Once the flirtation machine operates, the motor drives the impeller to revolve, thus the centrifugal impact and negative pressure are designed. Similarly, ample air is absorbed and combined with mineral slurry, nevertheless, the mixed mineral slurry is mingled with additive, meanwhile, the foam are loss, the mineral is bounded with foam, and floats as a lot because the leading of mineral slurry as well as the mineralized foam is developed. The liquid surface could be modified using the height of adjustment flash board, to make sure that the useful foam are crawled with squeegee.
This production line a high degree of automation, low operation cost, high grinding efficiency, energy saving, large output, less pollution, easy maintenance, sand production mechanism conforms to the country's building standards, products is granularity, good grain shape, gradation and reasonable.
6.Dewatering is the process of removing some of the water from the tailings-water slurry following concentration.
Besides, the mesh size can be adjusted from 3mm to 50mm, suitable for separating iron ore particles into required gradations.5-80tph, suitable for the required 80tph production scale.According to the requirements of the customer, the engineer recommended Zenith 3YK1237 circular vibrating screen for him to process the iron ore. And the 3YK1237 vibrating screen has 3 layers that separate the iron ore particles 3 different sizes. The production capacity range of this vibrating screen is 7.
9 microns, is characterized in that the suspension is prepared using the abrasive described above.The process according to the invention for preparing an aqueous suspension of comminuted lime, in which the suspension has a dry matter content of at least 20% by weight, preferably 40-60% by weight and a median diameter of less than 2. according to the following steps: a) a coarse-grained lime water suspension is prepared by stirring by first feeding all or part of the grinding medium into the aqueous phase and then lime to give a liquid and preferably homogeneous suspension, b) feeding the suspension prepared according to a) into a continuous grinding zone c) the temperature of the suspension is kept below 100 ° C during grinding and preferably at a temperature between room temperature and 50 ° C, 9 92924 d) the suspension to be ground is mixed in the presence of the micromill bodies to the required a (e) at least one additional fraction of grinding agent is fed at least once during grinding,.
These giant mounds of remains symbolise a distinct sense to requalify the devastated landscape and to reuse the rest in situ . The future directions of the current investigation suggest replacing not only the former industrial pits, but also the gigantic heaps of remains located at their side, linking the two components . These interventions will be connected to the inactive quarries and they will be incorporated into the surrounding landscape. This study is also concerned with the Anticlinal of Estremoz, in Portugal, consisting of an area of 280 km2 formed by approximately 200 marble quarries, each of which is flanked by an enormous pile of wastes (about 15 m high).In this regard, it is necessary to underline that this literature review article is only a minor part of the broader research focused on innovative strategies of quarry rehabilitation. They are the principal factors to promote tourism in the place, through the addition of new structures between, above, and inside them.
