[Focus on the Two Sessions] The sand and gravel manufacturing industry is sailing at the right time-"China cannot lack manufacturing at any time"

On March 5, 2023, the 14th People's Congress successfully opened in the Great Hall of the People in Beijing.

Market demand analysis of China's sand and gravel industry Development trend forecast of China's sand and gravel industry

China's sand and gravel industry presents environmental protection, large-scale, intelligent and other development trends, the demand for high-quality development of sand and gravel production equipment environmental protection, energy saving,..., large production capacity, particle grading and other aspects of higher requirements.

Demand drives cement, sand and gravel prices back up! Sand and gravel industry to good development

Recently, with the domestic economic recovery and the construction of major projects, demand-driven prices have rebounded, and the prices of basic building materials such as cement, sand and concrete have risen sharply. As far as Guangdong is concerned, since February, cement has continuously increased by 80 yuan/ton, sand and gravel has increased by 25 yuan/ton, and many concrete companies have also notified to increase concrete prices by 50 yuan/square.

Henan sand aggregate vibrating screen manufacturers talk about the working principle of the motor

The motor drives the vibration exciter to produce vibration. When the whole equipment is upward, the spring recovers and stretches. The material on the screen is thrown up and becomes loose. When the whole equipment is downward, the spring is compressed and the material falls down to the screen again. The equipment vibrates up and down continuously. The material is thrown up and down for many times. The material smaller than the size of the screen is separated. The material larger than the size of the screen is discharged from the end, this achieves the purpose of coarse and fine aggregate screening. Performance characteristics:

Sand and gravel aggregate vibrating screen manufacturers say what is fine aggregate

Sand aggregate vibrating screen manufacturers say, aggregate is concrete in the skeleton and supporting role or filling the role of granular loose material. Aggregate is divided into coarse aggregate and fine aggregate. Coarse aggregate includes pebbles, crushed stone, waste slag, etc., and fine aggregate is mainly medium and fine sand. When mixing concrete, the cement is mixed into a thin paste by water. If no aggregate is added, it will not be able to form and will lead to unusable. So aggregate is a very important raw material in construction.

Green machinery to share the little knowledge of sand and gravel aggregate production line

Green machinery to share the sand aggregate production line small knowledge. Aggregate production line is a kind of mechanical equipment for producing sand and gravel aggregate. It is composed of vibration feeder, jaw crusher, impact crusher, vibrating screen, conveyor belt and other equipment. Different equipment combinations can be selected according to different production requirements. Its main function is to process ore, stone and other raw materials into standard sand and gravel aggregates through crushing, screening and other processes, which are used in construction, highway, railway, water conservancy and other fields of construction projects.
