Vibrating screen is a must-have equipment to screen materials in crushing plants known also as crushing and screening plants.
Job duty of vibrating screen is separating stone or ore material that are firstly extracted from stream bed and mines and then crushed.
What is Vibrating Screen?
Stone crushing, screening and washing plant is a large and developed facility where sand, the basic requirement of today’s building sector, is manufactured. Pure sand is transformed from stones and ores after many processes in the crushing plant. This process consists of many different machines and equipment working together. Screen is the equipment sorting the stones by size after they are broken.
Although there are many different types of screen in the market, vibrating screen is the most efficient and most preferred type today. The vibrating screen that possesses coil springs distributes material evenly coming from feeding bunker. The vibration moves small stones on the screen surface to the lower side, so large stones and small stones are separated.
Vibrating Screen Working Principle
The intended purpose of all screens is to separate the material in different sizes by passing it through the holes of the screen. Vibrating screens used in crushing plants classify the stones by separating them based on the desired product size.
If the rock is small enough, it will pass through the hole of the vibrating screen and go to the area under screen. The rock passing through the screen named as undersize. The larger size material that does not pass are discharged from the system and named as oversize discharge. Vibrating screens used today generally consist of many different layers. There are decks carrying a set of screen on each layer. If the size of material is small enough to pass through screen on a layer, it falls to a lower layer; if it is not small enough to pass through the screen, it is discharged from the system at the end of the layer where the screen is located. And, finally all materials coming from each layer exits separately through the product outlets. Thus, the rocks are separated into different classes by their sizes.
Types of Vibrating Screen In Terms Of Working Principle
There are different types of vibrating screens in the market depending on the design type, working principle, and the screen material used. Screen deck is divided into two groups in terms of inclination.
- Inclined Screen: It is one of the screens with the most common usage area today. The inclination rate of the screen can generally vary between 15 ° and 30 °. Eccentric weights of the inclined screens can vary. More weight of inclined screen and less height leads to low stroke.
- Horizontal Screen: Horizontal screen is parallel to the ground and make elliptical movements. As the holes are wider, the desired size of material is obtained better and the efficiency from the screening system increases.
What is Dewatering Screen?
The dewatering screen is the equipment used to separate sand from water in applications that require washing. This type of screen drains water after washing sand and has a linear movement via vibration motors.
The dewatering screen makes the vibration movement by means of two vibration motors moving in opposite directions. While water is drained through the holes, oversize rocks are transferred to the discharge system. Dewatering screen has higher G force compared to other types of screens and generally have a working cycle of 1,000 to 1,500 per minute.
Where to Use the Vibrating Screen?
Vibrating screen is a machine used to separate mines and stones by their size in order to produce the pure product. Sand as a pure product is commonly desired to be obtained because it has various usage area in several sectors and the coarseness of the sand used in each area is different. Therefore, it has an important part in stone crushing and screening plants. The areas where vibrating screens are used are given as follows:
– Production of stones and metals in different sizes
– Draining the material to be purified from water with a dewatering screen
– Removal of unwanted wastes such as plants in the product
Polyurethane Vibrating Screen
Polyurethane is a polymer composed of a chain of organic units joined by carbamate links. It has been used in many sectors recently since its flexibility and durability. And vibrating screen is one of its usage areas with a polyurethane grill. The polyurethan structure effectively reduces the noise and increases the effectiveness of stone screening and spreading processes. Polyurethane surface erodes little and maintains its durability despite intensive use. It is long-lasting. It is also able to separate gravel, stone, sand and mines both dry and wet.
