The following are methods to improve the output and efficiency of sand and gravel aggregate production lines:

I. Equipment Selection

The success of a sand and gravel aggregate production line largely depends on reasonable equipment selection, generally determined by factors such as material hardness, soil content, and corrosivity index.

Some production line investors do not consult reputable design firms or simply copy equipment selections from other companies, which may not suit their actual production needs, leading to problems such as unreasonable equipment selection.

This problem is difficult to completely solve even with process adjustments. Only by replacing the crusher with an extrusion crusher, such as a cone crusher, can the stable operation and sustainable development of the production line be ensured.

II. Material Transfer Drop

1) There are two main points causing drop in material transfer and conveying: the inlet of the vibrating screen and the outlet of the coarse crusher. When the material enters the vibrating screen, the large drop between the two inevitably causes a certain degree of impact on the screen plate, thus causing wear.

Improvement Measures:

2) Adjust the allowable distance appropriately to reduce wear on the screen plate, or install used conveyor belts in the initial impact area of the vibrating screen plate to reduce material impact on the screen plate.

Coarse crushing equipment usually has a concrete foundation, with a significant drop between the discharge port and the conveyor belt. The discharge from coarse crushing can cause wear on the conveyor belt and even damage the buffer rollers.

Improvement Measures:

A buffer bed can be used instead of the buffer rollers to reduce the impact and wear of material on downstream equipment. Furthermore, in cases of extreme drops, if there is sufficient space for equipment layout, additional buffer devices can be added to mitigate the impact and reduce equipment wear caused by the drop.

III. Material Chute Wear

Sand and gravel aggregates have multi-faceted characteristics, and some materials have a certain degree of abrasiveness. Combined with the large drop during material transport, this shortens the service life of the material chute and leads to severe wear and impact.

Improvement measures:

Insert lining plates inside chutes subjected to high impact forces; for chutes subjected to lower impact forces, thicken the chute steel plates as much as possible to allow material grinding to occur inside the chute. This design should be avoided for materials prone to clogging.
