Non-gravity Double Shaft Paddle Mixer
The Non-gravity Double Shaft Paddle Mixer is Tongding Machinery Equipment Company a high-performance mixing machine designed for dry mortar, tile adhesive, wall putty, gypsum plaster and various powder materials. Through synchronized counter-rotating shafts and specially designed paddles, the mixer creates a fluidized "non-gravity" mixing zone, allowing materials to move in multiple directions simultaneously and achieve fast, uniform blending. This mixer is widely used in dry mortar plants, tile adhesive production lines,wall putty plants, chemical powder processing plants and additive manufacturing facilities.
Why Choose Our Double Shaft Paddle Mixer
Fast Mixing Time
3‑5 minutes per batch, depending on formula.
>98% Uniformity
Consistent product quality, batch after batch.
Low Energy Consumption
Optimized paddles reduce power usage.
Fast Discharge
Large door, minimal residue, quick unloading.
Stable Operation
Heavy‑duty gearbox & direct drive, 24/7 reliable.
Wide Material Range
Dry mortar, tile adhesive, gypsum, additivesmortar productioncementing materials, putty powder, soil curing, masterbatch etc. 
Working Principle
The mixer adopts two counter-rotating shafts equipped with specially arranged paddles. During operation, materials are thrown into a fluidized mixing zone where particles move in radial, circumferential and axial directions simultaneously. This unique non-gravity mixing principle ensures rapid and highly uniform blending without dead corners.
