Vibrating feeder

The feeder can be used in a variety of quarry applications. It can transfer materials from silos, bins or stockpiles to crushers, screens and conveyors at a certain rate. It can also reduce the impact of materials on equipment and extend equipment use life.

There are many types of feeders in the quarry to meet specific applications. Even in the same material crushing processing plant, different material processing stages require different feeders. This article will discuss the most common types of feeders used in quarry applications.

Pan feeder

Pan feeder

The Pan feeder is powered by two vibration motors and has a variable speed control device that can adjust the feeding speed. It is specially designed for high-capacity feeding and is widely used in aggregate production, mining operations and recycling applications. It is used to continuously and uniformly feed materials in transfer bins or pre-storage areas into secondary or tertiary crushers, or use Feed materials to the belt conveyor in the adjustment yard.

The Pan feeder can be installed on a static frame or suspended from the outlet of the silo, and supported by a heavy-duty rubber mount or spring. Generally, after coarse crushing, the storage yard is adjusted to feed the belt conveyor. Because the pressure of the warehouse is relatively large, the pan feeder should be installed on the static frame. And the transfer silo feeds to the secondary or tertiary crusher and the belt conveyor, which can choose the suspended installation method.

The installation angle of Pan feeder can be selected between 0-10°.

Vibrating grizzly feeder

Grizzly feeder for sale

Grizzly feeder is designed for super heavy duty conditions and can be used for mobile, portable and stationary operations. It can adapt to harsh initial feeding conditions such as large warehouse pressure, high load, and large impact. The maximum processing capacity is 1600tph, and the maximum feeding size is 1.5m, which can meet the maximum pressure of the silo below 80m³. It is suitable for feeding jaw crushers and primary impact crushers.

Grizzly feeder has a pre-screening function and can provide 1, 2, 3 and 4 bars to meet different application requirements.

Grizzly bars

The opening of the grizzly bars can be adjusted within the range of 80mm-200mm. In Optional hanging screen layer, the screen hole is about 10-30mm, to meet the requirements of soil removal for skin mining (the material should be removed before entering the primary crusher), and it can also effectively remove smaller than the CSS of the crusher fine material greatly reduces the load of the initial crusher.

Belt feeders

The feeding of a belt feeder is similar to a belt conveyor. When the material in hopper, silo or stacking hopper needs to be transferred to a vibrating screen, crusher or conveyor belt at a controlled feeding speed, the belt feeder is usually selected.

Unlike the belt conveyor, the belt feeder uses a collecting hopper instead of a guide trough. The front end of the belt feeder is equipped with an adjustment baffle to limit the cross-sectional area of ​​the material passing through the collecting hopper. Combined with speed adjustment, the material can be guaranteed Continuous supply.

The belt conveyor is also equipped with anti-overflow skirts and skirt conveyor belts throughout the entire process to prevent material overflow.

Plate apron feeders

Plate apron feeders

The apron feeder is suitable for various applications that are too harsh for other types of feeders, including suitable for processing materials containing large, heavy or sharp lumps. It is suitable for materials that must be able to withstand the impact of heavy materials falling from a certain distance, and for receiving and conveying materials that may damage other types of feeders, such as wet, viscous, dry or hot materials.

The apron feeder is usually installed under the stock pile or silo to feed the material to other systems at the specified feeding speed.
