MEKA grizzly feeders come in many sizes to balance demands for capacity, impact resistance, weight and installation dimensions.
They provide high production and long service life in a wide range of rigorous applications.
The dual unbalanced electric motor drive makes a simple stepless feed rate adjustment possible using a frequency converter

*At specified inclination and for material weighing 1.6 t/m³ or 100 lbs/ft³. Capacity values are indicative only and depend not only on feeder size but also on feeder inclination, feed gradation, etc.
Grizzly feeders produce a linear motion in their pan and grizzly sections and are used in the primary feeding stage for the simultaneous performance of feeding and separation processes.
The grizzly opening of the feeder is selected according to the feed curve and closed side setting of the crusher to be fed . As a result, material smaller than the crusher setting is prevented from entering the crusher. The dirty material in the feed bypasses the crusher and is fed to a screen to be discarded as waste and the remaining clean material is fed to the post-crusher process.
Although it is possible to install grizzly feeders inclined, horizontal installation is widely preferred for separation efficiency. If an increase in capacity is needed, the installation angle can be increased by several degrees without loss of separation efficiency.
