Grizzly Screen

Grizzly screens (MGS) are built with extra heavy-duty applications in mind. They are circular motion inclined screens with two decks, fitted with grizzly on the top deck, and wire mesh on the bottom deck. These screens are heavy and have more powerful motors and drives than a regular circular motion screen. They have been designed for screening immediately after a primary crushing operation, allowing a maximum feed size of up to 400 mm.

Applications

MGS Grizzly screens are widely used before the secondary crushing stage, where unwanted material needs to be thrown out as waste or where coarse fractions should be taken out as product. Additionally the facility for bypassing fines ahead of the secondary crusher maximizes the throughput at this stage.

Why MEKA Grizzly Screen?
  • Massive Durability

Excel in extreme and abrasive conditions with unparalled ruggedness and resistance to wear

  • Versatality

Fitted with grizzly bars on the top deck, can handle big, tough loads with ease

  • Maximum efficiency

Adjustable counterweights in drive unit to assure proper screen stroke for each application.

  • No weld side plates

MEKA's "no weld" policy on screen side plates eliminates the possibility of stress concentrations in heat affected zones.

What is Grizzly Screen?

Grizzly screens are heavy duty inclined circular motion two decks screens. Top deck equipped with grizzly and bottom deck with wire mesh.

Types of Grizzly Screen
Grizzly screens are primary type 2 deck screens with circular motion.
How Does Grizzly Screen Work?

Generally, the top deck of the screen feeds the material to the downstream crusher , the material passing through the bottom deck is sent to the stockpile as waste or other purposes while the material between the two decks by-pass the crusher.

Advantages of Using Grizzly Screen

By removing unwanted material and bypassing the downstream crusher, productivity is increased and energy consumption is reduced: More plant capacity , less wear, less energy consumption in the downstream crusher.

Grizzly Screen Processes Applications
It is used in aggregate, mining, coal and many other primary applications to scalp and screen materials with a maximum feed size of up to 400 mm.
