Radial Load Capacity

Dynamic Load Rating (C): The dynamic load rating of a bearing is the calculated constant radial load (in Newtons or Pounds) that a group of identical bearings can endure for a rating life of one million revolutions. It is an important factor in determining the bearing’s ability to handle radial loads during normal operation.

Static Load Rating (Co): The static load rating represents the maximum radial load that a bearing can support without permanent deformation. This is important when analyzing applications with static or slowly changing radial loads.

Axial Load Capacity

Dynamic Axial Load Rating (Ca): Similar to the dynamic radial load rating, the dynamic axial load rating is the calculated constant axial load that a group of identical bearings can endure for a rating life of one million revolutions.

Static Axial Load Rating (Coa): The static axial load rating represents the maximum axial load that a bearing can support without permanent deformation.

Combined Radial and Axial Loads

Equivalent Radial Load (P): In applications where both radial and axial loads are present, the equivalent radial load is calculated to simplify the load analysis. It allows for the combination of radial and axial loads into a single radial load value.

Equivalent Dynamic Radial Load (Pdynamic): This is the calculated equivalent radial load when axial and radial loads are combined. It is used to determine the bearing life when both types of loads are present.

Equivalent Static Radial Load (Pstatic): Similar to the equivalent dynamic radial load, this is the calculated equivalent radial load when both axial and radial loads are present, but in a static (non-rotating) condition.

The capacity of a vibrating screen is a measure of the amount of material that can be processed or screened in a given time period. It is usually expressed as tons per hour (tph) or cubic meters per hour (m³/h), depending on the unit of measurement used. The capacity of a vibrating screen depends on several factors, including:

Screen Size and Surface Area: Larger screens and greater surface areas can handle more material.

Screen Deck Configuration: The number of decks on a vibrating screen can affect its capacity. Multiple decks allow for the sorting of different particle sizes.

Screen Motion: The type of motion of the vibrating screen, such as linear, circular, or elliptical, can impact its capacity. Different motions are suitable for different types of applications.

Screen Slope: The angle of the screen deck also plays a role. Steeper slopes generally allow for better material separation but can reduce capacity.

Material Characteristics: The type, size, and characteristics of the material being screened influence the capacity. For example, wet or sticky materials may require a different type of screen or additional equipment for effective screening.

Vibration Frequency and Amplitude: The frequency (cycles per minute) and amplitude (the height of the vibrating motion) can be adjusted to optimize the screening process for different materials.

Feed Rate: The rate at which material is fed onto the screen affects the screening capacity. Proper feed rates help ensure optimal performance.

Screening Efficiency: The efficiency of the screening process also affects capacity. Higher efficiency means more effective screening and potentially higher throughput.

Vibrating screen capacity calculation

Arc Vibrating Screen

The capacity of a vibrating screen is typically represented by the throughput or the flow rate of material through the screen. The capacity calculation depends on various factors, including the screen dimensions, screen inclination, and the characteristics of the material being screened. Here’s a general approach to calculating the capacity of a vibrating screen:

1. Basic Formula:

The basic formula for calculating the capacity of a vibrating screen is:

Where:

  •  is the capacity (throughput) in tons per hour.
  •  is the effective screening area (in square feet).
  •  is the percentage of material in the feed to the screen that is smaller than the screen opening size.
  •  is the basic capacity of the screen in tons per hour per square foot.
  •  is the efficiency factor, which is typically in the range of 90-95%.

linear vibrating screen is a type of vibrating screen machine used for screening and grading materials in various industries. It employs a linear motion to convey materials along the vibrating surface, providing efficient and effective screening of granular and bulk materials. Here’s a detailed introduction to the linear vibrating screen.

Key Components of a Linear Vibrating Screen

Single layer horizontal sieve

Screen Surface

The screen surface is the primary component where the material separation takes place. It is typically made of wire mesh or perforated plates with specific opening sizes to allow particles of desired sizes to pass through.

Vibrator Motors

The linear vibrating screen is equipped with one or multiple vibrator motors that generate the vibration required for material movement. These motors are mounted on the screen frame and provide the necessary linear vibration.

Screen Frame

The screen frame supports the screen surface and vibrator motors. It is designed to withstand the dynamic forces generated during the screening process. The frame may be constructed from steel or other materials depending on the application.

