    Plate chain bucket elevator is a ring chain type which adopts the model of centrifugal unloading and dig-loading. Its traction mechanism is two circular chains. In Henan Pingyuan, this series is suitable for vertical conveying of the materials with the bulk density less than 1.5 t/m3. The powdery and granular materials are easy to dig, and the small lump materials have low abrasiveness such as coal, cement, gravel, sand chemical fertilizer, grain and etc. Besides, it can convey the materials with the temperature below 250oC. Bucket elevator is widely used in many industries for lifting powder,

    The bucket elevator is a kind of mechanical equipment used for conveying materials from a lower position to a higher position. This is one of the common mining machinery used in processing industries. It is able to convey large materials size and particles such as coal, cement, sand and rocks. If the Bucket Elevator malfunctions, the source of faulty operation may frequently be found by observing the nature of the fault and applying some simple checks and remedies to correct the malfunction. The following troubleshooting table is provided for this purpose.

    The design of spherical roller bearings is inherently self-aligning, i.e. angular misalignment between the outer ring and inner ring can be accommodated without any effect on bearing performance in Figure 1. Under normal loads and operating conditions (load ratio of C/P > 10) and when misalignment is constant in position with respect to the outer ring, the guideline values for permissible alignment applied. Whether these values can be fully exploited or not depends on the design of the bearing arrangement, type of seals used and etc.

    Drive is achieved by electric motor with carden shaft to the drive shaft equipped with twin unbalance adjustable weights where required additional v-belt drive can be provided. The number of exciters is increased according to screen width and two models are available with the exciters arranged above the screen or below depending on application.

    Vibratory applications such as vibrating screens or exciters, induce accelerations of rollers and cages in the bearings. This puts extra demands on the bearing design. PK Machinery spherical roller bearings for vibratory applications can withstand considerably higher accelerations than corresponding standard bearings. The permissible acceleration depends on the lubricant and the type of acceleration whether rotating or linear acceleration.

    Springs are used to convert the vibration from the drive to tray thus causing product to move. Springs come in a variety of materials, sizes and configurations. From thin sheets of fiberglass to dense rubber compounds to thick steel coils. Each material is designed for specific applications. In some applications, a combination of spring materials may be used.
