Features
- It adopts material storage and distribution system to manage material storage and distribution so as to ensure accurate feed and precise dispensing for even density and high compactness of products.
- It utilizes frequency conversion synchronous vibration mode and the vibration frequency can be adjusted according to different production requirements to attain low-frequency feeding and high-frequency molding. The change of amplitude and vibration frequency in the process of frequency conversion is beneficial for concrete compactness.
- In a variety of data control systems for the production, it is easy and simple to operate and adjust the material changes to produce various products.
- The automatic diagnosis system has alarming function, which can help timely troubleshooting. The remote data monitoring and recovery, system upgrading and fault diagnosis functions can be realized through network connection
Widely Used Raw Materials
The materials choosing are a wide range, such as slag, fly ash, building rubbish, coal gangue, cement, sand, and so on. You just need the correct ratio of materials. Then the concrete block can be of high quality. For example, fly ash block ratio:
Normally: fly ash 50%、gravel 35%、cement 8% and sand 7%
Or fly ash 50%、gravel 42%、cement 8
