Ore supply system used for preparation of phosphoric acid from fine ores

Abstract

The invention provides an ore supply system used for preparation of phosphoric acid from fine ores. The system is composed of a fine phosphate ore pipeline (1), a hopper (2), a disk feeder (3), a conveyer (4), a sewage pipe (5), a flushing screen (6), a drum screen (7), a tailing outlet (8), a chute (9), a pulp stirring tank (10) and a pulp storage tank (11). The ore supply system used for preparation of phosphoric acid from fine ores omits the energy consumption cost of milling of a ball mill, has a simple structure, and also uses sewage generated in industries.

Description

technical field [0001] The invention relates to an ore supply system, in particular to an ore supply system for producing phosphoric acid from fine ore. Background technique [0002] With the development of science and technology, more and more attention is paid to environmental protection and energy conservation, which makes enterprises have higher and higher requirements for energy conservation and environmental protection. At present, the phosphate rock ore used to manufacture phosphoric acid is crushed by a crusher with high precision. Finally, they are all powdery phosphate rocks that have been crushed and can be used without grinding. If the original ball mill is used for grinding and then the phosphoric acid manufacturing system will result in over-grinding of powdery phosphate rock particles, the ball mill Grinding is not only noisy and energy-intensive, but also complicated in procedure, inconvenient for management and operation, resulting in consumption of electric...

[0002] With the development of science and technology, more and more attention is paid to environmental protection and energy conservation, which makes enterprises have higher and higher requirements for energy conservation and environmental protection. At present, the phosphate rock ore used to manufacture phosphoric acid is crushed by a crusher with high precision. Finally, they are all powdery phosphate rocks that have been crushed and can be used without grinding. If the original ball mill is used for grinding and then the phosphoric acid manufacturing system will result in over-grinding of powdery phosphate rock particles, the ball mill Grinding is not only noisy, high energy consumption, but also complicated procedures, inconvenient to manage and operate, resulting in consumption of electric energy and consumption of steel balls and steel forging, and high cost. Due to the expansion of production capacity of enterprises, the amount of water in the sewage station is large, and it is impossible to deal with it in time. Sewage treatment has caused water treatment problems. In order to solve these problems and improve process efficiency, a reasonable mine supply process system is required
