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.

Introduction. Silica has recently been in the news because this past August the US Occupational Safety and Health Administration (OSHA) proposed a new rule lowering the occupational limit from 0.1 mg/m 3 (0.25 mg/m 3 for the construction industry) to 0.05 mg/m 3. 1 The current standard was set in 1971. Although regulation of occupational exposures at the current standard has
Silica is the biggest risk to construction workers after asbestos. As a very fine airborne dust prolonged exposure can cause lung cancer and other serious respiratory diseases. Silica dust is classified as Group 1 carcinogen by the IARC meaning they are seen as a definite cause of cancer in humans.
Silica classed as carcinogenic important information for you and your workers. On 11th July 2017 the European Council voted to include work involving exposure to respirable crystalline silica dust generated by a work process in Annex 1 Of the Carcinogens and Mutagens Directive. This new text must now be included within this Directive
In the workplace these materials create dust when they are cut sanded down etc. Some of this dust may be fine enough to reach deep inside the lung this is known as respirable crystalline silica...
Exposure of workers to respirable crystalline silica is associated with elevated rates of lung cancer. The strongest link between human lung cancer and exposure to respirable crystalline silica has been seen in studies of quarry and granite workers and workers
Silica is a natural substance found in varying amounts in most rocks sand and clay. For example sandstone contains more than 70% silica whereas granite might contain 1530%. Silica is also a major constituent of construction materials such as bricks tiles concrete and mortar.
