DESIGN AND ANALYSIS OF IMPACT CRUSHERS

A crusher is a machine designed to reduce large solid chunks of raw material into smaller chunks. Crushers are commonly classified by the degree to which they fragment not starting material with wares crushers not reducing it by much, intermediate cruiser fragmenting it much more significantly and grinders reducing it to a fine power.

Gyratory Crusher an overview ScienceDirect Topics

The gyratory crusher shown in Figure 2.6 employs a crushing head, in the form of a truncated cone, mounted on a shaft, the upper end of which is held in a flexible bearing, whilst the lower end is driven eccentrically so as to describe a circle. The crushing action takes place round the whole of the cone and, since the maximum movement is at the bottom, the characteristics of the machine are

In Situ Leach Mining (ISL) of Uranium World Nuclear

In situ leaching (ISL), solution mining, or in situ recovery (ISR) involves dissolving uranium in the ground and pumping the solution to the surface where the minerals can be recovered. Information from the World Nuclear Association, the global private-sector organization that provides information on nuclear power, nuclear energy, and the role of nuclear in sustainable development.

Synergetic Oxidation in Alkaline In-Situ Leaching Uranium

In alkaline in-situ leaching uranium, oxygen is the most common oxidizer with bicarbonate as a complexing agent. For those sandstone uranium deposits with strongly reductive capacity or complicated hydrogeological environment, the oxidation by oxygen is low efficiency. An efficient leaching method, therefore, is needed for these uranium deposits.
