Silicon carbide powder (SiC) was comminuted in a planetary mill during time intervals of 0.5, 2, 4 and 6 h. The wet milling media was ZrO 2 spheres in isopropyl alcohol. The powders were then characterized with respect to chemical composition, particle size distribution, surface area and density for each milling time.

all our products are micronized with appropriate materials (o.a. jet mill, ball mill with ceramic inliner and non-ferrous grinding balls) to produce ultra fine powders down to 5 microns for various advanced applications tailor-made powder on request

method is more efficient in achieving fine particle size. Rod mills: Horizontal rods are used instead of balls to grind. Granularity of the discharge material is 40-10 mm. The mill speed varies from 12 to 30 rpm. Planetary mill: High energy mill widely used for producing metal, alloy, and composite powders. Fluid energy grinding or Jet milling:

Unless producing very fine particles is the objective, it usually is more ... Air aspiration is often used, especially in jet mills, to remove fine particles by entrainment while retaining larger particles. Hammer, ball and rod mills frequently have screens on their discharge to ... precipitates a very fine powder. This approach can be used for ...
