FAQs About Double Roll Crusher

1. What is double roll crusher?

Two parallel, counter-rotating rolls make up a double roll crusher, sometimes referred to as a twin roll crusher. Rocks, ores, coal, and other hard and medium-hard materials are frequently crushed into smaller, easier-to-handle bits using these wheels.
Feeding the material to be crushed into the gap between the rollers allows the revolving rolls to compress and crush the material. Double roll crushers are particularly helpful in situations where a uniform particle size is crucial since the crushing process results in a constant product size.
Double roll crushers feature a number of benefits, including a high output rate, adjustable gap settings to regulate the product size, a durable design, and broad industry applicability in the mining, building, and other sectors.
They are frequently utilized in the mineral processing, mining, coal handling, and other sectors where it is necessary to reduce bulk materials into smaller particles.

2. What is the difference between single roll crusher and double roll crusher?

The number of rollers and how they work are the main differences between a single roll crusher and a double roll crusher:
  • Count of Rolls:
A single roll revolves and smashes the material against a stationary breaker plate in a single roll crusher. Usually, applications requiring primary crushing employ this kind.
Two rollers in a double roll crusher revolve in opposition to one another to crush the material. The material is crushed into smaller pieces as it travels between the two rolls. For intermediate and tertiary crushing, double roll crushers are frequently employed.
  • Product Size Management:
Single Roll Crusher: Since there is only one crushing roll, it often yields bigger product sizes. The distance between the roll and the fixed breaker plate determines the size of the final product.
Double Roll Crusher: Provides greater control over the end product size due to the ability to precisely size the space between the two rolls.
  • Application:
Larger materials like coal and lignite are typically crushed in the initial stage using a single roll crusher.
Double roll crushers are employed in applications requiring accurate size, such as mineral processing and later stages of reduction, for secondary and tertiary crushing.
  • Capacity:
Compared to double roll crushers, single roll crushers typically have a lesser capacity.
Due to the two rolls’ cooperative operation, the double roll crusher has a larger capacity.
In conclusion, double roll crushers are better suited for secondary and tertiary crushing because they allow greater control over product size, whereas single roll crushers are excellent for primary crushing of bigger materials. The decision between them is based on the application’s particular requirements.

3. What is a jaw crusher used for?

Depending on the particular application, roll crushers might have a single roll or a double roll arrangement. Two rolls that revolve in opposition to one another make up double roll crushers, which offer a more effective and precise crushing operation.
Roll crushers operate on the idea of compressing and shattering the material between the rolls. It is a flexible crushing technique used to break down materials into more manageable bits in a variety of sectors, including mining, building, and mineral processing.

4. What is the difference between impact crusher and jaw crusher?

The kind of material to be crushed, the desired final product size, production capacity, energy efficiency, and the particular requirements of your application are all important considerations when choosing the optimum type of crusher. Here are some prevalent crusher kinds and the situations in which they work best:
  1. Primary crushing of hard and abrasive materials is best accomplished with a jaw crusher. It works well with a variety of substances, including rocks, minerals, and ores. In the mining, construction, and recycling sectors, jaw crushers are often employed.
  2. Impact crusher: Useful for crushing softer materials in the secondary or tertiary stages. Impact crushers may be used in mining, building, and recycling because of its adaptability and capacity to handle a wide range of materials.
  3. In the end, the cone crusher is excellent for crushing hard and abrasive materials in the secondary and tertiary stages. They are frequently employed to create fine and uniform-sized material in mining, quarrying, and aggregate manufacturing.
  4. Roll crushers: Typically employed in mining and mineral processing, they may reduce massive materials to sizes that are easier to handle.
  5. In industrial settings, hammer crushers are frequently used to break softer materials including coal, limestone, and gypsum.
  6. Vertical Shaft Impact Crusher (VSI): Excellent for making sand and cubical aggregates of excellent grade. frequently employed in the mining sector and the fabrication of produced sand.
  7. Double roll crushers are used to crush materials that call for exact sizing of the final product. frequently applied in mineral processing and mining.
  8. Cone/Gyratory Crusher: Typically used for primary crushing of hard and abrasive materials in large-scale mining and mineral processing operations.
  9. Cage Mill: Suitable for crushing low to medium abrasive materials, such as chemicals and fertilizers.
  10. Mobile crushers: Perfect for recycling building debris on the spot. They come in a variety of designs, such as cone, impact, and jaw crushers.
The best crusher type will rely on the particulars of your project as well as the properties of the material you need to crush. To choose the best crusher for your application, you must run tests or talk with professionals.

5. What is the capacity of crusher per hour?

30-200 tons/hour
