Product Description


The high pressure sieve basket, also known as the pressure sieve roller, is mainly used in the pressure sieve equipment to screen and separate the material before feeding. According to the screening direction of the material in the sieve cylinder, it can be divided into internal flow pressure sieve and external pressure sieve.

The pressure screen drum is an essential and important pulping screening equipment in the pulping process, so the quality of the screen drum directly determines the quality of the pulp screening, and the design, material and manufacturing process of the screen drum directly affect the fineness and efficiency of the screening.

The screen drum can remove coarse impurities and unqualified fibers in the pulp through the fine screen slit design, thereby improving the purity and uniformity of the pulp. This is essential to improve the quality and performance of the paper.
A high quality screen drum reduces energy consumption during the screening process and reduces pulp waste due to incomplete screening. This helps to reduce production costs and improve economic efficiency.


Application and Features



The screen drum is the core part of the pressure screen. Through its fine screen joint design, it can remove the coarse impurities and unqualified fibers in the pulp, so as to improve the purity and uniformity of the pulp.

The pressure screen drum can effectively protect the subsequent production equipment, avoid coarse impurities into the equipment to cause damage, and ensure the stable operation of the production line. In addition, the screening efficiency of the screen drum directly affects the production speed of the pulp, and the efficient and reliable screen drum can ensure the continuous supply of pulp and improve production efficiency.


The pressure screen drum has the advantages of high screening efficiency, long service life, and is not easy to clog.

Because the material enters the screen at a higher pressure along the tangent line, the qualified material can quickly pass through the screen drum and achieve efficient screening by centrifugal force. At the same time, the screen drum is made of corrosion-resistant and wear-resistant materials, which can resist the impact and wear of impurities in the slurry and extend the service life.

In addition, the design of the screen drum also considers the anti-clogging function to avoid the high-density accumulation of sediment and ensure the smooth screening.

Inward flow sieve basket and outward flow sieve basket.
Mainly used for filtration and concentration of fiber suspensions.

1. High screening efficiency: Because the material enters the screen at a higher pressure along the tangent line, the qualified material relies on the pressure difference to quickly pass the screen drum.
2. Long screen drum service life: Screen drum is usually made of stainless steel, corrosion resistance, wear resistance, with longer service life.
3. Not easy to block: the material is uniformly screened from top to bottom, and the V-shaped opening gap ensures the opening area of the screen drum and no obstruction, and avoids the high-density accumulation of sediment.
4. Low maintenance cost: The spindle adopts advanced mechanical sealing system, which is not easy to damage and reduces maintenance costs.




Drilled sieve basket

The pressure sieve basket is a commonly used equipment in the paper industry, which is mainly used for the screening and separation of fibers to effectively remove impurities in the slurry and ensure the efficiency and quality of paper production. At the same time, it is also widely used in chemical, food, medicine and other industries, for the screening and grading of fine materials.

The sieve basket is an important part of the pressure sieve, and its working principle is mainly to filter and separate the slurry through the sieve hole. Under the action of pressure, the slurry passes through the sieve hole of the sieve basket, and the impurities are blocked outside the sieve basket, so as to achieve the purification of the slurry. The sieve size of the sieve basket can be adjusted according to the need to adapt to the screening needs of different sizes.

Common sieve basket materials include stainless steel, carbon steel, etc. These materials have good corrosion resistance and mechanical strength, which can ensure that the sieve basket can maintain stable performance in harsh working environments. In terms of manufacturing process, the sieve hole of the sieve basket is usually used with precision punching or cutting technology to ensure the uniformity and accuracy of the sieve.


Microporous screen basket

Paper machinery Microporous screen basket an important role in paper making process. Its main function is to filter and screen the black liquor to remove impurities and particles, so as to achieve the purification and recovery of the black liquor.

Specifically, the black liquid first enters the upper separation chamber of the filter in the tangential direction, and then spills over the circular cofferdam and flows from the top down into the filtration zone between the filter drum and the rotary cylinder. In this process, the heavy impurities in the black liquor are separated under the action of centrifugal force, settled in the trap, and periodically discharged from the fallout discharge pipe.
