Magnetic Separation | SpringerLink

A dry high-intensity magnetic separator is a waterless separation machine introduced to separate weakly magnetic particles that DLIMS cannot process. This technology employs a greater magnetic field strength provided by an induced or permanent magnet to separate the materials based on their magnetic susceptibility [ 21, 22 ].

Methods of Separation

The grain is then separated from the stalks and grounded into the floor by beating the dry stalks to shake off the dried grains. Winnowing. ... Magnetic separation is the process of separating components of mixtures by using magnets to attract magnetic materials. The process that is used for magnetic separation detaches non-magnetic material ...

Choosing Process and Separation Seals | Pumps & Systems

Process and separation seals (Figure 1) help create an ideal environment that ensures favorable dry gas seal operation. Using the correct type of seal offers the benefits of increased reliable dry gas seal operation, reduced utility costs, reduced recycling of compressed gas and increased safety. These seals create a restriction between ...

Dry vs Wet Separation Methods in Mineral Processing

For example, dry separation methods are more suitable for fine and dry materials, while wet separation methods are more suitable for coarse and wet materials. Similarly, some minerals may respond ...

Electrostatic Separation | SpringerLink

The electrostatic separation technique is generally utilized for recycling metallic materials from electronic waste [1,2,3,4,5,6].This dry separation technology is also successfully employed in mineral processing [7,8,9,10] and the food industry [11, 12].As a perfectly dry method, electrostatic separation is an environmentally friendly technique …

Ultrahigh loading dry-process for solvent-free lithium-ion …

The current lithium-ion battery (LIB) electrode fabrication process relies heavily on the wet coating process, which uses the environmentally harmful and toxic N-methyl-2-pyrrolidone (NMP) solvent.

Dry fractionation methods for plant protein, starch and fiber

The combined wet/dry separation required 15 kg water/kg protein isolate, whereas aqueous separation alone required 85 kg water/kg protein isolate. Likewise, the energy consumed by drying the product was far lower for the combined procedure (11 MJ/kg) compared to the conventional wet process (63 MJ/kg isolate).

A two-step air classification and electrostatic separation process …

With the optimized dry fractionation process, a protein-enriched fraction with a yield of 4.0 g/100 g pea was obtained, leading to 7.8% of total protein recovered from yellow pea (Table 2). The mass balance for the entire dry fractionation process is visualized in a Sankey diagram (Fig. 10). The yield in protein reported in this study may …
