Portable crusher plant integrates feeding, crushing, screening and conveying functions, widely used in quarry processing, mineral crushing and construction waste recycling projects. Scientific and standardized daily maintenance is essential to reduce breakdown risks, prolong equipment service life and guarantee continuous stable production. The portable crusher plant works under complex field conditions, so regular inspection and maintenance work cannot be ignored. As a professional portable crusher plant factory, Shanghai Dongmeng summarizes practical daily maintenance guidance for global project operators.

Daily inspection before startup

Before starting the whole set of equipment, walk around the unit for comprehensive visual check. Check chassis fastening, tire or track condition, and confirm no deformation or loose bolts. Inspect the wear‑resistant parts inside crushing host, clear residual stones and sundries in the crushing cavity. Check lubricating oil, hydraulic oil level and quality, confirm there is no oil leakage on pipelines and joints. Check tension of belts, protective covers and electrical system. Do not start the equipment with hidden faults.

Inspection items during operation

After startup, keep observing the running state of the whole unit. Pay attention to abnormal vibration, strange noise and sharp temperature rise of each component. Monitor material feeding and discharging situation, avoid material blockage caused by excessive feeding. Check the working condition of dust removal system. If any abnormal phenomenon occurs, stop feeding first and troubleshoot problems, never keep running with faults.

Post‑shift maintenance work

After finishing daily production, cut off feeding and wait for all materials inside equipment to be discharged completely before shutdown. Clean dust, mud and material accumulations on the surface of the whole portable crusher plant. Check wear status of blow bars, liners, screen mesh and other vulnerable components. Tighten loose bolts and connectors. Supplement lubricating grease for each lubrication point, and record equipment operation data and fault conditions.

Periodic scheduled maintenance

Besides daily checks, implement weekly and monthly maintenance plans. Replace deteriorated lubricating oil and hydraulic oil on schedule. Deeply inspect wear degree of key components such as rotor, bearing and transmission parts. Check chassis, walking system and hydraulic cylinder sealing performance. Replace severely worn spare parts in advance to prevent sudden shutdown failures. Strictly follow the technical manual for maintenance operation.

Matters needing attention for storage and site transfer

When the portable crusher plant needs to be transferred or stored for a long time, do well anti‑rust and dust‑proof treatment. Clean up residual materials, coat anti‑rust grease for exposed metal parts. Check walking system before moving, ensure road condition meets transportation requirements, avoid violent bumping during transfer which causes internal component damage.
