In recent years, along with the national policy requirements more and more strict green mines, many plants have begun to hair mineral dry drainage project, which for some enterprises engaged in tailings discharging dryly provide opportunities, but in dry tailings discharge enterprises blossom everywhere at the same time, also accompanied by.
The tailings discharging dryly do not know much about people generally think of dry tailings discharge process is very simple, a few simple device can be constructed, it is thoughts and ideas that lead to the market of tailings discharging dryly quality uneven, so many technical force is not enough small business loopholes, plant selection for many eager to hair mineral dry discharge project caused unnecessary losses. A really good dry tailings discharge process is according to the requirements of customers customized.
Xinhai group as the first batch of domestic investment strong technical force of dry tailings discharge technology research and development enterprises, in Xinhai Technology Director, domestic dry tailings first people led by Yu Yongjiang, to the dry tailings discharge process conducted in-depth research for many years, the earliest developed the dewatering screen is applied to the process of tailings discharging dryly, thus greatly reduce the thickener models, saving the area. At the same time also designed a row of test bench stem first tailings at home, and made great contribution to the development of Chinese dry tailings discharge technology. In the years of customized for tailings discharging dryly experience, Xinhai dry tailings discharge technology team found to be customized for a cost-effective process of tailings discharging dryly, must tailings on the customer and factory actual situation clear, therefore a detailed survey plan is necessary, the following is Xinhai in years of customized tailing process summed up the need to survey data.
One, tailing quantity
The 1 day, concentrator tailings discharge (for staging to factory, design scale should have the date of tailings discharge)
2, the total discharge of tailings production period.
Two, characteristic of tailings
1, the proportion of tailings (coarse particles are significantly different when)
2, the dry density
3, particle composition (should obtain a divided by particle content, and the maximum particle size should not be greater than 5%, the minimum size should be analyzed to 5 microns or its content is not more than 10%)
4, concentration and consistency
Three, the process conditions of mineral processing
1, concentrator work system and design production period;
Position and elevation 2, tailings discharge;
3, mineral processing tailings backwater of water temperature and maximum return allowance (if necessary degree of test effect of flotation tailings backwater);
4, in the production process of tailings and tailings characteristics possible fluctuations
Four, the temperature of pulp
The cold area in winter is the coldest month concentrator tailings average minimum temperature, mainly considering the tailings conveying system in ice.
Five, the tailings settling characteristics and coagulation sedimentation property
The tailings settling in water:
Sedimentation velocity 1, tailings, for no clear interface of the tailings, requirements to determine the minimum design overflow particle size of free settling velocity;
2, the average concentration of different duration precipitation tailings;
3, different duration of purifying water, suspended matter content
To the settlement in the water very fine tailings:
1, the type and dosage of coagulant;
2, the settling velocity of floc settling velocity or clarify interface;
3, the flocculation sediment concentration
The above is the data to be collected Xinhai custom dry tailings discharge, which can be seen dry tailings discharge process is not simple, must be based on strong technical force to provide a perfect, the highest price of the tailings dry discharging technology to support for the customer, rather than simply several device can fix, so for want of real hair mine dried plant selection and arrangement of the project, must choose the technical strength of large enterprises, one is technical force is assured, two is to provide the highest cost-effective process, save cost.
