Rongda Mechanical RD-350 Feed Pellet Mill (3-5 TH)

High-Capacity Pelletizing for Large-Scale Feed Production

Introduction: Meet the Workhorse of High-Volume Feed Production

For commercial feed manufacturers and large agricultural enterprises, meeting massive daily production demands without compromising pellet quality is a constant challenge. Our RD-350 Feed Pellet Mill—with a production capacity of 3-5 tons per hour—rises to this challenge, designed to convert bulk raw materials (corn, soybean meal, hay, straw, and nutritional additives) into uniform, nutrient-dense feed pellets efficiently.

Unlike smaller mills that struggle with continuous high-volume operation, the RD-350 is built for 24/7 reliability. Its robust design balances speed, durability, and pellet consistency, making it perfect for applications like large-scale poultry feed production, ruminant feed processing, and aquatic feed manufacturing. Whether you're supplying feed to hundreds of local farms or running an integrated farm with thousands of livestock, this mill integrates seamlessly with your production line—paired with our 01Electrical Control System for fully automated operation or used as a standalone powerhouse. Let's explore how it transforms your feed production from labor-intensive to streamlined.

Key Features & Performance Advantages

The RD-350 Feed Pellet Mill is engineered to solve the unique pain points of high-volume feed production—from slow output to frequent component wear. Below are its core strengths, paired with real-world industry success stories:

1. High-Capacity Output Without Sacrificing Quality

Function: Equipped with a 350mm-diameter high-hardness die and a 11kW high-torque main motor, the mill processes 3-5 tons of feed mix per hour. Its advanced "triple-roller + concave die" design ensures even pressure distribution, producing pellets with a consistent density of 1.2-1.4 g/cm³ and size (2-10mm, customizable via die change). This consistency reduces feed waste (animals can't sort or spill pellets) and ensures uniform nutrient intake.

Industry Case: A large-scale poultry feed factory in Indonesia was using two small mills (1.5 TH each) to meet their 4-ton daily demand, leading to inconsistent pellet quality and high labor costs. After switching to the RD-350, they achieved 4.5 tons/hour output with 95% pellet uniformity, cut labor requirements by 50%, and reduced feed waste for their farm clients by 12%.

2. Heavy-Duty Durability for 24/7 Operation

Function: Critical components like the die and rollers are made of 42CrMo alloy steel,经过 precision heat treatment to a hardness of HRC 60-64—doubling the service life of ordinary steel components (up to 8,000 hours of continuous use). The mill's gearbox uses industrial-grade helical gears with a precision grinding process, reducing friction and wear even under high load, ensuring stable operation for months without major maintenance.

Industry Case: A Brazilian commercial feed manufacturer was replacing dies every 2 months with their old mill, causing frequent downtime. The RD-350's wear-resistant die lasted 6 months, reducing maintenance downtime by 75% and cutting die replacement costs by $12,000 annually.

3. Versatile Raw Material Adaptability

Function: Handles a wide range of raw material moisture levels (10-19%, optimal for pelletizing) and formulations—from high-grain feeds (corn-soybean blends for broilers) to high-fiber feeds (hay-straw mixes for cattle) and high-protein aquatic feeds (fish meal-wheat flour blends for shrimp). It also accommodates heat-sensitive additives (vitamins, probiotics) via a dedicated low-temperature feeding port, preserving nutrient integrity.

Industry Case: A Chinese aquatic feed factory needed to produce both high-protein floating feed (for shrimp) and high-fiber sinking feed (for catfish). The RD-350's adjustable die holes and additive feeding system let them switch between the two feed types in 45 minutes, eliminating the need for a second mill and saving 30% of factory floor space.

4. Semi-Automated to Fully Automated Operation

Function: Features a 10-inch color touchscreen PLC control panel, allowing operators to adjust key parameters (die temperature, roller pressure, feed rate) with one tap. It seamlessly integrates with our 01Electrical Control System, enabling full automation—connecting to raw material conveyors, mixers, pellet coolers, and sieves for a hands-free production line. Safety features include overload protection (stops the mill if foreign objects enter), emergency stop buttons, and temperature alarms to prevent overheating.

Industry Case: A US integrated farm with 10,000 cattle struggled with manual mill operation, requiring 3 workers per shift. Integrating the RD-350 with the 01Electrical Control System reduced the team to 1 operator per shift, and automated data logging let them track feed production in real time, cutting labor costs by $6,000/month.

5. Advanced Conditioning for Optimal Pellet Quality

Function: Includes a dual-chamber steam conditioning system that pre-treats raw materials with controlled low-pressure steam (85-95℃) and moisture. This process softens the material for easier pelleting, destroys harmful bacteria (e.g., salmonella, E. coli), and improves pellet binding—extending pellet shelf life to 60-90 days. The conditioning system also has a temperature and moisture sensor, automatically adjusting steam input to match raw material characteristics.

Industry Case: A European organic feed manufacturer needed to meet strict EU food safety standards (EC 178/2002) for bacterial control. The RD-350's dual-chamber conditioning system eliminated 99.5% of harmful bacteria in their feed, ensuring compliance and allowing them to export to 5 new EU countries.
