The Roller Crusher mainly crush materials upon rotary move comparatively, since constant upgrading and improvement, it has more riper manufacturing technology. Moreover, the equipment has a simple structure, less over-crushing phenomenon, and the tooth shape, size and arrangement on the roller surface can be changed with the material properties.
Principle: mining materials are crushed by the roller wheels when they squeeze each other.
Main processing materials: coal (it also could be used in sand making, but has a smaller capacity than sand making machine.)
It is widely used in coal ore, cement, metallurgy, chemistry, building materials for sand making of the medium and fine crushing of ores and rocks with medium-hardness.

For roller adopts two sets of single drive roller, when users start the crusher, two roller rotate along relative direction, forming a "V" type of crushing cavity. The materials from the hopper are sent into the crusher at suitable quantity, then enters the two rollers along the tangential direction. Due to the gap in the middle of two rollers is small, and the system strength is greater than the material (but the high hardness material would not make the gap between rollers get larger or change operation state of roll road), so the materials squeezed in the middle of the two rollers will be crushed into smaller particle size with the rotation of the roller, and then enter the bottom of the machine with the rotation of the roller, and flow out of the machine from the slotted groove to complete the whole crushing process.
In addition, the distance between the two rolls of the crusher is the width of the discharging mouth, which determines the acceptable size of the crushed material.
The discharging granularity often is the big concern for customers, because many manufacturers wold produce rough granularity, which badly influences products’quality, to solve these problems, our HXJQ optimizes the Roller Crusher, and achieve the automatic control on adjusting feeding size, in which wedge-shaped adjusting device is arranged in the middle of the two roller wheels, and an adjusting bolt is arranged at the top of the wedge-shaped device. The user can adjust the bolt to pull the wedge up or down to adjust the granularity of the material, which greatly meets the diverse needs of users on the granularity of the product and improves the quality of the product.
The Roll Crusher is mainly composed by roll wheels, bearings supporting roll wheels, pressing, adjusting and driving units.
The top of the wedge device is equipped with an adjusting bolt. When the adjusting bolt pulls the wedge up, the wedge will move to the top of the roll wheel away from the fixed wheel, that is, the gap between the two rolls becomes larger and the discharge grain size becomes larger. When the wedge is down, the gap between the two rolls becomes smaller under the action of the pressing spring, and the discharge grain size becomes smaller.
By two motors, through the triangular belt drive to the groove wheel to drag the roll wheel, in accordance with the relative direction of motion rotation. When crushing the material, the material passes through the roll from the feed port and is crushed by rolling, and the finished product after crushing is discharged from the bottom frame.
The whole machine is made of high quality wear-resistant materials, especially the roller, the roller can be used repeatedly, the failure rate is low, can bring long-term benefits for users.
The Roll Crusher can achieve “larger crushing rate, less crushing times”by reducing feeding size and quality standard of mineral materials, which has improved products’shape, as well as enhance its crushing quality, actualizing the purpose of high capacity and low consumption.
Production advantages: the Roller Crusher only needs a small working area, and is easy to mobile, which effectively save much cost for users. It acquires a reasonable design, whose motor is separated from the crushing chamber to avoid corrosion or collision damage to the motor. The main feature is that it can crush materials with less than 8% moisture content so that they will not be blocked.

The crushed stones can be used as aggregate in construction, building, road, highway, railway and other industries. The high crushing efficiency and high quality final product meet the market demands, bringing economic benefits.
The demand of the market on aggregate and artificial sand in many industries has become more and more urgent.
There are rich stones and rocks in many countries, after processing, high economic benefits.
The final aggregate can be for own use or re-sell to other industries.
