What’s the Difference Between Cone Crusher & Small Jaw Crsher in the Medium Crushing Process
In the stone production line, reasonable configuration of crushing equipment plays a very important role in increasing the output, improving the stone shape and particle size distribution.
The current process of the entire crushing production line basically includes three main stages: coarse crushing, medium and fine crushing, and screening. In the medium-fine crushing stage, cone crusher and small jaw crusher are the most used crushers. What’s the difference between cone crusher and small jaw crusher in the medium crushing process? Let’s take a quick comparison.
cone crusher vs small jaw crusher
The structure and principle of the fine jaw crusher are similar to that of the jaw crusher. The working mode is curved extrusion type, and the material is crushed in the crushing cavity composed of the movable jaw and the fixed jaw.
The cone crusher adopts laminated crushing, and the rolling mortar wall continuously moves to the crushing wall, squeezing the material sandwiched between the two to crush it.
1. Production characteristics
Generally speaking, fine crushing jaw crusher and cone crusher have the following characteristics:
1) The feed size range of the small jaw crusher is relatively large, and generally can handle materials below 1000mm, while the cone crusher is relatively strict, generally requiring less than 300mm (depending on the specific situation of the product);
2) In terms of processing capacity, cone crusher far exceeds fine small jaw crusher, generally up to 1000t/h, which is more than twice as high as fine jaw crusher;
3) In processing hard materials, the compressive strength of the two is basically the same, between 300-350Mpa.
2. overall structure
From the perspective of the overall structure, the cone crusher is 1.7-2 times heavier than the fine jaw crusher with the same feed size, and the machine is generally 2-3 times higher than the fine jaw crusher, so the cone crusher requires a bigger space.
3. Handling materials
The cone crusher is not suitable for crushing wet and viscous ores, and the fine jaw crusher can almost meet all kinds of materials.
4. Feeding requirements
5. Finishe product
(1) Cone crusher vs impact crusher
The impact crusher has a better grain shape and fewer edges and corners, and the cone crusher has more needles and flakes.
(2)Cone crusher vs fine jaw crusher
The cone crusher product generally has a slightly better shape.
Through the comparison of the above characteristics, we can know that the selection of medium and fine crushing equipment should be adapted to local conditions. Taking into account the cost of equipment, when the two types of equipment can meet the crushing needs and the required quantity is the same, we generally choose the fine jaw crusher; for large-scale factory production operations, the cone crusher should be selected; when crushing wet viscous ore, it is appropriate Choose fine jaw crusher; cone crusher is suitable when processing flake or long hard ores. The specific equipment selection still depends on the user’s production requirements.
