Product Description
Double Roller Extrusion Granulator – Wear-Resistant & Low-Downtime Granulation for Abrasive Materials
Product Overview
The Double Roller Extrusion Granulator is a rugged, high-performance dry-type granulation machine engineered exclusively for processing abrasive, high-hardness powdery raw materials. This machine features reinforced structural design and ultra-wear-resistant roller components to achieve stable, continuous granulation via high-pressure extrusion (1-25MPa). It requires no water, chemical binders, or drying processes, and can directly convert abrasive powders into dense, high-strength pellets with a forming rate exceeding 93%. With production capacity ranging from 2-40t/h, it is the ideal core equipment for heavy-industry scenarios demanding long-term, low-maintenance operation with minimal downtime.
Application Scope
- Building Materials Industry: Granulation of quartz sand powder, corundum powder, cement clinker, and refractory aggregate—producing pellets with high compression strength for refractory and construction applications.
- Chemical Industry: Processing of abrasive inorganic salts, mineral powder additives, and ceramic powders—ensuring stable production without frequent component replacement.
- Fertilizer Industry: Granulation of high-hardness compound fertilizer raw materials, potassium sulfate powder, and phosphate rock powder—reducing equipment maintenance costs for large-scale fertilizer plants.
Key Features & Benefits
- Ultra-Wear-Resistant Roller Design: Rollers made of high-chromium alloy steel (HRC ≥65) with 5mm surface hardening treatment, providing 3x more wear resistance than standard rollers. For abrasive materials like iron ore powder, roller service life exceeds 15,000 hours—reducing replacement frequency by 70% and significantly cutting maintenance costs.
- Reinforced Structure for High-Pressure Extrusion: Machine frame welded with thickened manganese steel plates and transmission system with heavy-duty gears and bearings to withstand high impact forces. Stable operation under maximum pressure of 25MPa, producing pellets with compressive strength ≥4MPa resistant to crushing during transportation and use.
- Low-Downtime Operation & Easy Maintenance: Quick-change roller sleeve structure enables replacement within 1 hour without disassembling the entire machine—reducing maintenance downtime by 80% compared to integral roller models. Automatic roller cleaning scraper with wear-resistant tungsten steel head prevents material adhesion and avoids roller jamming.
- Binder-Free & Water-Free Granulation: No chemical binders or water addition eliminates raw material costs for additives and energy costs for drying. Dry-type process avoids equipment corrosion caused by moisture, extending overall machine service life by 50% compared to wet granulation equipment.
- Highly Adaptive to Abrasive Materials: Handles materials with Mohs hardness ≤6 and moisture content of 2%-16% without pre-processing steps. Adjustable pressure and speed system ensures stable forming rate and uniform particle size (1-15mm customizable).
