Abstract

The utility model discloses a duplex hammer crusher, which comprises a crushing chamber (10) and a crushing hammering component (11) which is arranged inside the crushing chamber (10), wherein the upper side of the crushing chamber (10) is communicated with a feeding channel (30). The duplex hammer crusher also comprises a fine crushing chamber (20) and a fine crushing hammering component (21) which is arranged inside the fine crushing chamber (20), wherein the crushing chamber (10) and the fine crushing chamber (20) are communicated with each other through a charging channel (31). The duplex hammer crusher has the advantages that the duplex hammer crusher has the characteristic of high crushing efficiency and is favorable to reduce the investment scale of a production line due to realization of secondary crushing and fine crushing operations on the same hammer crusher, can greatly reduce the labor intensity of workers due to no necessity of labor or belts to convey and transfer materials, and can effectively reduce the flying dust and improve the quality of the production environment.

Description

The duplex hammer mill

Technical field

The utility model relates to disintegrating machine, particularly a kind of hammer mill.

Background technology

Hammer mill mainly is applicable at the broken medium-hard material of industrial departments such as cement, brickmaking, chemical industry, electric power, metallurgy, as operation broken and in small, broken bits in the materials such as lime stone, slag, coke, coal, shale, gangue.Existing hammer mill mainly is made up of crusher chamber and the parts such as hammering assembly that are installed in it, and the top of crusher chamber communicates with feeding-passage, and its underpart arc section is made of sieve plate.During work, the hammering assembly that has a plurality of tups by motor through reductor, transmission mechanism driven rotary, to enter material hammering fragmentation in the crusher chamber by feeding-passage, the material that reaches the regulation fineness drops out crusher chamber through sieve plate under gravity and/or compressed-air actuated effect.

For the brickmaking production line, since its shale, gangue raw material need through in multiple stage crushing operation such as broken, in small, broken bits just can reach fineness requirement, therefore usually to dispose the hammer mill of two and above quantity on the brickmaking production line, carry batch turning by artificial or belt between the upper and lower level hammer mill, this can cause the low and high deficiency of workman's operation intensity of crushing efficiency undoubtedly, and is unfavorable for reducing the scale of investment of production line.

The utility model content

Technical problem to be solved in the utility model provides a kind of duplex hammer mill, and it not only has the high characteristics of crushing efficiency, and helps reducing the scale of investment of production line.

The technical scheme that its technical problem that solves the utility model adopts is: duplex hammer mill of the present utility model, comprise crusher chamber and be installed on its interior broken hammering assembly, crusher chamber one side top communicates with feeding-passage, it is characterized in that: further comprising chamber in small, broken bits and be installed on its interior hammering assembly in small, broken bits, crusher chamber, chamber in small, broken bits are connected by material passing passage.

In technique scheme, described chamber in small, broken bits is positioned at non-charging one side of crusher chamber, and the direction of rotation of broken hammering assembly, hammering assembly in small, broken bits is opposite.

The beneficial effects of the utility model are that operation broken and in small, broken bits in realizing simultaneously on a hammer mill has the high characteristics of crushing efficiency, helps reducing the scale of investment of production line; Owing to no longer need artificial or belt conveying batch turning, therefore can reduce workman's operation intensity significantly, and can reduce airborne dust effectively, improve the production environment quality.

Description of drawings

This specification comprises as next width of cloth accompanying drawing:

Fig. 1 is the structural representation of the utility model duplex hammer mill.

Parts, toponym and pairing mark among the figure: crusher chamber 10, broken hammering assembly 11, sieve plate 12, chamber in small, broken bits 20, hammering assembly 21 in small, broken bits, sieve plate in small, broken bits 22, side sieve plate 23, feeding-passage 30, material passing passage 31.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

With reference to Fig. 1, duplex hammer mill of the present utility model, comprise crusher chamber 10 and be installed on its interior broken hammering assembly 11, crusher chamber 10 1 sides top communicates with feeding-passage 30, it also comprises chamber 20 in small, broken bits and is installed on its interior hammering assembly 21 in small, broken bits that crusher chamber 10, chamber in small, broken bits 20 are connected by material passing passage 31.The material that does not reach the regulation fineness in the crusher chamber 10 enters chamber 20 in small, broken bits under the effect of compressed air, proceed the hammering fragmentation by hammering assembly 21 in small, broken bits, till material reaches the regulation fineness.Therefore, operation broken and in small, broken bits during the utility model can be realized on a hammer mill simultaneously has the high characteristics of crushing efficiency, helps reducing the scale of investment of production line; Since no longer need artificial or belt conveying batch turning, workman's operation intensity can be reduced significantly, and can reduce airborne dust effectively, improve the production environment quality.

Shown in Fig. 1 is a kind of preferred disposition form of the present utility model.With reference to this figure, described chamber 20 in small, broken bits is positioned at non-charging one side of crusher chamber 10, and the direction of rotation of broken hammering assembly 11, hammering assembly 21 in small, broken bits is opposite.The bottom arc section of described crusher chamber 10 is made of sieve plate 12, and the bottom arc section in chamber 20 in small, broken bits is made of sieve plate 22 in small, broken bits.For improving the discharging efficient in chamber 20 in small, broken bits, described chamber 20 in small, broken bits and material passing passage 31 right sidewall arc section constitute by side sieve plate 23, this side sieve plate 23 is laid in hammering assembly 21 rotary main shafts in small, broken bits above water.Usually, the sieve diameter of described sieve plate 12, sieve plate in small, broken bits 22, side sieve plate 23 is identical.During crushing operation, material such as shale, gangue is entered in the crusher chamber 10 by feeding-passage 30, broken hammering assembly 11 carries out the hammering fragmentation to it, the material that reaches the regulation fineness drops out crusher chamber 10 12 times through sieve plate, and the material that does not reach the regulation fineness enters chamber 20 in small, broken bits under the effect of compressed air, proceed the hammering fragmentation by hammering assembly 21 in small, broken bits, reach the regulation fineness and till sieve plate 12 in small, broken bits, side sieve plate 23 falls or blown out chamber 20 in small, broken bits by air-flow until material.

Some principles of the above the utility model duplex hammer mill that just explains through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
