Description
Technical field
The utility model is related to a kind of impact grinding mill, coal comminution dissociates especially a kind of gravity treatment suitable for coal preparation plant
Quick washing grinding mill.
Background technology
It is the important technical realized coal (including middle coal) and efficiently dissociated to be crushed and grind.For coal in gravity treatment
Speech it may first have to which centering coal, which carries out depth crushing, can just be such that bastard coal fully dissociates, but be not broken more thinner better.Because with
The reduction of granularity, sorting difficulty is bigger, and sorting cost is also higher.Especially need to adopt when material size reaches 0.5mm or less
When being detached with floatation, it will dramatically increase coal separation cost.It therefore, should be as far as possible in coarse grain condition from the angle of Technological Economy
The lower efficient dissociation for realizing coal avoids crushed product from crossing crushing that is, while ensureing that bastard coal fully dissociates.Therefore, it designs
Development set is impacted and is milled in the efficient comminution dissociation apparatus of middle coal of one, solves existing coal crushing equipment particle size after cracking lower limit
Height, the broken dissociation effect of middle coal is poor, and crusher chamber easily blocks and coal-grinding device product dissociation effect is good, but it is tight to cross crushing phenomenon
Weight, the problem that follow-up separation is difficult and processing cost is high can be the recycling of cleaned coal after the efficient dissociation of coal in coal preparation plant's gravity treatment and dissociation
It creates favorable conditions.
Invention content
Technical problem：The purpose of this utility model be aiming at the deficiencies in the prior art, provide it is a kind of it is simple in structure,
Comminution granularity lower limit is low, crushing phenomenon is small excessively, be not easy to plug, the quick washing that broken rear middle product of coal dissociation effect is good is milled
Machine.
Technical solution：The quick washing grinding mill of the utility model, including pedestal, the cartridge type body that is located in mounting seat
And band transmission, the inner wall of the cartridge type body are equipped with counterattack block, the bottom of cartridge type body quickly goes out equipped with open type
Material mouth, cartridge type body are internally provided with comminution roller, and the top of cartridge type body is equipped with feed inlet, and the comminution roller is through shaft coupling
It is connected with band transmission, the roll shaft of comminution roller is more prismatic roll shafts, and more prismatic roll shafts are equipped with and are transported at arc track
Capable multiple arcs comminution impact block, the central axes of comminution roller are less than the central axes of cartridge type body.
The arc comminution impact block includes fixed impact block and the saw that is connected with fixed impact block through high-strength bolt
Flute profile impact block.
The gap between counterattack block in the arc comminution impact block and cylinder machine body on wall is opened by feed inlet to bottom
Open type quickly discharging mouth gradually reduces.
More prismatic roll shafts of the comminution roller are 6 prismatics or 8 prismatics.
Comminution roller central axes are 20-40mm less than the distance of cartridge type body central axes.
Advantageous effect：By adopting the above-described technical solution, the central axes of the utility model comminution roller are less than cylinder machine
The central axes of body, comminution roller are equipped with arc comminution impact block, in arc comminution impact block and cylinder machine body between wall counterattack block
Gap gradually reduced by feed inlet to bottom-open formula quickly discharging mouth, into coal in the gravity treatment in crusher chamber body with impact
It power and mills under force effect, is efficiently dissociated, and the open type quickly discharging mouth being equipped with via cartridge type organism bottom is arranged in time
Go out that cylinder machine is external, can effectively avoid the blocking of crusher chamber.Compared with prior art, the quick washing grinding mill of the utility model
Simple in structure, comminution granularity lower limit is low, and crushing phenomenon excessively is small, is not easy to plug, middle product of coal dissociation effect is good after comminution, is conducive to
The recycling for realizing cleaned coal in centering coal can effectively solve limit for height under existing coal crushing equipment particle size after cracking, the broken dissociation of middle coal
Effect is poor, product cross crushing phenomenon serious, follow-up separation and place after the susceptible to plugging problem of crusher chamber and existing coal-grinding equipment mill
Manage problem of high cost.
Description of the drawings
