How effective is a vibrating screen?

A vibrating screen, also known as a sieve or a separator, is a mechanical device used to separate materials by particle size through the vibration and movement of the screen surface. The effectiveness of a vibrating screen depends on several factors, including the type of material being processed, the amplitude and frequency of the vibrations, the angle of inclination of the screen, and the design of the screen itself.

How the effectiveness of a vibrating screen

Double banana sieve

Particle Separation

The primary purpose of a vibrating screen is to separate particles based on their size. The screen’s mesh or opening size determines the size of particles that can pass through. Larger particles are retained on the screen surface and are referred to as oversize, while smaller particles pass through and are referred to as undersize. The effectiveness of the screen is determined by how accurately it separates these particles according to size.

Screening Efficiency

The screening efficiency of a vibrating screen refers to the percentage of undersize particles in the feed material that actually pass through the screen and are collected as product. Higher screening efficiency indicates that the screen is effectively separating particles of the desired size. Factors such as vibration amplitude, frequency, and screen inclination play a role in determining screening efficiency.

Capacity

The capacity of a vibrating screen is the amount of material it can process in a given time period. An effective vibrating screen should be able to handle the desired capacity without causing excessive wear, blinding of the screen surface, or other operational issues.

Screen Blinding

Screen blinding occurs when particles become trapped in the openings of the screen, reducing the effective open area and diminishing the screening efficiency. This can happen due to factors like moisture, fine particles, and high feed rates. Effective screen designs incorporate features to minimize blinding, such as anti-blinding devices and screen surface treatments.

What is the working principle of horizontal screen?

The working principle of a horizontal screen, also known as a horizontal vibrating screen, revolves around the concept of mechanical vibration and motion to separate, classify, and convey materials. Horizontal screens are commonly used in industries such as mining, construction, aggregate processing, and more for tasks like sizing, dewatering, and scalping of various materials.

The working principle of a horizontal screen:

High Frequency Dehydration Vibrating Screen

1. Structure: A horizontal screen consists of a rectangular or slightly inclined box-like structure called a “deck.” The deck is mounted on a frame and is typically equipped with multiple screen layers or decks stacked on top of each other.

2. Vibration Mechanism: Horizontal screens use a vibration mechanism to generate the necessary motion for material separation. This mechanism is usually provided by one or more vibrators mounted on the sides of the screen. These vibrators generate oscillating or circular vibrations that cause the screen deck and the material on it to vibrate.

3. Material Loading: The material to be screened is fed onto the screen deck from the top or one end. The material spreads across the width of the deck, forming a thin layer.

4. Separation: As the screen deck vibrates, the material experiences a combination of vertical and horizontal motions. The vertical component lifts the material, allowing smaller particles to pass through the gaps in the screen mesh or openings. The horizontal motion propels the material forward along the deck.

Linear Vibrating Screen

5. Sizing and Classification: Depending on the size of the openings in the screen mesh, particles that are smaller than the openings will fall through and be collected as undersize material, while particles larger than the openings will remain on the screen and be collected as oversize material. This process classifies the material into different size fractions.

6. Decks and Multiple Layers: Horizontal screens often have multiple decks or layers of screens stacked on top of each other. Each deck may have different screen mesh sizes to further refine the material into different size categories.

What are the parts of the vibrating screen exciter?

The vibrating screen exciter is a critical component of the equipment, responsible for generating the vibration that drives the motion of the screen deck. It typically consists of several main parts that work together to create the desired vibratory motion. The specific design and configuration of these parts can vary depending on the manufacturer and the type of vibrating screen.

Vibrating screen exciter parts

BE1800

Vibration Motor: The vibration motor is an essential part of the exciter and provides the primary source of vibration. It is an electric motor that generates the necessary rotary motion to drive the eccentric weights or shafts.

Eccentric Weights: Eccentric weights are attached to the vibration motor’s shaft. These weights are offset from the center of the shaft, creating an unbalanced force when the motor rotates. The unbalanced force generates vibratory motion and vibration amplitude.

Shaft: The shaft is a key structural component that connects the vibration motor to the screen frame. It transmits the rotary motion from the motor to the screen deck, causing it to vibrate.

Bearings: Bearings support the shaft and allow it to rotate smoothly. Properly functioning bearings are crucial for the smooth and reliable operation of the exciter.

DE20A

Housings and Seals: Housings enclose the bearings and other internal components, providing protection and support. Seals help to prevent contaminants from entering the bearings and ensure their longevity.

Mounting Structure: The mounting structure connects the exciter to the screen frame. It must be sturdy and well-designed to withstand the forces generated during operation.

What is the working principle of double deck screen?

A double-deck screen, also known as a double-deck vibrating screen, is a piece of equipment used in the mineral processing and aggregate industries to separate and size particles or materials into different grades or fractions. The working principle of a double-deck screen involves the use of multiple decks, each with different-sized screens, to efficiently separate the material into two or more fractions based on their particle size.

The working principle of a double-deck screen

Double banana sieve

Material Feeding

The material to be screened is fed onto the top deck of the double-deck screen. This can be done using a conveyor belt, a chute, or other feeding mechanisms.

Screening Surfaces

A double-deck screen consists of two decks or levels, each with a different-sized screen opening. The top deck usually has larger openings or mesh size, while the bottom deck has smaller openings.

Vibrating Motion

The screen decks are mounted on a frame and are vibrated using a motor or vibrating mechanism. This vibration causes the material to move and spread across the surface of each deck.

Particle Separation

As the material spreads across the top deck, particles that are smaller than the openings in the top deck pass through and fall onto the bottom deck. The larger particles that cannot pass through the openings in the top deck continue moving towards the end of the screen.

What are the operating steps of the high pressure grinding rolls

High pressure grinding rolls (HPGR) are a type of comminution equipment used in the mining and minerals processing industry. They are designed to reduce the size of particles by compressing and crushing them between two counter-rotating rolls with a small gap between them. HPGRs are typically used for processing hard and abrasive ores.

The operation steps of HPGRs

high-pressure grinding rolls

Feed Material Introduction: The ore or material to be processed is introduced into the gap between the two rolls. This feed material can vary widely in terms of size, hardness, and moisture content.

Comminution: As the rolls rotate, they exert high pressure on the feed material. This pressure causes the particles to break and deform, leading to the reduction in particle size. The material is primarily crushed through a combination of compression and interparticle breakage.

Particle Bed Formation: The crushed material forms a bed between the rolls. The particle bed acts as a cushion that helps to distribute the pressure more evenly and prevent excessive wear on the rolls.

Discharge: Once the material has been sufficiently comminuted, it exits the HPGR through the gap between the rolls. The product, often referred to as the “flakes,” “chips,” or “cakes,” typically has a more uniform particle size distribution compared to traditional grinding methods.
