VSI Stands for Vertical Shaft Impactor. The material to be crushed is fed into the center of the rotor, which then throws it outwards towards the rock chamber walls. The material collides with the rock chamber walls and breaks into smaller pieces. The material then falls down to the bottom of the crushing chamber.

Basalt is the best material in the stone used in the repair of roads, railways, and airport runways. It has the advantages of wear resistance, low water draft, poor electrical conductivity, strong compression resistance, low crushing value, strong corrosion resistance, and asphalt adhesion and is recognized internationally as the best cornerstone for the …
A material with a very high average crushing strength but with 10% of material having very low strength is not necessarily ideal. It is important to consider not only the average strength of the DRI but also the standard deviation and minimum values. This is a demonstration of the importance of ore selection.
Hi, I am trying to select an alternative material to be used for a shaft that is currently made of H13 steel. The service requirements are that the shaft is exposed to an operating environment of 300-400C (about 572F-752F) with cooling water inside the shaft cooling the shaft as it creates torque attached to a motor, which is operating inside an industrial scale …
Material Used for Shafts The material used for shafts should have the following properties : 1. It should have high strength. 2. It should have good machinability. 3. It should have low notch sensitivity factor. 4. It should …
Shaft Materials:-• A good practice for material selection: – Start with an inexpensive, low or medium carbon steel for the first time through the design calculations. If strength considerations turn out to dominate over deflection, then a higher strength material should be tried, allowing the shaft sizes to be reduced until excess ...

Prob. # 3] A shaft and key are made of the same material and the key width is one-fourth the shaft diameter. a) Considering shear only, determine the minimum key length in terms of the shaft diameter. b) The shear strength of the key material is 75% of its crushing strength.
Total revolutions of shaft = 900x 10 6 revs. Shaft /Hub/keyway material (BS EN 10083 C45 normalised. Ultimate tensile strength 580MPa, Yield stress approx 300 MPa based on the table on webpage Factors. I've selected a shear strength = S s = 200 MPa, and a compressive strength = S c = 130 MPa
Torsion of Shaft with Keyway. In this calculation a shaft of length L, diameter D, with keyway dimensions K × H is considered.. The shaft is under torque T, applied to the end.As a result of calculations, the total twist angle φ and the maximum shear stress τ are determined.. For the calculation, the elastic modulus E and Poisson's ratio ν of the bar should be specified.
Stresses: Since compressive stresses do not cause fatigue failure, the bearing pressure is limited by the material yield strength YS of the weakest part, commonly the hub. The maximum shear stress in the key and the maximum torsional shear stress in the shaft can be derived from the yield strength of the shaft material.
