ZGT Series High Gradient Magnetic Separator

The ZGT Series High Gradient Magnetic Separator is designed for separation tasks where conventional magnetic equipment may be limited by low mineral magnetism or fine particle behavior. It is commonly applied in mineral processing plants to recover weakly magnetic ores such as hematite, manganese ore, ilmenite, wolframite, and tantalum-niobium ores, and it is also used for de-ironing and purification of non-metallic materials including quartz, feldspar, nepheline, fluorite, sillimanite, spodumene, and kaolin.

Separation is achieved by applying a high-gradient magnetic field while slurry moves through the separator under the combined effects of magnetic force, pulsating fluid force, and gravity. The pulsating slurry action helps keep particles dispersed during processing, supporting cleaner magnetic concentrate separation and reducing the tendency for the magnetic medium to become blocked during continuous operation.

The vertically rotating ring and reverse concentrate washing are intended to maintain stable performance over long runs by limiting buildup in the magnetic medium. This supports consistent separation results and helps reduce the frequency of shutdowns for cleaning, especially in applications with higher fines content.

The separator supports a broad separation size range with a maximum separation size of 2.0 mm, which can reduce the need for tight upstream classification in some circuits. For fine separation work, the best separation fineness is listed as minus 0.074 mm (200 mesh) accounting for 60–100%, or minus 2 mm depending on the material and separation objective.

The technical data below lists available ZGT models with feeding size limits, slurry concentration ranges, throughput capacity, installed power, and weight. If you share your ore type, target cut size, feed solids percentage, and required throughput, Bros Dirt Diggers can help align model selection with your circuit design and performance goals.

The table below shows ZGT Series model capacity ranges and requirements. Use max feeding size and feeding concentration to confirm feed suitability; use slurry passing-through capacity and ore capacity to estimate throughput; and use power and weight for utility and layout planning.

Note: The magnetic strength should be determined in accordance with the nature of the ore. ZGT Series High Gradient Magnetic Separators can be customer-made.
