Disk Filters

 

Disk filters are used with vacuum filtration equipment. They are made of several large discs, up to 15 in larger machines. Each disk consists of sectors that are clamped together. The ribs between the sectors lead radially towards the neck, which is at the center of the disk. The filter is fed from the side.  A cake forms on the face of the disc as it rotates and the enters a drying zone where the filtrate drains to the center barrel and then through a valve to the vacuum receiver. Scraper blades on the side of each disc remove the cake to discharge chutes. Generally, disk filters are used for heavy duty applications such as dewatering of iron-ore taconite, coal, aluminum hydrate, copper concentrate, and other beneficiation processes.

Products & Services
Rupture Discs and Burst Discs
Rupture discs and burst discs are designed to open and relieve overpressure, high temperature, or vacuum conditions at a predetermined differential pressure or specific temperature. They may be thermally or mechanically actuated.
Abrasive Discs
Abrasive discs consist of abrasive grain adhered onto the surface of a cloth, film, paper, non-woven or other backing. They are used for metal removal, surface finishing, sanding, etc.
Dewatering Equipment
Dewatering equipment uses force, including vacuum and centrifugal motion, to separate water from solids.
Ball Transfer Units (BTU)
Ball transfer units (BTU) are ball transfer table components that consist of a large, load-bearing ball that sits atop smaller balls inside of a hemispherical cup.
