Screen Stroke The shape and amplitude of the motion of a screen. Usually screen strokes are circular, oval or straight line strokes. • Open Area The area available on a screen for a aggregate particle to fall through a hole in a screen. Usually expressed as a percentage. • Screen Efficiency
Maximum vibrating screen production and efficiency is a result of many important factors. Some of these include: selection of the vibrator; length and stroke of the unit; feed rate and method of feed; direction of rotation of circular action; and finally, the selection of screening media with the proper "hook" or screen edge preparation.

Reduce the vibrating screen load and clean the screen surface. 3) Change inclination angle of screen box. 4) Regulate the screen feeding.
4.1 Classification Based on Sieving - Vibrating screens The basic method of operation of a screen is very simple. The screen presents a barrier to the passage of oversize material while it readily passes undersize material. It is only necessary to ensure that each particle has an opportunity to reach the screen.
The screen body is supported by coil springs on which the body can bounce freely. The vibrating motion thus is given by counterweights built on the shaft. Depending on the location of the shaft, GELEN two bearing inclined screens have two types: ET-S Series Circular motion screens and ET-SI Series Grizzly screens with center mounted counterweights.

Allowable Stroke When applying a Marsh Mellow spring, the stroke throughout the range of motion of the machine being isolated must be considered. Delta strain, defined as the ratio of the stroke to the free length, is restricted to less than 7.5%. Note that a given stroke is typical of vibrating screen
Freely vibrating screens. By freely vibrating screens one means screens that are supported on springs, and the box is vibrated by a vibrating mechanism (also called an exciter) which vibrates the screen box in various ways, depending on the type of vibrating unit. Circular motion. Screens with a circular motion are the most common type.
Kason Vibroscreen ® circular vibratory screeners (also called separators and sieves) separate bulk solid materials from solids and slurries using multi-plane, inertial vibration that causes particles to pass through apertures in the screen or to travel across the screen surface in controlled pathways.
overly optimistic. The biggest assumptions are the screen will have the correct rpm and stroke length for the given application. Also, there are some obvious errors in the published tables. Most manufacturers use a modified version of the VSMA (Vibrating Screen Manufactures Association) formula to determine screen capacity. The twelve factors
Stroke of the screen (measured) Frequency of the current to the motor From the number of poles of the motor, the moto's shaft rotational speed can be calculated, using the following formula:

A circle-throw vibrating machine is a screening machine employed in processes involving particle separation. In particle processes screening refers to separation of larger from smaller particles in a given feed, using only the materials' physical properties.
Vibrating Screen In addition to providing crushers and rock and mineral processing equipment, propel has gained commendable reputation in vibrating equipments like screens, feeders and scalpers for most demanding applications in multi-stage crushing plants and mobile installations.
Circular vibrating screen use gravity to help move material down the deck and a circular stroke to stratify the material for sizing. It is available for smelting, quarry, coal preparation, ore dressing, energy, power, chemical, construction material industries. Its screen angle can be adjusted from 15-20° .
Alternatively, on a 20-degree incline and at 70 to 75 ft. per minute travel rate, an incline screen will deliver up to 25 percent more capacity than a linear-stroke horizontal machine. Unlike the latter, the circular motion of an incline screen results in less stress to the vibrating frame. DEWATERING SCREENS
