What is banana screen?
Used in wet and dry applications, banana screens are vibratory equipment which use the distinctive shape to process larger volumes of material using a smaller footprint. This is compared to inclined horizontal screens, which as the name implies are horizontal and donʼt have the banana shape.
What is exciter gearbox?
Directional Force Geared Exciter is a heavy-duty gearbox used to create linear vibrations for bulk material handling with high feed rates. The gearbox consists of two counter-rotating shafts with two counter weights each, which create ample resultant centrifugal force or unbalance to produce linear motion for vibrating.
How many types of vibration screens are there?
The two most common types of vibrators which induce the high frequency vibrations are hydraulic or electric vibrators, these electric vibrators are either electric motors or solenoids. Common designs for screening decks are either single or double deck.
What is screening machine?
A screening machine consist of a drive that induces vibration, a screen media that causes particle separation, and a deck which holds the screen media and the drive and is the mode of transport for the vibration. There are physical factors that makes screening practical.
What is a screen exciter?
Exciters are the main vibration source of the screens. They generally comprise a housing, bearing, shaft and an eccentric mass. The vibration results from the rotation of the eccentric mass about the exciter shaft.
What is unbalance exciter?
AViTEQ Unbalance exciters are designed for producing linear motion for medium and large size vibrating machines operating in many industrial processes. The design is engineered for safe operation in continual operation with 100% centrifugal force.
What is stroke of vibrating screen?
Horizontal screens are equipped with triple drive mechanisms that produce an elliptical vibration motion at the required stroke and slope. The stroke of horizontal screens may be adjusted in a range of 14–20mm, although they generally operate with a stroke of between 16 and 18 mm and with a 750 rpm rotational speed.
How do I choose a vibrating screen?
Choosing the Proper Vibratory Screener
- Maximum feed rate in lb/hr, tn/hr or metric tn/hr.
- Bulk density of the material to be screened in lb/cu ft or kg/cu m meter.
- Screen opening(s) required to make the specific separation(s)
- Sieve analysis (particle size distribution or gradation) of the feed material.
Which of the following screen is called as jiggling screen?
The slightly inclined shaking screen is favored. Also called jiggling screen.
How does a trommel work?
A trommel is a screen that is curved into a cylinder. The machine spins the cylindrical screen in order to sort through the material as it is fed through. During this process, the wet material tumbles around. Air is added and the soil, mulch, or sand becomes lighter and drier.
