Problems solved by technology

[0004] The above-mentioned patents only use vibrating sieve to remove impurities. Since the diameter of the sieve hole of the vibrating sieve is small, when the output increases, the flow rate of the ore pulp will also increase accordingly. The ore pulp, even part of the incompletely screened ore pulp will be discharged from the sand discharge port, resulting in waste of ore pulp

Embodiment Construction

[0037] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0038] A kaolin desanding process, comprising the following steps:

[0039] Step 1: Spray water on the surface of kaolin to form ore slurry and flow into the slurry pool;

[0040] Step 2, use the stirring paddle to move the ore pulp to the stirring tank, and fully stir the ore pulp in the stirring tank;

[0041] Step 3, send the uniformly stirred ore slurry into several parallel hydrocyclones, in this embodiment, there are 4 hydrocyclones, and the overflow slurry is sent to the iron removal process;

[0042] Step 4, the underflow of the hydrocyclone enters the rotary vibrating screen for secondary screening, the slurry passing through the screen 8 is sent to the iron removal process, and the impurities on the screen 8 are discharged out of the rotary vibrating screen through vibration.

[0043] Such as figure 1 As shown, the rotary vibrating screen...

Abstract

The invention discloses a kaolin sand removal process and relates to the technical field of kaolin production. The technical point is: a kaolin desanding process, including the following steps: step 1, spray water on the surface of kaolin to form a slurry and flow into the slurry pool; The pulp is fully stirred; Step 3, the uniformly stirred pulp is sent to several parallel hydrocyclones, and the overflow slurry is sent to the iron removal process; Step 4, the underflow of the hydrocyclone enters the rotary vibrating screen for secondary screening , the slurry passing through the screen is sent to the iron removal process, and the impurities on the screen are discharged out of the rotary vibrating screen through vibration. The invention has the advantages of high screening efficiency and not easy to waste ore pulp.

Description

technical field [0001] The invention relates to the technical field of kaolin production, more specifically, it relates to a kaolin desanding process. Background technique [0002] Kaolin is a non-metallic mineral, mainly composed of kaolinite, mica, residual feldspar and quartz, and is a kind of clay and clay rock mainly composed of kaolinite clay minerals. The main component of kaolin is mainly aluminum-containing silicate minerals, and the particles are fine and white and fine. Kaolin is widely used, mainly used in papermaking, ceramics and refractory materials, followed by coatings, rubber fillers, enamel glazes and white cement raw materials, and a small amount of plastics, paints, pigments, grinding wheels, pencils, daily cosmetics, soap, Pesticides, pharmaceuticals, textiles, petroleum, chemicals, building materials, national defense and other industrial sectors. [0003] The Chinese invention patent with the publication number CN106944254A discloses a kaolin purifi...
