CONVEYING
Chain conveyor
The chain conveyor performs a basic function in a feed mill, carrying out the transport of cereals, flours, pellets, flakes and extrudates at any stage of the production line. Chain conveyors are ideal for covering long lengths and for the extraction of the product from underneath the hoppers.
Manufactured in carbon steel with galvanized finish or in AISI 304 stainless steel for humid environments, these conveyors offer high resistance and durability. Rosal offers a wide range of conveyors with capacities from 35 to more than 650 m³/h.
Features
Motor
Direct drive with elastic coupling
Our chain conveyors are equipped with an elastic coupling system in the transmission. This system functions as a buffer against overloads or jams, protecting the conveyor from damage and preventing unexpected stoppages. Additionally, its ability to smooth operation enhances efficiency, ensuring continuous and uninterrupted production.
Chain
Heat-treated or forged link chain
The chain is composed of high-strength links and undergoes heat treatment to significantly enhance its properties. This process increases hardness and wear resistance, resulting in greater durability and reliability even under demanding operating conditions.

Frequently Asked Questions
A chain conveyor moves material by dragging it along a closed trough using a chain. The chain, powered by a motor, runs on internal guides and continuously pushes the material from the loading point to the discharge point.
Chain conveyors are typically installed in horizontal conveying lines for raw or intermediate materials like cereals, flours, or granules. They are commonly placed between storage silos, dosing scales, mills, mixers, or truck loading systems.
Our chain conveyors are specially designed to meet the needs of the agro-industrial sector:
Compound feed mills
Cereal processing plants
Flour mills
Pet food factories
Biomass plants
Extrusion plants
Oilseed handling
Handling of cereals, flours and their by-products in general
The conveyor requires periodic maintenance at different levels, ranging from weekly cleaning to thorough overhauls every few years. Maintenance tasks include dust removal, checking and adjusting chain tension, lubricating bearings, and inspecting the electrical system. Adhering to these schedules ensures safe and efficient long-term operation.
All of our chain conveyors are certified ATEX EX II 3D T 195°C. This certification ensures the equipment is safe for use in environments with occasional combustible dust presence (zone 22). It confirms that the equipment is designed to prevent any risk of ignition, even under demanding conditions, meeting the highest industrial safety standards.
There are extractor models, designed to be placed under hoppers or silos to extract bulk materials, and conveyor models for continuous horizontal movement. In addition, they can be single or double-deckers to suit different unloading needs.
