Feed material drops onto the impeller table or enclosed rotor which, through centrifugal force, throws the material against stationary anvils made up of composite alloys. When …
The use of long shaft vertical pumps is common practice in the nuclear waste processing industry. Unfortunately, when such pumps employ plain cylindrical journal bearings, they tend to suffer from rotordynamic instability problems due to the inherent lightly-loaded condition that the vertical orientation places on the bearings.
The efficient and versatile design of Kolberg-Pioneer, Inc.'s Vertical Shaft Impactors (VSI) delivers highly-consistent end products for jobs that demand precision. Our VSI …
L Series vertical shaft impact crushers use high-speed rotor or heavy duty open tables. These crushers are offered in a variety of enclosed rotor or open table configurations and are convertible between three styles of crushing chamber designs for maximum flexibility.
In three 2010 papers, Tsujimoto, Ma, Song, and Horiguchi [1–3] discussed and explained a novel destabilizing mechanism arising in both hydraulic turbines and the back surface of vertical pump ...
In three 2010 papers, Tsujimoto, Ma, Song, and Horiguchi [1–3] discussed and explained a novel destabilizing mechanism arising in both hydraulic turbines and the back surface of vertical pump impellers. The destabilizing mechanism can be explained via a reaction force-moment model that includes both the customary radial displacement …
Moving on from the squat, chunky Seraph and its basic manned multirotor design, Britain's Vertical Aerospace has released designs for an upcoming five-seat tilt rotor air taxi it's calling the VA ...

They can not be used as secondary crusher since their maximum feed size is not big enough. But they are ideal machines for final product. They can crush the hard and abrasive material with low operation costs because of the crushing chamber design with …
Portable Vertical Shaft Impact Crushers are wheel-mounted rock crushing machines, engineered for tertiary or quarternary crushing applications. Equipped with a vertical shaft impact crusher and a feed hopper with belt feeder, it is used in the last stage of a multistage crushing process or as a stand-alone unit processing pre-crushed material.
