Twin-Shaft Forced Mixer
Applications
-
Paste and quasi-paste filling plants
-
Underground coal and metal mine backfill
-
High-concentration paste preparation
-
Mixing of tailings, gangue, aggregates, and binders
-
Conditioning of high-viscosity industrial solid waste
Key Features
-
Intensive Twin-Shaft Mixing
The bidirectional twin-shaft configuration creates intensive three-dimensional material movement inside the mixing chamber.
This promotes thorough mixing of solid materials, water, and binders while reducing dry-material agglomeration and material segregation.
-
Multi-Layer Shaft-End Sealing
A four-layer composite shaft-end sealing system is designed to help prevent material leakage under high-concentration and high-pressure mixing conditions.
-
High-Wear-Resistance Components
Mixing blades and tank liners can be manufactured using high-chromium wear-resistant materials to withstand continuous contact with abrasive gangue, tailings, and aggregate.
This helps extend component service life in demanding mining applications.
-
Continuous Operation
The mixer is designed for continuous production and stable discharge, making it suitable for backfill plants where a consistent material supply is required by downstream pumping equipment.
-
Role in the Backfill System
The Twin-Shaft Forced Mixer is the core mixing equipment in the material batching and mixing stage.
A typical process includes:
Gangue / Tailings → Batching → Binder Addition → Water Addition → Twin-Shaft Mixing → Backfill Pump → Underground Filling Area
The mixing parameters can be configured according to the characteristics and formulation of the required backfill material.
-
Designed for High-Concentration Materials
Unlike conventional mixing applications, mine paste backfill can contain a high proportion of solids and may have significant viscosity and abrasiveness.
The GOLDDRILL mixer is designed around these operating conditions, with attention to mixing intensity, wear resistance, shaft sealing, discharge stability, and integration with downstream pumping equipment.
Custom Configuration
GOLDDRILL can customize the mixer according to:
● Backfill material composition
● Solid concentration
