Sand and gravel is the largest, indispensable and irreplaceable raw material for infrastructure construction in my country, with an annual consumption of about 20 billion tons. It is the world's largest mineral product, raw material and bulk commodity. In the early days, the natural sand and gravel resources of the river were mainly exploited. With the tightening of natural sand and gravel resources and the strengthening of environmental protection, machine-made sand and gravel have gradually become the main source of construction sand and gravel in my country, and its proportion has now accounted for more than 80%.

sand and gravel crushing production machine

Configuration plan of 300 tons per hour machine-made sand and gravel production line?

1. Configuration of production line for medium and below hardness materials

Mohs hardness: ≤5

Representative materials: limestone, calcite, feldspar, quartz stone, etc.

Equipment recommendation: Jaw Crusher + Impact Crusher

The Jaw Crusher can deal with the coarse crushing of large materials. It adopts the principle of extrusion and crushing. The movable jaw and the static jaw form a "V"-shaped crushing cavity. The large materials are swallowed and crushed like a tiger chewing. Good and broken ratio is large.

The Impact Crusher adopts the principle of impact crushing. The material is repeatedly crushed and ground in the crushing chamber, and the finished product has a good particle shape and uniform particle size. It is a fixed old partner with the Jaw Crusher, and is mainly used for fine crushing of stone materials.

2. Configuration of hard material processing production line

Mohs hardness: 5-16

Representative materials: granite, basalt, marble, pebbles, etc.

Equipment recommendation: Jaw Crusher + Cone Crusher

The Jaw Crusher performs primary crushing of bulk materials, and the Cone Crusher is matched with it for secondary crushing. The overall wear resistance of the Cone Crusher is good, the failure rate is low, and the principle of lamination crushing also makes it very suitable for hard materials. , Compared with the Impact Crusher, although the initial investment cost is higher, the durability of the whole machine is strong, and the later investment will be reduced.

Configuration scheme of machine-made sand and gravel production line (taking granite as an example):

Feed size: ≤800mm

Finished product specifications: 0-5mm, 5-10mm, 10-30mm

Equipment configuration: raw material warehouse, Vibrating Feeder, Jaw Crusher, Cone Crusher, Vibrating Screen

The sand and gravel aggregate processing industry is developing towards industrialization, standardization and greening, and the market and policy environment of machine-made sand and gravel have good prospects. Adequate market demand research, reasonable design plans that meet product characteristics requirements, and active control of construction and production processes are important means of cost control for machine-made sand and gravel production.

In order to plan a mechanism sand production plan that is more in line with your expectations, it is recommended that you compare with equipment manufacturers and choose the plan and configuration you want. If you want to learn more about the configuration information of machine-made sand and gravel production, you can consult Anhui Meilan Mining Machine online, or go to the factory for on-the-spot inspection and understanding.
