A Silicon Carbide Powder Production Process, Characterized By The Following Steps:

(1) take the SiC raw material is crushed by the crusher, and sieved to no more than 5mm in the silicon carbide particles, and then shaping machine to its shaping to the silicon carbide particles of not larger than 2mm, and wherein the oval-shaped particles accounted for more than 80%, and then its pickling purify, dry;

(2) will be above the dry silicon carbide particles with a milling machine pulverized into d50 = 9.5-11.5μm of the silicon carbide powder, pulverizing, milling machine host current is set to 65-75A, the flow of the fan is set to 40 – 50m3/min, analysis machine speed of 400 – 600 rev / min;

(3) then with the eddy current type gas stream classifier of the silicon carbide powder classification, when classified vortex type air classifier fan flow 25-43m3/min, and classifier wheel rotational speed of 2600 – 3300 rpm / points, the separation from the grading mouth granularity ds94 = 6.5-5.5μm finished product A whirlwind the mouth separate the ds94 ≤ 5.5μm semi-finished products;

(4) with a the cyclonic vortex type gas stream classifier mouth the separated semi-finished impeller-type gas stream classifier then the secondary classification, when classified with the impeller fan flow of the gas stream classifier 25-10m3/min classifier wheel speed is 1300 – 1700 rev / min, was separated from grading port granularity ds94 = 4.5-3.0μm finished B Cyclones mouth is separated byproducts.

Powder grinding equipments mainly include raymond pulverizer,high strength pulverizer,micro powder,patent mill,bucket elevator and belt conveyor,etc.High performance screening machine in the high flow processing, can be rapidly cleared the percentile a low content of large particles or small particles separated from the pulp. TS vibration screening function to the rapid removal of the insoluble solid matter in the various types of slurry and continuous slag.

Sieving the granules, powders into different particle size segments. Single TS vibration screening machine can be equipped with up to four layers sieve consecutive sub-elect 2-5 grain size and control a narrow particle size range.
