Sand Making Machine Production Line With Gyratory Crusher

Sand Making Machine Production Line With Gyratory Crusher

Everyone said that smashing is the first choice for rough equipment. Why does a large-scale sand making machine production line use a gyratory crusher? The reason is all here. In everyone's understanding, the coarse crushing equipment in the sand making machine production line mostly choose jaw crushers, small-scale mines sometimes use crusher crushers, and the medium and fine crushing processes mainly use cone crushers and vertical shaft crushers to achieve the fine crushing of ore. Or plastic surgery.

However, at present, more and more large-scale gravel production lines have begun to select gyratory crushers for rough-breaking equipment, such as coarse crushing of large-scale hydropower plants in China (Mianhuatan Hydropower Station). why? The following comparison of the eight aspects of the gyratory crusher and the jaw crusher is clear.

1, production capacity and energy consumption

  1. From the crushing principle, the gyratory crusher is continuously broken, with high productivity, stable operation, and low energy consumption. Jaw crusher is discontinuous and intermittent crushing, and has low productivity and high energy consumption.
  2. The broken loop can be filled with ore, and the processing efficiency is higher;
  3. The gyratory crusher has a crushing ratio of 6-9.5, and individual conditions are 13.5. It is suitable for use in factories with large production volumes and in the material-collecting field. It is not as good as gyration, but it is generally a small-scale concentrator and quarry. Such as the use of smashing broken as the first paragraph.

In general, the single-cycle capacity of the gyratory crusher is larger than the jaw crusher, and the average energy consumption of the medium-sized gyratory crusher is much lower than that of the large and medium jaw crusher. This is also the main reason why many large-scale sand making machine production lines use gyrations.

2, the finished product granularity

  1. he gyratory crusher has a relatively uniform particle size and is suitable for crushing sheet materials. Jaw crusher's product granularity is not as good as the gyratory crusher;
  2. In the finished product particle size composition, the particle size of the material that exceeds the width of the discharge port after crushing by the crusher is smaller than that of the jaw crusher, the quantity is also small, and the particle size is relatively uniform.

3, wear parts life

Gyratory crusher adopts the principle of laminar crushing between materials, and has a longer service life than wear parts of jaw crushers. Jaw crusher mainly adopts the principle of impact crushing and crushing. The discharge is mostly flat, sharp or triangular needle-shaped particles, the content of which exceeds 20%, and the jaw plate wears quickly.

4, production costs

Compared to jaw crushers, gyratory crushers are tall, complicated in structure, expensive, and difficult to maintain, but in coarse crushing processes, the cycle reduction can reduce staffing by 50%, 30% maintenance, and 15%. Energy consumption simplifies on-site management; in the crushing process, the gyratory crusher can save 20% maintenance fees and 5% energy consumption. In actual production, the annual cost savings can be about 15%, and the economic benefits are significant.

5, the feeder configuration

Smashing as a rough-breaking device requires the front to be configured with a feeder. For a gyratory crusher, it can be packed full of ore, and raw materials can be poured directly from the vehicle into the infeed, eliminating the need for feeders, streamlining processes, and reducing cost.

6, the cost of mining

The mining process mainly uses deep-hole blasting technology, in which the drilling process uses a down-hole drilling machine. After blasting, large blocks of stone must be impacted to meet the crusher feed requirements. The feed size of the jaw crusher is small, which results in a higher density of blasting holes and a greater consumption of explosives. After the blasting, there are more large blocks of stone with a size of more than 900 mm, and the impact crushing workload is large.

7, operation and maintenance

Jaw crusher has the advantages of simple structure, low manufacturing cost, convenient maintenance and inspection, reliable work, and small sand making machine height. The gyratory crusher is bulky, cumbersome, inconvenient to carry, and more complex to operate and maintain. However, with the development of technology and economy, large-scale sand production line equipment is equipped with a unified intelligent management system that can automatically detect failures.

8, environmental protection

In contrast, jaw crushers have a large amount of dust emission, and are scattered and difficult to close, resulting in poor working conditions and environmental pollution.

To Sum Up

Crude crushing process is one of the key links affecting the technical upgrading of the mechanism sand producer. Compared with jaw crushers, although the gyratory crusher is complex in structure, large in size, and high in initial investment, it has obvious technical and economic advantages in view of the efficiency of large-scale production and long-term operation cost, and is adopted by large-scale mechanism gravel plants. Recycling can also effectively increase the level of mining and coarse crushing technology and reduce the overall production cost.

However, it does not mean that it is more advantageous to choose any cycle. If the two models can meet the requirements from the aspects of supply, discharge granularity and exit rate, they can be broken according to the medium and fine crushing used in the process. Machine, investment, infrastructure, and other measures to determine. According to experience, if a jaw crusher can meet the production requirements when it is selected, it should be smashed. If two smashing crushers are needed, one gyratory crusher should be considered. If the viscous material is handled, smashing is more applicable. In actual production, the user needs to select equipment according to specific production conditions.
