Center Sizer Secondary Crushing Roller Sizer

Exclusive Importer & Engineering Partner in Israel: S.F.I. Engineering & Conveying Ltd.

A heavy-duty, high-performance roller sizer engineered specifically for secondary and tertiary crushing processes. The machine is equipped with an extensive range of specialized crushing caps and segments, including highly advanced tools optimized for highly abrasive or sticky materials. Product output sizing is precisely regulated via a highly adjustable gap setting mechanism. For operator safety, it features a built-in lifting device and a rigid crushing roller locking mechanism.

Core Engineering & Operational Benefits:

·         Versatile crushing segment configurations easily handle highly abrasive, wet, sticky, or clay-heavy materials.

·         Precise product sizing control via an adjustable gap-setting mechanism between the crushing segment and the rollers.

·         Integrated mechanical lifting device and crushing roller lock ensure absolute safety for operators during segment changes.

·         Low-speed, high-torque crushing action generates minimal fines and dust compared to impact crushers.

·         Rugged frame and heavy-duty bearings designed to withstand continuous, high-shock industrial crushing loads.

Expanded End-Use Industrial Applications:

Application 1: Wet Coal & Raw Potash Sizing

Raw potash and coal often arrive wet and highly adhesive, which quickly clogs traditional jaw or impact crushers, forcing frequent shut-downs for manual cleaning. The Center Sizer's dual-counter-rotating rollers grab and pull sticky materials through, while the specialized self-cleaning crushing caps shatter the lumps to the exact required size without clogging, maintaining uninterrupted power plant and chemical plant feed rates.

Application 2: Clay-Rich Cement Clinker Preparation

Cement production requires crushing hard limestone alongside highly sticky, clay-rich raw materials. Impact crushers wear out in weeks when exposed to abrasive limestone and clog instantly with sticky clay. S.F.I.'s Center Sizer utilizes highly abrasive-resistant segments that crush limestone efficiently, while its high-torque rolling action easily processes sticky clay, delivering a consistent, pre-blended kiln feed.

Application 3: High-Quality Road Aggregate Production

Producing high-grade sub-base aggregates for road construction requires tight control over particle size distribution, with minimal dust generation (fines). Traditional impactors shatter rocks, producing up to 30% waste dust. The S.F.I. Center Sizer uses compression and shear forces to crack rocks to the exact product size, reducing waste fines to under 5% and dramatically increasing quarry profitability.
