Stainless Steel Johnson Wedge Wire Screen Water Well Johnson Screen For Mining
Stainless steel Johnson wedge wire screen
Stainless steel Johnson wedge wire screen, , also known as slot screen, is an industrial screen developed by Johnson company. It is composed of special-shaped metal wires and support rods of different shapes. It is continuously welded by a specially designed resistance welding machine.
The Shape of the stainless steel Johnson wedge wire screen
The stainless steel Johnson wedge wire screen can be made into flat plate, cylindrical, semi-circular, fan-shaped and other shapes
The special-shaped wire can be set in a vertical bar or a circular shape.

The structure of the stainless steel johnson wedge wire screen
In the past, the metal wire meshscreen woven by metal wires was widely used in industry. Due to the large contact area between solid particles (catalyst, molecular sieve and various filter materials) and the mesh, the particles are easy to block and get stuck in the square holes of the metal wire mesh screen, resulting in increased pressure drop, which makes the device unable to operate and difficult to maintain. However, the Johnson screen and solid particles are only in contact at two points, so it is not easy to block and get stuck

Advantage of the Stainless steel wedge Johson wire screen
Johnson screen has a large opening range and a high opening rate.
The Johnson screen shaped wire is welded to each intersection of the support rod, so the accuracy is high,
Johnson screen is welded by fully automatic machinery with accurate gap.
There are only two points of contact between the continuous gap of Johnson screen and solid particles, which is not easy to block.
