industry characteristics

1.What are the core requirements for sand and gravel aggregates in the construction industry? (such as good particle size, continuous gradation, low mud content, etc.)

2.What type of customers are usually? (such as mixing plants, highway engineering companies, commodity sand and gravel factories)

Central state-owned enterprises' infrastructure (such as Chengtou and China Power Construction), resource-based enterprises

3.What is their biggest headache? (such as needle like exceeding the standard, unstable fineness modulus of finished sand, etc.)

solution

1.What is the recommended process for building sand and gravel?

There is no conventional process.

2. Is it necessary to configure shaping equipment (such as vertical axis impact breaking)?

Based on customer needs.

3. Dry or wet process? What scenarios are suitable for each?

The construction aggregate industry only has the concept of dry and wet methods. With abundant water resources, it is recommended to use wet methods. Wet methods are more commonly used in the south, while dry methods are more commonly used in the north.

core product

1.What are the main equipment promoted in the construction industry? (such as counterattack breaking, vertical shaft impact breaking, horizontal screen, sand washing and recycling integrated machine, etc.)

Do not recommend which equipment, only recommend suitable equipment, such as: soft rock is more commonly used for counterattack breaking, hard rock is more often used for single and multiple cylinders, high particle size requirements for upper vertical shafts, and equipment size is determined according to customer production capacity requirements.

2.Why is counterattack suitable for building aggregates? (such as good particle size and low needle like texture)

There is no such statement.

Technical Highlights

1.What technological advantages do we have in particle size control?

It's plastic surgery, repeated plastic surgery.

2.How can screening equipment ensure the continuity of gradation?

We cannot guarantee that this is a result of crushing and has nothing to do with screening. Crushing only regulates the size of the discharge outlet, roughly controlling it.

Case Reference

Do you have any cases of building aggregate projects? Such as highways, high-speed railways, and supporting facilities for mixing stations.
