US4216713A - Can crushing mechanism - Google Patents

An apparatus for crushing cans uses a pair of guide rods having an anvil attached at each end, and a pair of sliding rams sliding on the guide rods. Can support wire members are positioned between each ram and anvil to support a can during crushing. A ram drive cam alternately drives each ram to crush a can against its associated anvil.

Proppant Crushing Mechanisms Under Reservoir Conditions ...

Dec 15, 2018· Proppant crushing, a major proppant failure mechanism, occurs in geothermal energy and oil/gas stimulation production stages when the level of net stress exerted on the proppant exceeds the actual crush resistance of the material. Loss of effective reservoir conductivity due to proppant crushing can result in significant loss in productivity, and so it is crucial to understand the realistic ...

Crushing Mechanism for Soil Particles

1. Introduction. This is the study to understand the crushing mechanism quantitatively for the development of rod mill device for soil. When a soil sample is examined at a research institute, the soil must first be crushed into fine-grained particles, with a median diameter of less than 2 mm, to satisfy industrial standards.

Crusher - Wikipedia

A jaw or toggle crusher consists of a set of vertical jaws, one jaw is kept stationary and is called a fixed jaw while the other jaw called a swing jaw, moves back and forth relative to it, by a cam or pitman mechanism, acting like a class II lever or a nutcracker. The volume or cavity between the two jaws is called the crushing chamber.
