DELKOR reported the MAX-FeED iron ore belt feeder can increase throughput without compromising on filter cake moisture requirements and with no additional equipment required. The feeder design is optimized for the process flow pattern with maximized slurry distribution across the width of the belt.
The adjustable weir system provides a wider operational flow range and better handling of flow conditions. It prevents fluctuation or surging of slurry flow.
The adjustable spigot nozzle and distribution screens are designed to handle larger throughput and scalability. The resulting throughput is greater than that of conventional feeders, DELKOR said.
The front and rear sloped feeding system provides optimal feeder performance at high throughput rates.
Recent field results show that, at a major iron ore site in Australia, the belt feeder reduced the number or size of filters. That resulted in lower capital, transportation, installation and operating costs; as well as a reduction in necessary spares, overall maintenance and equipment footprint.
Further, the throughput increased from 300 to 500 m3/h, and cake thickness was reduced from more than 10 to less than 5 mm. Moisture content remained constant over the entire width of the belt and the filter cake was dewatered at the edges to the same extent as the rest of the cake.
The belt feeder helped attain a minimum filtration rate of 3,500 kg/m2/h and a cake moisture target of 12% and below.
