Complex mineralogy and energy consumption force iron ore producers to seek better dewatering solutions for optimal pelletizing feed.
Many key parameters need to be addressed during the filtration process, with filter cake moisture stability being critical. At initial levels of 30 to 50%, surplus water needs to be removed prior to the balling process, targeting a moisture content from 8 to 10% for most plants.
The challenge is to obtain a consistent filter cake moisture content while achieving high throughput.
AVOID INTERNAL COMPONENT WEAR AND REDUCE VACUUM LOSSES
M7 equipment optimizes filtering capacity by providing steady throughput with minimal downtime. This results in a significant in up to 45% increase in tonnage, as demonstrated in retrofit projects without increasing vacuum requirements, and lower energy consumption in downstream processes.
Its distinctive mechanical design and the use of proprietary surface coating technologies on critical components provide industry-leading sealing and durability. Leakages are minimized, maintenance frequency is reduced, and stable performance at low operating costs is achieved.
We offer an automatic scraping system for safe cleaning of filter cake chutes, without operator intervention.
We can run tests in our in-house laboratory to analyse end-users’ slurry to optimize and confirm system’s performance.
In addition to manufacturing the most efficient vacuum disc filters in the industry, we also provide replacement parts and performance upgrades. Our valve and wear plates are manufactured with M7 specialty coating technology and UHMW to avoid wear and resulting vacuum losses and extended downtime.
