Description
Technical field
The present invention relates to mining machinery field, more particularly to a kind of double-roll crusher.
Background technology
Double-roll crusher (oppositely rolling roller crusher double-roll crusher double-roll crusher) is applied in mine ore, cement, chemical industry, electric power, metallurgical, building materials, the industrial departments such as refractory material crush medium-hard material, such as lime stone, clinker, coke, it is broken in the materials such as coal, operation in small, broken bits.
The parts such as the serial oppositely rolling roller crusher is mainly made up of disk roller, disk roller spring bearing, compression and adjusting means and drive device form.
The regulation of discharging-material size:Equipped with wedge shape or pad adjusting means between two disk rollers, the top of Wedge device is equipped with adjustment bolt, when voussoir is pulled upwardly by adjustment bolt, movable disk roller is lifted off fast pulley by voussoir, that is two disk roller gaps become big, and discharging-material size becomes big, when voussoir is downward, movable disk roller two-wheeled gap in the presence of holddown spring diminishes, and discharging-material size diminishes.Gasket device is quantity by increasing and decreasing pad or thickness to adjust discharging-material size size, and when increasing pad, two disk roller gaps become big, and when reducing pad, two disk roller gaps diminish, and discharging-material size diminishes.
At present, double-roll crusher is in use, when blanking is uneven, the roller of skew, due to can not moment autobalance rotating speed, cause crusher in crushing raw meal particle size uneven, crushing efficiency twist it is low.
The content of the invention
The goal of the invention of the present invention is：For above-mentioned problem, a kind of double-roll crusher is provided, by setting two groups of spring mutual cooperations to act on, accelerate roller autobalance rotating speed, existing double-roll crusher is solved because autobalance rotating speed is slow, causes crusher in crushing raw meal particle size uneven and splits the problem of broken efficiency is low.
The technical solution adopted by the present invention is as follows：
The double-roll crusher of the present invention, including body and the broken roller group that is arranged in body；The broken roller group includes active roller group and driven roll is rented, and the drive roll roller group includes initiative roll shaft and the active roller with it by key connection；The passive roller group driven roll axle and the passive roller with it by key connection;The initiative roll shaft and passive roll shaft both ends are erected on body by bearing block, and the axial line of the initiative roll shaft and passive roll shaft is the same as in a plane and being parallel to each other；Groups of springs one is provided between the active roller group and passive roller group, groups of springs two is provided between passive roller group and frame；The groups of springs two is connected to pressing device.
Further, the initiative roll shaft is identical with the size of passive roll shaft；The drive roll is identical with the size of driven roll.
Further, the groups of springs one includes two springs, respectively between the bearing block at initiative roll shaft and passive roll shaft both ends, and is connected with bearing block.
Further, the groups of springs two also includes two springs, and respectively at the bearing block at passive roll shaft both ends, its one end is connected to bearing block, and the other end is connected with pressing device.
Further, the pressing device includes adjusting screw rod and pressure strip, and the adjusting screw rod is provided with two groups, is connected to the both ends of pressure strip.
Further, the adjusting screw rod and the center line of groups of springs two are same point-blank；The adjusting screw rod is also associated with regulation handle.
Further, state adjusting screw rod and be provided with size scale.
Further, the spring is spiral spring or air spring.
Further, the spring is replaced by can reach the same hydraulic cylinder mechanism for compressing return effect.
Existing disintegrating machine to different size of material block when crushing, after driven roll can be offseted to one side due to larger material block extruding, because driven roll does not have direct drive unit connection, its velocity of rotation together drives by drive roll and fragment block entirely, therefore the driven roll rotating speed in migration process has a certain impact, while also has considerable influence to the crushing efficiency of whole crusher in crushing material block；And the double-roll crusher of the present invention, due to using said structure, by being also provided with groups of springs between two rods, so that groups of springs one and the collective effect of groups of springs two, driven roll moment autobalance rotating speed is realized, accelerates the regulation rhythm of disintegrating machine so that crusher in crushing efficiency uprises；And because groups of springs one is after stretching is received, a return clamp force will be produced, such active force also increases the crushing force of disintegrating machine while driven roll returning quickly is made, so that the material block that is broken is easier to be broken, the uniformity of broken material block is improved, also improves the production efficiency of disintegrating machine.
Due to that can also be adjusted using said structure, double-roll crusher of the invention by adjusting to compress to fill to the size of broken material, adjusting screw rod is provided with size scale, the structure design, ensure that the adjusting means adjustable range at both ends is consistent；And due in actual use, spring has failed because of long-term use of phase thrust, it is different that different springs plays deformation, two groups of springs are adjusted respectively using two groups of adjusting screw rods, it also ensure that two groups of springs are adjusted correspondingly during later stage use because deformation is different, the durability of spring mechanism is improved, is avoided and is excessively frequently changed spring assembly and cause to use upper inconvenience.
In summary, by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1st, the double-roll crusher is simple in construction, workable.
2nd, by being additionally arranged spring mechanism between two rollers, disintegrating machine autobalance rotating speed is realized, improves the crushing efficiency of disintegrating machine.
3rd, the groups of springs structure set up causes the crushing force of disintegrating machine to increase, and improves the uniformity of broken material.
