Dewatering Screen - Mineral Processing
Counter-rotating vibratory motors (or mechanical exciters on the largest of Dewatering Screens) create a linear motion at an angle to the screen surface that accelerates the solids upward and forward at 5G. This, along with a generous stroke length, moves water through the countless openings between the particles to promote droplet formation.

SCREEN CAPACITY CALCULATION - 911 Metallurgist
2016-9-15 is not always justified. A scalping screen used as a finishing or dewatering screen would have a greatly reduced capacity. A finishing screen used as a heavy scalper would also have a greatly reduced capacity. The type of stroke, length of stroke, screen rpm, timing angle, and incline of the screen greatly affect the basic capacity.

Strategies to Optimise the Use of Hi-Flow Dewatering ...
2019-3-7 They're shaped and made to work in tandem with a pair of carefully tuned vibratory motors, whose stroke length forcibly boosts the decks' drainage energy. For that ultra-fine final-stage screening media to work properly and output its drip-free mass, the hi-flow dewatering decks must be carefully optimised. This takes place in two ways.

How Stroke And Rpm Of Vibrating Screen Are Related
The slope of the inclined screen is fixed although the stroke can be adjusted to the required level The general working stroke of an inclined screen is between 8 and 12 mm and design of inclined screens permits changes to this stroke through the addition or removal

Horizontal Screens - Aggretek
Adjusting the stroke angle has been found to be the most influential in optimizing the screen efficiency. Higher stroke angles increase the number of chances the material has to pass through the openings and also increases the impact to shake fines loose. Lowering the stroke angle increases the travel rate for heavy screening or scalping operations.
