MEKA Horizontal Screens Designed For The Toughest Applications MEKA Horizontal Screens are a combination of quality, reliability, and performance; providing a long service life while operating under the most demanding applications. Nowadays, customers are requiring tighter specifications for products for precisely shaped aggregate or closely-sized stone. As a result, tighter control over the process is of utmost importance and the most effective point to do that is at screening. For that critical step you can trust MEKA Horizontal Screens. The screens elliptical motion is combined with high acceleration,...

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. These screens provide outstanding performance for all screening and can be widely applied in mining, aggregates, and concrete and asphalt recycling. The special applications...

HORIZONTAL SCREENS Oval Stroke Geared To Productivity MEKA Horizontal Screens generate power via three-shaft impulse mechanism located in the centre of the screen body with eccentric counterweights. The combination of the three shafts provide an oval stroke with adjustable amplitude, speed and operating angle, determined by application. Oval stroke screen action combines the best features of the circle and straight line throw into a unique oval stroke, by benefiting from the screening of the circle throw with the conveying action of the straight line. The motion is nearly vertical through the...

HORIZONTAL SCREENS Adjusting the stroke angle has been found to be the most influential in optimising the screen efficiency. Higher stroke angles increase the number of chances the material has to pass through the openings and also increases the impact to shake fines loose. Lowering the stroke angle increases the travel rate for heavy screening or scalping operations. Higher speed is sometimes desired for scalping duty. C B Other benefits include, • Less horsepower required • Smooth running-eliminates jerking action of straight stroke screens • Adjustable angle and length of stroke • High capacity...

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. MEKA CRUSHING SCREENING AND CONCRETE BATCHING TECHNOLOGIES www.mekaglobal.com

MOTOR BASE The motor base coupled with the belt tensioning system enables a practical motor assembly and V belt - pulley replacement, and provides energy efficiency by keeping the belt tension at the desired level. In addition, by providing a bolted connection between the motor frame and the main frame, cracks and fatigue issues associated with welding are avoided.

MEKAHORIZONTAL SCREENS MEKA CRUSHING SCREENING AND CONCRETE BATCHING TECHNOLOGIES www.mekaglobal.com SCREEN DECKS MEKA 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 non-abrasive, 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...

WET 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, WIRE CLOTH STRETCHING SYSTEM Screen meshes are fastened to the screen body by means of screen clamps and sheet bars, after being well stretched at the edges by the tension sheet. Thus, any slackening of the screen meshes during the screening process is prevented. MEKA CRUSHING SCREENING AND CONCRETE BATCHING TECHNOLOGIES...

MOUNTING ARRANGEMENT The mounting arrangement of MEKA Horizontal Screens is with coiled springs or with reinforced rubber springs depending on the application. Coiled spring is used when there is no threat of corrosion or abrasion, when there are plenty of opportunities for maintenance and spring replacement, and when loss of time due to problems caused by spring fracture is not an issue. Rubber spring should be used when there is a risk of corrosion or abrasion, when there are limited opportunities for maintenance and spring replacement, and where any halt in production will result in significant...
