Twin Shaft Paddle Mixer In China
Twin Shaft Paddle Mixer In China
Non-gravity double shaft paddle mixer for dry mortar, tile adhesive, and powder blending — with 5-year warranty and CE certification.
Product Overview
The Twin Shaft Paddle Mixer in China (also known as the Non-Gravity Double Shaft Paddle Mixer) is a high-efficiency mixing solution designed for dry mortar, tile adhesive, wall putty, and powder blending applications. With mixing uniformity above 99% and fast 3-5 minute cycles, it is the preferred choice for medium and large dry mortar production plants.
Unlike traditional ribbon mixers, the twin shaft design creates a fluidized mixing zone where materials are suspended in the air and mixed rapidly. This eliminates dead corners and ensures even dispersion of micro-additives such as HPMC, RDP, cellulose ether, and fibers.

Key Advantages
Patent-Protected Design Features
- Patented shaft end seal (Patent ZL 2018 2 2074615.5): Water-based graphite packing with silicone core ensures zero powder leakage — a common failure point in other mixers.
- Large-opening discharge door with automatic angle adjustment: Four-cylinder linkage ensures reliable sealing and prevents material leakage (Patent ZL 2018 2 2075756.9).
- 40CrMoTi wear-resistant alloy steel blades: Extends service life 40 times longer than standard steel blades.
- Direct-connected hard-tooth surface reducer: Prevents dual-shaft collision that can cause equipment shutdown.
- Independent air accumulator: Ensures stable pneumatic operation.
- Optional automatic lubrication system: Regular oil injection for seals, extending service life.
- Double-layer hard seal + large-opening double seal: Patented design (ZL 2018 2 2074615.5) ensures reliable sealing even under continuous operation.
What Our Customers Care About
Quality Assurance
Each mixer undergoes rigorous quality control:
- Blade geometry and clearance inspection
- Shaft end seal pressure testing
- Discharge door sealing verification
- Full-load test run before shipment
We offer a 5-year warranty on major components including the main shaft, paddles, and drive system. If the mixer fails to achieve the specified uniformity (≥99%) within the agreed cycle time, we will refund your investment.
Application Flexibility
One mixer can produce multiple products by simply changing the production formula via PLC control:
- Tile Adhesive
- Wall Putty
- Masonry Mortar
- Skim Coat
- Plaster Mortar
- Self-Leveling Mortar
- Dry Mix Mortar
