Vibrating Screen
Vibrating Screens are grading equipment that work by vibrating and moving the input particles along the screen, dividing them into groups of the same mesh.
Screen structure and frame design is especially important given the high amplitude and high frequency dynamic vibrational load that the device undergoes. The durability, behavior and also the capacity and separation precision of the screen is very important in a production line, as the screen is often considered the heart of a crushing, grading or processing line.
In order to efficiently utilize the screening surface and grade tons of input per hour, screens are built in different lengths, widths and with multiple screen desks.
The vibration system incorporated in the screens consists of one or two moment axes and adjustable weights that are installed on heavy-duty, moisture and dust resistant bearings that transfer the circular vibrations of the frame to particular spiral springs.
grizzly screens
Most often used for pre-screening, the typical feed materials that require grizzly screens versus the typical vibrating screen are very coarse aggregates.
Able to handle both wet and dry materials, grizzly screens often handle materials such as minerals, ore, blasted or ripped rock, gypsum, foundry materials and large stone. Grizzly screens can offer multiple sizing decks on a single unit as well as side plates that provide additional height to ensure that large materials stay on the screen.
Grizzly screens can provide either linear or circular motion and each type offers its own advantages. Linear motion grizzly screens work best for scalping ahead of primary cone crushers in mining applications, while circular motion grizzly screens for heavy duty medium to fine pre or post-screening.
Primarily used for the heavy duty screening of undersized materials in bulk material handling applications, the most common industries that utilize grizzly screens include mining, construction, foundry, recycling and industrial.
