INTRODUCTION:
Whilst enjoying immense popularity for many years on small horizontal and inclined screens, Linear motion screener offers a highly efficient approach to screening. This single development has resulted in tremendous advantages as far as reduced maintenance, compactness and simplicity are concerned. Besides the simplicity of the drive, many other features have been incorporated to provide a machine which is specifically designed for heavy duty applications, long life, and low operating and maintenance costs, at a competitive price. The standard range of screens is presented later in the brochure, and these are normally available on short delivery.
OPERATION:
Linear Motion Screen is equipped with two vibrating motors rotating in opposite directions. This dual motor configuration causes the screen frame to vibrate in a linear or straight-line motion perpendicular to the plane of the motors. Normally, the motors are positioned at an angle of 50 degrees with respect to the screen surface. This result in excellent forward conveyance of oversize particles , even when the screen frame is in an uphill position. Depending upon the application, the screen frame can be position from 10 degrees uphill to 15 degrees downhill. Maximum capacity is achieved in the uphill position, causing the formation of a pool at the feed end of the machine. The head or pressure from the pool increase fluid throughout. The linear motion of the screen frame efficiently conveys the oversize particles out of the pool area where they are then discharged.
FLEXIBLITY:
The screens can be adapted by the factory to meet special requirements regarding plant layout, screen performance and environmental constraints. Specify your particular requirements, or enquire about the range of features, accessories, painting systems and materials of construction currently available. Screens are frequently manufactured in various grades of stainless steel for the chemical industry and protected by special painting systems for severe conditions in the mining industry.
VIBRATORY MOTORS:
These rugged, heavy duty units are exceptionally well insulated against the ingress of dust and water. Their IP 55 protection ensures that the units can operate in wet conditions, such as in washing and dewatering applications. A very generous holding-down bolt design is incorporated.
A common complaint in the past has often been that vibratory motors tended to come loose. A great deal of thought and attention has been given to the fastening design of these motors. When compared with other makes of vibratory motors, the holding-down bolts are often in excess of 50-100% over designed. This, together with stress-relieved and machined surfaces and correctly torched nuts and locknuts, results in an exceptionally secure vibrator fastening system.
When two vibratory motors of the same frequency are fixed to a rigid common base, which is freely suspended, or supported and run in opposite directions to each other, they automatically synchronize to produce a straight line motion. When this motion is applied to a screen, the result is a horizontal action screen suitable for screening, conveying and dewatering of a large variety of products in limited headroom situations.
Linear Motion Drives:
Two Unbalance Motors: These are arranged as a double drive which produce linear vibrations. They are mainly used for medium-sized vibratory screens. Due to linear vibrations, these screens have much lower downwards inclination than those with shaft drives. In special cases can even run without any inclination or with a slight incline.
Exciters: Drive units of this type also produce linear vibrations. They are mainly used for vibrating heavy duty large and very large screens. When more than one exciter is being used in very large screens, vibratory force is uniformly and efficiently transferred from the exciter to the screen. The drive motor of the exciter is a standard foot-mounted motor. The motor torque is transmitted to the exciter either directly via a cardan shaft or indirectly by a v-belt drive or a variable speed gear. The indirect drive allows the user to adjust the rotational speed.
