Nowadays, garbage is regarded as the most potential and inexhaustible "urban mineral" and "misplaced resource". This is not only the deepening and deepening of the understanding of garbage, but also the inevitable requirement of urban development. The emergence of portable crusher plant to deal with construction waste has become the overlord of the industry.

A professional construction waste recycling and treatment equipment - portable crusher plant. After being crushed by the portable crusher plant, the construction waste can be used as raw materials for building materials production, and made into various standard brand-new building materials products such as concrete bricks and blocks through various building materials production lines. This not only makes the resources recycled for many times, energy conservation and environmental protection, but also has low cost and very high economic and social benefits.

Construction waste is mostly solid waste, which is generally generated in the process of construction or the maintenance and demolition of old buildings. Although the contents of various components of garbage produced by buildings of different structural types are different, its basic composition is consistent, mainly composed of soil, residue, scattered mortar and concrete, masonry and concrete fragments produced by chiseling, reinforced concrete pile head cut by piling, metal, bamboo wood, waste from decoration, various packaging materials and other wastes, Among them, coarse and fine aggregates are produced from waste building concrete and waste masonry, which can be used to produce concrete and mortar with corresponding strength grade or to prepare building materials products such as blocks, wall panels and floor tiles; Using waste bricks and tiles to produce aggregate can be used to produce recycled bricks, blocks, wall panels, floor tiles and other building materials products. It has the advantages of reducing construction waste, recycling, saving natural resources and protecting ecological environment, and has high economic value.

Both artificial sand and natural river sand belong to construction sand. The difference is that artificial sand is processed by sand making machine, which is a kind of artificial sand; River sand is formed naturally and can be mined and used directly. And they are very different in materials, resources, environmental protection and production costs.

Material Aspect

Artificial sand: it is processed by sand making machine and other sand making machine. Now, sand making machine technology has made great progress, which can meet the needs of large-scale production and construction requirements of users.

Natural sand: it is formed after long-term seawater impact. Natural sand can be used as construction sand, but its resources have been exhausted and scarce, so it is urgent to replace it. In this respect, artificial sand is better than natural sand.

Resources

Artificial sand: there are many kinds of sand and stone raw materials and rich resources, so there is no need to worry that there are no raw materials in the use process, and there are a variety of sand making machine to choose from.

Natural sand: This is a kind of natural resource, which needs long-term seawater impact to form. The formation period is long. And now the natural sand has gradually dried up, unable to meet the market demand.

Environmental Protection

Artificial sand: it can meet the production needs of different users by adjusting the particle size of materials produced by sand making machine. It has the function of environmental protection.

Natural sand: mining is usually carried out in river channels. However, the large-scale exploitation of natural sand will cause some damage to the ecological environment such as river and beach.

Production Cost

Artificial sand: to be processed by various sand making machine. In the process of sand making, we need to buy sand making machine, but the purchase of equipment is a once and for all transaction.

Natural sand: it is a natural resource. It can be directly used for production after mining, which can reduce the production cost. However, due to the reduction of resources, the mining cost is relatively high.

Sand making plant has been in full swing in the industry laying and operation. In the face of different hardness of stone, different processing environment, different discharge requirements and so on, the various sand making manufacturers are also actively responding. However, now we pay more attention to the cost of stone production line.

Since most people care about the price. Today's brief introduction to the sand making plant cost.

A complete artificial sand making process usually consists of the following equipment: vibrating feeder, jaw crusher, impact crusher, cone crusher, sand making machine, vibrating screen, conveyor, etc.

The cost of production line can be roughly divided into two parts. One is the cost of investment, that is, the cost of purchasing equipment. The cost of equipment is determined by the hardness of stone, the size of feed, the fineness of discharge and the shape of particles; the other is the cost of production, that is, the operation cost, according to the total power of the equipment and the replacement cycle of vulnerable parts.

Different users have different ideas and expectations. Generally speaking, new users of mining machinery industry, due to their lack of funds, lack of experience and other related factors, often choose more economical equipment, that is, to make the production line equipment cheaper. Even if the operation cost is higher and the output is lower, it is acceptable. After a period of development, if the capital is strong, the new equipment will be replaced Considering the cost of operation; users of large mines are different. They mainly make decisions according to the requirements of production and operation cost, rather than paying special attention to the price of equipment itself.

How to save the cost of sand production line?

Reasonable selection of high-quality mining machinery and equipment, more than for mining machinery manufacturers, select the right manufacturer is very important, this is related to a series of after-sales problems, such as inevitable maintenance, repair and replacement of parts and components; price is very important, as the saying goes, a price points a goods, in the current network development, the price of crusher products has already It's very transparent. If suddenly, the price of one company is very low, and there is a big difference between the prices of other manufacturers, you should be very careful. Generally speaking, there are two situations: one is the refurbished machine, that is, the second mobile phone. There is another possibility that the machine is not the right type. In order to get a share of the market environment, many manufacturers specially use small-sized accessories to place on the larger machines. On the surface, they are consistent, but the weight is quite different. In addition, the actual output is not up to date. Therefore, users should keep their eyes open when selecting equipment.

