Grinding Plants Made of Mild Steel - Sample Installations

This fully automated grinding plant is used for pulverizing of polyethylene granules. A vacuum conveyor is feeding the grinding stock to the fluted-disk mill REKORD B-SM. The screening machine in the circulation system separates the coarse material to the mill for a re-grinding. The ground stock is collected in containers.

• Input material: polyethylene granules

• Capacity: up to 50 kg/h

• Final grain size: 99 % < 500 µm (35 Mesh)

• Explosion protection: pressure shock resistant up to 2 bar, relieved

• Cooling system for pneumatic conveying air

• Pneumatic conveying of the grinding stock

• Automatic and temperature-regulated dosing system

• Feeding from and into containers supplied by customer

This milling and dosing system is suited for the production of different base compounds. A feed tank with weighing system is dosing one component in accordance to the recipe to the mill. Other components are filled manually into a dosing hopper. The operator finds each set point of the recipe on the touch panel. The weighing system is documenting and monitoring the actual values.

A pneumatic conveying system transports the mixture components to a blender.

• Feed tank with agitator, discharge screw conveyor and weighing system

• Pin mill REKORD 224-SSt

• Explosion protection: pressure shock resistant up to 10 bar, relieved

• Pneumatic conveying system

• System control with recipe management

• Semi-automatic dosing system with nominal-actual value comparison

A well-defined particle size is needed for the production in the sintering process. This grinding plant for pulverizing tungsten carbide with a REKORD B was developed especially for a manufacturer of carbide tools.

• Input material: tungsten carbide

• Capacity: up to 300 kg/h

• Automatic and temperature-regulated dosing system

• Feeding from and into containers supplied by customer

This universal grinding and screening plant is specifically designed for grinding different materials in construction material industry. The impact crusher REKORD B can be equipped with 5 different grinding elements. The mill speed can be adjusted by a frequency inverter.

The process flow is flexible by using a screening machine:

• Pass through grinding: Direct product discharge and bag filling after grinding.

• Classification: Separation of the material in up to 6 different grain size fractions. These will be filled directly into bags.

• Circuit grinding: The coarse grain size range is supplied to the mill after grinding again.

• Input material: different building materials

• Grinding elements: pin-disk rotor, beater-disk rotor, fluted disk rotor, turborotor, cross-beater rotor

• Grinding elements detection for automatic speed limitation

• Screening machine for grain size determination

• Refeeding of the coarse grain size to the mill

• Touch panel for controlling and monitoring with process data archiving for a following analysis
