Abstract

The utility model discloses the roll crusher, comprising at least two main shafts arranged in parallel. A crushing roller with a plurality of convexes and concaves is positioned on each main shaft. The convexes and concaves are distributed in a wave-like way in the upward direction along the crushing roller shaft and the convexes and concaves positioned on the two adjacent crushing rollers are anastomotic with each other, leaving intervals between them. In operation, the crushing roller rotates while the fixed matching parts keep still; the materials above the crushing roller go through the intervals between the crushing rollers, during which process the materials are squeezed, torn and crushed. Due to the wave-like distribution of the convexes and the concaves, the contact area of the crushing materials is effectively enlarged, which not only helps to crush the materials, but also can tear the materials apart. The utility model has the advantages of low-decibel noises, large amount of production, low electric consumption each unit ton materials. The roll crusher can be applied to crush food, feed and other materials.

Description

Kibbler roll

Technical field

The utility model relates to a kind of machinery with the material fragmentation.

Background technology

What at present, be used on the market that grain and oil, feed pulverize mainly contains kibbler roll, beater disintegrating machine etc.Kibbler roll mainly relatively rotates by two pair rollers, produces extruding force, and material is pulverized.Beater disintegrating machine mainly by the high speed rotation of rotor, produces being used for of impacting to material and pulverizes; Beater disintegrating machine, rotating speed are very high, and be very high to the requirement for dynamic balance of rotor, and noise is very big simultaneously.

Kibbler roll mainly comprises and is arranged on two mutual parallel main shafts on the same horizontal level, be respectively arranged with breaker roll on the main shaft, breaker roll has two kinds of forms of roller of smooth roll and band axial tooth, and is approaching mutually between two breaker rolls, in the course of the work, two breaker roll contraries are to rotation, and material is rolled fragmentation from the gap process between two breaker rolls, because the contact area of breaker roll and material is little, therefore, its output is not high all the time, and efficient is lower.

The utility model content

Technical problem to be solved in the utility model provides that a kind of noise is low, output is high, the low kibbler roll of unit ton material power consumption.

For solving the problems of the technologies described above, the kibbler roll that provides of the present utility model, comprise at least two main shafts that are arranged in parallel, be respectively arranged with breaker roll on the main shaft, breaker roll is provided with some projectioies and depression, described projection and depression are along becoming distributed wave on the breaker roll axial direction, and projection on adjacent two breaker rolls and depression are coincide mutually and left the gap.

During the utility model work, two breaker roll contraries of coupling to or rotate in the same way, can adopt differential or constant speed rotation formula, pass gap between the breaker roll at the material above the breaker roll, through the gap time, material is extruded, tear fragmentation, because the projection on the breaker roll and caving in along becoming distributed wave on the breaker roll axial direction, effectively increased the contact area of broken material, 2 points that contact simultaneously with same material particles on the adjacent breaker roll, because its radius of gyration is inconsistent, its linear velocity is also inconsistent usually, consequently not only material can be pulverized, also material can be torn simultaneously, in the material shattering process, this effect of tearing accounts for main effect, reduced energy consumption so widely, simultaneously can reduce noise,, make the output of its broken material obviously improve owing to increased the plane of disruption of broken material, gap between adjacent two breaker rolls can be arranged to adjustable, to adapt to the fragmentation of variety classes material.Compared with prior art, the utility model noise is low, output is high, unit ton material power consumption is low, can be used for material grinding such as grain, feed.

As described in some convex ridges are set on projection and the concave face, can further increase the contact area of breaker roll and material, convex ridge can be strengthened the snap-in force to material, can promote the effect of tearing, and can further improve broken output.

But projection of the present utility model and depression toothing, trapezoidal, sinusoidal waveform, square waveform also can be that above-mentioned waveform combines, and breaker roll can be single parts, also can be the combination of a plurality of parts.

The specific embodiment

Embodiment 1

As Fig. 1-4, be a kind of kibbler roll, mainly comprise two main shafts 2 that are arranged in parallel, be respectively arranged with breaker roll 1 on the main shaft 2, breaker roll 1 is provided with the protruding 1b and the depression 1a of some toothing, described protruding 1b and depression 1a are along becoming distributed wave on the breaker roll axial direction, and protruding 1b on adjacent two breaker rolls and depression 1a coincide mutually and leave the gap; Described projection and concave face are provided with some convex ridges 4; Above-mentioned breaker roll is made up of some cutting dives 3 that are sleeved on the main shaft 2, described protruding 1b and depression 1a are consecutively arranged to form on major axes orientation by the outward flange that is profile of tooth on the cutting disc 3, cutting disc 3 can be scattered parts, shown in Fig. 2-4, so that local replacing; Also can be a plurality of even the formation cutting disc assembly that all is connected as a single entity, so that the adjustment of axial location.
