Potassium feldspar processing equipment process is as follows:

1. Crushing: First, the large stones are broken by a jaw crusher.

2. Ball milling: The crushed stone is ball milled with a ball mill.

3. Washing the mud: send 20-200 mesh fine powder materials into the spiral chute, separate and sort, and select the sediment;

4. Sorting: to remove the sediment after separation of the material into the shaker, wash the ferric oxide;

5. Selection: The material with iron oxide removed is sent to the 1024-type strong magnetic re-election machine for selection, iron and mica materials are selected, and then the material is sent to the 1018×2 type ordinary magnetic separator, and then sorted again. Note: At present, the use of magnetic separators in addition to iron in potassium feldspar is not suitable for all K-feldspar mines, and the flotation process has been widely used.

6. Purification: The re-elected and universally selected materials are sent to the high-frequency vibrating screen for screening, and the ferric oxide and triiron tetroxide in the powder are removed to obtain the potassium feldspar fine powder;

7. Pickling powder: using sulfuric acid as the pickling agent, according to the acid concentration and the iron content of the potassium feldspar fine powder, the iron content of the potassium feldspar fine powder is determined under the condition of determining the sulfuric acid concentration. The weight of the added sulfuric acid is proportional to the weight, and the iron oxide and the ferric oxide are completely removed by pickling, and the ferrous sulfate solution is separated to obtain the potassium feldspar fine powder;

8. Screening of potassium feldspar fine powder: The potassium feldspar fine powder is sent to a 20-200 mesh sieve, and the sieved product is a finished product having an iron content of less than 0.24%.
