Abstract

The utility model relates to a double-cavity jaw-roller type fine disintegrating machine, composed of a machine frame, an eccentric shaft, a jaw roller, a fixed jaw plate, etc. The eccentric shaft is driven to rotate by a speed reducing motor, enabling the jaw roller to do swivel motion with upside down and laterally reversal swing to realize the goal of crushing materials. The usage of the crusher alters the intermittent crushing operation of traditional jaw crushers and single lumen crushing working condition with the crushing efficiency increased by 1.5-2 times, the power consumption decreased by 30-50 percent and homogeneous granularity. Because the eccentric shaft and the jaw roller are rotary rolling structures, almost no sliding friction exists between the surface of the lining plate of the jaw roller and the material, and consequently, the rate of wear is reduced and the service life of the lining plate is extended.

Description

Two-chamber pre-roller type fine crushing machine

The utility model relates to a kind of disintegrating apparatus, is mainly used in the fine crushing to lump material, can be widely used in industrial trades such as building materials, metallurgy, chemical industry, is particularly useful for the clinker in the cement industry is carried out fragmentation.

Prior art may be summarized as follows: traditional disintegrating apparatus, be broadly divided into jaw crusher, hammer mill, impact breaker, rotary crusher, centrifugal impact crusher etc., because structure difference, use occasion is also different, respectively have different pluses and minuses, but for material hard as clinker, use above-mentioned several disintegrating machine, all exist material to tup, grate plate, wearing and tearing such as liner plate are violent, the easy mill spare that has only uses and just lost efficacy in several days, needs to change, and this not only causes use cost very high, also influence ordinary production, bring big inconvenience to Operation and Maintenance.And jaw crusher, though the service life of jaw is longer, product granularity is very big, generally reach 25-30mm, do not satisfy in next step grinding process process the requirement that improves output and reduce power consumption, equal should being finished by disintegrating machine of task is pushed away to next stage milling equipments such as ball mills.A kind of disintegrating machine that can handle the material of fragility difference is provided, and is the problem that people study always.

The purpose of this utility model, it is the fine crushing machine that a kind of new construction will be provided, the material of the fragility difference that the broken similar clinker of this fine crushing prow elder generation's energy is such, and can guarantee that product granularity is below 5-15mm, and it is low to have a power consumption, and the wear-out part long service life is simple and reliable for structure, convenient operating maintenance, every performance indications are better than general jaw crusher.

The primary structure of two-chamber jaw roll crusher of the present utility model is characterized as, center in the frame inside that has charging aperture and discharging opening, utilize reducing motor to drive an eccentric shaft motion, outside at eccentric shaft, it is jaw roller by the bearing suit, the motion of eccentric shaft makes the jaw roller do motion up and down, on the both sides of jaw roller, decides the jaw jaw for two that are mounted on the frame.Because the motion of eccentric shaft constantly changes two distances of deciding between jaw jaw and the jaw roller.When material was fallen between jaw and the jaw roller, material just constantly was subjected to the extrusion shearing effect of jaw roller, thereby reached the purpose of broken material.

Use the utility model to have the following advantages.At first, in shattering process, the extruding of the pulsatile impact that is subjected to for a supplies of unit and shearing-crushing and be to be subjected to continuous extruding and shearing-crushing to the material in the whole crusher chamber, and because utility model adopts the double crashing cavity structure, changed the operating mode that jaw crusher is interrupted crushing operation and the fragmentation of single chamber, so crushing efficiency of the present utility model is 1.5-2 times of jaw crusher, power consumption reduces 30-50%, and product granularity is even.Secondly, eccentric shaft of the present utility model and jaw roller are the revolution rolling structure, can guarantee that the liner plate surface of jaw roller in shattering process is similar to fricton-tight friction with material, so wear liner speed reduces greatly, make liner plate have long service life.The 3rd, the jaw roller is continuously the revolution crushing operation, and the main shaft stressing conditions is interrupted broken alternate load situation than jaw crusher and makes moderate progress the machine operation balance.The 4th, the utlity model has simple and reliable for structurely, characteristics such as convenient operating maintenance make to be installed easily.

Most preferred embodiment of the present utility model can provide in conjunction with the following drawings.

Fig. 1 is a complete machine structure schematic diagram of the present utility model.

Referring to Fig. 1, two-chamber pre-roller type fine crushing machine of the present utility model by frame 7, eccentric shaft 10, jaw roller 2, decide jaw jaw 4, charging aperture 1, discharging opening 8, regulate safeties 6 etc. and form.Its assembly relation is, above frame 7, be provided with charging aperture 1, below frame 7, be provided with discharging opening 8, in the center of frame 7 are eccentric shafts 10, eccentric shaft 10 is installed on the frame 7, and an end stretches out frame 7 and links to each other with reducing motor (not drawing among the figure), and drives rotation by reducing motor.In the outside of eccentric shaft 10,, be set with jaw roller 2 by bearing 9, jaw roller 2 can be done with eccentric shaft 10 and relatively rotate, and on the surface of jaw roller 2 abrasion-proof backing block is housed, to reduce wear, under the rotation of eccentric shaft 10 drove, jaw roller 2 did to have the gyration of bobbing and weaving.Bearing 9 of the present utility model recommends to adopt entad sphere row roller bearing of biserial.Go back left and right symmetrically is equipped with two and decides jaw jaw 4 in frame 7 inside, the upper end of deciding jaw jaw 4 hangs fixing by the bearing pin 3 that is fixed on the frame 7, the lower end is by regulating and safeties 6 supports, adjusting and safeties 6 also are installed on the frame, regulate the distance of deciding between jaw jaw and the jaw roller 2 by it, with the granularity of control discharging.Also have simultaneously run into can not be broken hard material the time, make and decide the insurance function that jaw jaw 4 retreats.

The utility model can need to be designed to different size with different material characteristics at different output, but usually, for assurance has crushing effect preferably, the ratio of the eccentric throw of the external diameter of jaw roller 2 and eccentric shaft 10 should be controlled between the 100-200.

In order further to strengthen crushing effect, the utility model is also recommended the contact-making surface on jaw roller 2 surface abrasion resistance liner plates and material surface is designed to be profile of tooth, and be designed to can intermeshing complementary structure in the relevant position that will decide jaw jaw 4.

The utility model is when work, material is entered in the machine by charging aperture 1, divide and be scattering into the crusher chamber 5 of deciding formation between jaw jaw 4 and the jaw roller 2, because the rotation of eccentric shaft 10, make jaw roller 2 rotary oscillation up and down in crusher chamber 5, material in the crusher chamber 5 is produced extruding and shear action, make material, discharge from discharging opening 8 at last by progressively broken.
