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.
