Double Roller Press Granulator for Compound Fertilizer Production Line

Overview

The Double Roller Extrusion Granulator, also known as a Dry Granulation Machine or Roll Press Compactor, is an advanced industrial equipment designed for transforming fine powders into dense, uniform granules without liquid binders. This machine utilizes Roll Press Compaction technology, where two synchronized, counter-rotating rollers apply extreme mechanical pressure to force raw material through precisely designed molds.

In the modern fertilizer manufacturing industry, reducing energy consumption and operational costs is paramount. The Double Roller Press Granulator is engineered specifically as a premium dry granulation solution for compound NPK, ammonium sulfate, and potassium chloride fertilizer production lines. Operating entirely at room temperature, this advanced equipment completely eliminates the need for fuel-consuming drying and cooling processes, allowing fertilizer plants to significantly cut down on initial capital investment and daily utility costs.

Through intensive, high-pressure extrusion between two synchronized counter-rotating rollers, loose powdery formulations are instantly compacted into dense sheets and subsequently broken into uniform, high-strength spherical or oblate granules. The rollers are forged from premium, wear-resistant alloy steels, meticulously treated to withstand the highly abrasive and corrosive nature of chemical mineral salts. As a dedicated factory supplier, Gofine Machine delivers this highly efficient granulator to integrate seamlessly into automated compound fertilizer lines, providing a dust-free, continuous, and high-yield operation that maximizes long-term profitability.

Key Features

Dry Granulation Process: Produces granules without moisture or liquid binders, eliminating drying steps and saving energy.
High Pressure Roller Compaction: Robust rollers with hydraulic/spring system deliver high compression for hard, dense granules.
Excellent Material Densification: Increases bulk density, improving storage/transport efficiency while reducing dust.
Continuous Operation: Designed for high-throughput production with stable output quality and minimal operator needs.
Versatile Processing: Handles fertilizers, chemicals, minerals, and industrial powders with customizable granule sizes.
Eco-Friendly Design: Closed system minimizes dust pollution and avoids wastewater generation.
Durable Construction: High-wear-resistant materials ensure long service life with low maintenance requirements.

Applications

This versatile machine serves multiple industries:

Fertilizer Granulation: Produces compound, NPK, and organic-inorganic fertilizers from materials like ammonium chloride and potassium chloride.
Chemical Processing: Granulates pigments, dyes, resins, pesticides, and insecticides to improve flowability.
Mineral/Metal Industry: Agglomerates metal powders, coal fines, carbon black, and ores for improved handling.
Pharmaceutical/Food: Used where dry granulation improves compression for tableting or powder flow.
Other Industries: Ceramics, refractories, and industrial by-product recycling applications.

Working Process

Feeding: Powder material uniformly fed into hopper via screw conveyor.
Compaction: Material enters gap between counter-rotating rollers.
High-Pressure Extrusion: Rollers exert extreme pressure, compacting material against mold cavities.
Sheet Formation: Material exits as dense, patterned sheet/ribbon.
Crushing/Sizing: Sheet broken into fragments and screened for uniform granules.
Recycling: Fines/oversized particles returned to feeding system.
Output: Uniform granules discharged as final product.

For enhanced granule quality, this equipment can be paired with a spheroidizing machine for spherical shaping or integrated into complete automated production lines.
