Aggregate is a granular loose material that acts as a skeleton or filling in concrete. It is called aggregate because it acts as a skeleton and support in the building, just like the bones of the human body. When mixing, the cement becomes a thin paste when mixed with water. If no aggregate is added, it will not be able to form and will lead to unusable. Therefore, aggregate is an important raw material in construction.

Coarse aggregate: also known as pebbles, refers to aggregates with a particle size greater than 4.75 mm, mainly pebbles and artificial crushed stones. Pebbles are nearly round or elliptical rocks that are naturally formed by natural weathering or water transport. Crushed stones It is mainly made by mechanical crushing and screening. According to its use, the raw materials can be limestone, bluestone, river pebble, granite, basalt and other rocks.

Fine aggregate: also known as sand, refers to aggregates with a particle size of less than 4.75 mm, mainly sand and artificial sand. Sand is river sand, lake sand, mountain sand and desalinated sea sand, etc.; artificial sand undergoes sand making The machine breaks the rock into particles like natural sand, and its raw material is like crushed stone. Various types of rock can be selected according to its purpose.

XKJ Group's aggregate production line is to feed the crusher through a feeder, crush the material in the crusher, and then pass the conveyor belt to the vibrating screen and then screen out the finished material.  It is not only reasonable in design, but also in maintenance. With low cost and equipment, it has a good reputation among users in the mining industry.

1.In the design of the sand and gravel production line, sand and gravel equipment, due to the reasonable matching of the crushing equipment at all levels and the rigorous spatial cross layout, it has a small area and high investment and economic benefits;
2.The quality of crushed stone is good, and the output rate of stone powder is low;
3.At the same time, it is equipped with an advanced electronic control operating system to ensure the smooth discharge of the entire process, reliable operation, convenient operation and energy saving.
