20T/H Refractory Castable Dry Mix Plant Aggregate Batching Double Shaft Mixer PLC Control

20T/H Refractory Castable Dry Mix Plant

Refractory castable and gunning mix are graded products. Each particle size band has to enter the batch in the right ratio, otherwise the packed density and the flow value of the castable fall outside the specification. This plant is therefore built with four separate aggregate bins and a wear resistant mixer.

Main System Composition

• 4 aggregate bins for 0-1 mm, 1-3 mm, 3-5 mm and 5-8 mm grades with individual belt feeders
• Aggregate weighing hopper with load cells and pneumatic discharge
• Binder hopper for calcium aluminate cement, micro silica and additives with screw dosing
• 3 m3 double shaft paddle mixer with replaceable wear resistant liner segments
• Pulse jet bag filter on mixer top and packing point
• Finished product hopper with valve type bag packing machine
• PLC control cabinet with 30 recipes and batch traceability record

Technical Parameters

Design Points For Refractory Mix

Each aggregate grade is weighed separately instead of being blended in one hopper, so the batch record shows the exact figure for every size band. When a customer asks for the batch data of a delivery, the record can be printed from the PLC directly.

The mixer liner is built from replaceable segments, which means the maintenance team changes only the worn segment instead of the whole trough. This keeps the mixer in service for a long period on abrasive refractory aggregate.

Applications

Refractory castable, gunning mix, ramming mix, tundish covering agent, and other graded mineral powder blends.
