Abstract
The utility model relates to a crushing system. The crushing system comprises a hammer crusher and a fan, wherein grate bars are arranged inside the hammer crusher and divided into two parts which are connected with each other along the vertical plane of the center of a rolling shaft of the hammer crusher, namely a first grate bar combination and a second grate bar combination respectively, the first grate bar combination is in linear arrangement or linear and arc-shaped arrangement, the second grate bar combination is in arc-shaped arrangement, the distance between the grate bars in the first grate bar combination and the second grate bar combination is 1-30mm, the minimum interval between the first grate bar combination and a hammer head of the hammer crusher is greater than or equal to 2mm, a blow-off nozzle is formed in the hammer crusher and positioned above the first grate bar combination, the distance between the extension line of the blow-off nozzle and the grate bars in linear arrangement is 0-20mm, and the blow-off nozzle is connected with the fan through an air bellow. The crushing system can well adapt to the crushing of medium-soft materials with complicated material hardness composition and water content being above 8%, and is high in economical efficiency; and the crushing system can realize economical crushing of low-grade minerals to fully utilize resources.
Description
Technical field
The utility model relates to a kind of crushing system.
Background technology
Broken material generally makes material cracked with extruding, strike, collision mode, realizes broken purpose.Crushing efficiency is influenced by hardness, proportion, moisture of material itself etc.
The deficiency that most popular hammer mill exists in the existing disintegrating apparatus is, when the mineral that contain the different hardness complicated component are carried out break process, be difficult to continuous firing effectively, can not realize the broken production of economy, reason is, by crushed material easily and water function stick to the inside cavity of disintegrating apparatus, especially easily be deposited in discharging opening, cause discharging opening to stop up, and then abrasion damages disintegrating apparatus, reduce broken production capacity and efficient, shorten disintegrating apparatus greatly and effectively work the duration of runs.
For example, broken moisture is greater than 8% material, and discharging opening is very easily blocked, and disintegrating apparatus is difficult to the work of turning round continuously, can not realize that economy is broken and produces, and when serious, can only stop broken production.
For complicated component, low-grade mineral that water content is high, as adopt existing disintegrating apparatus and technology, owing to can't realize the economy fragmentation, and be forced to abandon, both contaminated environment caused the great wasting of resources again.The iron ore deposit total amount of China is very big, and wherein complicated component, low-grade poor iron ore that water content is high account for greatly, if these resources can be made full use of, just can obtain huge economic interests.
The utility model content
Technical problem to be solved in the utility model is, provides a kind of applied widely, and continuous firing can realize the broken crushing system of producing of economy effectively.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of crushing system, comprise hammer mill, the inside of described hammer mill is provided with the grate bar, also be provided with blower fan, described grate bar is divided into continuous two parts along place, hammer mill roller bearing center of circle vertical plane, be respectively the combination of the first grate bar, the combination of the second grate bar, described first grate bar combination is arranged in a linear or linearly adds arc shooting, the described second grate bar makes up curved arrangement, described first grate bar combination, distance in the combination of the second grate bar between grate bar and the grate bar is 1-30mm (preferred 18-22mm), the minimum interval 〉=2mm of the tup of described first grate bar combination and hammer mill; Described hammer mill is provided with blowing mouth, and described blowing mouth is positioned at the top of first grate bar combination, and the distance of the extended line of described blowing mouth and grate bar arranged in a straight line is the preferred 2-8mm of 0-20mm(), described blowing mouth links to each other with blower fan by bellows and pipeline.
Further, described blowing mouth is 50-100 (preferred 60-80), and the distance between adjacent two blowing mouths is the preferred 3-5mm of 2-10mm(), the blowing mouth diameter is the preferred 8-10mm of 2-12mm().
Further, the outer end of described second grate bar combination is provided with auxiliary discharge gate.
During work, start hammer mill and blower fan earlier, put into then and treat broken material, material is broken back gained powder under the wind-force effect, can not stick on the grate bar, cause discharging opening to stop up, and can discharge yet through auxiliary discharge gate for the bigger material of some particles.
Compared with prior art, the utlity model has following advantage: can be adapted to the soft material fragmentation in more than 8% of material hardness components complexity, water content well, the economy height; Can make low-grade mineral mineral realize the economy fragmentation, resource is fully used; Simultaneously, even rainwater unbroken season also can carry out ordinary production.Can also make the left slag of old mine, slag realize that fine crushing is handled recovery in the economy, discarded object is turned waste into wealth, be beneficial to environmental reconstruction and improvement; For the water content height, contain abrasion material, the fragmentation of soft complicated ingredient material such as quartz and provide economy broken solution.
Description of drawings
Fig. 1 is the structural representation of existing hammer mill;
Fig. 2 is the structural representation of the utility model crushing system embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
With reference to Fig. 2, present embodiment comprises hammer mill 1 and blower fan 2, the inside of described hammer mill 1 is provided with the grate bar, described grate bar is divided into continuous two parts along place, hammer mill roller bearing center of circle vertical plane, be respectively first grate bar combination, 3, second grate bar combination 4, described first grate bar combination 3 linearly adds arc shooting, the described second grate bar makes up 4 curved arrangements, distance in the combination 4 of described first grate bar combination, 3, the second grate bar between grate bar and the grate bar is 20mm, and described first grate bar combination 3 is 10mm with the minimum interval of the tup of hammer mill; Described hammer mill 1 is provided with blowing mouth 5, and described blowing mouth 5 is positioned at the top of first grate bar combination 3, and its extended line is 6mm with the distance of grate bar arranged in a straight line, and described blowing mouth 5 passes through bellows 6 and pipeline links to each other with blower fan 2.
Described blowing mouth 5 is 70, and the distance between adjacent two blowing mouths is 4mm, and the blowing mouth diameter is 10mm, and the outer end of described second grate bar combination 4 is provided with auxiliary discharge gate 7.
During work, start hammer mill 1 and blower fan 2 earlier, put into then and treat broken material, material is broken back gained powder under wind-force (blast is 20kPa) effect, can not stick on the grate bar, cause discharging opening to stop up, and can discharge yet through auxiliary discharge gate for the bigger material of some particles.
(with reference to Fig. 1) compares with prior art, and present embodiment accommodation is wider, and continuous firing can realize the broken production of economy effectively, can be adapted to the soft material fragmentation in more than 8% of material hardness components complexity, water content well, the economy height; Can make the fragmentation of low-grade mineral mineral economic, resource is made full use of, also for the water content height, contain abrasion material, the fragmentation of soft complicated ingredient material such as quartz and provide economy broken solution.
