Double-screw mixer

Twin-screw mixer technology level and technical features

Operating Principle:

The twin-screw mixer rapidly blends materials, with the spiral blades of the agitator shaft in motion, causing the inner and outer spiral blades to flip the material over a wide range. The inner spiral blade moves the material to the sides, while the outer spiral blade draws the material inward from the sides, creating a back-and-forth渗混 process. Additionally, some material is propelled by the spiral blades without axial or radial movement, thus forming a convectional circulation. Due to the aforementioned motion of stirring, the material achieves a quick and even blend in a shorter period of time.

Structural Features:

Horizontal screw blade mixer is a horizontal simple body with inner and outer spiral blades in a * configuration. It operates smoothly, is reliable in quality, low in noise, has a long service life, is easy to install and maintain, and features a wide range of blender structures for versatile mixing equipment. It has fast mixing speed, high degree of uniformity, especially for sticky materials. Scrapers can be installed on the spiral blades for better mixing of paste-like substances. Under different mixing requirements for various materials (special materials must be cleaned after each mix), different spiral structures are used, including jacketed types for heating and drying, special atomized liquids, and special nozzles. The horizontal body can also be equipped with a sliding door for user cleaning.

Application Scope:

The WLD horizontal mixer incorporates foreign technical data, processed and innovatively designed by our professional technical staff, making it a new type of mixing equipment. It is widely used for solid-solid (i.e., powder-to-powder) and solid-paste (i.e., powder-to-paste) material mixing in industries such as chemicals, food, compound fertilizers, dyes, pigments, rubber, building materials, milk powder, feed, additives, aquaculture, biotechnology, fine chemicals, ceramics, wear-resistant materials, rare earths, plastics, new materials, and nuclear energy materials.

Advantages Briefly:

Under the feasibility factors, the horizontal helical blade mixer exhibits excellent mixing results that are unaffected by particle size or density, and also provides good mixing for sticky materials. The smooth mixing process reduces damage to fragile materials, and the addition of a knife structure also serves to break them up. The horizontal structure has a lower body height, making it easy to install. In the mixing structure, both clockwise and counterclockwise rotating helical blades are mounted on the same horizontal shaft, creating a low-power mixing environment. The horizontal helical blade mixer is mainly used for the production of putty powder and can also serve as an entry-level thermal insulation mortar mixer. Double helical blade mixer*
