, a standardized maintenance plan adaptable to multiple scenarios is essential to guarantee long-term stable operation of sand making machines. There are various types of sand making machines on the market, including vertical impact sand making machines, mobile sand making machines and compound sand making machines. Their maintenance priorities differ, so classified maintenance plans need to be formulated according to equipment structures and operating environments.

1. Daily Basic Inspection and Maintenance

Three-level inspections before startup, during operation and after shutdown constitute the most fundamental maintenance work of sand making machines. Before starting the machine, check whether the feeding inlet and discharging outlet are blocked by accumulated materials, measure the wear loss of vulnerable parts such as impellers, impact blocks and lining plates, and confirm all anchor bolts and fasteners are tightly fixed. During operation, monitor equipment vibration, abnormal noise, oil temperature and current values, and shut down the machine for troubleshooting once abnormalities occur. After daily work, clean accumulated materials inside the machine cavity and dredge dust removal pipelines to avoid corrosion of the machine body caused by caked sand and stone. For overseas operating sites with heavy dust, heat dissipation air ducts must be cleaned regularly to prevent motor burnout caused by overheating. Lubricating oil is vital for maintenance. Grease and hydraulic oil of specified models must be used. Oil change cycles should be shortened in high-temperature regions, and anti-freeze oil should be adopted in low-temperature areas to guarantee smooth operation of transmission components.

2. Regular In-depth Periodic Maintenance

Carry out weekly, monthly, quarterly and annual major maintenance according to total running hours. Fasten all connecting components and check belt tightness every week. Disassemble and inspect impeller assemblies and calibrate rotor dynamic balance monthly to prevent violent vibration caused by uneven wear. Inspect bearing clearances and aging of sealing parts quarterly, replace aged oil seals to stop oil leakage and dust ingress. Conduct full disassembly and overhaul once a year to check cracks on racks and welding joints and calibrate all assembly dimensions. Additional maintenance of walking chassis, tires and hydraulic outriggers is required for mobile sand making machines to adapt to frequent site transfer of overseas projects. Many overseas customers suffer premature major maintenance and high consumption costs due to lack of professional maintenance standards.

3. Targeted Maintenance and Replacement Management of Vulnerable Parts

Impellers, throwing heads, wear-resistant lining plates and impact blocks are the most consumable accessories of sand making machines. Higher hardness of sand and stone leads to faster wear. Inspection frequency shall be increased when processing hard materials such as granite and basalt, while maintenance intervals can be appropriately prolonged for soft raw materials like limestone. Overseas clients are advised to stock original wear-resistant spare parts instead of non-standard accessories. Mismatched non-standard parts easily cause rotor imbalance and machine body cracking. Reliable supply channels and original accessory support help cross-border enterprises conduct convenient maintenance, so most overseas purchasers attach great importance to qualified sand making machine manufacturer during selection.

High-quality Sand Making Machine Manufacturer Provides Full-process Support for Maintenance

Smooth implementation of comprehensive maintenance plans relies on technical backing. Professional sand making machine manufacturers supply not only equipment, but also full-lifecycle maintenance guidance. Most small and medium-sized manufacturers only provide simple operation manuals without multilingual maintenance documents and remote technical support, making it hard for overseas users to resolve faults quickly. Manufacturers with global service capabilities can customize maintenance schemes matching local climate and raw material characteristics and build local spare parts warehouses to reduce difficulties of cross-border maintenance. Shanghai Dongmeng has focused on R&D and manufacturing of crushing and sand making equipment for years. As a reputable professional sand making machine manufacturer worldwide, it delivers reliable equipment and global maintenance services to meet maintenance demands of clients in Asia, Europe, Africa, Southeast Asia and other regions.

4. Exclusive Maintenance Service Advantages of Shanghai Dongmeng

All sand making machines manufactured by Shanghai Dongmeng are equipped with detailed multilingual maintenance manuals, which list clear maintenance steps for fixed and mobile DVSI sand making machines, as well as oil change cycles and vulnerable part replacement cycles corresponding to different temperatures and raw materials. The equipment features humanized maintenance structures. The hydraulic opening design enables convenient inspection inside the machine cavity without complicated disassembly, lowering maintenance difficulty for overseas workers. The enterprise has a global online technical team offering remote video guidance for disassembly, accessory replacement and fault diagnosis. Besides, Shanghai Dongmeng builds a global spare parts warehousing network to enable overseas customers to obtain original wear-resistant accessories rapidly without long waiting for cross-border logistics. For large overseas production lines, professional engineers can travel onsite to deliver maintenance training so local staff can independently complete all maintenance and repair procedures.

5. Key Tips to Avoid Maintenance Mistakes

Many enterprises make common maintenance errors, including continuous operation with insufficient lubrication, running equipment with hidden faults, mixing lubricating oil of different grades and applying inferior wear-resistant parts. These errors often result in severe failures such as bearing seizure, rotor fracture and machine shell damage, bringing higher shutdown losses than maintenance costs. All domestic and overseas projects should adhere to scheduled maintenance, use original spare parts and follow official maintenance specifications to control long-term operating costs. Choosing established sand making machine manufacturers like Shanghai Dongmeng allows users to obtain durable sand making machines, complete maintenance guidelines, stable accessory supply and global after-sales support. It helps sand processing plants worldwide implement standardized equipment maintenance, cut downtime losses and raise long-term production benefits.
