1. Jaw rock crusher VS gyratory crusher

Both of them are used for primary crushing and their crushing speed is 100-200 revolutions per minute. Their differences lie in two ways.

(1) Final product shape

The particle shape produced by the gyratory crusher is not as well as that produced by the jaw crusher. But the production of gyratory crushers is much higher.

If you only crush materials with more than 1000t/h and no special demands on the final particle shape, you can choose a gyratory crusher. It can be fed with two sides, which greatly reduces time and costs less.

(2) Installation and maintenance

A jaw crusher can be sectionalized, so it is advantageous to install a jaw crusher in remote locations, underground. Jaw crusher installation cost is higher than gyratory crusher while its investment and maintenance cost is lower than gyratory crushers.

2. Horizontal shaft impact crusher (HSI) VS cone crusher

(1) To process different materials

HIS performs better to crush soft materials like limestone, and the even and cubic- shape of the product is favored by concrete and asphalt manufacturers.

Cone crusher shows us its great value when crushing granite, pebble, marble, quartz, etc.

(2) Purchase and Maintenance

At first, you cost more on cone crusher than on impact crusher. But cone crusher does not need maintenance so much. Impact crushers' hammers and aprons wear quickly thus resulting in high repairing costs.

3. Roll crushers vs hammer crushers

Both are used in the secondary or tertiary crushing process but still have many differences.

(1) Materials

Roll crusher relies on its unique advantages such as less fine rate, low headroom, low horsepower, can handle materials like clay and marl with high humidity and viscosity.

In addition to crushing soft to medium hardness stones such as limestone and gypsum, a hammer crusher has unparalleled advantages in breaking glass.

(2) Maintenance

Roll crushers perform well on hard and abrasive material. The surface of the roller drum is smooth, which greatly minimizes the repair cost. Hammer crushers need more careful protection and maintenance.

4. Vertical shaft impact crusher(VSI crusher)VS roll crusher

(1) Product shape

VSI crusher is generally used for the third or fourth stage crushing, which is the final link of aggregate production. It is the best machine to produce manufactured sand even better than a roll crusher. The final product of the VSI crusher is cubic, which can replace natural sand.

Roller crushers can also be used for sand making, but the product shape is not as fine as VSI.

(2) Price

The product price of the two crushers is different. The price of a VSI crusher is much higher than a roller crusher.

Conclusion

To choose the best equipment, you need to do a comprehensive analysis of your projects, such as material characteristics (hardness, strength, humidity), worksite (in the city center or on the mountain, or other places), cost analysis, etc.

Different conditions will result in various solutions. If you need a more detailed analysis tailored to your crushing operation, please contact Fote Company's experts. The company has more than 35 years of design and practical experience, and it helps you to make the best choice.
