A classifier equipment with overflow end spiral completely submerged below the liquid surface.
Xinhai tailings dry stacking technology is mainly applied to the dewatering and concentrating of mineral tailings in the mineral processing plants. To reach the aim of tailings dry stacking and avoiding environmental pollution, it is the essential technology of green mine.
Phosphate Flotation Product Line is applied for complex structure phosphate with fine particle distribution, closed embeddedness relationship, difficult monomer dissociation, etc.
Barite is fragile and like a big tube. The separation methods of Xinhai are generally gravity separation, magnetic separation and flotation.
Alluvial gold processing solution mainly applies to processing alluvial gold with a large volume of gangue minerals. Alluvial gold processing is a set of mining processes, including crushing and screening, desliming stage, separating stage, etc.
Grinding force is provided via hydraulic pumping system and assisted by nitrocharged accumulators. The roller press is designed to operate in choke feed conditions. Feed material is introduced into the gap between the rolls. This action starts to push the moveable roll against the hydraulic rams compressing the nitrogen in the accumulators.
This movement of the floating roll constitutes the basic principle of highpressure comminution with a roll press. The extent of the roll movement (roll gap) is a function of the pressing force generated by the hydraulic system in relation to the reaction forces exerted by the processed material.
With our Roller Presses the grinding pressure is transferred from the hydraulic system via the movable roll to the material bed and absorbed in a stable closed machine frame. A key feature is the mounting of the rollers in oillubricated cylindrical roller bearings. The oil is both lubricant and cooling agent.
Press is available in ten standard sizes ranging in grinding force from 2 to 32 meganewtons. The specific grinding pressure is kept below 7.0 N/mm 2 in order to limit the stress on the rollers (grinding pressure = grinding force/roll diameter/roll width). The pressure between the rolls can be lower for grinding granulated slag raw
