Embodiment 1
[0017] Embodiment 1: as figure 1 , a high-efficiency desliming process, including desliming roughing, desliming selection and desliming sweeping, the specific steps are as follows:
[0018] Firstly, the pulp raw material is transported to No. 1 cyclone for desliming and roughing. The specification of No. 1 cyclone is φ100, the ore feeding pressure is 0.15-0.2MPa, and the ore feeding concentration is 8-20%; The particle size content dropped to about 20%, and the -10μ particle size content in the overflow rose to about 65%;
[0019] Next, the grit produced in the No. 1 cyclone is transported to the No. 2 cyclone for desliming and refining. The specification of the No. 2 cyclone is φ100 or φ75, the ore feeding pressure is 0.15-0.2MPa, and the ore concentration 15-25%, the -10μ particle size content in the sand settling is further reduced to about 10%, and it is a qualified selected material, and the -10μ particle size content in the overflow rises to about 40%, and it is returne...
Embodiment 2
[0021] Embodiment 2: as image 3 , a combined equipment for high-efficiency desliming process, consisting of No. 1 sand pump pool 10, No. 1 slurry pump 9, No. 1 cyclone 2, No. 2 sand pump pool 8, No. 2 slurry pump 7, and No. 2 cyclone Flow device 4, No. 3 sand pump tank 11, No. 3 slurry pump 12, and No. 3 cyclone 19; No. 1 sand pump tank 10 is equipped with ore pulp raw material 1, and the inlet of No. 1 slurry pump 9 is connected to No. 1 Sand pump pool 10, the outlet is connected to No. 1 cyclone 2; No. 1 cyclone 2 has sand outlet A 14 and overflow outlet A 3, and sand outlet A 14 is connected to No. 2 sand pump pool 8; No. 2 slurry The inlet of the pump 7 is connected to the No. 2 sand pump pool 8, and the outlet is connected to the No. 2 cyclone 4; the No. 2 cyclone 4 has a sand settling outlet B 6 and an overflow outlet B 5, and the sand settling outlet B 6 is an output port. The outlet B5 is connected to the No. 1 sand pump pool 10; the overflow outlet A3 is connected t...
Embodiment 3
[0024] Embodiment 3: as figure 2 , a high-efficiency desliming process, including coarse and fine classification, desliming rough selection, desliming selection, desliming sweeping, the specific steps are as follows:
[0025] Coarse and fine classification: the pulp raw material is first transported to the No. 4 cyclone, the specification of the No. 4 cyclone is φ250, the ore feeding pressure is 0.08-0.1MPa, the ore feeding concentration is 15-30%, and the sand is mainly coarse-grained materials, +0.037 The mm size content is more than 85%, and the -10μ size content is less than 5%. It can be used as a qualified material for selection; the overflow is mainly fine-grained materials, with a -0.037mm size content of about 15%, and a -10μ size content. About 40%, enter the following desliming process.
[0026] Desliming rough separation: the overflow of the No. 4 cyclone is transported to the No. 1 cyclone, the specification of the No. 1 cyclone is φ100, the ore feeding pressure...
