Primary Crusher - 4 Types and Usage

A primary crusher converts shot rock into usable products. Crushing reduces large rocks into small pieces. Which is also used to convert rocks into fines remain. A primary crusher is simply employed in crushing in certain operations. And a tertiary crusher and a primary crusher are utilized together in other operations.

What are the different types of primary crushers? Autogenous crushers, gyratory crushers, jaw crushers, and impact crushers. There are plenty of similarities from the job they actually do. Every one of these primary crushers reduce rocks to more manageable sizes.

Here are the different types of primary crushers along with their uses.

1. Jaw Crusher

A jaw crusher has two metal surfaces. This crusher uses these surfaces to squeeze rock between. One surface opens and closes such as a jaw. Rocks enter this crusher from your top. You will find a narrow opening towards the bottom from the jaw. Rocks, that happen to be bigger than this opening, lodge involving the two metal surfaces.

The movable jaw opens and closes from the fixed jaw. The closing and opening action reduce the rocks that are lodged between your two metal surfaces. These rocks are reduced until they are small enough to fall through the narrow opening at the bottom on this crusher.

2. A Gyratory Crusher

Furthermore, it breaks rocks. It squeezes rocks between an eccentrically gyrating spindle. Enclosing concave hopper and a wear-resistant mantle covers this spindle. The rock enters gyratory crusher through the top. The rock becomes wedged. And the mantle and hopper squeeze the rock.

Big rocks are split up into small pieces first. Then, the little pieces of the rocks fall for the lower position. These small pieces are further divided into smaller pieces. This is how a gyratory crusher fails big rocks into small pieces.

3. Impact Crusher

Impact crushers are also referred to as hammer mills. How can an impact crusher break a rock? It impacts the rock with hammers. The hammers swing over a rotating shaft. However, a positive change crusher is only employed to break soft materials like weathered shales, gypsum, phosphate, etc.

The great news is that this impact crusher makes a finer sized product. But it really cannot handle big rocks along with other large or top sized materials. This crusher(trituradora de piedra de rio) was created as primary, secondary, or tertiary rotor crusher, but this is dependent upon the processing stage that the crusher can be used.

4. Autogenous Crusher

This crusher is made to crush run-of-mine rock in primary crushing circuits. Autogenous crushers are usually useful for grinding and crushing. The rock, which is being crushed, offers the crushing force.

How is crushing accomplished in an autogenous crusher? It uses the tumbling action of the rock. And possesses flexible crushing circuits that process hard ores and soft ores. Also, an autogenous crusher is perfect for processing wet and sticky ores. This crusher is energy efficient and it may handle abrasive ores.

These represent the different types of primary crushers. These crushers are used to crush rocks into small pieces. You additionally know the uses of those crushers, so go with a primary crusher which fits your job.
