The energy-saving and environment-friendly rolling stone roller of one kind makes sand machine
The invention belongs to roll stone roller apparatus field, specifically provides the energy-saving and environment-friendly rolling stone roller of one kind and make sand machine.
Sandstone is indispensable a kind of construction material in architectural engineering.With the fast development of building trade, it is traditional from
Supply falls short of demand for right river sand, and artificial sand steps into market.The sand equipment of making of drum-type mostly uses greatly ball mill and rod milling at present
Machine is added milling mediums, the milling mediums such as rod iron, steel ball that is, in the cylinder of rotation and is brought to the rotation of cylinder centainly
Height after leave from top to bottom, by ore reduction.But these equipment are all the endfeed from cylinder mostly, from the another of cylinder
One end discharge, i.e., unilateral charging, processing efficiency is low, and discharge has some setbacks, is easy to happen clogging.Material size after grinding
Unevenness is still needed to connect screening plant and be sieved, energy consumption is high if you need to segment.
Summary of the invention
The purpose of the present invention is overcoming drawbacks described above, the energy-saving and environment-friendly rolling stone roller of one kind is provided and makes sand machine.
Technical solution of the present invention: the energy-saving and environment-friendly rolling stone roller of one kind makes sand machine, including rack, cylinder and driving device, institute
It states and is equipped with liner plate in cylinder and medium is ground in rolling, cylinder both ends are equipped with charging bucket, clearance hole are equipped in the middle part of cylinder, outside cylinder
Equipped with sieve, the sieve is connected along the setting of cylinder circumference, both ends open, and by connecting column with cylinder.
Material is fed from cylinder both ends bucket, the clearance hole row after the rolling that medium is ground in rolling is ground, crushed in the middle part of cylinder
Out；Again by further being sieved under the action of sieve.Sieve can be positioned below hopper or conveyer belt, will screen out the fines come and receives
Collection, transmission.Coarseer material is discharged to feed well from screen end, re-starts rolling and grinds screening.
Two endfeeds are equivalent to two machines being combined into one, substantially increase processing efficiency, and material discharge is more smooth,
It is not susceptible to clogging.
Preferably, it is equipped with L-type striker plate in the charging bucket, the material for not entering into cylinder on a small quantity can be blocked,
It prevents from leaking out, the cylinder of the charging bucket and cylinder junction is equipped with feed inlet.It is fed using bucket, and directly in cylinder
Both ends side wall upper opening is directly fed, and structure is simpler, and charging is more smooth, and further increases powder feeding efficiency.
Preferably, the charging bucket quantity at cylinder both ends is identical, can be set as 1-6 according to instrument size, and both ends into
Material bucket is uniform staggered with along cylinder circumferencial direction, can reduce the eccentric caused impact of cylinder, equipment is made to run smoothly.
Preferably, feed well is equipped with below the cylinder of the charging bucket position.It can be not only used for feeding, also collect screening
The biggish material of particle out, waiting are fed next time, are realized to grind from closed circuit rolling and be sieved.
Preferably, the sieve is in low skewed in intermediate high, both ends.The sieve being obliquely installed can efficiently use gravity work
With, by the material screening compared with fine grain and discharge, and the material of greater particle size is discharged by screen end, and returns to feed well, into
Screening is ground in the rolling of row next round, had both been realized to grind from closed circuit rolling and sieved.
Preferably, the sieve includes the second sieve in the middle part of the first sieve and separate cylinder in the middle part of cylinder, the
Aperture of the aperture of one sieve less than the second sieve.It is equipped with fines feed bin below first sieve, is equipped with below the second sieve
Coarse fodder hopper.Material is subjected to screening collection by different-grain diameter grade, the material of different-grain diameter needed for obtaining.
Preferably, the driving device includes being located at thef first bearing section and the second bearing portion at cylinder both ends, described
Second bearing portion is successively connected with first shaft coupling, speed reducer, second shaft coupling and motor.Replaced using center driving common
The big pinion gear peripheral-traction of grinding machine, it is compact-sized, occupied ground is small.Bearing uses roller bearing, is further reduced system energy consumption.
Preferably, outer framework is additionally provided with outside the cylinder and driving device.The outer framework uses acoustic material, will set
It is standby to surround, effective noise reduction function pollution.
Preferably, it is rod iron that medium is ground in the rolling.The cylinder that rod iron is rotated takes eminence to, then under the effect of gravity
It scrolls down through and slides along liner plate, material rolling is ground into fine particle, the sand produced is close to natural river sand.
The invention has the advantages that 1, two endfeeds, middle part discharging, substantially increase processing efficiency；And material discharge is more smooth, no
Easy blockage phenomenon can avoid qualified material and operate in equipment for a long time, reduce equipment energy consumption, improves continuous production.
2, fed using bucket, and directly cylinder both ends side wall upper opening feed, structure is simpler, feed it is more convenient,
It is smooth, powder feeding efficiency is improved, the processing efficiency of equipment is improved.
3, sieve is installed outside cylinder, rolling is ground and is carried out simultaneously with screening, reduces equipment investment；The material that rolling is ground out
Gradation sizing is carried out, the material of larger particles returns to feed well, realizes from closed cycle, improves the automatic capability of equipment.
4, rolling grinds medium and is brought to after certain height and tumbles from top to bottom along shell liner with the rotation of cylinder
And slide, drum speed decreases relative to ball mill and rod mill, to save more power, energy-saving effect is obvious.
