Sand making machine

We all know that in the production of sand and gravel, the impact crusher can be used in the medium and fine crushing stage, and the sand making stage uses a sand making machine, but in fact, the function of the impact crusher is not limited to medium and fine crushing production.

Here is to introduce whether the impact crusher can make sand, and what are the advantages and disadvantages of impact crushing and sand making.

Can the impact crusher make sand?

First of all, the impact crusher can be used to make sand, because the hammer-type sand making method adopted by the machine makes the finished sand particles better, mostly cubic, and less powder. Generally speaking, the size of sand and gravel produced by the impact crusher is about 3-5mm, which can meet the quality standards of construction sand. Therefore, the impact crusher can be used for sand making, but its sand making effect and scope of application are limited.

What is the principle of the impact crusher to make sand?

The impact crusher is a device that uses impact energy to crush materials. When the material enters the plate hammer action area, it is thrown to the counterattack device by the high-speed impact of the plate hammer, and then bounces back from the counterattack liner to the plate hammer action area and is counterattacked again. The material is repeatedly crushed from large to small in the crushing chamber until it reaches the required particle size and is discharged.

Of course, the impact crusher has advantages and disadvantages in sand production. Let’s analyze it in detail below:

Advantages of impact crusher sand making

The advantages of impact crusher sand making are mainly: the finished product of impact crusher has good particle shape, and the machine has its own screening system. The processed materials are screened during production, which can reduce the powder content in the finished product.

In addition, the impact crusher has a large adjustment range for the discharge port, so it can meet the needs of different industries for sand and gravel products. The intelligent control system is equipped with a control panel, which makes the maintenance of the machine quick and convenient;

The impact crusher contains grate bars, which can perform preliminary screening of the material, and has its own screening function, which can reduce the powder content.

Wide range of application: The impact crusher can be used for sand making of medium hardness materials, such as limestone, dolomite and other ores.

Disadvantages of impact crusher sand making

The main disadvantages of impact crusher sand making are: We know that the main function of impact crusher is crushing, and it is not a professional sand making equipment, so it has certain disadvantages in sand making production, which are mainly manifested in the following aspects:

1. Impact crusher is mainly suitable for processing soft materials. When crushing materials with higher hardness, the service life of the internal hammer will be relatively shortened. Therefore, in the demand for sand making production, impact crusher is dedicated to crushing and making sand of softer materials;

2. There are restrictions on material hardness: When processing harder materials, the service life of internal hammers and other components will be shortened.

Non-professional sand making equipment: Compared with professional sand making equipment such as vertical shaft impact crusher, it is slightly inferior in sand making efficiency and finished product quality.

How to choose a suitable sand making machine?

In some sand and gravel aggregate production lines, impact crushers are often used in the medium and fine crushing links to provide materials with suitable particle size for subsequent sand making processes. For example, in the limestone crushing and sand making production line in Guizhou, China, the PFW impact crusher and the VSI sand making machine work together. The impact crusher first performs medium and fine crushing, and then the sand making machine performs shaping and further sand making.

For materials with higher hardness, the equipment that can be selected for sand making includes hammer crusher, impact crusher, etc. These equipment also have their own advantages and disadvantages in sand making production. When we choose these different equipment, in addition to combining production needs, we also need to pay attention to cost constraints. Because different types of equipment have different performances, the quotations are different.

As far as the quotation of impact crusher is concerned, different models of impact crusher have different functions, which is mainly reflected in the different sizes of materials that can be processed, different production capacity, different finished product sizes, etc., so the quotations are different. In addition, factors such as the impact crusher manufacturer and market conditions will also affect its selection factors. So when we choose, we should compare three companies, not only for the performance of the equipment, but also for the price, and combine various factors to choose a more cost-effective impact crusher.
