Granite is a common rock. Due to its high hardness, it is generally difficult for crushers to break. Even if it can be broken, it will cause greater wear and tear. Therefore, when choosing a granite crusher, you must choose the right one to avoid high Amount of repair and maintenance costs. It is also classic equipment.
Why do you choose cone crusher instead of hammer crushing for broken granite? This also starts with the difference between them
1. Applicable stage
The cone crusher is suitable for the medium and fine crushing stages and is often used in the second and third crushing links of the production line. Hammer crushers can be used for coarse crushing and sometimes fine crushing.
We had a customer who wanted to use a hammer crusher to crush granite. Indeed, a hammer crusher can be formed at one time without secondary crushing, but it is more common in small and medium-sized production lines and does not require a high finished particle shape.
2. Processing materials
Cone crusher is suitable for processing high hardness stones, such as iron ore, basalt, granite, pebbles, etc. It is ideal equipment for crushing hard ores.
Hammer crushing is suitable for processing medium and soft ores, such as limestone, coal gangue, dolomite, shale, etc. It cannot handle materials with high hardness, otherwise, the hammerhead wears quickly, and the frequency is better (using hammer crushing granite hammer Head replacement frequency will be higher).
3. Feed particle size
From the applicable stage of cone crusher and hammer crusher, it can be seen that cone crusher will have stricter requirements on feeding particle size. Generally speaking, the feeding particle size is about 300mm. The hammer crusher can be used for coarse crushing, and its feeding particle size can reach 1200mm.
4. Input cost
From the perspective of equipment price, the investment of a hammer crusher is lower than that of a cone crusher. Although the purchase cost in the early stage is not high, the replacement of wearing parts such as hammerhead in the later stage is also not a small cost, especially for crushing medium and hard materials. Relatively speaking, the worn parts of the cone crusher have a longer service life and less investment in the later period.
So in general, if the output is too large, it is still easy to choose a cone crusher.
