Machine-made sand refers to sand that is processed by a sand making machine and other auxiliary equipment. The finished product is more regular and can be processed into sand of different rules and sizes according to different technological requirements, which can better meet daily needs. Machine-made sand requires professional equipment to produce qualified and applicable sand and gravel.
Advantages of machine-made sand
1. Machine-made sand and mixed sand are mainly used for concrete with strength grade C60 and below in construction, municipal administration, transportation, and other construction projects. When meeting the corresponding technical requirements, it can also be used in concrete projects such as ports and water conservancy projects.
2. Machine-made sand should be prepared with plastic concrete. Mixed sand should be prepared with plastic, high-fluidity and pumped construction concrete.
3. Quality advantages: fixed, stable, mechanized production methods ensure the stable, adjustable and controllable quality of machine-made sand products.
4. Quality advantages: high surface energy and hydrophilicity, multiple gradations, stable particle gradation, and improved particle shape.
5. Resource advantages: Various waste resources can be used to properly sort and process tailings. Many tailings can be made into artificial sand and gravel with machine-made sand equipment, which not only solves the problem of environmental pollution, but also improves the utilization of natural resources rate, fully in line with the requirements of circular economy and scientific development concept.

1. Fast conversion of broken mode
Optimize the structure of the crushing cavity, which can realize the rapid conversion of the two crushing modes of stone-beat-stone and stone-beat-iron. "Stone-beat-Stone" adds material layer partitions to form a dense and stable stone layer. Even if it is against medium and high-hardness stones, more cubic finished materials can still be obtained, high crushing ratio.
2. Intelligently controlled thin oil lubrication
It adopts thin oil lubrication and is equipped with an air-cooled system, controlled by PLC and intelligent instruments, which can realize automatic lubrication control and the lubrication temperature can be adjusted to provide more ideal working conditions for the bearing.
3. Humanized and easy to maintain
The machine cover on the equipment can optionally be equipped with a hydraulic lifting and opening device, which is convenient for lifting, rotating and removing the feeding hopper during equipment maintenance. The equipment can also be equipped with a suspended manual or electric hoist. When the equipment is overhauled and maintained, the machine cover, feed hopper, distributor, impeller, spindle, etc. can be easily lifted and it is convenient and quick.
4. Performance improvement of key components
It can be equipped with a manual hydraulic pump to adjust the flow rate of the impeller. At the same time, with the adjustment of the height of the distribution plate, it can accurately control the ratio of the impeller to the circumferential waterfall.
Luoyang Dahua Heavy Industry has produced sand making equipment for more than decades. It is located in Luoyang, the ancient capital, in an area with low economic consumption and low labor costs. Therefore, Dahua Heavy Industries’ crushing equipment is priced at a lower price.
