Silo (elevator) equipment

Cleaning
Before bulk materials are stored in intermediate silos, they are usually cleaned. Cleaning may have a positive impact on the storage capabilities. At the same time, the quality of further processing is significantly improved.
To separate ferrous particles, magnetic separators are used. Coarse foreign objects such as strings, pieces of wood, and similar matter are removed by drum sieves. High-capacity cleaners eliminate low-density impurities and dust as well as coarse impurities and fine, high-density impurities (sand) and shriveled grains.

Magnetic separator

Rotary magnet

Drum sieve

High-capacity cleaner

Classifier separator

Weighing
For checking the weight of bulk materials, fully electronic weighing systems are applied. They transmit the measured data directly to master process control systems and/or print them out locally.

Granex batching scale

Tubex batching scale

Transflotron continuous scale

Storage
After reception (intake), cleaning, and weighing, the bulk material is transferred by chain conveyors to the storage silos. The material is fed to the individual silos through outlet gates or slides.

Storage silo equipment
Material storage and discharge is controlled by material level probes installed at different levels. The temperature of the materials is continuously monitored by temperature probes to ensure that certain material temperatures are not exceeded. Overpressure and underpressure valves ensure that the positive and negative silo design pressures are not exceeded. In order to prevent spoilage of the materials during storage, measures such as discharge, turning-over (into a different silo), or cooling (silo ventilation) may be taken. To limit pest infestation, different fumigation methods are applied.

Discharge
For storage silo discharge, outlet slide gates and possibly special dischargers such as sweep augers or chain conveyors are used, depending on the specific design.

Dust control
Efficient dust control of machinery and devices by bag (sleeve) filters ensures maximum cleanliness in plants, which is a preventive measure against dust explosions.

Small vertical filters

Low-pressure filter

Explosion protection
Buhler offers extensive consulting on the optimal protection against dust explosions according to the ATEX directives. Based on the safety analyses of the machines, Buhler will supply the required manufacturer conformity declarations.
