What is the difference between pulverizer and crusher? ›

In summary, while both crushers and pulverizers are used for size reduction, crushers are typically used for initial, coarse reduction of large, hard materials, and pulverizers are used for finer, more detailed reduction of a wider range of materials.

A typical impact crusher or other type of rock crusher uses a great deal of force to reduce the size of rocks. They operate on mechanical force for breaking apart the large rocks as opposed to chemical or laser methods of breaking rocks. In many cases, primary crushers are a part of a large materials handling system.

A rock crusher is used to break down rocks into smaller pieces. You can crush the rock into pieces that are your desired product size. Rock crushers are most often used for gravel, sand, cement, mining, construction/demolition waste (such as concrete and asphalt), and industrial recycling.

Jaw Crushers: Ideal for heavy-duty primary crushing applications. Cone Crushers: Perfect for secondary and tertiary crushing with precise output. Impact Crushers: Suitable for various stages with impactful reduction.

However, a disadvantage of portable pulverizers may be their potentially limited capacity compared to stationary ones, which can handle larger quantities of materials due to their fixed setup.

Small batches of soft rocks such as sandstone and caliche can be roughly broken up by a hydraulic breaker attached to an excavator. If the rocks are harder (granite and basalt) they will require more crushing power. A compact jaw crusher will be necessary for this job.

Compression-style jaw, cone, impact crushers, and gyratory crushers are most often appropriate as primary crushing equipment types, though there can be overlap between primary and secondary crushers as far as suitable types.

Jaw crushers are commonly used in mining, construction, and recycling industries. Impact crusher: This is a machine that uses high-speed impact forces to crush rocks or granite into smaller pieces. Impact crushers are commonly used in quarries, recycling, and mining operations.

The best type of crusher for hard rock is a jaw crusher. Jaw crushers can handle very large pieces of rock, and are able to produce a finely crushed product with a relatively small motor. They are popular in mining and quarrying applications, as well as in construction sites.

In general, jaw crushers have a maximum feed opening size of about 48 inches by 60 inches, but the actual size of the rocks that can be crushed may be smaller or larger than this depending on the specific crusher.

What is the best crusher for gravel? ›

Cone Crushers

They handle medium hard to very hard, abrasive materials that can be dry or wet but not sticky. Cone Crushers are typically found in quarried materials and sand and gravel applications. They provide a reduction ratio of 3:1 to 5:1.

In some cases, gravel is piled into blast furnaces and used as a flux. This gravel becomes a liquid slag that is allowed to harden into a stone material that's used as an aggregate for other construction materials. Indeed, the construction industry is the biggest consumer of gravel.

The primary difference between crushing and pulverization lies in the scale, method, and purpose of the size reduction process. Crushing typically involves the reduction of large, dense materials into smaller particles, often for disposal, recycling, or further processing.

Pulverizing is pressing or crushing something until it becomes powder or a soft mass. Grinding is making something into small pieces or a powder by pressing between hard surfaces.

Pulverizers (coal pulverizer) are used to pulverize pieces of coal into fine particles (100μm) before placing into a boiler, to ensure efficient combustion.

Soil pulverizers shatter hard, compacted ground and break down chunks of soil. They have a variety of uses, such as preparing gravel driveways for new rock, breaking ground for new gardens, and finishing seedbeds for landscaping or specialty crops.
