With the shortage of sand and stone, many enterprises make a lot of money. The waste rock debris left in the sand and stone mining has become an important raw material to break the sand shortage. What is debris? How to process waste rock into machine-made sand, and what else is the use of waste rock?

 

What is waste rock?

River pebble, granite, sandstone and limestone are common materials for sand making, which will produce more waste rock chips in the process of production and processing. The size of these debris is different, the content of 2.36-4.75mm and below 0.15mm is higher, while the content of 0.3-1.18mm is less. The stacking of waste rock chips affects the environment and takes up land resources. Processing waste rock chips for pulverizing can not only realize 100% utilization of resources, but also solve the problem of "sand shortage".

 

Existing problems in utilization of waste rock chips

Since the waste rock chips have such a large application market, why don't sand manufacturers directly use these waste rock chips to form an integrated production line mode? The main reason is that it is difficult to use the waste because of its characteristics.

1.At present, the waste rock debris is mainly used as concrete. We do not have a good grasp of the influence of the quality of waste rock debris on concrete.

2.There is a lot of mud in the waste rock chips, so it is difficult to remove mud, and the cost is large. Increasing the amount of cement has poor market acceptance.

3.Different types of waste rock chips need targeted deep processing technology, and some enterprises do not have a good understanding of it. As a result, the expected economic and environmental benefits are not realized, and the enterprises have no confidence to continue to do so.

 

What kind of mill can be used to process waste rock chips?

The physical properties of waste rock chips are different with different rocks and different milling processes. The waste rock debris left by limestone mining is processed into limestone powder with higher added value, while the granite and sandstone waste rock debris is processed into concrete or aggregate.

 

The grinding equipment used in the process of processing will also be different. HCM suggests that HLM series vertical roller mill be used to process waste rock into powder. HLM vertical mill has the advantages of low energy consumption, low cost, high output and high performance price ratio, which is suitable for limestone, slag powder, calcite and other materials. The material can accept 15% moisture in the feed, which is very suitable for processing the waste rock chips with uneven surface, edges and sizes, so that the product size is uniform and meets the standard, and the environmental protection production can be realized.
