Jaw Crusher VS Gyratory Crusher

Both the gyratory crusher and the jaw crusher are used for primary crushing equipment in sand and gravel aggregates production plant. They are similar in function but different in overall dimension, capacity and cost. Let’s study the specific difference between jaw crusher and gyratory crusher.

1.Base weight

For gyratory crusher, its work is relatively stable and the vibration is light. So the basic weight of the machine is small. The base weight of the gyratory crusher is usually 2-3 times the weight of itself, while the base weight of the jaw crusher is 5-10 times the weight of the crusher itself.

2.Ease of starting

The gyratory crusher is easy to start, while the jaw crusher needs to use auxiliary tools to turn the heavy flywheel before starting (except for the segmented jaw crusher).

3.Finished product shape

The flaky products produced by the gyratory crusher are less than those produced by the jaw crusher.

4.Capacity

The depth of gyratory crusher is large, so the crushing work is continuous and the production capacity is high, and the unit power consumption is low. Compared with the jaw crusher with the same ore opening width, its production capacity is twice than jaw crusher, and the power consumption per ton of ore is 0.5-1.2 times lower too.

5.Feeding method

The large gyratory crusher can directly feed raw ore without adding ore bins or feeding machines. However, the jaw crusher cannot be filled with ore, and it is required to feed the ore evenly, so it is necessary to set up an ore bin (or ore hopper) and a feeder. When the ore size is greater than 400mm, it is necessary to install an expensive heavy-duty plate to the mining machine;

6.Investment cost

The weight of gyratory crusher is relatively large, which is 1.7-2 times heavier than jaw crusher with the same ore opening size, so the equipment investment cost is relatively high. Also The height of gyratory crusher is higher than jaw crusher too, so the construction cost is relatively large.

7.Maintenance

Installation of gyratory crusher are more complicated, and maintenance is also high requirement for professional engineers. As a common stone crusher, Jaw crusher is easier in installation and maintenance.

8.Applied material

The gyratory crusher is mainly used for coarse crushing of various hard material in the primary crushing stage, but it is not suitable for crushing wet and sticky ore. Jaw crusher can crush high moisture, sticky ore, and not easily blocked. Generally, the large scale mining process company more use the gyratory crusher, the small-sized mining process plant and quarry plant more to adopt jaw crusher

People also frequently asked for- FAQ:

Which type of crusher is best?

The basic crusher types are: jaw crusher, cone crusher, impact crusher roller crusher, hammer mill crusher, which are operating in different stage based on their character. The right crusher is the best stone crusher.

How do l choose a stone crusher?

To choose a suitable crusher, you’ll need to provide information about the material you plan to crush.
The abrasiveness and hardness of the material determine the compressive strength it can withstand before crushing. 
2. The material feeding size is to determine the size of the crusher required.
3. The finished material size is required to determine the number of crushing stages necessary to achieve the desired reduction.
4. Capacity (throughput) is measured in tons per hour. You will need to determine the processing capacity

What is difference between jaw crusher and cone crusher?

The jaw crusher is mainly used for primary crushing, and the crushed stone is relatively large. Cone crushers are used for crushing medium-sized stones fragment, and are mostly used for secondary crushing.
