Thickening and screening for many types of products
Our DSM Screens are low maintenance, gravity-fed and suitable for mineral processing, chemical, food, pulp and paper.
Designed with your operation in mind, Our DSM Screens are a curved concave wedge bar type of stationary screen made to be rugged, compact, efficient and easy to operate.
With no moving parts, these screens require minimal maintenance. Our full line of gravity-fed DSM Screens are available in the following types: 45°, 60°, 120°, 270°, 300°, and rapifine. They are often used in the following industries: mineral processing, chemical, food and pulp and paper.
Each of these screen sizes has been tailored for a variety of process applications. For example, the 45° DSM Screen is best suited for thickening and screening, whereas the 120° type DSM Screen is capable of thickening pulp, recovering fibre, or separating fibre as small as 100 microns in length from a water suspension. It is very compact and requires minimal maintenance.
The DSM's unique screen plate is made of wedge bars forming a bowed surface with horizontal slots between the bars. Normal slot width is 100 or 150 microns.
The flow to be screened is fed through a low-pressure nozzle which distributes the flow tangentially over the full screen width by means of an adjustable slice that optimises feed velocity. As the suspension flows along the screen plate, thin layers of water are "sliced off" by the screen bars and pass through the slots together with fine particles.
Goodbye high-maintenance: a DSM Screen made to save space and money
Designed with you in mind, our DSM Screens are meant to be not only compact, rugged, and durable, but also extremely efficient and easy to use. Additionally, they are low cost and low maintenance. Because our DSM Screens have no moving parts, they require very little maintenance. This also makes them lower in cost.
Since our DSM Screens are compact, they'll leave ample space for other parts and machines. Their relatively low cost means you'll have more funds to spend on the bigger-picture elements of your operation.
DSM Screens: your permanent, low-maintenance screening solution In your search for the most reliable and highest quality DSM Screens, there are a number of features that are high on your priority list.
You want a supplier that offers screens in many types so that you can find the right fit for your machine and use case. You demand a solution that is low maintenance and compact. These are just some of the features that come standard with our DSM Screens. Here is a larger list of all the features of our DSM Screens:
When you require the most effective method to remove solids, trust our ClearBlu wedge wire waterfall systems. View five reasons our products are the best.
GWWSL manufacturers wedge wire waterfall screens as a highly efficient and cost-effective alternative to other solids removal systems. A number of factors make these wedge wire screens an excellent choice.
This wedge wire screen is designed for flows from 0 to 100 GPM for hydro screens. GWWSL screens are unique in that they have a 60-degree slope and are self-cleaning in most applications. They have no moving parts. The concept is simple: run the wastewater over a weir and down over a wedge wire screen. The solids are pushed off the screen and the liquids pass through the wedge wire.
wedge wire screen
There are several important factors in selecting a good waterfall filter. First, the spacing between the wedge wire bars can vary. Second, the top of the wedge wire is flat (wedge wire is made of flattened tubing) and the tops should be canted slightly so that they trap the water. Third, there needs to be sufficient runway at the top so that the water can gain velocity. This is accomplished by placing a smooth section of stainless just below the weir at the top. Fourth, the slope of the wedge wire needs to be steep. This is counterintuitive. It would seem that you would want a low slope to slow the water. Instead, you want a steep slope so that you don't build up solids on the wedge wire screen. Water is heavy and will pass through a steep screen. Manufacturer: MiTM

The Model 2 waterfall screen has six square feet of wedge wire screen surface and is half the size of the Model 3. This wedge wire screen effectively removes solid particles from a waste stream. Like the other types, this model uses very little energy and requires only a minimum amount of maintenance. It's ideal for many different applications including agriculture and manufacturing.
This unit will handle flows up to 400 gallons per minute. It has a 1 MM wedge wire screen. The key to hydro screens is having the correct angle on the screen and having enough runway for the water so that it gains sufficient velocity over the wedge wire screen. This seems counterintuitive. Most manufacturers lower the slope and try to slow the water. This creates clogging and water bypass.
Our unit has a 60-degree slope. The screen is 48" wide and 36" long. The unit is stainless steel.
Waterfall screens are ideal for effectively removing fibrous and solid particles from a waste stream. An automatic self-cleaning spray bar runs on a timer to continually keep the screen free from debris buildup. These screens use very little energy and require very little maintenance.
Standard wedge wire is available in 0.5 mm and 1 mm spacing, but custom spacing is available. All models are available with stands in carbon or stainless steel. For solids handling, self-dumping dewatering hoppers from ¼ yard to 5 yards in size are available. Dewatering screens are stainless steel mesh behind stainless steel perf plate with ½" openings. The hopper is carbon steel with an option to come painted or galvanized.
