Pellet Screening Device for Drum Sludge Processing

Introduction

The drum sludge processing device is used to separate sludge from other liquids. The most common application is to collect any solid particles which are however suspended in the liquid and are unable to sediment under normal gravity. To this end, a pellet screening device (PSD) is used to remove the larger particles which are damaging the slurries or interfering with dried sludge.

Construction

The construction of the drum sludge processing Pellet Screening Device consists of a cylindrical channel along with a series of vertical slats set close together. The density and size of the slats vary according to the application and the flow rate requirement. The screen is designed such that the slats can be opened and closed efficiently, allowing the flow rate to be adjusted based on the type of particles to be separated.

Operation

Typically, sludge is pre-processed before entering the Pellet Screening Device for screening. The pre-processing stage typically involves agitating the sludge, allowing the larger chunks of debris to be broken down into smaller pieces for efficient screening. The Pellet Screening Device is then used to sieve out these pieces.

The Pellet Screening Device is activated when the slurry reaches the top of the cylindrical channel. This can be done either manually or automatically. When activated, the slats of the screen move up in synchronization with the flow rate. The upward current of the slurry causes the solid particles to be lifted while the smaller particles are left behind. As the solid debris is lifted, the water is allowed to flow through the slats. The particles that remain are then separated into different sizes according to the size of the slats. The separated particles are then collected in channels or chambers at the bottom of the PSD.

Advantages

Pellet Screening Device provides a number of advantages over traditional solids-separation systems. The most important benefits are the accuracy of size-based separation, the flexibility of adjusting the separation rate, and the improved safety and efficiency that it offers. Moreover, the pellets used in PSDs are less prone to breakage, making them more suitable for treating difficult slurries.

Conclusion

The Pellet Screening Device is an effective and efficient way to remove unwanted particles from a variety of liquid slurries. Its stainless steel construction, adjustable slats, and accuracy make it suitable for a number of applications. With its ability to quickly and accurately filtered particles of different sizes, the Pellet Screening Device is an ideal solution for industrial wastewater treatment, slurry separation, and other liquid processes.

Marvon Trommel sieve is a kind of device used in drum method slime treatment. It is applied in coal, stone, non-ferrous metal ore, rare metal ore, etc. It is popularly used for screening screening of ore or slurry.

The Marvon Trommel sieve consits of an axle device, a large taper sleeve and a supporting device. The large taper sleeve is composed of a plurality of taper sieves and a substructure for supporting the sieves. Because the taper is elastic, the individual taper sieves are properly subjected to elastic forces to ensure that the ore particles screened through are neat and uniform particle size.

The trommel sieve is generally divided into two forms of movement: rotary movement and linear movement. The motor is directly connected to the large sieve sleeve by the lower drive shaft, and the drive shaft is provided with a gear ring. When the motor is driven, the gear ring is driven, so that the large sieve sleeve rotates around the center, so it is called rotary movement.

In addition, the working surface of trommel sieve need to maintain certain inclination angle to ensure smooth ore transportation and uniform speed, otherwise it will cause jam. Generally, the working surface of the equipment should be kept at 10 ° or 15 °.

In addition, the size of the sieve hole of Marvon trommel sieve is 28-250mm, which can be used for vibrating sieve according to the size of the hulling material. At the same time, The large sieving cylinder is easy to clean and maintain, and can be positioned as required.
