The environmental pollution in the production of boron industry in China is relatively serious. Such as waste water produced in underground mining, gas, waste, dust, noise and so have an adverse effect on health and environment of workers; secondly, the amount of boron peat-alkali process only boron iron ore production reached borax produced a year It is 100 to 1.2 million tons, and its stacking not only occupies land but also pollutes the environment. For this reason, it is of great significance to control the pollution of wastewater, waste gas, waste residue, noise and radioactive materials to meet the emission standards and quality requirements stipulated by the national or local people's government.
Mine wastewater
The wastewater from boron mines is mainly derived from boron-containing external drainage in mines and open pits. At present, some mines adopt a treatment method that uses lime water to coagulate, produces calcium borate precipitates, and discharges or reuses the cleaned water after sedimentation.
2. Ventilation and dustproof in the pit
Generally, underground boron mines use mechanical ventilation. The main section of the underground is equipped with a ventilator, and a local single-head working surface is provided with a fan exhaust ventilation. Measures such as spray dust reduction at the loading point and regular watering of the roadway to clean the rock wall.
3. Prevention of noise
Various electromechanical equipments such as underground boron mine mining sites, ventilation machine rooms, air compressor rooms, and crushing plants can generate noise during operation or operation, resulting in pollution of the surrounding environment. Some mines take individual protective measures against the types of work that are exposed to noise. Equipped with earplugs for personal protection for rock drilling workers. Add vibration, sound insulation and sound absorbing facilities to the surface air compressor station or ventilation room.
Track Cutting to Length Line suits making medium gauge metal sheets of over 1m length.
Medium gauge ranges from 1-8mm, length of finished sheets 1 -8m, line speed can be 50-60m/min, each steel coil can be cut within 30min.
Main equipments of track Cut To Length Line is leveler, servo roller measure, hydraulic track shear, auto stacker. The leveler is always running and the track shear cut sheet to length under servo length measuring.
With productivity improving demand in market, track shear is becoming popular, it can gives high production and high quality of flat sheets.
We supply custom cut to length lines to customers, make sure each cutting line work smoothly, earning profit.
