Why Precision Grinding Is Required

Coarse particles and poor dispersion in slurry directly degrade end‑product quality

Ink Printing Industry

Coarse pigment particles in lab‑formulated inks cause uneven hue and poor color development, compromising formula evaluation accuracy. Three‑roll grinding disperses pigments to micron level for uniform hue, excellent color performance and reliable, reproducible test results.

Cosmetic Industry

Grainy texture in lipsticks, foundations and other pastes impairs spreadability and gloss for poor consumer experience. Three‑roll grinding delivers smooth fine pastes to enhance product quality and market competitiveness. End‑product performance can be verified via small‑batch trial runs.

Electronic Paste Industry

Silver‑powder agglomeration in conductive silver paste triggers screen‑printing breaks and sheet‑resistance fluctuation, undermining electronic‑device consistency. Three‑roll mill achieves uniform silver‑powder dispersion for stable sheet resistance and continuous screen printing, enabling accurate lab formula assessment.

✨ ### Dilemmas of Traditional Grinding Methods High-speed dispersors commonly used in laboratories only achieve dispersion instead of real grinding, failing to meet fineness requirements. Sand mills produce abrasives from grinding media, introducing impurities and contaminating precious sample materials. Manual grinding suffers from low efficiency and poor consistency, with inconsistent results from different operators for the same material.

Why Choose SIE‑SG50

Solves Core Pain Points of Laboratory Small‑sample Grinding

Micron‑level Precision Grinding

Rolls are precision‑ground with high parallelism, maintaining consistent gap clearance along the full roll length. The matte roll surface ensures good slurry adhesion. Large‑interference cold‑press fitting is adopted for shaft ends at both sides for firm and stable connection. Finer particle size can be obtained by cyclic grinding to satisfy strict fineness requirements for R&D.

Precise Speed Control via DC Governor

DC motor with adjustable‑speed governor. Grinding speed can be flexibly set according to material viscosity and target fineness. High‑speed grinding boosts efficiency for low‑viscosity materials; low‑speed grinding ensures uniform dispersion for high‑viscosity materials. Power is transmitted via V‑belt and gear train to drive slow, middle and fast rolls for stable and reliable transmission, delivering precise and repeatable grinding results.

Compact Benchtop Footprint

Designed for laboratory benchtop use. Small footprint and easy mobility for flexible layout in limited lab space. No special foundation required; ready‑to‑run upon power‑on. Removable copper feed knife facilitates cleaning and quick material changeover.


✨ If your lab requires a compact, easy‑to‑operate three‑roll mill with micron‑level grinding fineness, the SG50 is your ideal choice.

Working Principle

It achieves mixing and homogenization by forcing material under compression and shear through three rollers rotating at different speeds.

Step 1: Three‑roll Shear Grinding
The base‑mounted motor drives the transmission shaft via V‑belt. The transmission‑shaft gear drives the fast‑roll gear, which further drives the middle‑roll gear, and then the middle‑roll gear drives the slow‑roll gear to form a complete transmission system. Three rollers rotate toward each other at a 1:2:4 speed ratio. Slurries are subjected to forced compression and shear within roller gaps, undergoing progressive grinding and dispersion from slow roll to middle roll and then fast roll.

Step 2: Gap Adjustment for Particle Size Control
Turn the handwheel to compress or release springs, moving fast and slow rollers forward or backward to adjust roller gaps and control grinding fineness. Materials are refined progressively from feed roll to middle roll and discharge roll. Various target fineness can be achieved by adjusting gaps via handwheel.

Step 3: Blade Discharge for Material Collection
A scraper blade is mounted on the discharge knife plate and closely fits the fast‑roll surface slightly above the roller center. It smoothly scrapes off finely ground material adhered to the fast‑roll surface for collection. Circulated grinding can be performed repeatedly to reach target fineness.


Simple three‑step workflow: Three‑roll shearing → Gap‑based particle control → Scraper discharge. Progressive grinding reaches 3‑18μm. Internal water‑cooling channels inside rollers adjust water flow via cooling pipes to suppress temperature rise during dispersion and guarantee grinding quality.
