Sieve Bend Screen, DSM Screen

Johnson bend screen

Solutions to the problems of industrial dewatering, sizing, and wastewater treatment.
Johnson screen static sieve bend screen is widely used in the industry. when the material flows on the curved surface, it exerts more force on the screen than on the flat wedge wire screen, compared with flat-screen, its screening performance is more excellent.

Application: Mining and mineral processing industries, pulp and paper, dewatering, chemical, food, starch (fiber removal), cement,suger mill screen, sewage treatment, textile mills, etc.
Customized angle, arc length, radius, and other non-standard screens.

45° DSM Screen – Commonly used for thickening and screening.
120° DSM Screen – Pulp thickening, recovery, and separation of fibers.
800 mm arc length – Media recovery. Use at height limit.
1600 mm arc length – Made for maximum drainage.
1200 mm arc length – Maximum drainage, but the height does not allow 1600 mm.

We can customize suitable products according to the actual use.

The arc angle of 45°, 60°, and 90° are often adopted for self flow DSM screen, used in coal preparation plant and concentrator.

The pressure type DSM screen, which usually adopts the arc of 180° and 270°, is used in the grading operation of the grinding process in the cement industry. 

Because of the great discharge capacity of the sieve bend screen, many coal preparation plants often use it for pre-dewatering before the dewatering screen, and the gap between the screens is generally 3-6 times larger than that of the dewatering screen in the next process, but the maximum slot should not exceed 3 mm.

The width of the sieve bend screen shall be 150-200mm smaller than that of the dewatering screen in the next process. Arc screen can also be used in series as required.

We have accumulated rich production experience and can give professional suggestions according to the specific use of customers.

Wedge Wire Screen Specification

Wedge wire screen surface treatment
Generally, the finished product will be polished, so that the product will appear bright.
With China’s emphasis on environmental protection, this treatment process has been banned. We independently developed a new treatment process to physically treat the product surface, which not only has a smooth appearance but also greatly improves the service life of the product.
