This series of pumps is a multifunctional mechanical equipment for processing various materials such as fluids, colloids, and pastes, including wet ultrafine particle crushing, high shear, emulsification, dispersion, homogenization, stirring, mixing, depolymerization, and grinding. It has a wide range of applications and can replace and outperform stone mills, sand mills, ball mills, emulsifiers, shear dispersion pumps, homogenization pumps, emulsifiers, three roll machines, and tissue crushers in terms of work efficiency, as shown in Figure 1.

In this series of pumps, the functions are divided according to the internal structure: high-speed beating and mixing type, multi-functional colloid mill for grinding and beating type, and multi-functional grinder (pipeline type). The refining effect of colloid mill is generally weaker than that of high-pressure homogenizer for crushing soft drinks and other soft fluids, but it has strong adaptability to materials (such as high viscosity and large particles). Therefore, in many cases, it is used in the front of homogenizer or in high viscosity situations. Colloidal mills are often used for refinement when there are many solid substances.

The JP-W-F pump series is a split type grinding pump that is driven by a horizontal motor through a split transmission device and coupling to achieve wet grinding and other functions by high-speed rotation and complex force between the dynamic grinding disc and the matched static grinding disc. Equipment advantages: synchronous operation, pipeline connection, reasonable design, small size, good stability, automatic integration Compared with other traditional pipeline colloid mill equipment in the conventional market, such as the belt driven by the motor pulley, the main pulley reduces efficiency due to wear and slippage. In addition, if the belt pulley and pulley are prone to malfunction while the motor still operates inefficiently, it cannot be observed So the advantages of this pump compared to traditional belt driven colloid mills are obvious. And the gap between the fixed and rotating teeth can be adjusted. The processed material is pressurized by its own weight or external pressure (which can be generated by a pump) to generate a downward spiral impact force. When passing through the gap between the fixed and rotating teeth of the colloid mill, it is subjected to strong physical effects such as shear force, friction force, and high-frequency vibration, effectively emulsifying, dispersing, and crushing the material, achieving the effect of ultrafine crushing and emulsification of the material.

JP-WAD-F is a fourth generation pump, and the complete set of equipment includes: a transmission system device, a compensation device, which can flexibly adjust the spacing of the adjustment plate to emulsify fineness and prevent expansion, balance the pressure inside the container, an outlet check valve to prevent slurry reflux and internal stress generation, an inlet filter to filter and protect impurities in the slurry, a pump grinding system, a transmission device, and other functional device combinations. Its characteristics include easy operation, hygiene and environmental protection, energy saving and high efficiency, and long service life, thus achieving shock resistance, preventing impurities in processed materials to ensure material quality. It is also equipped with long-term normal operation and other performance colloid grinding pump fluid crushing equipment.

Improvement structure of split type coupling equipment: 1) The grinding system and motor are connected by a split type coupling; 2) Add a water blocking structure between the pump casing and the split type coupling; 3) When replacing the grinding disc, the adjustment disc can be disassembled without rotating it; 4) Import and export use movable installation connection method; 5) The grinding machine is made of chromium molybdenum alloy steel material. The complete set of equipment has been innovated and added in various aspects of technology, making it easy to operate and maintain, preventing motor burnout, and improving equipment performance and extending the service life.

The comprehensive performance of this series of pumps can be widely used in industries such as chemical, power, metallurgy, textile, petroleum, biochemistry, pharmaceuticals, building materials, coal, environmental protection, new energy, and new materials. Especially suitable for: titanium industry, essence, spice, medicine, medicine, petroleum, chemical industry, fine chemical industry, biological agents, plant protein, corn, animal protein, beer, food, explosives, universities, scientific research laboratories and other fields.

It can grind and transport fluids, colloids, and other slurries and pastes containing solid particles, as well as heavy medium transport. For example, the maximum allowable slurry weight concentration Cw for transportation is: titanium dioxide slurry ≤ 30%; White carbon black slurry ≤ 25%; Graphene black paste ≤ 30%; Modified silica slurry ≤ 25%; Coal slurry ≤ 45%; Slurry and heavy medium ≤ 60%.

Especially with our latest launch of the fourth generation JPW-F series grinding pump - titanium dioxide colloid mill, white carbon black beating pump - colloid homogenization grinder and other series, which are pioneering in China, our patented technology new products have been adopted and practically promoted by nearly hundreds of production enterprises and key laboratories and research institutes of universities at home and abroad, and have received high praise from experts.
