Abstract

The invention discloses a multistage phosphorite screening unit. A first plane screen is disposed at a discharge hole of a feed hopper. An oversize discharge hole of the first plane screen is connected with a first belt conveyor through a guide rail. An undersize discharge hole of the first plane screen is provided with a first gate valve. The oversize discharge hole of the first plane screen is connected with a second plane screen below the first gate valve. An oversize discharge hole of the second plane screen is connected with a second belt conveyor through a guide rail. An undersize discharge hole of the second plane screen is provided with a second gate valve. The undersize discharge hole of the second plane screen is connected with a rotary screen below the second gate valve. A coarse material discharge hole of the rotary screen is connected with the second belt conveyor through a guide rail. A fine material discharge hole of the rotary screen is connected with a third belt conveyor through a guide rail. With the first gate valve and the second gate valve, the multistage phosphorite screening unit allows grading degree and destinations to be selected according to actual conditions of exploited ore.

Description

technical field [0001] The invention relates to a multistage sieving device for phosphate rock for sieving the phosphate rock into ores of different grades. Background technique [0002] At present, the vast majority of domestic phosphate rock enterprises mine the rich and abandon the poor, and abandon the ore that does not meet the economic taste, which will inevitably lead to serious ore dilution. In order to effectively utilize the country's rare resources, it is necessary to mine the thin ore body in full layers, and the ore mined in this way is difficult to meet the chemical requirements. In order to improve the grade of the ore, it is inevitable to sort the mined ore. The existing technology The sorting work in the process is generally relatively simple, and the mined phosphate rock cannot be screened according to the requirements of the phosphorus chemical industry for the grade of phosphate rock and the actual situation of the ore itself. Contents of the invention ...
