Cobblestone is a common type of stone, so named because it resembles a cobblestone. About 96% of the pebbles are silicon dioxide (SiO2), and the main component of natural sand is also silicon dioxide. Using pebbles to produce machine-made sand is equivalent to a "reduction reaction".
Cobblestones are widely distributed and resources are relatively easy to obtain. The middle and lower reaches of the Yangtze River are rich in resources, mostly sedimentary; the north includes Shandong, Liaoning and other places, and the south includes Guizhou, Chongqing, Guangxi and other places, with large reserves of cobblestone resources, each with its own characteristics and rich varieties; Due to historical reasons, the resources of cobblestones are relatively well-preserved and the types are relatively rich. There are many large-scale cobblestones in the southwest. Cobblestone resources are widely distributed, with large reserves and great development value. Many places in my country have the resource conditions to use cobblestones to produce machine-made sand.
After solving the problem of raw materials, it is time to consider the equipment and processes required for production. How to "restore" cobblestones to machine-made sand better and faster?
Because the quality of pebbles is hard, compressive and wear-resistant, these characteristics determine that the process of producing machine-made sand for pebbles is not so simple. Only with diamonds can we dare to do this porcelain work, and the first consideration is processing equipment.
Generally, the pebbles seen in daily life are small in size, but the pebbles in many places are distributed in sedimentary form and have a large volume. Therefore, from a general point of view, the production process must go through three steps of coarse crushing, medium and fine crushing, and sand making. The main crushing equipment to be used in the segment process are jaw crusher, cone crusher and Sand Making Machine.
Jaw crusher for front-end crushing
The jaw crusher has a strong crushing capacity and is used in the first step of crushing, and it is also an important part of the production line to crush hard materials such as pebbles with large diameters.
Series Jaw Crusher
Bellian Group's jaw crusher has a large crushing ratio and high output, and has many unique designs. The deep V-shaped crushing cavity can allow the material to enter the crushing cavity without hindrance and improve the feeding capacity; the motor and the crusher are integrated design, the whole machine Small size, saving working space; using bolted frame to avoid the risk of stress concentration and improve the convenience of transportation.
Cone crusher for medium and fine crushing
Cone crusher can be used for further crushing of various hard materials, such as cobblestone, granite, basalt and other hard and commonly used sand making raw materials. Cone crusher has good wear resistance and ideal grain shape. Taking the commonly used hydraulic cone crusher as an example, it can be divided into two types: single-cylinder and multi-cylinder.
Single Cylinder Hydraulic Cone Crusher
Bellian Group's SC series single-cylinder hydraulic cone crusher is an ideal fine crushing equipment with the advantages of low operating cost, high performance, constant feed capacity, high throughput, high yield and long liner service life.
Multi-Cylinder Hydraulic Cone Crusher
Bellian Group's HPM multi-cylinder hydraulic cone crusher adopts the design of laminated crushing cavity, and the product has uniform particle size, cubic shape and low energy consumption.
Impact sand making machine for sand making
Impact sand making machine is a type of sand making machine that is widely used at present. The impact sand making machine adopts the crushing principle of stone-on-stone and stone-on-iron, with high production efficiency, good wear resistance of internal wearing parts, durability and low maintenance cost.
impact sand making machine
Bellian Group's impact sand making machine integrates a variety of crushing modes and is the core equipment of the sand making industry. "The production mode can make the crushing efficiency higher and the crushing ratio larger.
The above is the main crushing equipment for building a cobblestone sand production line. In addition, the production line should be equipped with vibrating screen, feeder, belt conveyor, etc., which models are configured, but also need customers to carry out according to the requirements of production capacity, site conditions, finished product particle size, etc. Reasonable configuration, generally speaking, large-scale production lines pay attention to economy, and small-scale production lines minimize production processes. Of course, the design of the cobblestone sand production line should also follow a series of specifications, involving many aspects such as site selection, building structure, water supply and drainage, etc.
It can be said that there are many factors to be considered in the construction of a cobblestone sand production line, which is relatively complex. Bellian Group has a large number of successful case experiences, and provides cobblestone sand production equipment and production line solutions for domestic and foreign users all year round, and can tailor-made exclusive production line solutions for customers , Welcome customers from all over the country to consult or visit the factory at any time!
