For example, coarse crushers have size reduction ratios of below 8:1, whereas fine grinders may have ratios as high as 100:1. However, large reduction ratios, such as those obtained when dividing relatively large solid lumps into ultrafine powders, are normally attained by several stages using diverse crushing and grinding machines.

The growing demand for ultrafine powders, coupled with stringent quality requirements, calls for continuous improvements in all aspects of fine particles production. The high energy costs involved in comminution is also an additional motivator. The equipment most commonly used in fine particles processing and the related process …

Rotary surface grinders or commonly known as "Blanchard" style grinders, the grinding head rotates and the table usually magnetic moves in the opposite direction, this type machine removes large amounts of material and grinds flat surfaces with noted spiral grind marks Used to make and sharpen; burn-outs, metal

With a reduced particle size, the solubility of ultrafine powders increased significantly (P < 0.05), whereas the water holding and swelling capacities decreased with a reduced particle size and then increased. Fourier transform infrared spectroscopy analysis showed that ultrafine grinding did not damage the main cellular structure of GS powder.
