When (when the Protodyakonov coefficient f > 10 of material) continuous milling machine cutting teeth cutting it is difficult or can not cut, when cutting, required roller is turned round
Square will increase, and give equipment belt larger pressure, be easy to cause equipment damage, this just significantly limits the use model of continuous milling machine
It encloses；Furthermore some ores such as gold ore, existing production technology are that the ore of missile silo work exploitation extraction transports to enrichment plant, mine
Shi Xianjing is broken together, and crusher is alligator, and outlet grain size is Φ≤25mm, is crushed, is exported with ball mill for the second time
Granularity Wei Φ≤25mm；Gold ore need to be produced through multiple working procedure, and high production cost, production efficiency are low；In addition, existing continuous milling machine
Cutting teeth involves great expense, once damaging, and replaces, maintenance difficult, and maintenance cost is high, influences production efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of grinding wheel flour milling continuous milling machines, when hardness Protodyakonov coefficient f > 10 of ore
When, the cutting teeth cutting of existing continuous milling machine is difficult or can not cut, at this moment using grinding wheel matter abrading block by ore in powder form from
Under being ground on rock mass；The pressure that the pressure ratio as needed for ore grinding cuts ore is much smaller, and cutting force is also more much smaller than cutting ore, institute
The roller torque needed is more much smaller than existing continuous milling machine cutting drum, and equipment is just hardly damaged, and extends service life；Meanwhile
Directly just ore can be crushed in mining phase by ore grind into powder, such as when exploiting gold ore when ore dressing
Processing eliminates subsequent crusher broken process, and provides convenience for ball mill crushing；Furthermore grinding wheel matter abrading block cost phase
To lower, and dismountable mounting structure is used, once damage, can fast, easily replace local damaged location, mention
High efficiency.
The technical solution adopted in the utility model is as follows: a kind of grinding wheel flour milling continuous milling machine, it is characterised in that: continuous milling machine
Roller includes roller parent, grinding wheel matter abrading block, metal frame, cutting drum main shaft；The roller parent uses existing cutting drum
Shape；Roller parent cylindrical surface is distributed the metal cage to concave in one week；The grinding wheel matter abrading block is mounted on metal
It on frame, then is rigidly mounted together in metal cage together with metal frame, after installing, grinding wheel matter abrading block is covered with roller parent circle
Cylinder one week, and grinding wheel matter abrading block top surface is higher than roller parent cylindrical surface；The roller parent is mounted on cutting drum main shaft,
It is rotated under the drive of cutting drum main shaft, the grinding wheel flour milling be made of under radial force effect grinding wheel matter abrading block and ore body friction
Ore is exploited with powdered.
Preferably, the metal cage, grinding wheel matter abrading block, metal frame shape be inverted fang platform body.
It preferably, is dismountable connection structure between the metal cage, grinding wheel matter abrading block, metal frame three.
Preferably, the metal cage, grinding wheel matter abrading block, the connection parallel with cutting drum main shaft is set in metal frame
Grinding wheel matter abrading block, metal frame are removably attached in metal cage by hole by connecting rod.
Preferably, at least two roller with grinding wheel flour milling of continuous milling machine installation.
The utility model has the beneficial effects that: the grinding wheel flour milling continuous milling machine can be hard with digging compared with existing continuous milling machine
The ore body for spending (f>10), increases the use scope of continuous milling machine, such continuous milling machine is no longer the dedicated continuous milling machine of coal mine (f<4)
And become the continuous milling machine that can exploit of all mineral, the ore of extraction be it is powdered, provide convenience for next step ore dressing.
Further, as the hardness Protodyakonov coefficient f > 10 of ore, the cutting teeth cutting of existing continuous milling machine is difficult or can not cut
It cuts, under at this moment being ground ore from rock mass in powder form using grinding wheel matter abrading block；The pressure ratio as needed for ore grinding cuts ore
Pressure it is much smaller, cutting force also than cutting ore it is much smaller, required roller torque is smaller than existing continuous milling machine cutting drum
Much, equipment is just hardly damaged, and extends service life；Meanwhile it can be by ore grind into powder, such as in exploitation gold when ore dressing
When ore, ore has just directly been subjected to break process in mining phase, has eliminated subsequent crusher broken process, and has been ball milling
Machine crushing is provided convenience；Furthermore grinding wheel matter abrading block cost is relatively low, and uses dismountable mounting structure, once damage,
Fast, easily local damaged location can be replaced, improve production efficiency.