Springs or Rubber Mounts

To isolate the vibrations generated by the vibrator motors, linear vibrating screens often use springs or rubber mounts. These components absorb and dampen the vibrations, preventing excessive transmission to the supporting structure.

Feed Inlet and Discharge Chutes

The linear vibrating screen has designated areas for material entry (feed inlet) and exit (discharge chute). The material is usually fed onto the screen surface through the feed inlet, and the screened material exits through the discharge chute.

Drive Unit

The drive unit includes the motor(s), which generate the linear vibration, and may also include other components like belts or gears depending on the specific design of the linear vibrating screen.

Operating Principle

Linear Vibrating Screen

Vibration Generation

The vibrator motors generate linear vibrations that cause the screen surface to move along a straight line. This motion helps convey and separate the material based on size.

Material Feed

Material is introduced onto the vibrating screen surface through the feed inlet. The linear motion of the screen surface moves the material along the length of the screen.

Screening Process

As the material travels along the vibrating surface, particles that are smaller than the openings in the screen pass through, while larger particles are retained. This process effectively separates materials into different size fractions.

It consists of a screen mesh, which is a surface with openings of specific sizes, through which materials pass when subjected to vibration. Vibrating screens find applications in various industries, including mining, construction, agriculture, and recycling.

Components of a Vibrating Screen

Screen Mesh:

The screen mesh is a critical component with openings that determine the size of particles passing through. Different types of screen meshes, such as woven wire mesh or perforated plates, may be used based on the application.

Vibrator Motors:

Vibrating screens are equipped with one or more vibrator motors that generate the vibratory motion. These motors are mounted on the sides or underneath the screen deck.

Screen Deck:

The screen deck is the surface on which the material is placed for screening. It can have one or multiple layers, each with a different mesh size.

Support Structure:

The support structure provides stability and ensures proper alignment of the vibrating screen components. It may include a frame, springs, and other structural elements.

Drive Unit:

The drive unit is responsible for generating the necessary vibration to move the screen. It typically includes an electric motor, an eccentric shaft, and a set of gears.

Working Principle

The vibrator motors generate vibratory motion, causing the screen deck to vibrate. This vibration moves the material along the screen surface and separates particles based on size or other characteristics. The inclination and amplitude of the vibrating screen can be adjusted to optimize the screening process for specific applications.

High Frequency Dehydration Vibrating Screen

Screening Area Calculation:

  • The screening area is the total available surface area of a screening deck.
  • Calculate the screening area by multiplying the length of the screen (L) by the width of the screen (W).

Deck Surface Opening:

The size of the openings in the screening surface affects the efficiency of the screening process.

Specify the desired opening size or use the average particle size of the material being screened.

Vibration Amplitude:

Vibration amplitude is the measure of the amount of vibrational movement the screen deck undergoes during operation.

It is typically expressed in millimeters (mm) or inches (in).

The amplitude can be determined based on the type of vibrating screen and the material being processed.

LYLKWE spindle bearings are universal bearings, and the bearing rings have the same width. The protrusions on both sides of the bearing are the same size.

Advantages of universal matched bearings

Individual bearings can be installed in any bearing arrangement required, such as X-shaped, O-shaped or tandem arrangements with rigid or elastic preload, or can be combined in different bearing groups.

In a tandem bearing arrangement, in order to ensure that the bearings carry a consistent load, the bearings being paired have the same dimensional deviation between the inner and outer diameters.

In a rigidly adjusted O-ring arrangement, grouping detection of interference between the shaft and bearing bore diameters or housing and bearing outside diameters can help control changes in actual preload after the bearing is installed.

Bearings can be arranged according to the direction of the arrow on the outer ring surface.

Universal matching bearing set

The universal matched bearing set is composed of universal matched bearings with the same bearing inner diameter deviation and the same bearing outer diameter deviation.

The dimensional deviation represents the actual size code, which is the deviation value of the inner diameter or outer diameter marked on the bearing ring.

The universal matched bearing set is composed of multiple bearings with the same technical quality and the same bearing inner diameter deviation and bearing outer diameter deviation.

Bearing group identification

The first letter indicates the number of paired bearings:

D=2 bearings (double)

T=3 bearing (triple)

Q=4 bearings (quadruple).

“U” means “universal pairing” such as DU. After these letters, there is an indication of the preload level, such as DUL, where “L” means light preload.

Universal bearing sets can be installed in any required bearing arrangement.
