What is a plow blade mixer？
The plow blade mixer is a kind of mixing equipment with a forced stirring device installed in a horizontal cylinder. The mixing device consists of a plowshare and a flying knife. Multiple sets of plowshares are installed on the main shaft, arranged in a staggered manner, and can rotate with the main shaft. Multiple sets of flying knives are installed on one side of the cylinder wall, which rotate independently at high speed and can disperse and shear materials. Because the mixer has both a plowshare and a flying knife, it is also called a plow mixer.
◆ The combination of plowshare mixer and high-speed flying knife can quickly disperse, cut and separate materials, making it more suitable for mixing materials that are prone to caking, viscosity, agglomeration when adding liquid, poor fluidity, and low-viscosity fluids.
◆ The high-speed flying knife is installed downward on the side of the mixing cylinder at an angle of 45 degrees. The cutter head extends into the barrel, and the material is driven by the plow to the effective range of the flying knife. The material is quickly sheared and dispersed by the flying knife, thereby achieving rapid mixing.
◆ The total height of the equipment is only half of the vertical mixer of the same specification, which can reduce the height of the factory building and is more suitable for direct connection with other equipment, thus reducing the equipment footprint.
◆ With more extended functions. Add nozzles, add fluid and system purge. Add a jacket to achieve multiple uses of drying and mixing. Vacuum operation, vacuum suction, solvent recovery.
Working principle of plow blade mixer
The plow mixer consists of transmission components, agitator, circular barrel, and high-speed flying knife. When working, the plowshare on the main shaft drives the material to move in a circular motion. The material is divided into two directions by the surface of the plowshare, and intersects with the material diverted by the adjacent plowshare to form a continuous vortex centrifugal material flow. The vortex centrifugal material flow continuously overlaps and disperses. When flowing through the high-speed flying knife, the fine materials boil, and the agglomerated materials are dispersed and broken by the flying knife. The material can be evenly mixed in a short time under the dual action of the plowshare and the flying knife.
Application scope of plow blade mixer
◆ Application industries: Suitable for stirring and mixing materials in pharmaceutical, food, pesticide, dye, chemical, plastic, lithium battery materials, ceramics, fertilizer, rubber plastic, mortar and other industries.
◆ Applicable materials: Various powders with specific gravity below 5g/cm³, liquid content below 20%, and certain fluidity: such as pharmaceutical intermediates, food seasoning powder, pesticides, reactive dyes, dehydrated sludge, lithium cobalt oxide batteries and other materials.
◆ Applicable process: mixing of powder and powder, powder and liquid, powder and particles, especially suitable for dispersing and mixing agglomerated powders. It is also suitable for adsorption reaction of spray liquid and powder, vacuum heating and drying and other processes.
Technical parameter
Things to note when selecting a plow blade mixer
◆ This machine is an intermittent mixing equipment. It is necessary to select the equipment with corresponding specifications according to the material processing volume of each batch and the material density, etc., so that the materials can run within the specified volume range.
◆ Select equipment materials based on material characteristics, operating conditions and hygiene level requirements. Equipment materials include carbon steel, 304/316L/321 stainless steel, or other high-hardness alloy materials. For working conditions with strong wear, surface carburizing/nitrogen, heat treatment, tungsten carbide spraying and other methods need to be adopted.
◆ Select the driving power of the equipment. Select the corresponding power configuration according to the material quantity, density, and starting method. The startup mode is divided into heavy load startup and no load startup.
◆ Expand auxiliary functions according to process requirements. Nozzles can be added for liquid injection, or jackets can be added for heating or cooling, or vacuuming for drying.
◆ Determine the design of equipment nozzles, such as feed inlet, cleaning port, exhaust port and other nozzle designs, etc.
◆ Select the discharging method. The discharge method can use butterfly valve, ball valve, flap valve, star discharge valve or knife gate valve. The driving form can be manual, pneumatic or electric.
Our advantages
We have rich manufacturing experience and strong non-standard design capabilities.
◆ The driver configuration is reliable.
The drive motor adopts international first-class brands, such as Siemens, ABB, SEW, etc. Use direct coupling, sprocket or hydraulic coupling for connection. The reducer mainly uses K series bevel gear reducer, which has the advantages of high usage coefficient, large rated torque, high transmission efficiency and low operating noise.
◆ Highly efficient mixing device
The assembled plowshare design can be quickly replaced and the gap between the cutter head and the barrel wall can be adjusted. Plowshares can be specially surface-hardened and wear-resistant, or made of high-hardness materials. Plowshare types: ordinary coulter type, serrated coulter type, scraper razor type. High-speed shearing flying knife: multi-piece cross knife, double-leaf lotus knife, and other non-standard knife head designs.
◆ Powerful supporting functions
Add a jacket with drying function. Commonly used coil steam jackets, honeycomb pressure-resistant jackets, circulating medium jackets, etc. Adding a liquid spray device is beneficial to the dispersion and mixing of liquid and powder. The liquid spray device consists of a pressure source, a liquid storage tank, a nozzle, etc. According to process needs, components such as online sampling valves, temperature detectors, weighing systems, dust removal and purification systems, and vacuum systems can also be added to expand product functionality.
