Introduction to Screening Equipment: A Comprehensive Guide

vibrating machine

1.What is Screening Equipment?

A rotary vibrating screen is a machine used to separate one material from another during the screening process. Can be applied to raw materials being refined into finer grades to produce end products that can be used in different industries and applications. The screening equipment can work independently, and can also be used in conjunction with a pulverizer and a conveyor to form a complete set of equipment, so that the material processing process is seamlessly connected.

2.How Does Screening Equipment Work?

Screening equipment machines can run on flat surfaces, which is more suitable for circular vibrating screens or inclined, which are usually used with rectangular units. These rectangular or circular machines, like circular screens, are powered by single or dual motors that generate high energy vibrations that cause particle separation and discharge of oversized and undersized material to collection containers or back into the manufacturing process of ports, sort of like a continuous “loop”.

 

3.Which industries are screening equipment suitable for?

Usually applicable to multiple industries, including food, medicine, chemical industry, agriculture and mining, etc. Every industry has a unique use for screening equipment, and each application requires a different type of screen mesh size due to their versatility and ability to screen down to micron-scale fineness on an industrial scale. For example, in spices in the food industry and powders in the pharmaceutical industry, etc., including the removal of impurities from liquids.

4.How Often Do Screens Need to Be Replaced?

How often screens need to be replaced depends on the industry and the type of material being processed on the machine. For example, if you screen corrosive materials on a daily basis, you will need to replace your screens more often than in an industry that handles such corrosive materials differently. Our engineers can help you recommend screen replacement times based on the material you’re processing on your screen, so you don’t have to worry about screen damage!

Air cooling vibrating screen for PVC granules

air cooling linear sieve

Problems we meet

Plastic granule manufacturers use plastic extruders in the production process, and the produced granules are melted to form various plastic parts needed in life.

 

Among them, when the plastic particles come out of the plastic extruder, the temperature is very high, reaching 110 degrees, and the particle size is uneven. For the back-end operation, it needs to be screened to remove unnecessary fragments and cool down the plastic particles.

What we did to

For this reason, we have specially developed an air-cooled linear screen. The linear vibrating screen is composed of two layers of perforated sieve plates (according to the particle size required by the customer, sieve plates and screens with different apertures can be installed, connected to the air cooler, and the plastic particles driven by the vibration force generated by the vibration motor, it moves forward in a straight line.

 

The cold air enters from the bottom and passes through the screen. The airflow acts on the material. While screening, the material is cooled and the material is divided into three parts. The finished material at 50-55 degrees is discharged from the middle outlet, and then cooled to room temperature naturally, and then goes to a production process.
