Grizzly Screens have been designed for the toughest applications capable of high capacity and the ability to process coarse material. These screens have a very robust design, which allow hem to operate under tough conditions (primary or secondary). They particularly perform very well when used to remove the fi nes between two crushing stages.
GRIZZLY SCREEN
HEAVY-DUTY VIBRATING SCREENS
The output material of the primary group may need to be screened in accordance with the installation plan. In these cases, standard vibrating screens may not meet the required capacity and can be disadvantageous in respect to servicing costs, but the top decks of our heavy-duty screens are equipped with grizzly or abrasion resistant perforated plates to avoid any damage caused by large-size materials. The springs on heavy-duty screens are more durable as well.
FEATURES CONTRIBUTING TO PLANT EFFICIENCY
MGS series screens are equipped with many features enabling high efficiency and ensuring various operational advantages.These advantages reduce maintenance and servicing costs, along with necessitating less downtime.
LARGE SPACE BETWEEN DECKS FOR EASY MAINTENANCE
The space between the decks of the inclined screens is designed to provide easy access during servicing. Therefore, the ti me spent replacing screen mesh is reduced, meaning less downtime.
Inclined Screens
Screening process is just as important as the crushing itself. Screens are the heart of every rock processing plant. They are used to classify materials both in different stages of the crushing process and in final product separation. Designed as a non-welded frame with adjustable vibration features for different material types and screening sizes, the inclined screens provide screening efficiency that is both high quality and dependable. Our inclined screens come in various sizes starting from 2 m² up to 16 m² and are equipped with up to four decks that can be supplied with different types of media, such as grizzly, perforated sheet, polyurethane and steel with washing options to meet the requirements of a wide range of applications.
In this way, our innovations prevent fractures that commonly occur on other screens, particularly around the drive system. Su ch fractures make the screen unusable by expanding on the side plate.
SELF-TENSIONED MOTORBASE
In MS series inclined screens, a self-tensioned motorbase is a standard feature to protect both the electric motor and drive belts against tension caused by vibrations, meaning less maintenance duration and lower costs for our customers.
HUCK-BOLTED ASSEMBLY SIDE PLATES
Screen bodies with a conventional bolted assembly create extra labour costs, increase security risks and reduce overall profitability because of the rupture of bolts caused by loosening nuts. The MS series inclined screens with huck-bolted assembly don’t require maintenance for bolts and nuts, so they also ensure workplace security.
EASY MAINTENANCE THANKS TO OUR MOVABLE FRONT CHUTE WITH SLIDER
Screen mesh is one of the most frequently replaced wearing part on inclined screens. To simplify the maintenance process and reduce downtime, we designed front chutes with sliders for inclined screens bigger than 8 m² so the f ront chute can be moved without using any lifting equipment. This provides easy access to the screening media for maintenance in just a few minutes.
MODULAR-TYPE DRIVE SYSTEM
The MS series inclined screens are equipped with a modular-type drive system for easy servicing. The two-piece drive-shaft system can be detached easily one by one, reducing servicing duration. Additionally, the cardan shaft connecting the modular shafts is more advantag eous than traditional heavier and single-piece shafts in terms of easy maintenance.

Horizontal Screens
The Horizontal Screens are a combination of quality, reliability, and performance; providing a long service life while operating under the most demanding applications. Proven oval stroke design increases production, reduces recirculation load. Oval throw action makes MEKA screens virtually non-plugging and raises quality output. The ability to fine tune stroke angle, amplitude and speed adds versatility in meeting changing screening conditions. Extra-strong body construction, durable bearing mountings, computer designed chrome-moly-nickel gear set with premium metallurgy extend service life.
HIGH STRENGTH SCREEN BODY
The body of the screen is extremely strong supporting the stresses required by the high power mechanism. This rigidity is provided by frames made from beam sections with stiffeners positioned in critical areas. Side plates are made from high quality steel and laser cut holes. Frames are huck-bolted to the side plates insuring structural integrity and eliminate stress fatique in the screen body.
SCREEN DECKS
The Horizontal screens can accommodate all media types, wire cloth, urethane and rubber. Steel Wire cloth is suitable for the screening of low moisture materials that are non-corrosive and nonabrasive, and that will not cause clogging or accumulation problems.
RUBBER AND POLYURETHANE SCREEN MEDIA
Rubber and Polyurethane screen media is used for the screening of highly corrosive materials that require high abrasion resistance. They are more resistant to clogging and material accumulation than steel wire mesh.
WET SCREENINGWET SCREENING
The washing system has been designed for complete reliability with; Replaceable nozzles,Inclinable perforated tubes that can adjust the angle of the jets,An adjustable valve per spray pipe, Sealing boots along the side plates,Perforated rubber tubes.
MOUNTING ARRANGEMENT
The mounting arrangement of MEKA Horizontal Screens is with coiled springs or with reinforced rubber springs depending on the application.
BEARINGS AND LUBRICATION
Self-aligning taper roller bearings are used to withstand the high thrust and radial loads under which the drive shafts of the triple drive system operate. The roller bearing lubrication is carried out by oil lubrication in an oil bath, which reduces operating temperature for increased bearing life and results in low maintenance.

High Frequency Screens
The High frequency screens, commonly referred to as “PEP screens”, come in a variety of sizes, frequency levels nd configurations. Fine material is best separated with high speed and a small stroke. They are available in single or double deck configurations, and are equipped with either electric or hydraulic vibration. The ratchet-type screen tensioning makes for easy screen panel changes.
Features
- Increase production by removing fines in pre-screening or post-screening applications
- VFD to control vibration speed
- Fine material is best screened with a faster speed and small stroke/throw
- Aggressive 3600 RPM applied directly to the screen media for optimal separation
- Faster screen media changes with a tool-free ratchet system
- Highest capacity in the industry for fines removal
