Iron Ore Slurry Dewatering Solutions

Vacuum Disc Filter

A solution to optimize filtering capacity by providing steady throughput with minimal downtime.

M7 equipment optimizes filtering capacity by providing steady throughput with minimal downtime. This results in up to 45% increase in tonnage, as demonstrated in retrofit projects without increasing vacuum requirements, and lower energy consumption in downstream processes.

The Challenge

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 efficiency of the filtration process significantly impacts all subsequent operations.

The challenge is to obtain a consistent filter cake moisture content while achieving high throughput.

The Solution

AVOID INTERNAL COMPONENT WEAR AND REDUCE VACUUM LOSSES

M7 Vacuum Disc Filter’s distinctive mechanical design and the use of proprietary surface coating technologies on critical components provide industry-leading sealing and durability, extending the life of key components and enhancing the abrasion resistance, and thus the long term sealing of the filter.

Leakages are minimized, maintenance frequency is reduced, and stable performance at low operating costs is achieved.

SPECIALTY COATING TECHNOLOGY

Since 1978, we are renowned for our surface coating expertise.

Our valve head and wear plates are manufactured with M7 specialty coating technology and UHMW to avoid wear and resulting vacuum losses and extended downtime.

KEY TECHNICAL SPECIFICATIONS

Not all vacuum filters are created equal.

Lots of suppliers of vacuum disc filters are active on the market, but very few could combine reasonable tonnage per hour, energy efficiency, adequate and consistent moisture and low maintenance. Even fewer could maintain their performance after even few weeks of operation.
