The 14th Five-Year Plan promotes rail construction, and waste cement pavement needs to be crushed and reused. Crusher includes jaw, impact, mobile, etc. After crushing, recycled concrete can be produced for use in building materials, roads and other fields, achieving a win-win situation of environmental protection and economic benefits.

In my country's "14th Five-Year Plan", provinces and cities vigorously promote rail transit construction, and in this process, the demolition and reuse of cement concrete pavement has become increasingly important. With the continuous rise in the prices of building materials such as cement, sand and gravel, more and more old cement pavements are completely broken and reused. So, what equipment is needed for cement pavement crushing? Can cement blocks be used to produce concrete after crushing?

1. What equipment is needed for cement pavement crushing?

For the treatment of waste cement pavement, cement pavement crusher is an indispensable equipment. It not only saves transportation costs, but also achieves environmental protection and resource recycling. There are many types of cement pavement crushers on the market, mainly including conventional jaw crushers, impact crushers, and new mobile cement pavement crushers. Users can choose according to specific needs.

Conventional crusher

Conventional crusher generally needs to be equipped with a complete set of production lines, including feeders, vibrating screens, conveyors and other equipment, which are suitable for processing tasks with stable sites and large scale. Although the initial investment is low, the waste cement pavement needs to be transported to the designated processing site for processing.

Jaw crusher: suitable for crushing larger pieces of cement pavement into particles of about 60 cm. The working principle is extrusion crushing. It has the characteristics of high crushing ratio, stable operation and easy maintenance.

Impact crusher: suitable for fine crushing of coarsely crushed cement blocks. It can crush them into smaller stones with excellent finished particle shape. It is widely used in construction, roads and other fields.

New intelligent model-mobile cement pavement crusher

Mobile crusher is a highly integrated design equipment. It integrates crushing, screening, feeding, conveying and other functions. It is suitable for situations where the site and raw materials are not fixed. Compared with traditional equipment, mobile cement pavement crusher has obvious advantages:

Flexible transfer: The equipment itself is equipped with a vehicle-mounted system, which can be driven directly to the raw material site and transferred at any time, avoiding tedious transportation work.

Intelligent operation: The new automatic control system supports one-click adjustment, simplifies the operation process, and reduces labor input.

Environmental protection and energy saving: The equipment produces less dust and noise during the crushing process, which helps to reduce secondary pollution and meets national environmental protection standards.

2. Can cement blocks be used to produce concrete after crushing?

After the waste cement blocks are crushed, most (about 85%) can be recycled. The crushed cement blocks can be used for a variety of purposes, one of which is to produce recycled concrete. Specifically, the crushed cement blocks can be used for:

Foundation cushion or road base: This method of utilization is more common, and the crushed cement blocks can provide stable foundation support.

Building materials: such as block bricks, permeable bricks, new wall materials, etc. These building materials not only meet engineering needs, but also have environmental protection characteristics.

After professional crushing, the finished cement blocks have uniform particle size, good wear resistance, and moderate moisture content, which meets the standards for producing high-strength concrete. In addition, waste cement blocks may also contain metal materials such as steel bars, which can also be recycled to further enhance the recycling value of resources.

3. Various ways to use waste cement blocks after crushing

Waste cement blocks can not only regenerate concrete after crushing, but can also be widely used in the following fields:

Road filler and pile foundation materials: Crushed materials can be used as filling materials or pile foundation layers in road construction, with good bearing capacity.

Building materials: Such as the production of environmentally friendly bricks, insulation materials, masonry bricks, wall panels, etc.

Scrap metal recycling: During the crushing process, waste metals (such as waste steel bars) can be directly recycled to save resources.

The crushing and reuse of waste cement pavement can not only save resources, but also reduce construction costs, achieving a win-win situation of environmental protection and economic benefits. Whether it is traditional fixed equipment or new mobile crushers, they can effectively process waste cement blocks and convert them into high-value recycled resources. With the strengthening of environmental protection policies and technological advancement, this field will have huge market potential in the future and deserves the attention of investors from all walks of life.
