apron feede for limestoneBreaking system in the coarse breaking of the feed size is large, commonly used apron feeder feeder, apron feeder to breaker configuration a certain height difference, apron feeder using the discharge device into the breaker, the design angle is usually 50-60 °, due to the large height difference, angle inclination, the impact of the fall of the apron feeder to its discharge device is large, directly affecting the service life of the device. Therefore, reducing the impact of the ore on the discharge device is the main factor to improve its service life. At present, the mine mainly by increasing the wear-resistant liner to improve the service life of the apron feeder discharge device, the thickness of the ordinary wear-resistant liner 20mm, but the frequency of replacement is also higher, and the ore frequently impact on the equipment, the impact on the equipment is also greater.
Apron feeder discharge device, characterized in that said apron feeder discharge device contains a box, a left wall and a right wall, said left wall and the right wall is provided with an I-beam between, said I-beam is provided with a number of chains, said chain is connected to said I-beam through bolts, said chain is provided with a buffer steel plate respectively.
As a better example of the utility model, the said I-beam is welded to the said left side wall and right side wall. The utility model apron feeder discharge device has the following advantages: the apron feeder discharge device after adding the iron chain to slow down the impact of the ore on the device, reduce the wear on the device liner, greatly improving the service life of the device. At the same time, the impact of the ore on the device is also slowed down by adding the chain, which has a certain protective effect on the overall stability of the device. The apron feeder discharge device has a simple structure, obvious effect, low cost and high practicality.
