loading technology

Silo discharge technology

 
Fluidisation plates enable an easy discharge of fine and powdery bulk material avoiding the formation of lumps. This fine and powdery bulk material is loosened and mixed by blowing in air thus facilitating a trouble-free discharge.

Large ventilation surfaces require only small air quantities if the fluidisation plates are subdivided in sectors. The robust design enables an optimal and even material distribution.

BEUMER Bulk material

Large quantities of bulk materials must be transported by road and by rail. These bulk materials, whether building materials, coal, grain, animal feed, mineral aggregate or products from the chemical industry, are frequently loaded at the production site and transported as mass bulk material to their sites of use by means of appropriate vehicles.
It is essential to provide technical loading and unloading equipment designed for the handling of specific products and exactly adjusted to the assembly conditions. During the design phase the characteristics of each type of material to be loaded need to be considered, in par ticular with regard to the bulk density, product tempe rature and flow behavior.
Other important criteria include the loading capacity, weight and volume control as well as dustfree, environmentally safe operation.

BEUMER Group is one of the leading manufacturers of loading equipment for bulk material. Decades of experience, unsurpassed quality, comprehensive know-how and continuous innovative development of this product line ensure a high degree of availability and economical operation for the customer.

Loading head
for tanker vehicles

Tanker vehicles can be loaded quickly and free of dust by means of the BEUMER Group bulk loading head. It is designed according to the double-wall system i.e. material flow and dust extraction are separate from one another. The loading head must be connected to a dust-collecting air system. The lifting device is a motorized or manual cable winch. The material feed must be dosed. The device is operated by means of a suspended push-button switch.

When setting down on a filling spout, the sealing cone of the loading head lowers further and simultaneously opens the material outlet spout. The variable lowering level of the sealing cone with filling level indicator makes it possible to adjust the material level in the vehicle. For setting down, the loading head can be moved to the side to conform precisely to the position of the vehicle. At the end of the loading process the vibrator starts to loosen any material left in the head to prevent dust accumulation on the vehicles.

Loading head
for tanker vehicles
with integrated filter

The advantage of the BEUMER bulk loading head with integrated compressed air filter is its independence from a central dust extraction and transport system, which is too costly to install just for connection to a bulk loading unit. The dust removed from the vehicle is fed back to the material infeed during the loading process. The compressed air filter consists of filter bags located between the interior telescopic material feed tube and the outer bellows. A fan on the exterior extracts the dust. The unit is cleaned by jets of compressed air controlled by a timing relay. The customer must supply the required compressed air with 4 - 6 bar. Otherwise, the loading operation is the same as for the standard loading head.

Loading equipment
for open vehicles

For dust-free loading of open vehicles, various types of telescoping loading systems are available. At the start of the loading process, the head is lowered to the base of the vehicle and material feed is switched on. The unit is raised automatically by a filling level monitor located at the lower end of the conical valve which is dampened by the upward material. The bottom of the conical valve always remains on top of the material so that no dust can escape to the outside. The dust extraction bellows or telescoping tubes are connected to a central dust suppresion air system. Material is fed in by corresponding equipment or rotating gates.

Filling level monitors
for loading heads

The filling level monitor serves to accurately shut off the material feed to the loading head when the vehicle is full. Different types of filling level monitors are required depending on the properties of the material being loaded. The primary criteria used to select the correct switch are the bulk density, flow behavior as well as the product temperature. All systems are interchangeable. This ensures quick and trouble-free conversion if required.

Mobile loading equipment
for tanker vehicles

With very large loading requirements, for example in the cement industry, stationary loading heads are no longer sufficient, particularly in those cases where the vehicle is positioned on a scale during loading and cannot be moved. The loading head must be moved to each filling spout on the vehicle. Depending on material properties and length of the vehicle, several mobile or articulated conveying units are available: These mobile conveying devices can be equipped with 1 or 2 loading heads according to the requirement.

BEUMER Group automatic
dispatch control systems

Today bulk material loading stations are checked and controlled automatically. Integration as well as dispatch logistics often require a tailor-made concept. BEUMER Group offers solutions for the specific requirements of each customer from single loading controls to full material flow control.

These are implemented using the following system components which have been tested and tried many times.

  • material flow control via SPS
  • computers for processing weighing information and customer data, implemented as Windows NT work station
  • connection between material flow control and computer weighing system via field bus system or alternative via data carrier with corresponding input and output terminals
