What equipment is used to produce sand for construction? sand making equipment price
High-quality sand and gravel aggregate is an important raw material in the construction industry. Moreover, natural sand and gravel mining is limited, and machine-made sand and gravel have become the new favorite of the market, and the market space is very large. Therefore, sand and gravel plants are hot projects in various regions; So, what equipment is needed to produce sand for construction? Let's mainly explain the production knowledge of machine-made sand for construction:
Machine-made sand is made by excavating, crushing and screening rocks. Now it is mainly produced by dry powder method. Due to the different rock types, crushing methods and sorting processes used in the production of machine-made sand, the quality of machine-made sand varies greatly. The stone powder content varies. Compared with natural sand, artificial sand has greater advantages. The production of artificial sand is completely in accordance with the national construction sand standards. It is a high-standard artificial sand executed according to the new standard GB/T14684-2011 "Sand for Construction".
Generally, a complete machine-made sand production line needs: vibrating feeder + conveyor + stone screening equipment + crusher + sand making machine + sand washing machine + control system and other equipment; the following types are mainly used in the production process equipment:
1. Coarse crushing equipment - jaw crusher
Jaw crusher is the earliest solid and durable crusher equipment on the market. It is used for coarse crushing of construction sand raw materials. It is an ideal choice for coarse crushing of various ores. The advantages of this equipment are as follows:
01. Wide application fields: It can crush any material with a compressive strength less than 320 MPa without being affected by factors such as ore hardness and humidity, with good flexibility.
02.Intelligence: Adopting new analysis technology, the crushing strength of the material is higher, the crushing ratio is larger, and the output is higher.
03. Easy to operate: Bearings and other devices are made of unique wear-resistant materials, with more stable operation, high productivity, low vibration rate and low maintenance cost.
2. Secondary crushing equipment - impact crusher
The impact crusher is used for the secondary crushing of ore. It is a high-capacity and energy-saving stone crusher equipment with simple structure design and reliable performance advantages.
01. The wearing parts such as the lining plate of the impact crusher have good wear resistance, stronger toughness, less failure rate, and greatly extended service life.
02. Small footprint, very light weight, easy operation and maintenance.
03. The parts of the crusher are easy to disassemble and install, the operation is safer and more stable, and the production efficiency is relatively high.
3. Fine crushing equipment - sand making equipment
Sand making machine is a common equipment for ore sand making and shaping. It has great advantages in sand making type, output, quality, usability, etc, mainly reflected in the following aspects:
01. The particle size of the sand and gravel materials produced by the SMMVIK sand making machine is more uniform, the content of cubes is high, there is no material clogging problem during the operation, and the operation is stable.
02. Standard self-lifting arm, which is coaxial with the lifting arm, which is convenient for the maintenance of the impeller and bearing cylinder; the hydraulic jack is used to lift the feeding hopper, which is easy to maintain; the height of the guardrail is lowered to avoid interference when the feeding hopper is unscrewed.
03. It is lubricated with thin oil and equipped with an air cooling system. It is controlled by PLC and intelligent instrument, which can realize automatic lubrication control, and the lubrication temperature can be adjusted to provide more ideal working conditions for bearing work.
4. Cleaning equipment - sand washing machine
The construction field has very high requirements on the purity and grade of sand and gravel, so it is necessary to clean the crushed sand and gravel during the processing process, which requires the use of sand washing machine equipment, which can improve the recycling rate of sand and gravel. Play a very important role, the advantages are as follows:
01. The cleaning efficiency is high, the bearing capacity is strong, the processing capacity of sand and gravel per unit time is large, and the output is very high.
02. It can be produced in the open air, has strong adaptability to the environment, and has very good wear resistance and corrosion resistance.
03. There is basically no dust during operation, and the noise is also ultra-low, which meets the national environmental protection standards.
SMMVIK has more than 25 years of experience in the production of mining crushing machinery and equipment, and the machine-made sand production lines configured for customers are located in nearly 170 countries and regions at home and abroad; the company's technical personnel will also be based on the user's production requirements and characteristics of sand and gravel. Configure reasonable production line equipment, design scientific production line process, and promote the sustainable development of sand and gravel.
