In the ore beneficiation or ore dressing production line, the stone crushers or crushing machines are used in the coarse grain crushing stage. According to the equipment crushing methods and working principles, these crushers are mainly divided into four types: jaw crusher, cone crusher, and impact crusher.
1.Jaw crusher
it is a very old and widely-applied crushing machine. Its working principle goes like this: the electro motor drives the belt wheel to make the movable jaw up and down through the eccentric shaft; when the movable jaw goes up, the angle between it and the toggle pate is bigger, thus pushing it to get close to the fixed jaw, and at the same time, the materials are crushed or smashed.
2.Cone crusher
it is a continuous ore crushing machine and according to the feed size and the finished product requirement, cone crushers can be divided into rotary cone crusher, medium cone crusher and fine cone crusher. Based on the crushing cavity parallel band length, they are divided into standard type, middle type and short head type one.
3.Impact crusher
it is a new high efficiency and promising machine crushing machine featuring small size, simple structure, high crushing ratio, low energy consumption, high yield, evenly product particles and selecting crushing function.
