The sand-making building, also known as the tower-type sand-making system, adopts the dry-type sand-making mode. It places sand-making, screening, powder selection and other equipment in a three-dimensional space. It integrates sand-making, shaping, stone powder control, grading adjustment, and moisture content control. It is an advanced energy-saving and environmentally friendly sand-making system. The processed mechanical sand is widely used in construction, bridges, railways and other industries. How much is a set of sand-making buildings?What are the advantages and disadvantages?This article is introduced in detail, with technical parameters attached
Advantages of sand building
1. It covers a small area and is not subject to environmental restrictions.
Intensive tower design, small footprint; traditional wet production lines are limited by water sources and the environment, and sand must be made and washed in places with rich water resources. The sand-making building adopts a dry sand-making model, which is not restricted by the environment and can also save water resources.
2. The quality of the mechanism sand is high, and the gradation control is more refined.
The HVI sand making machine equipped with the dry sand building system has the dual functions of sand making and shaping, which makes the finished mechanism sand have better grain shape and adopts air sieve, which is more accurate than wet sand. The grading is more accurate, the powder content is freely adjusted between 3-15%, and the moisture content is also easy to control.
3. Intelligent production, safe and fast
Supporting an intelligent control system, it can start/stop with one key, monitor the operating status of each host in real time, and ensure the continuous and stable production of the system.
4. No noise and no dust, high environmental protection standards
Fully enclosed structure, higher standards of environmental protection facilities, falling by gravity, no belt conveyor, less dust, bag-type dust collector, offline cleaning pulse dust removal, dust removal efficiency as high as 99%; polyester peritoneal filter bag has excellent filtration performance, and the soot emission concentration is ≤20mg/m3
Process flow
After the raw materials are crushed by the sand making machine, under the action of the mold control screen and the dust removal module, they are divided into three ways: stone powder, rework and quasi-finished sand.After the stone powder passes through the dust removal module, it is uniformly stored in the powder silo, and the quasi-finished sand becomes the finished product after humidification and stirring.The rework needs to be processed by an impact sand-making and shaping machine, and then sieved and dusted until it becomes finished sand or stone powder.
