1, New energy industry (lithium battery)
This is one of the fastest growing applications in recent years. Biaxial reverse rotation mixing tank plays a central role in the lithium battery homogenization workshop.
Positive slurry (such as lithium ferric phosphate slurry and ternary material slurries) requires that active substances, conductive agent and binders are uniformly dispersed in solvents. The biaxial extrusion folding mechanism can control the very low solid content deviation and greatly improve the consistency of the battery.
Negative slurry requires high dispersion, and the low speed and high shear characteristics of biaxial can effectively avoid agglomeration.
The entire homogeneity of battery from raw material mixing to finished product discharge can be achieved by continuous biaxial equipment, from feed to discharge.
In addition, in the process of preparation of coal water slurry by dry process, shaft mixers is widely used to mix water and coal powder efficiently under dry conditions.
2, Chemical industry
biaxial reverse rotation is widely used in the chemical industry and covers almost all systems from low to high viscosity:
Adhesives and sealants: silicone adhesives, polyurethane adhesives, epoxy resin adhesives, and other High viscosity systems, can provide uniform biaxial shear field to achieve full dispersion.
Paints and inks: The dispersion of pigments and fillers in resins results in smaller particle size distribution and stronger coloring ability.
Silicone oil processing: Silicone oil itself is a high viscosity and difficult to mix quickly and evenly on a single axis. Two-axis reverse rotation can greatly shorten the stirring time.
Pesticides and fine chemical intermediates: mixing and reaction of paste and high-density materials.
Chemical reaction and post-treatment sections such as acid leaching tanks and lithium sedimentation tanks are equipped with acid and alkali resistant, high temperature biaxial equipment with a pH of 1-14 and stable operation at temperatures up to 95 °C. Some heat-resistant models can even withstand temperatures as high as 350 °C.
3. Building materials and concrete industry
This is the classic, largest application scenario for shaft mixers:
Premixed concrete (commercial mixing station): Double axle forced mixer is the mainstream equipment. Cement, gravel aggregates, fly ash, mineral powder, additives, water, etc., fuse rapidly under the action of shear, scattering and convection of biaxial blades, effectively avoiding segregation and bleeding, and ensuring the collapse and strength of concrete up to standard.
Dry powder mortar: cement, quartz sand, heavy calcium powder, cellulose ether, redispersible latex powder and other raw materials were mixed by dry force to solve the problem of large density differences and easy layering.
Wet mixing mortar: wet mixing of raw materials and water, using tanker trucks to transport the finished products directly to the construction site for construction.
Special premix: color concrete, waterproof concrete, insulation mortar, anti-cracking mortar, self leveling mortar mortar, etc., can accurately control mixing time and speed, adapt to the uniform dispersion of fiber, expansion agents and other special additives.
Ceramic industry: mixing and pretreatment of raw materials such as clay, shale and coal gangue before crushing.
4. Mining and metallurgy
Mining is a traditional area of strength for axis mixers:
Tailings Filling: The uniform mixing of whole tailings, cementitious materials and water requires very high mixing strength and concentration stability. Widened mixing area and controlled residence time of biaxial equipment can ensure that grouting concentration fluctuation is controlled to ± 1.5% or less to achieve paste filling or plaster-like filling.
Pre treatment of slurry prior to flotation: slurry is rapidly mixed with reagents such as xanthan and foaming agent to form a uniform adsorption film on the surface of fine-grained minerals (gold, copper, lead, zinc, lithium mica, etc.), directly affecting recovery.
Sludge solidification and oil sludge treatment: for sludge and sludge with high moisture content and viscosity, the biaxial extrusion push mechanism can effectively solve the problem of ``idling ''.
coal slurry, bentonite and other Viscous materials: The SJ series shaft mixer are designed specifically for this type of material, with processing capacity ranging from a few cubic meters to several dozen cubic meters per hour.
Wet metallurgy: leaching tank, purification tank tank and replacement tank in electrolysis of electrolytic zinc, copper and alumina all require stirring equipment to maintain material suspended and the reaction uniform.
5. Environmental industry
Wastewater treatment: as a feed device, it fully reacts with flocculant to make the material suspended at the bottom of accident slurry pool, lime water pool, absorption tower, etc..
Sludge treatment: Integrated treatment of municipal sludge and industrial sludge by mixing, humidifying and transporting.
Flue gas desulfurization: Stir and suspend limestone slurry and other materials in the desulfurization system.
6. Fat farming
Organic fertilizer: using livestock manure, straw powder and other raw materials mixed, biaxial continuous design, can be achieved from feeding to discharge the whole process of uniform mixing.
Compound fertilizer: accurate ratio, a variety of raw materials mixed.
Seedling substrate and nutrient soil: an even mix of light materials such as peat, vermiculite, perlite and fertilizer.
Feed processing: mixing and humidifying of various raw materials.
7. Food and drug industry
Stainless steel (304 materials) shaft mixer can meet the hygiene requirements of food and medicine:
Food: Homogenization treatment high viscosity foods such as chocolate sauce and peanut butter. High-speed dispersion can reduce particle size from a few hundred microns to a few dozen microns or less in a matter of minutes.
Pharmaceutical intermediates: antibiotic intermediates and other Chemical synthesis reactions, combined with clamps and two-stage blades, can significantly increase reaction yields.
8. Power industry
Thermal Power Plant: The humidification, mixing and loading of dry ash materials such as fly ash is one of the earliest standard applications of shaft mixers. Two-axis helical blades can transport dry powder at the same time as spraying and humidifying, so that the material does not emit dry ash or ooze water drops, and it is convenient for loading and unloading.
