Screen Drive Drive is totally enclosed, weatherproof electric motor, rated in accordance with data charts, and vee rope transmission. Optional starter is equipped with electric plug braking.
The eccentrically-bored screen sheave offsets the stroke so that drive centers do not change during operation. Other than a V-belt transmission, a drive motor with a cardan/propeller shaft (universal coupling) can also be used to drive the vibrator assembly.
Patented Weight Drive Technology Ensures Effective Screening The key to our enhanced industrial screening performance is our patented weight drive technology. BM&M’s drives use a stationary shaft and a high-speed eccentric weight that rotates on a bearing assembly to generate an eccentric
Centralized drive lubrication system, providing safe access for lubrication during operation; Easily replaceable heavy gauge steel screens. Choose perforated or wire mesh screens with variable wire diameter as required for accurate material classification. Optional ball deck assemblies prevent wet material from blinding screen openings.
Each unit is built on platforms that combine a machine width and a drive type, consisting of an eccentric shaft assembly with bearing sizes ranging from 120 to 160 mm Within the platform, the customer chooses basic parameters, such as screen length and the quantity of decks the application requires.

Generally, power is transmitted from the drive motor to the vibrator assembly via a V-belt transmission. The speed of the vibrating screen (vibration frequency) can be adjusted by changing the ratio of the V-belt sheaves. The eccentrically-bored screen sheave offsets the stroke so that drive centers do not change during operation.

Vibratory Screen Eccentric Bearing Assembly. Mar 28 2016nbsp018332Two of this bearing assembly would be used in a screen box and the shafts of the two assemblies are connected by a middle shaft with universal joints Extra weight can be added to the rotating eccentric weight to increase or reduce vibration The main bearing housing is bolted to the side plate of the screen box
Gyratory equipment, used in mechanical screening and sieving is based on a circular motion of the machine. Unlike other methods, gyratory screen operates in a gentler manner and is more suited to handle fragile things, enabling it to produce finer products. This method is
A pre-aspiration and final aspiration column are standard that deliver a precise separation for light density waste material. All outlets are self-cleaning. Standard equipment includes a mechanically variable eccentric drive. This unit is also available with a screen width of 1067 mm (42”).
the feed coming onto the screen in order to thin out the bed and provide even quicker stratification, the adjustable panel permits the required increase of slope. If it has been found that at the discharge end of the screen, where the bed has thinned out, that the particles have a ten-dency to pass over the screen a
Prater Rotary Airlocks are used worldwide throughout a large variety of industrial and agricultural bulk and specialty material handling systems. We specialize in the design and manufacture of custom-built rotary airlock valves that can immediately improve the safety, reliability, and efficiency of your feeding and metering operations while

Prater Lump Breakers are functional, economical and designed to tear through most materials and reduce them down in size as small as 1/16” without generating excessive dust. Our Lump Breaker design is proven to provide a simple and efficient process of reducing compacted materials into a smaller and controlled granulated product allowing for
Power is transmitted from the source to the countershaft to a V-belt or direct drive. The countershaft has a bevel pinion pressed and keyed to it and drives the gear on the eccentric assembly. The eccentric assembly has a tapered, offset bore and provides the means whereby the head and main shaft follow an eccentric path during each cycle of
Traits of an Eccentric Person. According to psychologist Dr. David Weeks, there are around 15 characteristics that can distinguish a normal person from an eccentric individual. He also says that individuals having a mental illness ‘suffer’ from their behavior, however, eccentrics are rather happy.
