Small crushers are usually used to crush solid samples in laboratory, but how can we choose suitable ones?
1. Crushers for High humidity solid materials
We have tested and find that hammer crusher can crush materials with moisture content less than 25%, while jaw crusher can crush materials with moisture content less than15%.
hammer crusher is more suitable to crush high humidity solid materials
2. Working Efficiency
We will use a jaw crusher and hammer crusher with the same inlet size to test, the materials we used is around 25mm, we will set the output size as 5mm.
Materials are put in the crushers by a mini belt conveyor, jaw crusher can produce 2 tons per hour while hammer crusher
can produce 500kg. Even the crushing ratio of jaw crusher is about 60%, it is more efficient than hammer crusher.
3. Evenness of final product
Crushing ratio of jaw crusher is 60% while hammer crusher is 100%. Hammer crusher is better to get evenly final product
4. Feeding size
To compare the capacity of hammer crusher and jaw crusher with same inlet size. The biggest materials jaw crusher can crush is 80mm, but hammer crusher can only crush materials smaller than 30mm.
5. Finest output size
Distance between the jaw place can not be smaller than 2mm, or else they are easy to bump each other, what is more, the big materials may block the outlet. The finest size jaw crusher can do is around 4mm.
The output size of hammer crusher is depend on the sieve plate. The finest sieve hole is 1mm. That is to say, final product bigger than 1mm can not get out of the crusher and will be recrushed.
Hammer crusher is better than jaw crusher in fine crushing.
