Vertical Grinding Mill

Sortek Group’s Vertical Grinding Mill (VGM, formerly Raymond mill crusher) is a high-efficiency recycling powder-making equipment for non-flammable, non-explosive materials. Engineered for construction, mining, metallurgy, pharmaceuticals, and chemicals, it is ideal for medium/small enterprises—requiring 30% less investment and 25% lower power consumption than traditional ball mills. Its core is a closed-circuit negative pressure system, ensuring dust-free operation and consistent quality.

Sortek Group Vertical Grinding Mill: Compact & Efficient Powder-Making Solution

1. Overview

Sortek Group’s Vertical Grinding Mill (VGM, formerly Raymond mill crusher) is a high-efficiency recycling powder-making equipment for non-flammable, non-explosive materials. Engineered for construction, mining, metallurgy, pharmaceuticals, and chemicals, it is ideal for medium/small enterprises—requiring 30% less investment and 25% lower power consumption than traditional ball mills. Its core is a closed-circuit negative pressure system, ensuring dust-free operation and consistent quality.

2. Core Advantages

Sortek Group’s VGM stands out with optimized design:

Compact Integration: Vertical structure saves 40% footprint, integrating feeding, grinding, and packaging as an independent system.
High Precision: Screening rate over 99% (surpassing standard mills) via Sortek’s classification technology.
Durability: Critical parts (rollers, rings) use high-grade alloy castings, extending service life by 50%.
Eco & Cost-Effective: Negative pressure control reduces dust emissions; maintenance-friendly modular design cuts operational costs by 20–30%.

3. Working Principle

Streamlined, automated process by Sortek Group:

Raw materials are pre-crushed to size, then fed into the grinding chamber via electromagnetic vibration feeder.
Rollers press against the grinding ring (centrifugal force), while shovels feed materials for pulverization.
Ground powder is carried by airflow to the analyzer—fine powder is collected by cyclone separators, coarse powder regrinds.
Hermetic negative pressure system prevents dust leakage.

4. Key Components

Sortek Group’s VGM integrates synergistic core parts:

Grinding Unit: Wear-resistant alloy rollers/rings, heavy-duty cast iron housing, and accessible inspection doors.
Classifier: Whizzer-type design with adjustable RPM for fineness control (higher RPM = finer powder).
Cyclone Separator: Steel-built, paired with airlock valves for air-powder separation and continuous discharge.
Centrifugal Blower: Balanced impeller for stable airflow; dust collector captures residual particles.

5. Applications & Optional Support

Scope: Processes 280+ materials (hardness ≤7 Mohs, humidity ≤6%), e.g., cement, limestone, activated carbon, and pharmaceutical excipients.
Optional System: Sortek’s Denseveyor pneumatic conveying system (PLC-controlled) for automated powder transport to silos, enhancing integration.

Backed by Sortek Group’s after-sales support, it delivers reliable performance for cost-sensitive, efficiency-focused enterprises.
