Currently, fertilizer companies are focusing on controlling production costs. Through proper optimization, coating machines can achieve energy savings and consumption reduction, helping companies lower operating costs.
First, energy saving in the heating system. Some coating machines utilize a waste heat recovery design. A heat exchanger is installed at the heat sealing channel outlet to collect the exhaust hot air and preheat the incoming cold air, reducing heat consumption in the heating tubes. This design reduces heating energy consumption and is particularly suitable for companies with continuous production, with significant energy savings over the long term. Furthermore, variable frequency heating tubes are used, which automatically adjust power based on particle flow rate. For example, when production capacity drops to 50%, heating power is also reduced, avoiding high-temperature operation and wasting energy during idle periods.
Second, motor frequency conversion modification. The equipment’s conveyor belts, film reels, and other motors utilize variable frequency control. During production, the PLC system is linked to a particle flow sensor to automatically adjust motor speed based on particle flow rate. Compared to traditional fixed-speed motors, variable-frequency motors can save 10%-12% of electricity, operate more smoothly, and reduce noise by 5-10 decibels, improving the workshop working environment.
Third, film utilization is improved. Some coating machines support adaptive film width adjustment. When changing films of different widths, manual adjustment of the film guide mechanism is eliminated, and the optimal wrapping width is automatically matched. This reduces material loss during the commissioning process. Long-term use can significantly reduce raw material procurement costs, supporting enterprises in reducing costs and increasing efficiency.
