Stone is a kind of common stone in life. There are many stocks in nature, which are easy to exploit. It's very suitable for making sand and stone aggregate. So the question is, what are the machines that can make sand from stone and what's the price?

The main equipment for making stone into sand is sand making machine, but for some larger materials, the sand making machine can not meet the production requirements, it needs to use other crushing machine, such as: jaw crusher, impact crusher, cone crusher, mobile crusher. Here is a brief introduction to the functions of these devices.

1. Jaw Crusher

Jaw crusher appeared earlier crushing equipment, used for crushing materials with higher hardness. The structure is simple, firm and reliable, and the cost of maintenance, production and construction is relatively small. It is widely used in metallurgy, chemical industry, building materials, electric power, and other industrial sectors.

2. Impact Crusher / Cone Crusher

The impact crusher and the cone crusher are generally used in real life to deal with the secondary processing crushing of the materials after the jaw crusher crushing. The impact crusher is mainly used for crushing soft materials (such as granite, limestone, concrete, etc.), which has simple process, low operation cost and convenient maintenance; the cone crusher is suitable for hard materials, layered crushing, high crushing ratio, high output, shaping function and slightly more expensive than the impact crusher.

3. Sand Making Machine

For some fine-grained materials directly into the sand making process, there is no need for crushing.

Granite crushing production line is one of the common production lines in gravel production. The granite crushing plant is featured by high automation, high crushing rate, energy saving, large output, uniform particle size and good particle shape, which is suitable for construction of various large and medium-sized projects such as highway and bridge. The design output of granite crushing production line is generally 50-800t / h. In order to meet different processing needs of customers, cone crusher and dust removal equipment can be equipped.

The raw material is preliminarily crushed by the jaw crusher; secondly, the coarse material produced is transported to the fine crusher by the belt conveyor for further crushing; then, the fine crushed stone enters the vibrating screen to separate three different sizes of stones and stones, and the oversized stones return to the impact crusher for further crushing.

Advantages of Granite Process Line

The production cost of the whole production line is low. Generally, the traditional granite crushing production line needs a large amount of water for sand washing in the production. To a certain extent, the user increases the investment in water resources, while the production line does not need the investment in water, which reduces the investment in capital to a certain extent. In addition, the production line has stable operation, high production efficiency, short recovery cycle and small investment risk, which is worth the investment of users and friends.

1. The layout design of the production line is reasonable, the floor area is small and the running stability is good;

2. The overall investment is small, the income is high and the operation cost is relatively low;

3. Simple operation and high safety;

4. Simple maintenance, low cost and strong expansibility in the later stage.

With the rapid development of urbanization, a large number of construction wastes come into being. Construction wastes include waste brick, concrete, rock, waste iron wire, rebars and so on and these materials can be recycled completely after processing. Portable crusher plant is especially suitable for crushing rock and construction waste and it greatly expands the concept field of coarse crushing and fine crushing of rocks and construction waste. Its design principle is to eliminate these crushing barriers brought by crushing site, environment and complex logistics standing in the customers’ position. Therefore, reasonably dealing with the construction waste has attracted people’s attention increasingly.

The disposal of construction waste in China is relatively late, but it is urgent to handle these construction wastes. Now lots of building solid wastes are produced because of the demolition of city and the rural urbanization. The stacking and landfill of these wastes not only occupy the land, but cause serious pollution to groundwater and air with waste gas and water generated by fermentation and washing under the effect of temperature and moisture.

The processing and recycling of construction waste is a systematic engineering, we should pay more attention to improve the level of technology processing of construction waste. Most of the construction waste can be recycled as renewable resources, such as using portable crushing plant to crush the abandoned building concrete and waste bricks in one-time. The coarse and fine aggregates can be used as in the productions of concrete, slurry and other building materials, such as bricklaying, wallboard, floor tile and so on. The coarse and fine aggregates can also be used as the materials of highway pavement base after mixing with curing materials. When the waste brick and tile (a kind of burnt clay material) crushed into powder material, it has pozzolanic activity and can be used as concrete admixture replacing coal ash, slag powders, mountain flour and so on. The portable crushing station is specially designed for construction waste in recent years; it can crush the construction waste which can be manufactured into construction materials by sand maker and the final products are environmentally friendly.

Raymond mill can also be called Raymond grinding mill. Due to its stable performance, strong adaptability and high cost performance, it has been widely used for processing non-metallic minerals since it was introduced to our country. To ensure the normal operation of Raymond mill, it is necessary to formulate maintenance and safe operation rule, and at the same time, the customers need to learn the general knowledge on the maintenance of Raymond mill for a rainy day.

1. In the running process of Raymond mill, there should be fixed personnel watching it and the operators should have certain technical level. Before the installation of the milling equipment, the operators should be given necessary technical training to learn the principle and performance of Raymond mill and know the operation procedure.

2. To ensure the normal work of the grinding mill, it is necessary to formulate maintenance and safe operation rule, and there should be necessary examination and repair tools and lubricating grease and relevant accessories.

3. After being used for a period of time, the workers should examine and repair the equipment, and repair or change the quick-wear parts such as grinding roll, grinding ring and scraper knife. Before and after the use of the grinding roll, carefully check the connecting bolts and nuts to see whether they are loose and whether the lubricating grease is sufficient.

4. When changing new grinding roll after it is used for about 500 hours, clean all the antifriction bearings inside the roller shell, and timely change the damaged parts, and the refueling tool can choose manual petrol pump and grease gun.

5. The adjustment of the fineness. As the materials have different size, hardness, water content and proportion, the processing fineness will be different. The workers can process the upper analyzer, choose high rotating speed for high fineness and low rotating speed for low fineness.

6. As for scrap limit of grinding roll and grinding ring, the rest minimum wall thickness should never be thinner than 10mm.

7. When Raymond mill is stopped, first stopping feeding, and the main engine will continue to run to grind the rest materials inside the grinding chamber, in about one minute, turn off the main motor and the motor of the analyzer to stop the grinding work, and then turn off the motor of the blower to clean the residual powers.
