Summary:artificial sand making is not affected by climate and season, it can be effectively controlled in the production process and will not be subject to objective environmental conditions

With the decrease of natural sand, the artificial sand market has shown great potential and vitality. Especially in recent years, there is a huge demand in the construction market. Because the production of artificial sand is not affected by climate and season, it can be effectively controlled in the production process and will not be subject to objective environmental conditions, which is conducive to large-scale production and promotes the rapid development of the sand and gravel market. So how to configure the artificial sand making plant?

The sand making plant mainly uses a series of stone crushing equipment to crush the stone and produce artificial sand and stone such as sand and aggregate. The equipment configuration of different production lines is different, and two basic criteria shall be followed during configuration:

1. Understand material characteristics and requirements

Before configuring the aggregate production line, it is necessary to find out the properties of the materials to be processed, such as hardness, size, etc. Consider what kind of crusher and sand making machine to configure according to the broken materials, output requirements and particle size requirements of finished products. The selection of crushing and sand making equipment should not only meet the output, but also consider the size of the feed inlet to avoid the inability of materials to enter.

2. Understand your economic strength

The economic foundation determines the superstructure. When configuring sand and gravel production lines, we should choose different production lines according to our own investment strength. Don't buy blindly. What suits you is the best. Users should configure it according to their actual purchasing power.

Cost budget of artificial sand making plant:

  • 1. The purchase cost of raw materials is different. The ore prices in different regions are different. If there are their own mines, they do not need to be considered;
  • 2. Infrastructure construction cost, including standardized plant, closed storage warehouse, comprehensive environmental protection facilities, roads in the plant, water supply and drainage, power supply and distribution, office and living facilities, etc;
  • 3. The cost of complete equipment, including the cost of feeding, crushing, screening, sand making and other complete equipment;
  • 4. The operation cost of the production line, including workers' wages, utilities, maintenance expenses of vulnerable parts, etc.

The investment cost budget of sand production line varies greatly according to different raw materials and production scale.

How to configure an artificial sand making plant?

The equipment configuration of artificial sand making plant includes vibrating feeder, coarse crusher, medium and fine crusher, vibrating screen, sand making machine, belt conveyor. Among them, feeders, vibrating screens and conveyors are auxiliary equipment.

artificial sand making process

1. Feed

The stones blasted from the mountain are sent to the vibrating feeder through the dump truck. Vibrating feeder has strong adaptability, stable operation and high cost performance. It is a feeding equipment widely used in sand and gravel enterprises. The vibrating feeder can feed the crushing equipment continuously and evenly, effectively prolonging the service life of the equipment. Small volume, light weight, small power, compact structure, convenient installation, low operation cost and low investment cost.

2. Coarse and Fine Crushing

According to different crushing purposes, crushers are divided into coarse crushing and medium fine crushing: coarse crushers can process large stones to medium particle size at one time; The medium and fine crusher is mainly used to further crush and reshape the coarse crushed stone to meet the high standard requirements of construction projects for stone. The vibrating feeder evenly sends the stones to the jaw crusher, and the broken stones from the jaw are broken for the first crushing, that is, coarse crushing. The stones broken from the jaw are then transported to the cone crusher or impact crusher through the belt conveyor for secondary crushing, that is, fine crushing.

3. Sand Making and Screening

The finely crushed materials are sent to the sand making machine by belt conveyor for fine crushing, and the finely crushed materials are screened out by vibrating screen.

The general production line can be completed by the above three steps, but for those with strict requirements on the powder content of sand, a sand washer can be added after fine crushing and screening. Circular vibrating screen and linear vibrating screen are common in sand production line. Belt conveyor is the hub of sand production line. It has the advantages of low kinetic energy consumption, high production efficiency, large conveying capacity, flexible use, economy and practicality.

Configuration of sand production line with different materials

1. Pebble sand production line

Pebble features:

Pebbles are mainly composed of silica, which has the advantages of non-toxic, tasteless, strong corrosion resistance, hard quality and strong pressure resistance. They are not only the main material for the production of artificial sand and gravel, but also a kind of green building material.

Pebble sand production line configuration:

The equipment configuration of a cobble sand production line with an hourly output of 50-70 tons is: feeder + 2 sets of fine jaw crushers + sand making machine + vibrating screen + sand washing machine + fine sand recycling machine + belt conveyor

2. Granite sand production line

Granite features:

Granite has hard texture, high strength, wear resistance and weathering resistance. It has the title of "king of rock". It is a good building material. Granite is rich in resources with low mining cost but high product value.

Granite sand production line configuration:

The equipment configuration of a granite sand making production line with an hourly output of 80-130 tons is: feeder +  jaw crushers + vibrating screen + conical crusher + sand making machine + fine sand recycling machine + belt conveyor

3. Quartzite sand production line

Quartzite characteristics:

Quartzite is mainly composed of silica. It is hard, wear-resistant and chemically stable. It is an important industrial mineral raw material. Quartzite is widely used in glass, building materials and other industries after crushing and sand making. It is mainly processed and utilized by quartz production line.

Quartzite sand production line configuration:

The equipment configuration of a quartzite sand production line with an hourly output of 30-45 tons is: vibrating feeder + 2 sets of fine jaw crushers + sand making machine + vibrating screen + sand washing machine + fine sand recycling machine + belt conveyor

4. Sandstone sand production line

andstone characteristics:

Sandstone is a kind of sedimentary rock, most of which is composed of quartz or feldspar. Sandstone is a widely used building stone.

Sandstone sand production line configuration:

The equipment configuration of a sandstone sand making production line with an hourly output of 60-80 tons is: silo + vibrating feeder + jaw crusher + impact crusher + sand making machine + vibrating screen + sand washing machine + fine sand recycling machine + belt conveyor

5. Limestone sand production line

Limestone characteristics:

Limestone is mainly composed of calcium carbonate, which belongs to medium and low hardness. It is often used as building materials and industrial raw materials. Limestone sand production line is also very common.
