Product Principle
Fine-pulverizing pump main structure
The Fine Grinding Pump is designed and manufactured with a three-stage grinding area, including an intake shearing zone, a crushing zone, a grinding zone, and a refinement zone on the rotating stator. The flat shearing and crushing distance after the rotating stator is merged is generally 0.05mm (the adjustable distance between rotating stators is 0.01-2mm), with a large outer diameter of up to 600mm, high linear speed up to 120m/s, and normal conveying head up to 3-6 meters, with a maximum of 50 meters.
Fine Grinding Pump Main Function
Fine crushing pumps are primarily used for the crushing and grinding of various fragile particles such as crystals, lumps, agglomerates, sticky blocks, and filter cakes suspended in pipeline fluids. They enhance energy efficiency in the material reaction process and ensure the smooth flow of subsequent pump valves. During the crushing and grinding process, the fluid must pass through a shearing zone, three grinding zones, and undergo ten stages of dispersion and refinement before being curved extruded through a channel with approximately 0.3-0.6mm teeth, creating a high-speed, high-pressure, and high-frequency atomization phenomenon. This effectively improves the particle crushing, dispersion, and emulsification capabilities.
Fine Crushing Pump Working Principle
High-speed rotating motors propel the material directly into the high-shear crushing zone from the inlet, where a special crushing device rapidly breaks down large lumps, sticky masses, and other large particles within the fluid. The material is then drawn into the shearing crushing zone, where intense friction and grinding occur due to the high-speed cutting action of the rotor and stator blades in a very narrow working passage. Under the influence of mechanical motion and centrifugal force, the finely crushed material is repressed back into the fine grinding zone for further grinding and crushing. The fine grinding zone is divided into three stages, with each subsequent stage extending outward featuring higher blade precision, smaller pitch, longer linear velocity, and finer material after each grinding. Simultaneously, the fluid gradually extends in a curved radial direction. At each stage, the direction and speed of the fluid change instantaneously, and it undergoes millions of high-speed shearing, intense friction, compression grinding, and particle crushing per minute. After millions of high-speed shearing and grinding in three fine grinding zones, the liquid material achieves the effects of molecular chain breakage, particle crushing, and liquid-particle tearing, fully achieving the goals of dispersion, crushing, emulsification, homogenization, and refinement. The fineness of the liquid material can reach 0.5 μm, and the normal conveying height can reach 3-6 meters.
Note: Users provide material property parameters, or bring materials to the production base for on-site testing. Manufacturers select the internal structure of the grinding disc based on the medium characteristics.
