First  Various production processes metallurgical mines, will generate dust, such as effective measures are taken, these serious pollution job site dust will harm the health of workers, especially the more dangerous fine particles of respirable dust, silicosis caused by such dust is mixed The root cause of occupational diseases such as silicosis. Dust will also accelerate mechanical wear, and if the mineral powder is not recycled, it will directly cause the company's resources and economic losses. Therefore, doing a good job of safety and preventing dust hazards is a meaningful work. It is a major event directly related to the health of the company's employees and the long-term development of our company. It cannot be ignored.
Second  All units that have dust operations must take effective dust-proof measures and conscientiously implement the "prevention-oriented" policy. Adhere to the effective feng shui-based "wind, water, dense, protective, grass, pipe, teaching, inspection" eight-word ventilation and dust-proof measures, so that the dust concentration of each operating point meets national health standards.
Article 3 Â Establish and improve the dust-proof team, equipped with the necessary technicians and workers. According to our company's situation, the general ventilation personnel are arranged in the following proportions.
1, Â Â Â All mining workshops are equipped with full-time ventilators, and the proportion of personnel should be 2% of the workshop staff.
2, Â Â Â Company security management and technical personnel with a dust-proof ventilation, Inoue production units with no full-time staff.
3, Â Â Â All units must ensure the stability of ventilation and dustproofing, and give full play to their role.
Article 4 Â The sealed wall and damper shall not be removed without the approval of the safety management department. The ventilation and dustproof equipment and facilities shall not be dismantled without the consent of the ventilation and dustproof management personnel.
The fifth  Ventilation and dustproof workers must have a strong sense of responsibility, be responsible for the health of workers, often ventilate the work surface, do not neglect their duties, and prevent the occurrence of gun poisoning accidents.
Article 6 Â Downhole operators must adhere to wet work, wear protective equipment, and consciously abide by safety technical operating procedures.
Article 7  The safety management department shall report the “dust report monthly report†to the higher authorities in accordance with the regulations, and notify the production units of the dust in a timely manner to take necessary dust reduction measures.
eighth  Every year, a dust check is conducted for the dust-collecting personnel. A health card for dust-collecting personnel is established. If a patient with silicosis or a suspicious patient is found, the relevant unit should be notified and the work type should be immediately replaced and the treatment should be removed from the dust.
Double-Cone Rotary Vacuum Dryer
As a professional drying equipment manufacturer, we provide more than hundred sets of equipment for our users. The heating media such as high temperature heat transfer oil, middle temperature steam and low temperature hot water are available for our products. When drying viscous materials, we can design the special [copying" mechanism or set balls in the tank for you.
Applications:
It is suitable for concentration, mixing and drying of powder, granular and fibrous materials in such industries as chemical industry, medicine, food, etc., and materials that require low temperature drying(such as biochemical products), and is more suitable for drying of materials that are easy to oxidize, volatize, heat sensitive materials, irritant and poisonous materials, and materials in which breaking of crystals is not allowed.
Principle:
• After the heat source(such as hot water, low pressure steam or heat transfer oil) is connected to the closed jacket, the heat is transferred from the inner shell to the materials to be dried.
• Driven by the power, the tank makes slow rotation and the materials in the tank are continuously mixed so as to realize the purpose of drying.
• When the materials are under vacuum, the steam pressure reduces to make the moisture(solvent) on material surtaces reach the saturation status and evaporate, and discharged and recovered timely from the vacuum pump. The moisture(solvent) inside the materials is penetrated, evaporated and discharged towards the surfaces. The three processes are carried out continuously, so that the materials are dried within a very short time.
Features:
• During oil heating, automatic constant temperature control is adopted to dry biochemical products and mineral raw materials.
Temperatures vary within the range of 20-160℃.
• The heat efficiency is 2 times higher than that of common ovens.
• Indirect heating will cause no pollution to the materials, conforming to GMP requirements. The equipment is simple to repair and operate and easy to clean.
