Frequently Asked Questions
Q: What is the actual delivery time for the 250300 TPH assembly plant?
A: Standard manufacturing lead time is 4560 days from order confirmation. Preassembled modules reduce onsite installation to 57 days. Total project timeline from order to production: 6075 days.
Q: Can this plant handle materials with high moisture content (above 10%)?
A: The standard configuration is optimized for materials below 8% moisture. For higher moisture content, we recommend adding a vibrating grizzly feeder with 50mm spacing and a wet screening system. This modification adds $25,000$35,000 to the total cost.
Q: What is the expected lifespan of major wear components?
A: Based on field data from 200+ installations: jaw crusher liners (8,00012,000 hours), cone crusher liners (4,0006,000 hours), VSI wear parts (2,0003,000 hours), screen meshes (1,5002,500 hours). Actual lifespan depends on material abrasiveness and operating conditions.
Q: How does the assembly plant compare to a traditional fixed installation in terms of total cost?
A: Total installed cost is typically 1520% lower for the assembly plant due to reduced civil works (30% less concrete), faster installation (60% less labor), and standardized components. Total project cost including foundation: $1.1$1.4 million versus $1.4$1.8 million for traditional design.
Q: What electrical infrastructure is required onsite?
A: Minimum 630 kVA transformer capacity, 415V/50Hz or 480V/60Hz threephase power. The plant includes all motor control centers and distribution panels. Site must provide main power disconnect within 50 meters of plant location.
Q: Can the plant be expanded to higher capacity in the future?
A: Yes. The modular design allows for capacity upgrades to 350400 TPH by adding a secondary cone crusher and increasing conveyor speeds. Expansion cost is typically 3040% of original plant cost. Engineering modifications require 23 weeks.
Q: What training do you provide for plant operators?
A: Standard commissioning includes 3 days of handson training covering: startup/shutdown procedures, crusher gap adjustment, screen mesh replacement, PLC operation, and troubleshooting common issues. Advanced training (2 additional days) covers preventive maintenance scheduling and wear optimization.