Stone production line is a special production line for sand and stone used in construction, highway, railway and other industries. The main equipment of the Complete Stone Crushing Plant includes jaw crusher, impact crusher, hammer crusher, fine crusher, sand making machine, etc. Stone production line is generally suitable for limestone, pebble, quartz sand and other materials. Among them, the river pebble is a kind of material with high hardness. In addition to routine maintenance and repair, special attention should be paid to some other problems when using crusher to crush and make sand.

The maintenance of jaw crusher generally includes lubrication and maintenance. Frequent attention and timely lubrication of friction surface can ensure the normal operation and service life of the machine. Jaw crusher in the maintenance of regular inspection, replacement of parts, regular maintenance, equipment maintenance records. When crushing hard materials, the wear of the equipment is more obvious. Therefore, for the frequently worn parts (jaw plate, elbow plate, etc.) of jaw crusher, it is necessary to establish a detailed service life test, so as to know the operation limit of the equipment.

The jaw crusher can start the crusher after confirming that there is no material in the crushing chamber. The starting sequence of the whole sand making production line is dust collector (optional), discharge conveyor, jaw crusher, feed conveyor, vibration feeder, etc. In order to prevent steel articles or parts from falling into the crushing chamber, if possible, a detection iron removal device can be installed behind the vibrating feeder. Adjust the feeding amount of the feeder, increase gradually from small to large. Generally, the height of the material in the crushing chamber should be controlled to be four fifths of the height of the crushing chamber. It should also be noted that the feed particle size should not exceed four fifths of the width of the feed port. The jaw crusher can normally play its appropriate efficiency if the feeding granularity is continuous and uniform.

Maintenance of stone crusher machine in gravel production line:

1. Large feeding port, high crushing chamber, high hardness, large block and less stone powder.

In the mining industry friends, the stone crusher machine must not be unfamiliar, the following to talk about the stone crusher related to a few basic concepts.

1、 Comminution

Under the action of external force, the solid material overcomes the cohesion and makes the solid material broken, which is called comminution. The external force can be applied by human, mechanical, electric or blasting methods. Most of the quarrying methods are blasting, while the mechanical method is used to break the large block materials into small ones.

With the grinding process, the total surface area of the material is constantly increasing. Therefore, after the solid material is broken into small pieces or fine powder, the reaction speed of physical and chemical action can be increased. In addition, the mixture of several different solid materials must be in the fine powder state to obtain uniform effect.

2、 Fragility of materials

The difficulty of crushing materials is called fragility. When the same crusher grinds different materials under the same operating conditions, the production capacity is different, which indicates that the fragility of various materials is different. Density, structural uniformity, moisture content, viscosity, crack and fragility are related to the strength and hardness of the material, indicating the material's resistance to external forces, surface condition and shape.

The materials with high hardness and low strength are easier to be broken than those with high strength and low hardness. Obviously, the material with high hardness is not necessarily difficult to crush, but it is difficult to grind, and at the same time, the working surface of grinding machine is easy to wear.

3、 Crushing system

The crushing operation can be completed by different crushing systems. There may be different crushing systems depending on the nature of the material being crushed, the size of the draw, the required crushing ratio, the scale of production and the crusher used.

The crushing system includes two aspects: crushing stage and process in each stage. The number of stages of crushing system mainly depends on the crushing ratio and the type of crusher. In order to meet the requirements of increasing crushing ratio and reducing crushing stages, the crusher will develop to large crushing ratio, high efficiency and large scale.

Due to the continuous improvement and development of crusher, the improvement and development of crushing system has good conditions. At present, the crushing system not only reduces the number of crushing stages and simplifies the production process, but also carries out crushing and drying in a single process at the same time.

Manufactured sand is the main raw materials for infrastructure, concrete and mortar. At present, there are two types of natural sand and manufactured sand in China. Natural sand with particle size less than 5mm is crushed and screened into stone particles with particle size less than 4.75mm. According to the size of sand, they are coarse sand, medium sand and fine sand respectively, and coarse sand with particle size above 0.55mm is coarse sand, Medium sand is less than 0.5mm and more than 0.35mm, fine sand is between 0.35-0.25mm, and ultra-fine sand is less than 0.25mm.

Artificial sand making process is a kind of industry with small investment and quick effect. In addition, with the acceleration of mechanization in recent years, the sand and stone processing machine has greatly reduced human and material resources, and has low energy consumption, which can easily realize mass production. Bridges and real estate are in a large number of construction, and gravel aggregate is the raw material The demand for aggregate and building aggregate continues to increase, and the production of aggregate and building aggregate equipment is a complete set of artificial sand production line equipment.
