Polyester granules, as an important raw material for synthetic fibers and plastic products, have certain friction and adhesion. They are usually granular with smooth surface, but they may also contain a certain proportion of fine powder, irregular agglomerates and impurities such as strip woven bag fragments due to different production processes or storage conditions. Therefore, polyester granule vibrating screens must have classification and impurity removal during the production process. We will recommend two vibrating screens for you below to ensure the smooth and efficient screening process.

Screening requirements

Purpose: Polyester granules classification and impurity removal
Recommended equipment: Linear vibrating screen and rotary vibrating screen
Screen: 3mm
Output: 2-4.5T/h

Considerations for selecting screening equipment

Based on the above material analysis, how to choose a suitable Polyester Granules vibrating screen needs to consider the following three factors:

Screening equipment selection: Polyester granule screening equipment should have a strong vibration force that can fully stimulate the jumping and tumbling of particles and improve screening efficiency.
Screen: Wear-resistant, corrosion-resistant and non-clogging screen materials such as stainless steel perforated plates or polyurethane screens are used.
Multi-layer grading: It can be equipped with multiple layers of screens to achieve multi-level screening
Easy to maintain and clean: During the screening process, if the screen is blocked or worn, it can be easily replaced or repaired.
Environmental protection: Low noise and vibration during operation, in line with environmental protection requirements.

Solutions

Solution 1: Rotary vibrating screen SY-1600

Stainless steel perforated plates or polyurethane screens, output: 2-3ton/h, relatively low price, suitable for small-scale production needs.

Features

Efficient screening capacity: The rotary vibrating screen adopts the three-dimensional power principle to make the material jump forward on the screen, effectively avoiding the material from clogging the screen holes, and is particularly suitable for processing materials containing impurities or easy to agglomerate. Its high-frequency vibration can quickly separate the strip woven bag debris and agglomerated large particles, improving the screening efficiency.
Anti-blocking hole design: The screen of the rotary vibrating screen can adopt a specially designed anti-blocking hole mesh or elastic screen, which effectively reduces the adhesion and blockage of the material during the screening process. It is suitable for fine or easily entangled impurities and can maintain a high pass rate.
Flexible adjustment: The amplitude and vibration frequency of the rotary vibrating screen can be flexibly adjusted according to the characteristics of the material to achieve the best screening effect.

Solution 2: Linear vibrating screen SYZ-1550

Stainless steel perforated plate screen, output: 5-7ton/h, the price is 2-3 times more expensive than the rotary vibrating screen, suitable for large-scale production lines.

Features

Efficient screening: The linear vibrating screen is driven by two reverse motors of the same frequency, so that the material jumps linearly on the screen surface, thereby quickly separating impurities, agglomerated large particles and particles of different particle sizes of polyester particles.
Not easy to block: The screen structure of the linear vibrating screen is special, not easy to block, and can maintain a long-term stable screening effect.
Strong adaptability: The linear vibrating screen can perform multi-stage screening according to production needs. The screening process is not affected by factors such as material humidity and viscosity, and can operate stably and reliably.

The vibrating screen solution for Polyester Granules needs to comprehensively consider factors such as particle characteristics, screening efficiency, and screening accuracy. By selecting appropriate screening equipment, customizing suitable screens, adjusting vibration parameters, and strengthening cleaning and maintenance, efficient and accurate screening of polyester particles can be achieved, providing high-quality raw material guarantees for downstream processing.
