Fortified Mechanical Power for Demanding Applications.
ZLY Hard-Tooth Gear ReducerFortified Mechanical FrameEnhanced Power TransmissionThe SZ enhanced three roll mill is engineered for high-viscosity/high-hardness material grinding, bridging the tech-nological gap between S and SQ models. It excels in processing specialty compounds like silicone rubber, blue foam, pencil cores, and reflex blue paste. Enhanced three roll mill key advantages include customizable motor power and reducer configu-rations for ultra-stable operation, enhancing energy efficiency while reducing maintenance costs.
The Heavy-Duty Mechanical Workhorse
When your materials push standard mills to their limits, but you don't require the absolute maximum extremes of our SGQ series three roll mill , the SZ enhanced series three roll mill provides the perfect middle ground.
Upgraded from the standard SG models, the SZ series three roll mill features a significantly strengthened chassis and is driven by a ZLY hard-tooth surface gear reducer. This mechanical enhancement guarantees slip-free, high-torque transmission, ensuring stable operation under heavy loads.
ZLY Gear Transmission
Utilizes industrial-grade ZLY gear reducers to deliver higher torque and eliminate the power loss and slipping commonly associated with standard belt-driven mills under heavy loads.
Deep-Chilled Cast Iron Rollers
Enhanced three roll mill equipped with premium chilled alloy rollers that offer superior surface hardness and wear resistance, extending the lifespan of the equipment.
Reinforced Manual Adjustment
Heavy-duty handwheels and reinforced screw threads allow for precise and stable gap adjustments that hold their position even during aggressive milling on an enhanced three roll mill.

Industrial PaintsHeavy-duty anti-corrosion paints.
Thick InksHigh-viscosity printing inks and pastes.
Putty & FillersAutomotive body fillers and industrial putties.
For standard inks and light paints, no. However, if you are processing heavy-duty pastes, putties, or high-solid coatings, the ZLY reducer prevents belt slippage and ensures 100% torque transmission from the motor to the rollers.
The SZ is fundamentally designed as a robust mechanical machine. If you anticipate needing hydraulic pressure control in the future, we highly recommend starting with our SY or SYS series.
A three roll mill is widely used for grinding, mixing, and dispersing high-viscosity materials such as inks, paints, pigments, adhesives, cosmetics, and advanced composite materials.
A three roll mill achieves fine particle dispersion and uniform mixing through adjustable roller gaps, helping manufacturers improve consistency, smoothness, color quality, and overall performance of final products.
Selecting a three roll mill depends on material viscosity, production capacity, roller size, processing requirements, and application fields to ensure efficient and stable manufacturing performance.
