Feeders are one of the most important equipment in the crushing and grinding line, which transports raw materials uniformly and controlled to subsequent devices. Using a feeder increases productivity, reduces equipment wear and tear, and produces better quality products. Types of feeders include vibrating, grizzly, chain, and connecting rod, each of which is designed for a specific need in the mining and construction industry.
| Feeder type | Capacity (ton/hour) | Tray length (m) | Tray material | Engine type | Motor power (kW) | Grizzly shoulder | Body | Main application |
|---|---|---|---|---|---|---|---|---|
| Vibrating feeder | 10–200 | 1–6 | Steel or polyurethane | Electromotor | 3–30 | Yes | Resistant steel | Uniform transfer of materials to the crusher |
| Grizzly feeder | 20–250 | 1–5 | Steel | Electromotor | 5–37 | Yes | Resistant steel | Separation of coarse particles and protection of the crusher |
| Chain feeder | 50–400 | 2–8 | Steel | Electromotor | 7.5–55 | No | Resistant steel | Transporting heavy and large volume materials |
| Rod feeder | 10–150 | 1–4 | Steel | Electromotor | 3–22 | No | Resistant steel | Conveying materials with large diameter and uniform distribution |
A feeder is a device that feeds raw materials into a crusher in a uniform and controlled manner so that the feed flow is always consistent and consistent. Without a feeder, materials would enter the machine abruptly or unevenly, causing damage to the crusher, frequent shutdowns, and reduced equipment life. For this reason, no professional stone and quarry production line can be complete and efficient without a feeder.
The price of a feeder depends on several important factors that should be considered when purchasing. The material of the body and consumable parts are one of the most important factors. The capacity of the feeder and the type of feeder (vibrating, grizzly or chain) also directly affect the final cost. In addition, the cost of transportation and installation must be considered so that the feeder can be set up properly and without damage in the production line. The difference between a new and a second-hand feeder is also significant.
| Feeder component | Main task | Maintenance tips |
|---|---|---|
| Funnel | Collecting and directing materials to the tray | Check for cleanliness and no accumulation of material; prevent blockages |
| Tray | Moving the material over it and transferring it to the crusher | Wear control, repair or replacement in case of failure |
| Grizzly shoulder | Separation of large particles and protection of the crusher | Checking the health of the combs and cleaning them regularly |
| Bearing | Motor shaft and tray support | Regular lubrication and checking for vibration or overheating |
| Feeder body | Retaining feeder components and resisting wear | Checking for cracks, corrosion, and bolts |
In a vibrating feeder, the motor vibrates the tray and the material on it moves towards the crusher. These vibrations help the material flow continuously and regularly and prevent accumulation or sudden entry. In a grizzly feeder, in addition to transporting the material, coarse particles are separated from fine ones so that the crusher only works with the right material and the equipment is not damaged.
A connecting rod feeder uses a rod or connecting rod to guide the material. With the reciprocating motion of the connecting rod, the material on the tray is transferred to the crusher evenly and continuously. However, a chain feeder also transfers heavy and bulky material to the crusher with the help of durable chains and trays attached to it. The movement of the chain causes the material to enter the device at a controlled speed and without accumulation.
NovinCSM, with its long experience in supplying mining equipment and crushing lines, offers high-quality, long-lasting and stable performance feeders. All products are manufactured to industry standards and are supplied with after-sales service, professional installation and expert advice so that you can choose the right feeder for your production line with complete confidence.
A connecting rod feeder uses a rod or connecting rod to guide the material. With the reciprocating motion of the connecting rod, the material on the tray is transferred to the crusher uniformly and continuously. But the chain feeder also transports heavy and bulky materials to the crusher with the help of durable chains and trays attached to it. The movement of the chain allows the materials to enter the machine at a controlled speed and without accumulation.
| Selection factor | Practical tip |
|---|---|
| Type of material | Consider whether the material is heavy, abrasive, or soft. |
| Production line capacity | The feeder must be proportional to the crusher capacity. |
| Particle size | Choose the right feeder for coarse or fine materials. |
| Feeder type | Vibrating, grizzly or chain depending on application and material flow |
| Environmental conditions | Consider the temperature, humidity, and conditions of the mine or factory. |
| Installation space | The length and width of the feeder must be in accordance with the available space. |
| Maintenance and access | The feeder must be easy to service and replace parts. |
The feeder transfers the raw materials to the crusher slowly and evenly so that the equipment is not subjected to sudden stress. With the help of the feeder, the production line operates uninterruptedly and smoothly and the life of the equipment is increased.
For a jaw crusher, a vibrating feeder or a grizzly feeder are the best options. A vibrating feeder uses controlled vibration to direct the material towards the crusher, while a grizzly feeder separates out the coarse particles to prevent damage to the machine.
The capacity of the feeder is determined by the crusher capacity, weight and size of the incoming material. For example, if your crusher can process 100 tons per hour, the feeder must deliver the material to the machine in a steady, non-stop flow.
A new feeder has a longer lifespan, accurate performance, and factory support, while a used feeder has a lower initial cost but is likely to require frequent repairs and reduced productivity.
