High-Efficiency Dispersion + Flexible Adaptation: How The Three Roller Grinding Mill Becomes The Core “Makeup” Equipment For Quality?
2025-12-15 17:15
In the cosmetics industry chain, eyebrow pencils, as a core category for facial shaping, must meet strict industry technical standards and consumer usage demands. From formula design to finished product delivery, a high-quality eyebrow pencil must possess four core indicators: paste uniformity, stroke smoothness, color stability, and structural integrity, while avoiding quality defects such as frosting or shrinkage of the core after prolonged storage

Does Your Production Line Also Face These Challenges?
- Uneven color payoff and color difference: Pigment agglomerates are not fully broken down, resulting in inconsistent line darkness and inability to achieve precise application.
- Excessive paste granularity: Solid particles from incomplete grinding increase the friction coefficient between the core and skin, causing discomfort and potentially clogging pores, posing a safety hazard.
- Poor system stability: Uneven mixing of oil-wax base materials and pigments leads to paste stratification, causing issues like clumping or breakage in the finished product, reducing its lifespan and market acceptance.
- Low process adaptability: Traditional equipment with fixed parameters struggles to adapt to the requirements of different formulas, ranging from high-hardness wooden eyebrow pencils to soft, automatic eyebrow pencils.
The core solution to these problems lies in key equipment capable of achieving ultimate raw material dispersion and precise process control. ZYE's three-roll mill, with its 1μm grinding and dispersion capability, along with freely adjustable roll gap and speed ratios, can effectively address these challenges.
ZYE: Infusing A "Silky Soul" Into Every Eyebrow Pencil
ZYE's three-roll mill utilizes high-speed shear forces between the rollers to achieve micron-level (even nano-level) breakdown of pigment agglomerates, ensuring each pigment particle is perfectly encapsulated by the oil-wax base, solving the aforementioned problems at their root.
Precise Process Adaptation, Empowering Production Of All Eyebrow Pencil Types
For high-wax-base formulas, precise roll gap control enables powerful shearing, ensuring uniform pigment distribution in high-viscosity systems and producing a dense, break-resistant core. For high-oil-content pastes, optimized speed and pressure maintain ultimate dispersion while preserving the paste's spreadability and smoothness, resulting in excellent stability after mold casting.
Flexible Adjustment Of Core Parameters, Unlocking Formula Innovation Potential
Through a digital control system, you can freely adjust roll gap, speed and speed ratios, and temperature control based on formula characteristics.

Compared to traditional equipment like ball mills or colloid mills, the three-roll mill offers significant advantages in eyebrow pencil manufacturing: high dispersion efficiency, controllable grinding precision, and strong material adaptability, making it the core equipment for unlocking the quality code of eyebrow pencils.

Traditional Three-Roll Mill | Precision Three Roller Grinding Mill
As consumer demands for cosmetic product quality continue to rise (e.g., natural ingredients, sensitivity-skin compatibility, long-lasting wear), eyebrow pencil manufacturing will develop towards formula refinement, process intelligence, and production sustainability. In the future, the three-roll mill will not only be the "quality cornerstone" of eyebrow pencil manufacturing but also a core force driving the refinement and intelligent upgrade of the entire cosmetics industry, helping companies achieve exceptional performance in fierce market competition.
