Time Required for Different Types of Maintenance
Daily Maintenance: Basic tasks such as cleaning, inspection, and tightening are performed before and after daily production; this takes approximately 30–60 minutesper session and does not significantly disrupt production time.
Weekly Maintenance: Tasks include conveyor belt adjustment, filter cleaning, and basic lubrication; this takes about 2–4 hours and can be scheduled during non-production periods.
Monthly Maintenance: Includes inspecting core components for wear, calibrating metering systems, and topping up or replacing oils; this takes about 4–8 hours, typically requiring half a workday.
Annual Comprehensive Maintenance: Involves complete equipment disassembly and overhaul, replacement of worn seals and bearings, and flaw detection on critical structural components; the entire process takes approximately 1–3 days, requiring a scheduled production shutdown.
Key Factors Affecting Maintenance Time
Equipment Scale: Annual maintenance for large commercial concrete plants (HZS120 model and above) takes about 50% longer than for smaller project-specific plants.
Operating Conditions: Plants subject to long-term high-load operation or significant material buildup require about 30% more time for cleaning and overhaul compared to plants in good operating condition.
Maintenance Team: Skilled original-manufacturer maintenance teams operate more efficiently, potentially reducing maintenance time by around 20% compared to non-specialized teams.
