? Usage and application of Roll Crusher :
1). Roll Crusher has many names such as roller crusher, double roller crusher and double-geared roller crusher.
2). Roll Crusher is mainly made up of roller, supporting part of the bearing, clamping and adjustment means, drive device and so on.
3). Roll Crusher can be used for the medium and fine crushing of all kinds of ores and rocks with high and medium hardness in many industrial departments such as ore beneficiation, chemistry, cement, refractory, abrasive materials and building materials.
? Features of double roller crusher :
1). Roll Crusher has the features of simple structure, and takes up smaller space, and the operation and maintenance of this machine is very convenient.
2) . Double roll crusher is equipped with safety protection device.
3). Roll Crusher working long life, almost no wearing parts.
4). The operational cost is low, stable operation, high efficiency, saving energy, high crushing efficiency.
5). There is equipped dust proof plant inside the machine and the sealing ability is excellent, so that thereis little powder dust and lower working noises, so that the working environment is greatly improved.
6). The gap of the roll can be adjusted according to the requirement of the customers .
? Working principle of double roller crusher :
1). The materials to be crushed fall from the feeding mouth to the space between the two rolls.
2). After being squeezed and crushed, the final products will naturally fall.
3). When there are too hard materials or materials that cannot be crushed, the rolls of the roller crusher will automatically withdraw under the effect of hydraulic cylinder or spring to increase the gap between the rolls, and the too hard materials or the materials that cannot be crushed will fall down,
4). Thus protecting the machine from being damaged. There is a certain gap between the two rolls that rotate at the opposite direction, and the maximum discharging granularity of the final products can be controlled by changing this gap.
5). Roll Crusher's the materials by relying on the two round rollers rotating at the opposite direction, and four-roll crusher crushes the materials by relying on the two pairs of round rollers rotating at the opposite direction.
