V. Frequently Asked Questions (FAQ)
Q1: What preparations are needed for relocation?
A1: Emptying materials, sealing interfaces, tightening components, checking the walking system, and planning the route. This can be completed by 2-3 people in one day.
Q2: How is asphalt performance ensured in low-temperature environments?
A2: The normal operating temperature range for the equipment is -10℃ to 40℃. In low-temperature environments (below 0℃), the following technical measures can be used to ensure asphalt performance:
① The asphalt tank and conveying pipelines are equipped with double insulation (heat transfer oil heating + electric tracing), and real-time temperature monitoring is implemented;
② Enhanced insulation measures are applied to the finished product silo, and auxiliary heating devices are activated when necessary;
③ Mixing process parameters are optimized, and the mixing time is appropriately extended by 5-10 seconds to ensure uniform material mixing;
④ Before starting the equipment, all pipelines and the mixing tank are preheated to prevent asphalt from solidifying upon contact with low-temperature components.
Q3: Can the equipment’s production capacity be adjusted according to project requirements? How is the quality stability of different mixed materials ensured?
A3: The equipment’s production capacity can be flexibly adjusted through the control system. The specific production rate can be set within the rated capacity range (80-240 t/h) according to the type of mixture and project progress requirements. The core technical measures to ensure the stable quality of different mixture formulations are as follows:
① The control system supports the storage of over 100 recipes, eliminating the need for recalibration during recipe switching; recipes can be directly recalled and used;
② The high-precision weighing system integrates dynamic compensation functionality to correct measurement errors in real time;
③ The mixing blades are optimized using fluid dynamics principles to ensure thorough mixing of materials with different particle sizes;
④ Key parameters such as mixture temperature and weight are monitored in real time during production, and the system automatically triggers alarms and implements corrective measures if parameters are abnormal.
Q4: Does it meet environmental standards? Can it be modified?
A4: It complies with GB 40850-2021 standards and can be adapted to higher requirements by upgrading dust removal and adding desulfurization and denitrification devices.
