Cryogenic Grinding Consumption-GOLD MINING


A Review on Cryogenic Grinding - Inpressco

Cryogenic grinders have higher production rate along with it more uniform particle distribution. The experimental data vary with different sized, nature of feed material and also with change in configuration setting of cryogenic grinding machine. Table1.1 Specifi ions for Cryogenic grinders Power consumption 160 watts

▲Figure 1: Many factors affect liquid nitrogen consumption in cryogenic grinding. As a result, consumption in very similar plants can vary by a factor of three or more the same throughput, and it tends to narrow the product particle size d i s t r i b u t i o n.

Review of Optimized Technologies for Cryogenic Grinding

The theoretical consumption of LN2 was calculated. Measurements at production plants showed that the real consumption is sometimes much higher than the theoretical theoretical to the practical consumption, the efficiency factor glN2 is defined as- At a cryogenic grinding plant in the chemical industry, this


Cryogenic grinding provides higher production rate, lower energy consumption, finer particle size, more uniform particle distribution, lower grinding cost,.no heat generation which is good while grinding spices and provides an inert atmosphere thus eliminating the possibility of oxidation.

Cryogenic grinding involves cooling a material below its embrittlement temperature with a cryogenic fluid, typically liquid nitrogen or, in certain appli ions, carbon dioxide. After cooling, the material is fed into an impact mill where it is reduced in size primarily by brittle fracture. This process has several benefits:

Cryogenic grinding performance of scrap tire rubber by .

The key step of cryogenic grinding is to freeze the rubber so that it is in a brittle state. This freezing process consumes a large amount of refrigerant, such as liquid nitrogen, and results in a high cost for rubber powder production. The cost problem has already become a strong factor hindering the development of cryogenic grinding process.
