Vibrating screens come in various types, each designed for specific applications and industries. Here's an overview of the common types, their functions, operating principles, and factors affecting their price and specification.
Types of Vibrating Screens
Circular Vibrating Screen
Circular vibrating screen operates in a circular motion, generated by an eccentric shaft with an unbalanced weight on its ends,
causing the screen to vibrate in a circular pattern.
Circular vibrating screens are widely used in industries such as mining, construction, chemical, and others for efficient screening and sizing of various materials. Some key advantages of circular vibrating screens include their ability to handle a wide range of materials, their high screening efficiency, and their ability to perform well even with wet and sticky materials.
Gyratory Vibrating Screen
Gyratory screen, also known as a gyratory sifter or gyratory separator, is a efficient and reliable screening equipment, particularly when dealing with difficult-to-screen materials or high-capacity requirements. It is an efficient and versatile screening machine commonly used in various industries, including food processing, chemical, pharmaceuticals, and agriculture.
gyratory screen consists of a circular screening assembly that is driven by a vibratory motor located beneath the screen surface. The motor imparts a gyratory motion to the screen assembly, causing it to vibrate in a circular path on a horizontal plane. As the material is fed onto the screen, it spreads out evenly due to the gyratory motion.
Tumbler Screen Machine
Tumbler screen machine, also known as a tumbler sieve machine or tumbler screening machine, is a specialized screening equipment designed to perform highly efficient fine particle separation. It is commonly used in industries such as pharmaceuticals, chemical, food processing, and mineral processing, where precise particle size separation is crucial.
The tumbler screen machine operates on the principle of gyratory motion, wherein the material being screened is subjected to a unique tumbling motion along with a series of gyratory vibrations. This motion allows for better dispersion of the material, preventing it from getting trapped in the screen openings and improving the screening efficiency.
Linear Vibrating Screen
Linear vibrating screen is a type of screening equipment that is commonly used in mineral processing, coal preparation, and other industrial applications to separate and size particles. It operates on the principle of vibration in a straight-line motion, causing the material to move across the screen and be classified based on its size.
Linear vibrating screens have a ability to handle large capacities of material and their simplicity in design and operation. They are efficient for classifying a wide range of materials, from fine powders to coarse particles.
High-Frequency Vibrating Screen
High-frequency vibrating screen is a type of vibrating screen that operates at a frequency higher than the standard vibrating screen. Its motor in a high-frequency vibrating screen produces rapid vibrations at a rate of 1,500 to 3,000 RPM (revolutions per minute) or even higher, ability to handle a large capacity of material and efficiently screen fine and ultra-fine particles. High-frequency vibrating screens are particularly effective in applications where traditional vibrating screens struggle to achieve the desired separation due to blinding or clogging of the screen surface.
High-frequency vibrating screens are commonly used in industries such as mineral processing, coal preparation, pharmaceuticals, and dewatering processes. They are also utilized in recycling applications to separate fine particles from the recycled materials.
Operating Principle
The vibrating screen operates on the principle of applying vibration to the screen surface, causing the material particles to move and separate based on their size and shape. The vibration is typically generated by electric motors or mechanical excitation systems. The amplitude and frequency of the vibration can be adjusted to optimize the separation process for specific materials.
Function
The primary function of vibrating screens is to separate and classify materials by size and other characteristics. This allows for efficient processing and handling of materials, improving product quality and consistency. The functions of vibrating screens include:
a. Screening and Sizing: Separating materials into different particle sizes.
b. Dewatering: Removing excess moisture from materials.
c. Sorting: Classifying materials based on specific attributes (e.g., density, shape).
d. Scalping: Removing oversized particles to protect downstream equipment or enhance process efficiency.
Price and Specification
The price and specification of vibrating screens can vary widely based on several factors:
a. Screen Type and Size: Different screen types and sizes come with varying costs.
b. Material of Construction: Screens can be made of stainless steel, carbon steel, or other materials, influencing the price.
c. Capacity and Throughput: Higher capacity screens may be more expensive.
d. Features: Additional features like dust covers, anti-blinding devices, and automation can affect the price.
e. Brand and Manufacturer: Well-known brands or specialized manufacturers may have premium-priced products.
