Hao Stars grinding pump-pipeline colloid mill is designed with high efficiency and energy saving at the speed of 2900-3600RMP and the international standard of the country. The material is repeatedly dispersed in three to four stages between the grinding cavity and the gap between the grinding disc, rolling, shearing, grinding and crushing time. There is sufficient residence time, therefore, the smaller the flow rate of the processed materials, the better the effect, the quality is not deteriorated, and the energy consumption rate is 50-60%.
Hao Xing Grinding Pump-Pipeline Colloid Mill The tooth shape structure of colloid grinding head of colloid grinding pump is divided into primary teeth, middle teeth, fine teeth (level 3) and superfine teeth (level 4).
Calculation of linear velocity: The definition of shear rate is the relative velocity of the liquid layer between the two surfaces. Shear rate (s-1) = v rate (m/s) g fixed-rotor spacing (m) From the above, the shear rate depends on the following factors: the linear velocity of the rotor between the two surfaces under this condition The distance is the rotor-stator distance. IKN fixed-rotor separation range of 0.2 ~ 0.4 mm split pipeline colloid mill, ultra-high-speed shear is to improve the dispersion efficiency, but the shear friction coefficient is also increased by 2-4 times, easy to cause heat, slip, flow and flow rate Also increased by 2-4 times, the residence time of the material in the grinding cavity is shortened by the same multiple. The theory proves that due to the negative effects brought by high speed, friction and belt transmission, the performance of colloid grinding and grinding is relatively weakened.
Comparison of grinding pump and split colloid mill (de-funnel) only high shear efficiency: Speed and shear force: pipeline colloid mill (grinding pump), 3000/4700 RPM direct-connected motor speed determines rotor speed linear speed: V= 3.14X0.55X3000/60=9 M/SV=3.14X0.55X4700/60=14M/S Force: F=9/0.3X1000-=30000 S-1F=14/0.3X1000=42000 S-1 exit IKN high Shear colloid mill, 9000/14000RPM accelerate the linear speed through the belt: V = 3.14X0.055X90000/60=26 M/SV=3.14X0.055X14000/60=44 M/S Force: F=23/0.2X1000=115000S -1F=40/0.2/X1000=200000S-1 This is an important factor for grinding and crushing, which is equivalent to the imported split colloid mill is 4-5 times the energy consumption of grinding. Long-term use is likely to cause the shaft to be affected by heat and high-speed tampering frequency, and the shaft deformation and eccentricity will occur. The consumption of this effect cannot be ignored! !
Design and construction:
Hao Xing colloid mill equipment Hao Xing colloid mill, horizontal direct connection structure, high precision spindle, long running time, can not cause shaft deformation and eccentricity, modular design of internal structure, convenient disassembly and replacement. The friction shaft is high-shear colloid mill, which has a long running time, is not easy to cause eccentricity of the shaft, is easy to replace, and can be operated by people with ordinary product bodies.
Moreover, it is inconvenient to replace the corresponding belt clumps and belt pulleys with imported pipeline-type colloid mills to remove the funnel. It is a laborious and physically demanding labor. Let’s talk about their double-end mechanical seals. Everyone knows that they belong to Cartridge mechanical sealing device is a negative pressure method of reverse loading. If the discharge port is blocked, the pressure of the internal cavity of the imported colloid mill will suddenly rise and a leakage failure will occur. It must be operated by professional technicians.
Machinery Seal:
Hao Xing colloid mill adopts single cooling mechanical seal. Double cooling mechanical seal and improved type will never damage the shaft seal structure. The user chooses the colloid mill mechanical seal to have a large space, easy to clean, reduce leakage, and can run 24 hours, especially I The company invented the technology of the mechanical seal device of the water flushing pump shaft, the improved pipeline grinding pump-the online colloid mill can run for 10000000 hours, so that it can never be replaced. In addition, the single cooling type under normal circumstances, we use a positive pressure type mechanical seal can withstand 20 ~ 30bar pressure, according to the mechanical seal pressure is generally higher than the pressure of the sealed cavity 1-2 times the pressure, which is decided Our inlet pressure can reach 15-20bar.
Product effect: energy saving and environmental protection, fine particle size, online operation, high automation, continuous operation.
Product features: compact design, easy operation, small size, low noise, good sealing, fast heat dissipation and high precision.
Haoxing CN.HAOSTAR grinding pump-pipeline colloid grinding equipment crushing pump can be selected according to the design requirements of industrial and mining users: the following describes the modified white carbon black and titanium dioxide powder slurry has a special surface structure (with surface hydroxyl And adsorbed water), special particle morphology (small particles, large specific surface area, etc.) and unique physical and chemical properties, are widely used in many fields of rubber, plastics, coatings, medicine, daily chemical industry. However, due to the internal Silicone and the active silanol groups present on the outer surface and their adsorbed water make it hydrophilic, making it difficult to wet and disperse in the organic phase. Moreover, due to the presence of hydroxyl groups on the surface, the surface energy is large and the aggregates tend For coagulation, active coating, dispersion and depolymerization, stirring and pulping, crushing and grinding, it is beneficial to the next sand grinding and spray drying to the finished packaging.
