Regarding sand making equipment, there are many types to choose from, such as hammer crusher, composite crusher, and vertical shaft impact crusher, which makes us dazzled when choosing equipment. Many friends leave messages asking which is better. Simple (no need to increase storage and feeding equipment), can you use a hammer to break sand? Affected by the process and cost, many small production lines in the past would consider using hammer crushing to make sand. After communicating with many sand and gravel owners, the reasons why it is not recommended to use a hammer to break the sand and gravel production line are mainly the following two aspects:
1. The grain shape of the material is not good (1,2 gravel is ok)
Although the process of sand making by hammer crushing is simple, the yield is low, it is easy to be crushed, and there are many powdery materials. In addition, the finished aggregate will have micro-cracks and low compressive strength, which will affect the quality of the aggregate and also affect the sales. Hammer crushing is mainly used for crushing.
Among the main sand making equipment on the market at present, the vertical shaft impact crusher has the best particle shape after shaping, and can be used to produce Class I sand. Friends who have high requirements for grain shape can consider adding a shaping machine.
2. Serious loss
Hammer crushing is suitable for processing medium and soft ores, such as limestone, coal gangue, dolomite, shale, etc. It cannot handle materials with high hardness, otherwise the hammer head wears quickly, the replacement frequency is high, and the increase in cost also delays production.
A friend said that he uses a hammer to break granite, and the hammer head needs to be replaced every 2 or 3 days. The hammer head alone costs thousands of dollars. Another friend broke quartz sand. It is not good and the loss is serious, so I have to reconsider changing the impact breaker.
It can be seen that hammer sand making is not the first choice in our sand production line, but the specific situation should be determined according to the actual situation. If you have doubts about sand making, you can learn more about it.
