Elevator

Basic introduction

Elevator is a kind of mechanical conveying equipment with fixed device, which is mainly suitable for continuous vertical lifting of powdery, granular and small piece materials. It can be widely used in various sizes of mineral processing plants, feed mills, flour mills, rice mills, oil mills, starch mills, as well as grain warehouses, port terminals and other places of bulk material lifting operations.

The equipment is used for vertical lifting of lumpy and granular materials such as ore, limestone, coal, gypsum, clinker, dry clay, etc., which have passed through the crusher, as well as powdered materials such as raw material, cement and coal powder.

Classification and Characteristics

Classification of discharging method

• Centrifugal unloading: the bucket speed is faster, suitable for conveying powder, granular, small pieces of small abrasive materials.

• Gravity unloading: bucket speed is slower, suitable for conveying lumpy, specific gravity, abrasive materials, such as limestone, clinker and so on.

• Mixed unloading: combining the characteristics of centrifugal and gravity unloading.

Classification of traction components

• Ring chain: simple structure and manufacture, firmly connected with the hopper, good wear resistance, but the self-weight is bigger.

• Plate chain: solid structure, light weight, suitable for large lifting capacity, but the articulated joints are easy to wear.

• Adhesive tape: simple structure, but not suitable for conveying abrasive materials.

  • Ordinary tape: material temperature does not exceed 60℃.

  • Corded tape: material temperature up to 80℃.

  • Heat-resistant adhesive tape: material temperature up to 120℃.

  • Ring chain, plate chain: material temperature up to 250℃.

Scope of application of elevator

This series of bucket elevator is suitable for conveying powdery, granular and small piece of non-abrasive and less abrasive materials, such as: coal, cement, stone, sand, clay, ore and so on. As the traction mechanism adopts ring chain, it is allowed to convey materials with higher temperature (the material temperature does not exceed 250℃). The general conveying height is up to 40 meters.

Elevator product features

• High efficiency and energy saving: small driving power, inflow feeding, induced discharge, large-capacity hopper intensive arrangement, almost no return and digging phenomenon in the lifting process, less ineffective power.

• Widely applicable: low requirements on material types and characteristics, not only can lift general powdery, small granular materials, but also can deal with more abrasive materials; good sealing, reduce environmental pollution.

• Reliable operation: advanced design principles and processing methods to ensure the reliability of the whole machine, trouble-free time of more than 20,000 hours; smooth operation, can achieve a large lifting height

• Long-lasting durability: inflow feeding avoids material extrusion and collision, and reduces mechanical wear; reasonable design reduces material spilling, and prolongs service life.

Elevator working principle

The material is scooped up from the lower storage place by hopper, lifted to the top with conveyor belt or chain, and then turned downward after rounding the top wheel to dump the material into the receiving trough.

• Belt drive: rubber belt is used, mounted on the drive roller and redirecting roller.

• Chain drive: equipped with two parallel drive chains with drive sprockets and reversing sprockets.

The equipment is usually equipped with a housing, which effectively prevents dust from flying and keeps the working environment clean.
