Is there such a device available?

The ore is crushed using a pair of rollers. After passing through these rollers, the ore is compressed into flaky pieces that can be separated with a gentle touch; most of the ore has been crushed to a particle size that meets my requirements, but it remains in flaky form and cannot pass through a sieve. What equipment can be used to break it up and loosen it, so that the ore can pass through a sieve?
“The ore is compressed into flaky pieces that can be separated with a slight rubbing of the hands.” I’m not familiar with the actual situation. Could a vibrating screen be used to break up those flaky pieces and allow them to pass through the sieve? If it is still too hard and cannot pass through the sieve, consider secondary crushing
I’ve used a vibration sieve, but it wasn’t able to separate them either.
A pendulum crusher will definitely meet your needs.
Roll crusher grinding is used for coarse crushing, followed by the selection of fine powder based on the desired fineness.
Since the Kun-type crusher cannot meet your requirements, you can use another type of crusher. You can try using a toothed roller crusher.
I’ve encountered this problem as well; the tablets produced by the roller press do not have the desired particle size, and the vibrating screen only serves to sieve, not to crush. The owner needs to select an appropriate crusher based on the properties of your materials and the required particle size.
9# lemon508 Thank you! The reason for choosing a roller mill is mainly due to operational cost considerations. There are many devices available for crushing soil; ball milling and Raymond milling have both been considered. Wet ball milling imposes limitations on the processing process, while dry ball milling and Raymond milling require the soil to be dried first before it can be ground, which is not practical at all, and the operating costs are also high. Not far from our company, there is a factory that uses dry ball mills; it has a production line with a capacity of over 200 kilowatts. Whenever the moisture level in the soil is slightly high, the material sticks to the walls, and workers have to use hammers and steel bars to break it off. Later, it was not possible to use the drying equipment in the kiln.
It seems quite difficult. Try traditional ball milling; your material is similar to dried cement powder.
