Cobblestone is an accessory product of mining yellow sand, named because it looks like a cobblestone. The quality is hard, the color is bright and simple, and it has the characteristics of natural stone that is resistant to compression, wear, and corrosion, so it is a frequently used green building material. At the same time, it is also an ideal raw material for machine-made sand, which is widely used in construction, decoration, gardening, sewage treatment, and other fields.

The cobblestone must first be roughly crushed by the jaw crusher, and the advantages of high output and large crushing ratio of the jaw crusher are fully exerted at this stage. Secondly, a fine jaw crusher or impact crusher can be used, both of which are commonly used equipment for fine crushing, and users can choose flexibly according to their needs. The coarsely broken pebbles are further broken into fine particles. Third, the pebbles need to be finely crushed and shaped. This stage is an important part of the process of machine-made sand. It is necessary to use sand making machine to shape the finely crushed pebbles so that the particle size meets the requirements of machine-made sand and the grain shape is beautiful. It is then screened by a vibrating screen, and those that do not meet the requirements are returned to the sand-making machine for fine crushing, and the particles that meet the standards are transported to the transfer area. After cleaning the finished product, after being cleaned by the sand washing machine, the process flow of the cobblestone machine-made sand is basically completed, and it is transferred by the belt conveyor to the storage pile, which is the finished sand?

Outstanding advantages

1. Better grading

In the cobblestone sand production line, the mud powder in the artificial sand can be removed by the powder separator to meet the standard of construction sand, and the content of the stone powder in the artificial sand can also be controlled to be within the range specified by the state, thereby improving the sand production. stone standard.

2. Reduce production and maintenance costs

Compared with other production line equipment, it is relatively convenient maintenance and operation method. Compared with other production line equipment, it is easy to maintain and maintain. The wearing parts are currently made of new high-strength wear-resistant materials in China, with small loss and long service life, which can bring considerable economic benefits to customers.

3. High degree of automation

Fully automated operation process, higher production efficiency, more optimized work efficiency, high degree of automation, large crushing ratio, high production efficiency, large processing capacity, the crushed product is cube-shaped, with low needle-like content, no internal cracks, Engage in high compressive strength.

4. Wide range of applications

It has been successfully used in the crushing and processing of limestone, basalt, granite, cobblestone, and other rocks, and the quality of the finished products after crushing has reached the standard, providing qualified aggregates for industries such as highways, railways, water conservancy, and concrete batching plants.
