Product Details
With the rapid advancement of medium and high viscosity fine chemical materials such as offset printing ink, screen printing ink, concentrated ink and UV curable ink, the performance requirements for grinding equipment have evolved from basic usability to high efficiency, stability, fineness and intelligence. As the market demands finer particle size, uniform dispersion, consistent batch quality and higher productivity, traditional sand mills show obvious drawbacks when processing high viscosity materials, including low grinding efficiency, frequent clogging, difficult temperature control and complicated color change & cleaning procedures, which greatly hinder the industrial production of high-end ink and pigment products.
The global market for medium and high viscosity ink keeps expanding. Growing demands emerge for narrow particle size distribution, homogeneous dispersion and low-temperature grinding of heat-sensitive materials, especially in water-based eco ink, high-solid UV ink and nano color paste sectors. Conventional equipment suffers low grinding media filling ratio, insufficient shearing force and vulnerable separating system, resulting in long production cycle, high energy consumption and frequent maintenance. Hence, developing ultra-fine grinding machines tailored for high viscosity materials featuring high power, high rotating speed, superior wear resistance and non-clog large flow capacity has become a key breakthrough for industrial technological upgrading.
Leveraging years of technical experience and independent R&D strength in wet grinding, Longxin Intelligent launches the new-generation WSP-K high viscosity universal bead mill. Supported by patented technologies, it sets new benchmarks for ultra-fine grinding of high viscosity materials, delivering efficient, stable and intelligent solutions for ink, pigment, dyestuff and coating industries.
Innovative Structural Design for High Viscosity Materials
Adopting high-performance pin-type grinding structure and designed with centrifugal separation and annular chamber, the machine overcomes limitations of traditional disc sand mills.
- The slender grinding chamber with optimal proportion, paired with dual cooling system of rotor and stator, achieves precise temperature control. It effectively prevents gelation and deterioration caused by friction heat, perfectly suited for continuous production of heat-sensitive UV ink and high-solid concentrated ink.
- Designed with horizontal feeding and bottom discharging channel, materials flow horizontally into the chamber. Driven by high-speed pin shaft, materials fully interact with zirconia beads under intense impact and shear force. The discharge port is arranged at the chamber bottom near mechanical seal. Grinding media and materials are efficiently separated by centrifugal force, eliminating screen clogging and ensuring large-flow, non-stop and stable operation.
Working Principle: Multi-dimensional Grinding for Ultra-fine Dispersion
After startup, medium and high viscosity ink is horizontally delivered into the grinding chamber and mixed with 0.5-2.0mm high wear-resistant zirconia beads. The composite pin rotor rotates at high speed and processes materials via combined impact, shear and grinding effects.
- Centrifugal force generated by rotating pins drives intense turbulent flow of beads to crush agglomerated particles.
- Narrow gaps between pins and stator form strong shear field to split coarse particles into fine fragments.
- Mutual collision and friction among beads further refine particles to guarantee uniform particle size.
Dual cooling system operates synchronously to absorb grinding heat rapidly via circulating heat exchange medium, maintaining stable chamber temperature and avoiding composition change of heat-sensitive ink. Finely ground materials are separated from beads through self-cleaning filter screen and discharged for subsequent procedures. Grinding media flow back into the chamber under centrifugal force for cyclic grinding. The whole process realizes automatic continuous feeding, high-efficiency grinding, automatic separation and steady discharging.
