Heavy duty ribbon blender is the core equipment for large-scale industrial mixing. It adopts thickened steel plate cylinder and heavy-duty transmission system. It forms a "∞" font material flow through external screw belt propulsion + internal screw belt shear. It completes a batch of 1-20 tons in 5-15 minutes. Wear-resistant tungsten carbide edge and manganese steel lining plate to deal with strong wear conditions such as ore powder. PLC intelligent control can achieve technical services for remote control and is one of the indispensable equipment for large production plants.
With its unique design and function, heavy-duty screw-belt mixers show significant advantages in the mixing of high viscosity and high solids materials.
Extra large capacity: can complete batch processing capacity of 1-20 tons, adapted to industrial continuous production.
Double helix screw belt design: The outer layer screw belt pushes the material from both sides of the kettle body to the center, and the inner layer screw belt is conveyed in reverse, forming a three-dimensional mixing mode of "up and down rolling + left and right convection".
Suitable for high solid content: It can process materials with solid content up to 80% (such as mortar, ceramic slurry) to ensure uniform dispersion of solid particles. .
Customized design: The screw belts have a variety of forms, and can be configured with single-thread belt, double-thread belt, and screw-screw composite structure to meet different mixing needs.
Due to its large capacity, high wear resistance and strong power, heavy-duty screw-belt mixers are mainly used in the following industrial fields for high-strength mixing needs.
Building materials industry: In the production of dry powder mortar, heavy-duty screw belt mixers can evenly mix raw materials such as cement, quartz sand, and the residual amount is ≤0.3%; when used in ceramic tile glue and waterproof coating, ensure that the glue powder and aggregate are fully integrated.
Chemical industry: In the field of pigment dyes, each batch of equipment can process 5-10 tons of titanium dioxide, iron oxide and other materials to effectively avoid color difference; for plastic masterbatch production, ensure that the color masterbatch and the carrier resin are highly uniformly mixed.
Metallurgy and Mining: used for pre-mixing ore sintered sintered materials, can withstand high temperatures of 300℃, and is suitable for iron ore, copper ore powder, etc.; when treating metal powders such as tungsten powder and cobalt powder, explosion-proof design ensures production safety.
Food and Feed: For bulk raw materials such as flour and feed additives, 10-20 tons can be processed in a single time; when producing functional premixes, ±1% accuracy control is achieved for trace additions such as vitamins and minerals.
The heavy-duty screw belt mixer achieves efficient three-dimensional mixing through the reverse rotation of the double screw belt: the external screw belt promotes the axial movement of the material at a linear speed of 0.5-1.2m/s, and the internal screw belt rotates in reverse to form strong shear, and the material forms a "∞" font-shaped circulation track in the cylinder body with the flow stop plate.

We provide heavy-duty screw-belt mixers made of carbon steel and stainless steel for customers to choose from.
Carbon steel material: It has the advantages of low cost and high strength, and is suitable for handling non-corrosive dry materials, such as mineral powder mixing in the building materials industry, sintered material pretreatment in the metallurgy industry and other scenarios. However, it has poor corrosion resistance and is prone to rust in humid or acid-base environments. It is mostly used in industrial fields with low requirements for corrosion resistance.
Stainless steel material: represented by 304 and 316L, it has excellent acid and alkali corrosion resistance and oxidation resistance, and has a smooth surface and is not easy to contaminate materials. Among them, 316L is more corrosion-resistant and is often used in industries such as chemical industry, food, and medicine that have strict hygiene requirements, such as food additive mixing and pharmaceutical intermediate stirring.
There are significant differences in the functional use, working principle, applicable materials, equipment structure, operation and maintenance of heavy-duty screw-belt mixers and ordinary vibrating screens, which make them suitable for different links of industrial production.
