Chile has rich basalt resources, and 400TPH basalt crushing production lines are widely used in local highway and airport construction. However, traditional production lines have high energy consumption, which increases the operation cost of enterprises. A 400TPH basalt crushing line in Chile has achieved significant energy-saving effect after renovation.
### Original Production Line Problems
The original production line adopted a "primary crushing + secondary crushing + tertiary shaping" process, with the following problems: traditional high-energy-consuming crushers, high unit energy consumption (2.2kWh/t); unreasonable process layout, long material transportation distance, high energy consumption of belt conveyors; no frequency conversion device, high no-load energy consumption; insufficient dust removal equipment, failing to meet environmental protection standards.
### Renovation Plan
1. Equipment Renovation: Replace the traditional jaw crusher and cone crusher with high-efficiency energy-saving models, reducing unit energy consumption by 25%; install frequency conversion devices on all motors, adjusting the motor speed according to production load, reducing no-load energy consumption by 30%.
2. Process Optimization: Adjust the process layout, shorten the material transportation distance by 40%, replace the traditional belt conveyor with energy-saving belt conveyors, reducing transportation energy consumption by 20%; optimize the crushing ratio, reduce the number of repeated crushing, further reducing energy consumption.
3. Environmental Protection Upgrade: Add 25 sets of pulse dust collectors, upgrade the fully enclosed workshop, ensuring the dust emission concentration is ≤8mg/m³, meeting Chile's strict environmental protection standards.
4. Intelligent Monitoring: Equip the production line with an intelligent monitoring system, real-time monitoring of energy consumption of each equipment, finding and solving energy-consuming problems in time.
### Renovation Effect
After renovation, the unit energy consumption of the production line was reduced from 2.2kWh/t to 1.3kWh/t, saving 1.8 million kWh of electricity annually, reducing the operation cost by 220,000 US dollars. The production efficiency increased by 15%, and the failure rate decreased by 40%. The production line not only achieved energy saving and emission reduction but also improved economic benefits.
