Product Overview

Upgrade your fertilizer production with our Rotary Drum Screen, the essential machine for precise separation and consistent sizing of compost, organic, and compound fertilizers. This robust equipment is engineered to solve your core challenges: improving screening efficiency, ensuring product purity, and minimizing machine downtime.


Featuring a simple yet durable structure—including the drum, frame, collection hoppers, and drive system—our screen operates reliably. Material is fed into the rotating drum, where its modular screens with varying apertures accurately grade particles by size. The uniformly screened material is then efficiently discharged into respective hoppers for seamless transport.


With its innovative modular screen design, maintenance and part replacement are quick and easy, ensuring maximum uptime. Experience straightforward operation, stable performance, and a significant boost in your final product quality and overall profitability.


Why Choose Gofine Machine Drum Screen?

1. High-Efficiency Screening & Superior Purity

Solved: Inconsistent particle size and impurities in your final product.

Our Trommel features a precisely engineered mesh drum and an optimized rotational speed to ensure accurate grading of fine, standard, and coarse fertilizer materials. This results in a uniformly sized, high-market-value final product that meets strict quality standards.


2. Robust, Clog-Resistant Design

Solved: Frequent screen blockages causing downtime and labor-intensive cleaning.

The unique internal lifter flights continuously lift and tumble the material, preventing build-up and promoting a self-cleaning action. This ensures uninterrupted operation, even with moist or sticky fertilizer compositions.


3. Built for Durability & Harsh Environments

Solved: Premature wear and tear from abrasive and corrosive fertilizer materials.

Constructed from high-grade, wear-resistant steel with optional special coatings for critical components. Our Rotary Drum Screener is built to withstand the test of time, reducing maintenance costs and total cost of ownership.


3. Variable Speed Drive & Easy Adjustment

Solved: Inflexibility to handle different fertilizer types without changing screens.

Gain full control over the screening process. The variable speed drive allows operators to fine-tune the drum's rotation to perfectly match the moisture content and type of fertilizer, optimizing efficiency for every batch.


4. Portable & Stationary Configurations

Solved: Lack of mobility for multi-site operations or fixed plant space constraints.

Choose from our stationary models for permanent production lines or our mobile Portable Trommel Screen units, which can be easily transported between sites for maximum operational flexibility.

Applications for Rotary Screening Machine

This versatile machine is not just a screener; it's a vital component for quality control across the fertilizer industry:

Compost Screening: Perfect for producing clean, uniform-grade compost from municipal solid waste or green waste. (Ideal for a Compost Trommel Screen operation).

Organic Fertilizer Production: Efficiently grades fermented organic materials into high-quality, saleable fertilizer.

Compound & NPK Fertilizer: Ensures precise particle size distribution for chemical fertilizers, essential for consistent nutrient release.

Soil Amendment Processing: Screens and grades soil mixes, peat, and other soil conditioners.

It can also be used in areas such as sand gravel, cat litter, and desiccants. We welcome you to explore the potential of this equipment.

Application of Drum Screening Machine


How It Works: The Precision Screening Process

The operation of our Fertilizer Trommel Screen is a marvel of simple yet effective engineering:

Step 1:

Feed: Raw, pre-processed fertilizer is fed into the elevated hopper of the Rotary Screen.

Step 2:

Rotation & Tumbling: The material enters the large, cylindrical drum, which rotates at a controlled speed. The internal lifters pick up and cascade the material, breaking up lumps and exposing it to the screen mesh.

Step 3:

Separation: Fines and correctly sized particles fall through the screen apertures onto a fine product conveyor. Oversized materials (lumps, fibers, or undecomposed matter) are guided by the drum's slight incline to travel to the end of the Drum Screen and discharge separately.

Step 4:

Discharge: The process yields two distinct streams: a high-purity, on-spec finished product and a stream of oversize material that can be recycled for further crushing or disposal.
