In industrial production, there is a need to move bulk materials vertically up to a certain height. For these purposes, a bucket belt bucket elevator was developed and created. This conveyor has become an indispensable unit in the technological process of production at many enterprises.

Elevator device

This industrial machine can be used to lift bulk materials and liquids. To transport the latter, a water wheel is used, similar to a water mill. Planes are built into its design, which fall into the water and rise up under the force of the current. To take the liquid, buckets of the required sizes are installed instead of plates.

The elevator bucket elevator is used in industry to lift loose materials. The components of the elevator are:

• shoe - the loading part of the mechanism, which is used for loading/unloading cargo;
• tape elevator head;
• drive mechanisms - directly the engine, auxiliary gearbox and transmission;
• Elevator mounting pipes;
• section for control (inspection) - necessary forbucket monitoring and can be used as a main repair site;
• elevator belt - the main element for moving goods;
• loading bucket;
• various control devices.

Working principle

The cargo required for transportation is placed in the bucket, which is in the lowest position. Due to the drive mechanisms, the belt with the buckets placed on it begins to move. The load moves vertically upwards, passing through the sections. The number and length of sections depends on the bucket elevator manufacturer.

Having reached the maximum upper mark, the belt continues its downward movement, and the bucket fixed on it turns over, unloading the material through the socket or nozzle. An empty loading container is already moving down, ready for the next shipment.

According to technological characteristics, the height to which materials are transported should not exceed 60 m.

Scope of application

Bucket elevator is used in those areas of industry where it is necessary to move loose materials. These are mainly mills and flour mills, storage facilities for grain crops, feed and chemical industries.

Practicing production workers note a number of advantages in working with this unit. It became possible to transport grain crops over considerable distances upwards with minimal effort and cost. At the same time, loose cargo is not crushed and does not receiveunwanted damage. The units are highly durable and have a long service life. The bucket elevator has compact dimensions, it is easy to install, versatile in operation. It does not require high energy consumption to function normally.

The unit can be used in enterprises where there is a need to transport cake. Its performance involves the delivery of loose cargo up to 500 tons in one hour. Due to the presence of closed modifications of buckets, the operation of the unit can take place under any climatic conditions.

Grain elevator

Grain bucket elevator is used as equipment for transporting and lifting grain and other small dry goods in the vertical direction. It is mainly used in flour mills and feed mills. Loading occurs by selecting the load with a bucket from the shoe, delivery to the top and unloading into the bunkers.

The material for the manufacture of grain elevators is both metal and polymer plastic. The latter material is more common. It is lightweight, does not damage the grain, thanks to its elastic edges. Wet bulk cargoes stick less to it.

There are grain elevators with UN marking and a coefficient of 5, 10, 20, 50, 100, 175, 250 and 500. The figure indicates the capacity of the unit, expressed in tons per hour. They also differ in bucket pitch, their capacity, drum diameter and belt width. For example, the maximum elevator UN-500 has a capacity of up to 500 tons perhour, its bucket pitch is 180 mm, with a capacity of up to 8.1 dm, the drum diameter is 800 mm, this model has two rows of buckets.

Noria NLC modification

These models have differences in belt width and performance. Thus, the bucket elevator NLK-100 is characterized by a belt width of 300 mm and a functional capacity of up to 100 tons per hour.

The units of this series transport grains and their processed products, oilseeds and other loose materials in a vertical position. Representatives of these modifications are used outdoors and indoors. They have a self-supporting design feature. They differ from their counterparts in their complete set, which includes an explosion arrester, brake units with automatic operation (prevent the belt from scrolling back during an unscheduled stop in the work process), a speed control relay, retaining sensors, hatches for belt tension and some other components.

This modification also includes a belt bucket elevator with a capacity of 350t/h and models such as NLK-5, NLK-20, NLK-50, NLK-100 and NLK-175.

HB Series

There are three representatives of the bucket elevator in this series - HB-50, HB-100 and HB-175. The units transport crops such as oilseeds, cereals, legumes, cereals, various other industrial crops and grain heaps. The bucket elevator is constructed from very high quality galvanized steel. Has a highsafety class: fire-resistant and explosion-proof.

The complete set includes speed and support sensors, mechanisms for speed control and protective functions, a braking device and an air purification system. There are additional mounting options in the form of installation of stairs with railings and service platforms.

HB series bucket elevators differ in performance, height, weight, width, dimensions and volumes of buckets, their number per certain footage, as well as the speed of the elevator belt, energy consumption and the amount of air for filtration.

Belt elevators

There are belt elevators and self-supporting belt elevators. The former transport granular materials in a vertical direction and also have buckets. The operation of the unit is provided by drums with drive and tension mechanisms. Buckets can self-pick product or are forcibly loaded with crumbly ingredients.

Belt elevators are marked H-3/10/20/50 and differ in technical characteristics such as productivity at percentage moisture, the number of revolutions of the drive drum and its diameter, the size of the head and buckets, the width and speed of the belt.
