Portable Horizontal Screens

AGGRETEK Horizontal Screens are a combination of quality, reliability, and performance; providing a long service life while operating under the most demanding applications.
Nowadays, customers are requiring tighter specifications for products for precisely shaped aggregate or closely-sized stone. As a result, tighter control over the process is of utmost importance and the most effective point to do that is at screening. For that critical step you can trust AGGRETEK Horizontal Screens.

FEATURES

Full Length Spring Support
Spring supports capture all decks for added rigidity and stability. This improves resistance to side plate cracking. Fully broke non-welded huck-bolted standard. Option of marsh-mellow coil springs.

High Strength Screen Body
The body of the screen is extremely strong supporting the stresses required by the high power mechanism. This rigidity is provided by frames made from beam sections with stiffeners positioned in critical areas.

Huck-Bolted
Side plates are made from high quality steel and laser cut holes. Frames are huck-bolted to the side plates insuring structural integrity and eliminates stress fatigue in the screen body.

Motor Base
The motor base coupled with the belt tensioning system enables a practical motor assembly and V belt – pulley replacement, and provides energy efficiency by keeping the belt tension at the desired level. In addition, by providing a bolted connection between the motor frame and the main frame, cracks and fatigue issues associated with welding are avoided.

Oval Stroke Geared To Productivity

AGGRETEK Horizontal Screens generate power via three-shaft impulse mechanism located in the center of the screen body with eccentric counterweights. The combination of the three shafts provide an oval stroke with adjustable amplitude, speed and operating angle, determined by application.

Oval stroke screen action combines the best features of the circle and straight line throw into a unique oval stroke, by benefiting from the screening of the circle throw with the conveying action of the straight line. The motion is nearly vertical through the initial lift phase of the stroke, and the openings in the screen cloth are perpendicular to the material. This provides optimum alignment and maximum probability of material passage through the screen openings.

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. Higher speed is sometimes desired for scalping duty.

Other benefits include:

  • Less horsepower required
  • Smooth running-eliminates jerking action of straight stroke screens
  • Adjustable angle and length of stroke
  • High capacity and efficiency
  • High G force action for better material stratification, reduced plugging and greater range of screenable material

Wire Cloth Stretching System

Screen meshes are fastened to the screen body by means of screen clamps and sheet bars, after being well stretched at the edges by the tension sheet. Thus, any slackening of the screen meshes during the screening process is prevented.

Other Benefits

– Lower operation noise

– Increase safety for operators

– Smoother shut down of the screen

Bearing and Lubrication

Self aligning taper roller bearings are used to withstand the high thrust and radial loads under which the drive shafts of the triple drive system operate. The roller bearing lubrication is carried out by oil lubrication in an oil bath, which reduces operating temperature for increased bearing life and results in low maintenance.

Mounting Arrangement

Coiled springs or with reinforced rubber springs depending on the application. Coiled spring is used when there is no threat of corrosion or abrasion, when there are plenty of opportunities for maintenance and spring replacement, and when loss of time due to problems caused by spring fracture is not an issue. Rubber spring should be used when there is a risk of corrosion or abrasion, when there are limited opportunities for maintenance and spring replacement, and where any halt in production will result in significant costs.
