The Impact of Screen Surface Size on Vibrating Screen Capacity

Date: 2025-09-19     From: Longding     Author: admin

Increasing the screen surface size can increase the vibrating screen’s throughput, but the specific increase depends on a comprehensive consideration of factors such as screen width, length, material particle size, mesh size, and motor excitation force. Generally speaking, a wider screen surface increases the throughput. A longer screen surface length improves screening efficiency. The optimal screen surface size ratio is typically 2 to 3 length to width.

The factors influencing vibrating screen capacity

1. Screen Width and Processing Capacity

For a given material production rate, a larger screen width results in a thinner material layer, which improves screening efficiency and throughput. Simply put, the wider the linear vibrating screen, the higher the output.

2. Screen Length and Processing Capacity

A larger screen length increases screening time. Reducing the material layer thickness and increasing screening time both improve screening efficiency.

However, if the screen is too long and not wide enough, the material layer thickness increases, which in turn reduces feed rate and screening efficiency.

3. Screen Surface Size Ratio

Typically, the screen length to width ratio is 2-3 to achieve a balance between screening efficiency and throughput.

4. Material Particle Size and Screen Hole Size

Material particle size must be strictly within the equipment’s technical specifications. Excessive variations in particle size index will affect product quality and processing capacity.

The probability of material passing through the screen during screening is affected by the relative size of the material particle size and the screen hole size.

5. Motor Excitation Force

Excitation force is the primary factor affecting vibrating screen productivity. Increasing excitation force leads to a rapid increase in productivity and a decrease in clogging rate.
