Company Presentation:
GEROLDINGER – BULK SOLIDS LOGISTICS PLANTS FEATURING OUTSTANDING OPERATIONAL RELIABILITY
Geroldinger engineers and manufactures tailored solutions to move bulk solids reliably and precisely to various processes.
The materials handling specialist is a leading global provider of technology for a wide range of complex applications. Doing logistics between processes – buffer and convey bulk solids – Geroldingers solutions include silos, pneumatic, screw and chain mechanical conveyors. A variety of discharging and metering equipment like loss in weight feeders are offered.
Patented components like the OSZILLOMAT discharge and dosing aid especially developed for demanding bulk solids or the MULTIGON – an octagonal silo - allowing exceptional applications.
A UNIQUE PRODUCT FOR PRODUCERS AND PROCESSORS OF BULK MATERIALS
On the basis of Geroldingers experience with hundreds of plants and facilities the company developed a unique product for producers and processors of bulk materials - the Bulk Solids Logistics Plant. A one stop plant that buffers and conveys bulk solids in exact quantities at the right speed to wherever they need to go. Geroldingers Bulk Solids Logistics Plant proof outstanding operational reliability and a customized operator interface.
FLOW CHARACTERISTICS POSE SPECIAL REQUIREMENTS FOR HANDLING TECHNOLOGY
The flow characteristics of your material pose very special requirements for handling technology. In many cases, a given material proves difficult to handle only within the context of specific processes and degrees of automation. Environmental factors such as temperature and humidity or dwell time can also exert a significant influence on flow behavior.
MAIN BENEFITS OF BULK SOLIDS LOGISTICS PLANT
Bulk Solids Logistics plants ensure convincingly safe, reliable operation and guaranteed overall function= the movement of bulk material in precise quantities at exact speeds to predefined interfaces. This gives you outstanding investment security.
USE GEROLDINGER´S ESTABLISHED COMPETENCE WITH
DEMANDING BULK SOLIDS LIKE:
Aerosol, anhydrite-sand or grit, ash, bed ash, fly ash, bran, brick dust, carbon black, clay, chalk, cement, dry mortar, fertilizer, filter cake, fintalc, flour, foil chips, every kind of flakes ( dried pet food, wood, foil, wax, soap, paper, recycling material, textiles, electric waste), gypsum, kaolin, lime, meat and bone meal, melamin, milk powder, malt, oxalic acid, phosphate, plaster, provender, sludge, sugar, salt, starch from corn, grain or potatoes, blast furnace sludge, soja pellets, silica sand, soda, synthetic rubber, TIO2 ( titanium dioxide), urea, wood chips, … to name just a few.
TYPICAL PROBLEM FIELDS WE KNOW HOW TO PREVENT OR SOLVE:
Funnel flow, piping, segregation, encrustation of walls, fluidisation, bridge-building, shooting flow and unsteady fill factor, non-uniform unload of screw-conveyors...
THESE INDUSTRIES TRUST IN OUR SOLUTIONS:
Chemical industry, paper production / paper mills ( kaolin, titanium dioxide, starches), food industry, recycling industry, waste industry, cement industry ( meat and bone meal, lime, fly ash..), power plants (regarding solutions for bed ash and flue gas desulfurization with urea) , pharmaceutical industry, plastics processing industry, garbage incinerating plants ( sludge), wood industry ( urea, melamin), provender industry, primary industry,
SERVICES AND MAIN PRODUCTS IN DETAIL:
TURNKEY SOLUTIONS
Complete section of industrial plants constructed for the purpose of storing, discharging, weighing, dosing, loosening, blending, and conveying of bulk goods (especially those of low flowability). Includes all control systems and necessary equipment for mechanical processing.
STORAGE OF BULK SOLIDS
Round silos:
Made of aluminum, mild steel, stainless steel or carbon steel; up to 300
m3 ex works and 1,000 m3 at the construction site.
MULTIGON silo:
Achieves maximum silo volume in ratio with the available space due to it´s octagonal cross-section. MULTIGON is very economic - especially if a large number of cells and medium-sized volume are needed. The silo discharges autonomic and without residue because the completely smooth silo walls and the octagonal cell profiles which features 135 degree corners and cause a round silo effect.
