Summary：The requirements for environment are becoming more and more stringent. So it is important for aggregates industry to choose a right sand making machine which can meet the environmental requirements. So which kind of sand maker can we choose? Let's introduce it in details.
The prices of aggregates are restricted not only by natural mining, but also by the environmental requirements. At present, environmental protection is the focus of global development. The requirements for environment are becoming more and more stringent. So it is important for aggregates industry to choose a right sand making machine which can meet the environmental requirements. So which kind of sand maker can we choose? Let's introduce it in details.
Features of environmental sand making machine
How to identify a sand machine is green? Here is a summary of the environmental sand making machine several characteristics:
Whether it has dust control system or not?
Whether the sand making machine is equipped with a dust control filtration system is an important reflection of whether the sand making machine is environmentally friendly. The dust control system can make the dust produced by the material circulating in the vortex cavity. Dust is isolated in the sand making equipment, which greatly avoids the dust overflow and pollution.
Whether it equipped conveyor belt spray device or not?
As we all know, generally, there is a spray device which is set around the conveyor belt at the connection of the sand making machine. It can help to reduce the dust and its concentration in the transportation by spraying water mist. This can greatly reduce the dust pollution.
Whether it equipped the noise reduction device or not?
It is inevitable for sand machine equipment to produce noise in the operation process. Greenly Sand making machine is made of eco-friendly materials like high chromium steel, which can enhance wear resistance and sound insulation effect, if it is coupled with noise reduction device, the machine can also effectively reduce noise pollution.
Common types of eco-friendly sand making machine
The common environment-friendly sand making equipment includes impact sand making machines, composite sand making machines and mobile sand making machines. Here are three common sand making machines:
1.Impact sand making machines
As the latest type of sand making machine in the market, it can handle both ore materials with high hardness (like pebbles, granite) and low hardness (like bluestone, gypsum). The function of impact sand making machine can be adjusted according to the nature of the material. In addition, the impact san making machine adopts "Rock On Rock" and "Rock On Iron" crushing mode, and adopts reliable thin oil lubrication, which make it has advantages like high efficiency, low energy consumption (reduce by at least 30% at the same charge).
2. Composite sand making machines
This kind of sand making machine is suitable for materials with high water content. It has fine and coarse grinding functions with table performance. When it’s working, its noise is less than 75 decibel. The manufactured sand produced by the compound sand making machine is cubic, which has high accumulation density, long service life and great economic benefit.
3. Mobile sand making machine
The mobile sand making machine is of high degree of intelligence. A sand making machine can be used as a mobile sand making machine by matching it with a tyre or crawler frame. To sum up, the mobile sand making machine has advantages of reliable production, convenient transfer, and intelligent operation, energy-saving and environmental protection.
The above is the introduction of eco-friendly sand making equipment and three common environmental sand makers. It is very important to choose eco-friendly sand making equipment if the aggregates industry wants to get long term growth.
