Abstract
The utility model relates to a single roller driven double-roll crusher. The utility model relates to a roll crusher and a high pressure roll grinding machine which are used for crushing materials in industries of mine, metallurgy, building materials, etc. The utility model is characterized in that a fixed roll which is a minor diameter roller body is provided with a transmission device, and a movable roller with a major diameter rotates by the friction of crushing materials and is not provided with a transmission device. The utility model has the advantages that systems are simple, the crushing of the materials of different grain sizes, hardness, toughness or brittleness are adapted by the optimum design of the diameters of two rollers, the purpose that energy is saved can be also achieved.
Description
Technical field
The application relates to the kibbler roll and the high-pressure roller mill of the broken usefulness of industry materials such as mine, metallurgy, building materials.
Technical background
The present kibbler roll that uses is at the textural pressure apparatus that roll body that frame, two diameters are identical and hydraulic cylinder constitute etc. that comprises.Two kinds of forms are arranged on Cracking Mechanism: a kind of is the simple grain fragmentation, and another kind is the lamination fragmentation.So-called lamination fragmentation is to transmit pressure by between the material of fracture area, squeezes material particles broken; What the simple grain fragmentation was leaned on is that roll surface contacts with treating the direct of broken material interblock, will expect the piece crushing.Which kind of Cracking Mechanism no matter, double-roll crusher (smooth roll or discaling roll) all adopts two roller drive forms at present, and promptly two rollers all have power, and the while is with fast incorgruous rotation.There are the two rollers drivings of bi-motor, single motor to add the two rollers of transmission mechanism and drive (disintegrating machine one end is established transmission mechanism); Wherein a breaker roll is a stationary roll, and its bearing block is not removable, and another breaker roll is that the movable roll bearing block is removable, by the hydraulic cylinder of two end axles bearing back movable roll is pressed to stationary roll.Any drive form no matter, two rollers are all dynamic, make system architecture comparatively complicated.When particularly roll gap pressure was high, the synchronism that the movable roll bearing block moves required comparatively difficulty of height, control; When coming material granularity irregular, can not moment the autobalance rotating speed, efficient is low, power consumption is big.In actual applications, the design people finds that the passive rotation of frictional force that this roller still can lean on material to transmit does not influence feed function and crushing effect when the power failure of certain roller, and production efficiency is not low.Therefore the designer is subjected to the inspiration to the application.
Summary of the invention
The application's purpose is under the prerequisite that does not influence feed and crushing effect, designs the double-roll crusher that the low single roller of the simple power consumption of a kind of system architecture drives.
Technical scheme is that a major diameter roller and a minor diameter roller are installed on frame, and the minor diameter roller is a stationary roll, and by power transmission, the major diameter roller is a movable roll as drive roll, is driven by drive roll as driven roll (free roller) and rotates.During disintegrating machine work, drive roll arrives driven roll by broken material with transmission of power, and two rollers are rotated in opposite directions.
The application is optimized design at the physical characteristics such as different grain size, hardness, toughness or fragility of material to two breaker roll diameters, and the diameter ratio is generally 1: between the 1.2-5.0.
The application's good effect is: owing to only power is set on stationary roll, make system architecture simple.Driven roll is in the self adaptation state all the time during work, can be according to the crushing force size, fracture area raw meal particle size, hardness, moment relative position situation etc., regulate rotating speed automatically, reach the best crushing effect of material.The fragmentation of this moment is not merely the crushing of general meaning, and also have a power (drive roll by this power drive driven roll rotation) vertical with the pressure action direction, the acting in conjunction of two power helps material particles shear fracture (although the lamination fragmentation is the particle redistribution shattering process of a complexity), help material bed middle particle redistribution to move, pass through optimal design again to two roller diameters, therefore, the application's disintegrating machine is than at present common two high pressure roller mill engine efficiency height that drive, it is low to consume energy, broken through the anti-skidding design philosophy of only considering at present of tooth angle, can avoid simultaneously the material bed pressure rolling of crossing from rubbing angle.
Description of drawings
Fig. 1 is the application's a structure vertical view.
Marginal data: 1-frame, 2-initiative roll shaft bearing, 3-drive roll, 4-side shield device, 5-driven roll bearing block, 6-driven roll, 7-hydraulic cylinder, 8-crusher chamber, 9-power set.
The specific embodiment
As shown in Figure 1, be placed with drive roll 3 and bearing block 2, driven roll 6 and bearing block 5 thereof in frame 1 framework.Be placed with hydraulic cylinder 7 between driven roll bearing block 5 and frame 1 column, hydraulic cylinder 7 provides pressure that driven roll bearing block 5 is pressed to initiative roll shaft bearing 2, also is about to driven roll 6 and presses to drive roll 3, and this power promptly equals the pressure of broken material.Initiative roll shaft bearing 2 is fixed in the frame 1, can not move, and driven roll bearing block 5 is in quick condition in frame 1, can move forward and backward according to crusher chamber material situation and cracking pressure size.Drive roll 3 one axle heads are connected with power set 9, and power set 9 comprise reductor, motor etc.Side shield device 4 is fixed on the frame 1 at drive roll 3 and driven roll 6 two ends, constitutes crusher chamber 8 jointly with two roll surfaces.
Claims (2)
1. double-roll crusher that single roller drives, it comprises frame, stationary roll, movable roll and pressure apparatus, it is characterized in that being provided with on stationary roller shaft drive unit, movable roll is that driven roll is not established drive unit, and drive roll drives driven roll by the material friction and rotates.
2. kibbler roll as claimed in claim 1 is characterized in that the drive roll diameter less than the driven roll diameter, and according to the physical characteristic of material, the diameter ratio is 1: between the 1.2-5.0.
