The Berndorf Band Group offers a wide variety of steel belt systems precisely made upon customer requirements and specifications. One business field of the Berndorf Band Group is the supply of feeding devices, solidification and cooling systems, summed up under the name Process Equipment. Process Equipment is mainly used in the chemical industry, but also other branches like the sulphur, food or powder paint industry can profit from this production line.
As total solution provider with experienced experts, we offer complete packages, starting from feasibility studies to engineering, design, manufacturing, construction and installation of your plant. With more than 30 years’ experience in this business field, we are your reliable partner and support you in all project phases. Our packages include steel belts, tailor made belt systems, turnkey installations, technical consultancy and a worldwide service.
In global available R&D centers customers can test Berndorf coolers and feeding devices on site to convince themselves of the advantages of Process Equipment.
Areas of Application
Single and double steel belt coolers engineered by Berndorf Band Group are used for a wide range of production processes. From cooling and crystallization to pastillation of materials like sulphur, powder paint, chemicals and food products in the shape of flakes, pastilles, strips or sheets, all customer specifications can be fulfilled with Berndorf single or double belt cooling systems.
The process of a steel belt cooler
To solidify the molten product, nozzles spray water on the bottom steel belt to guarantee uniform cooling of the product. To save the environment and to avoid a cross-contamination of the end products the systems are engineered to prevent contact between the product and the coolant. Additionally cooling water is collected in tanks.
Single Belt Cooler
The single belt coolers are mainly used for products with low specific heat, low viscosity and low density. Especially for manufacturing molded materials like pastilles, flakes, strips, etc. profit from this production line.
- Production of different shapes: pastilles, strips, strip granulate, flakes, plates, sheets, etc.
- Product specific temperature profiles due to different cooling zones
- Economical due to low operating and maintenance costs
- Environmentally friendly
Double Belt Cooler
Berndorf double belt coolers are mainly used for handling low and medium viscosities. Different feeding devices are available to be installed at the infeed of the machine to bring the product onto the belts. The pressure of the upper belt guarantees a fast cooling of the raw material which is cooled between both belt surfaces. Compared to single belt coolers, double belt coolers achieve better results with higher capacity.
- High production capacity possible
- Avoids curling away from waxes and resins
- Cooling of thicker products possible
- Reduction of fumes and dust
Berndorf feeding systems have been developed to meet different process requirements for a wide range of products. The versatile application possibilities enable the production of materials with different viscosities as well as the manufacture of pastilles in different sizes simply by exchanging the rotary outer shell and nozzle bar with or without refeed bar. Available Berndorf feeding devices are berndrop®, bernform® and bernflow®.
For pastillating processes berndrop® and bernform® are available. During this process low and high viscous products and a melt temperature of up to 300 °C can be produced.
- High production output
- Uniform product quality
- Good material flow characteristics and customized, dust free end products
- Side tightness to avoid product contamination into rotating partson & maintenance because of long shell cleaning intervals
