A Bucket Elevator can elevate a variety of bulk materials from light to heavy and from fine to large lumps.

A centrifugal discharge elevator may be vertical or inclined. Vertical elevators depend entirely on the action of centrifugal force to get the material into the discharge chute and must be run at speeds relatively high. Inclined elevators with buckets spaced apart or set close together may have the discharge chute set partly under the head pulley. Since they dont depend entirely on the centrifugal force to put the material into the chute, the speed may be relatively lower.

Nearly all centrifugal discharge elevators have spaced buckets with rounded bottoms. They pick up their load from a boot, a pit, or a pile of material at the foot pulley.

The buckets can be also triangular in cross section and set close to on the belt with little or no clearance between them. This is a continuous Bucket Elevator. Its main use is to carry difficult materials at slow speed.

Early Bucket Elevators used a flat chain with small, steel buckets attached every few inches. Current construction uses a rubber belt with plastic buckets. Pulleys several feet in diameter are used at the top and bottom. The top pulley is driven by an electric motor.

Bucket Elevators have proven themselves for vertical transport of many and diverse bulk materials for decades. As a market leader, DevconGroup successfully established the belt bucket elevator technology in the market decades ago.

Belt Bucket Elevators were consistently developed in the past and enable the highest possible conveying capacities with maximum centre distances today.

Chain Bucket Elevators are the preferred conveying systems for the transport of hot bulk materials and coarse-grained materials. With its central chain bucket elevators, DevconGroup offers efficient and proven solutions even for the highest conveying capacities.

A Stacker is a large machine used in bulk material handling. Its function is to pile bulk material such as limestone, ores and cereals on to a stockpile. A reclaimer can be used to recover the material.

Stackers are nominally rated for capacity in tonnes per hour (tph). They normally travel on a rail between stockpiles in the stockyard. A stacker can usually move in at least two directions: horizontally along the rail and vertically by luffing (raising and lowering) its boom. Luffing of the boom minimises dust by reducing the distance that material such as coal needs to fall to the top of the stockpile. The boom is luffed upwards as the height of the stockpile increases. Some Stackers can rotate the boom. This allows a single stacker to form two stockpiles, one on either side of the conveyor.

Stackers are used to stack in different patterns, such as cone stacking and chevron stacking. Stacking in a single cone tends to cause size segregation, with coarser material moving out towards the base. In raw cone ply stacking, additional cones are added next to the first cone. In chevron stacking, the stacker travels along the length of the stockpile adding layer upon layer of material.

Stackers and reclaimers were originally manually controlled, with no means of remote control. Modern machines are typically semi-automatic or fully automated, with parameters remotely set. The control system used is typically a programmable logic controller, with a human-machine interface for display, connected to a central control system.

Other than stacking, a stacker has three basic movements:

• Luffing: This is vertical movement. Stackers use either a winch mechanism with metal wire, or hydraulic cylinders, generally two. Winch mechanisms are highly reliable compared to hydraulic actuators and remain widely used, particularly in large stackers.
• Travelling: The stacker moves on a rail track, which may be broad or narrow gauge, enabling it to move around the stockyard as required. For this purpose, traction motors powered by direct current (DC) are connected by bevel gears to between 12 and 22 wheels. For manual control, all the controls are in a controllers cabin above the boom conveyor or boom. Modern Stackers can be controlled remotely.
• Slewing: This is rotation of the stacker around its central axis to align or place the stockpile where required. This works mostly by a slew pinion that rotates around a slew base. This type of gear assembly is called a sun and planet gear. The axles may be multiple and are driven by DC-powered axle motors which transmit the torque via bevel orhelical gears.

We have many standard pulleys available in both A or B style, one or two grooves, bushed or bored to size.We specialize in made-to-order pulleys for the agricultural industry. Devcon Systemsmanufactures pulleys for both light and heavy duty mowers.

A Reclaimer is a large machine used in bulk material handling applications. A reclaimers function is to recover bulk material such as ores and cereals from a stockpile. A stacker is used to stack the material.

Reclaimers are volumetric machines and are rated in m³/h (cubic meters per hour) for capacity, which is often converted to t/h (tonnes per hour) based on the average bulk density of the material being reclaimed. Reclaimers normally travel on a rail between stockpiles in the stockyard. A bucket wheel reclaimer can typically move in three directions: horizontally along the rail; vertically by luffing its boom and rotationally by slewing its boom. Reclaimers are generally electrically powered by means of a trailing cable.

All Types Of Reclaimers

The Reclaimer structure can be of a number of types, including portal and bridge, named according to this type, such as Bridge reclaimers. Portal and bridge reclaimers can both use either bucket wheels or scrapers to reclaim the product. Bridge type reclaimers blend the stacked product as it is reclaimed.

Bucket wheel reclaimers use bucket wheels for removing material from the pile they are reclaiming. Scraper reclaimers use a series of scrapers on a chain to reclaim the material.