DISCHARGE, DOSING, BLENDING AND WEIGHING OF BULK SOLIDS
OSZILLOMAT:
Live bottom discharge system for reliable discharging, dosing and blending of cohesive, adhesive, hygroscopic and elastic bulk goods up to degrees of 800 ° C. In combination with taylored silodesign the OSZILLOMAT ensures mass flow and reliable discharge, of even very bad flowing bulk materials and even solves the problem of segregation!
OTHER DISCHARGE AIDS:
- Agitators, multiple screw systems, vibration floors, pneumatic loosening
systems.
CONVEYING OF BULK SOLIDS
PNEUMATIC conveying
Based on pressure, suction or gas. Among others we provide low medium and high pressure conveying. Air or nitrogen are used as supporting media.
MECHANICAL conveying
Through srews (especially designed for difficult bulk or for cooling or dosing) elevators and througed chain conveyors
CONTROL TECHNOLOGY
Process control system, plc control and prescription control, system control units; From single systems to complex turnkey plants we provide you sophisticated control systems including process visualization which are easy to operate
ENGINEERING, CONSULTING AND TESTING SERVICES
Below you´ll find a description of 6 MAIN GROUPS OF BULK SOLIDS AND THE TECHNICAL PROBLEMS THEY CAUSE IN PRACTICE. Difficult bulk solids are often a mixture of two groups.
WHAT´S YOUR MATERIAL LIKE?
1) COHESIVE BULK SOLIDS
Main attributes:
- Pressure creates a inner tensile strength of the material
Particular technical problem:
- interrupted material flow due to bridgebuilding,
- reduced active silo capacity because building of funnels;
Main representatives of this group:
- kaolin, filter cake, moulding sand, titanium dioxide, starches, meat and bone meal, carbon black
References and Main applications:
- All industries especially paper mills and chemical industry
2) HYGROSCOPIC BULK SOLIDS:
Main attributes:
- Forms lumps, layers and crusts due to humidity migration
Particular technical problem:
- Blockaded inlets interrupt the material flow,
- funnel building due to incrustation of the silo walls
Main representatives of this group:
- Urea, phosphate, oxalic acid, salt, sugar, etc.
References and Main applications:
- Production of adhesives and fertilizers
- Flue gas desulfurization
- Purification plants
3) BULK SOLIDS WITH A TENDENCY TO SEGREGATION
Main attributes:
- Differences in specific weight of bulk goods and particle size and shape lead to a different rolling behavior and suspension speed
Particular technical problem:
- Vertical layers form during filling – segregation originates – how to prevent a fluctuation of particle distribution at outlet?
Main representatives of this group:
- Dried mortar, gypsum, silicium, etc. References and Main applications: production
4) FINEST GRAIN WITH MEDIAN < 20 µ
Main attributes:
- Easy to fluidize, mainly also cohesive
Particular technical problem:
- The material flows very badly in degasyfied mood, in gas-filled mood, dosing is very difficult due to a high flow rate; in cases the bulk solid is also cohesive a loosening by air is hardly efficient;
Main representatives of this group:
- Clay, chalk, fly ash, etc.
References and Main applications:
- Paper mills, clay production, power plants, cement industry
5) ELASTIC, COMPRESSIBLE BULK SOLIDS:
Main attributes:
- Material compresses and builds non flowing blocks
Particular technical problem:
- A stiffly conformed material block prevents material flow – requires large
scale trouble-shooting
Main representatives of this group:
- Foil chips, XPS-flakes ( polystrene), alternative fuels ( tires, waste..)
References and Main applications: recycling of synthetic material,
production of isolation pannels, cement industry
6) BREAKAGE-SENSITIVE BULK SOLIDS:
Main attributes:
- Big particle sizes, material breaks easily and is mainly also sticky Particular technical problem:
- Too much pressure leads to breakage of bulk – discharge system that solves adhesion without breaking the product.
Main representatives of this group:
- All extruded foodstuff and pet food
References and Main applications:
- Production of extruded foodstuffs, and pet food
BULK SOLIDS WITH TEMPERATURES UP TO 800 ° C
References and Main applications:
- Power plants, waste industry
