The development history of global pigment grinders
The first generation of pigment grinders (1930s-1970s):
The first generation of grinders was dominated by three-roller grinders. Due to the technical reserves at that time, this type of grinder relied on manual adjustment, with low efficiency (≤50kg/h), uneven grinding particle size and coarse particle size (D50≥10μm).
The second generation of pigment grinders (1970s-2010s):
Sand mills were successfully developed and popularized, achieving partial automation, and the grinding particle size was reduced to 1-5μm. The energy consumption of the equipment was still high (≥1.2kWh/kg). The third generation of pigment grinder (2010s-present):
Tianchuang has developed the latest intelligent nano-grinder:
Grinding particle size exceeds 100nm
Mechanical energy consumption is reduced by 40%
The latest technical parameters of Tianchuang pigment grinder

Processing capacity 0.5-100kg/h (continuous) The production capacity of similar products is increased by 30%
Discharge particle size D50: 100-800nm (equipment adjustable) Breaking through the upper and lower limits of traditional ball mills
Grinding media 0.1-0.3mm zirconium oxide balls (optional and can be used in combination) Wear rate <0.001kg/t>
Temperature control accuracy ±1℃ (optional circulating water cooling system/liquid nitrogen cooling system) Effectively control the quality change of heat-sensitive pigments
Energy consumption 0.8kWh/kg Meets energy-saving standards
Intelligent system 6-inch touch screen Reasonable adjustment of grinding parameters
Application scenarios of pigment grinder
Industry Typical pigments Tianchuang solutions
Ink Phthalocyanine blue, carbon black Nano-processing (D90≤300nm) to improve printing gloss
Coatings Titanium dioxide, pearlescent powder Narrow distribution grinding (D90/D10≤1.8) to prevent sedimentation
