Description
Technical field
The utility model relates to a kind of flour mill, particularly relates to a kind of Multi-roll fine flour mill.
Background technology
Other roll mill pulverizers such as existing vertical roll grinder, Raymond mill in current grinding industry, all make crushing material by the extruding of grinding roller and liner plate (lining ring), its structure is all that grinding roller is arranged on fixing axle, by bearing, grinding roller is rotated and is equipped with the pressuring method such as hydraulic pressure or spring.Complex structure, trouble point is many, and effect is unsatisfactory, and maintenance handling trouble is time-consuming, and bearing seal problem is difficult to solve, and makes operation rate low.Because the size of grinding chamber grinding roller and liner plate (lining ring) is limited, material time of staying in grinding machine is short, and material is few by the number of times rolled, disposable low by powder formation rate after grinding machine, material will reach fineness requirement repeatedly should return mill again, therefore grinding machine production efficiency is low.Grinding roller and liner plate high-speed friction repeatedly in operation process, makes body temperature rise too high, easily makes workpiece anneal or bearing burns ring.
Utility model content
Technical problem to be solved in the utility model is to provide a kind ofly once passes through into the multiple roll flour mill that mealiness is high, running rate is high and energy-conservation.
For solving the problems of the technologies described above, the multiple roll flour mill that the utility model provides, comprise bearing block, body, discharge bucket, main shaft, feed pipe and cooling system, the described main shaft be in described body is provided with the rotor disk that spreading disk and at least two layers are in the below of described spreading disk, described body is provided with the wear-resisting lining ring coordinating with described rotor disk and grind, the circumference of the rotor disk described in every layer is evenly equipped with at least 2 Wearing-resistant rollers, and described Wearing-resistant roller is in described rotor disk and described wear-resisting lining ring.
Described body is Hough edge opener body.
The quantity of described Wearing-resistant roller is 4 ~ 10.
Described cooling system is the cooling jacket be located on described body, the delivery port be connected with described cooling jacket and water inlet.
Described delivery port is connected with the upper end of described cooling jacket, and described water inlet is connected with the lower end of described cooling jacket.
Described rotor disk circumference is evenly provided with at least 2 " U " v notch vs, and described Wearing-resistant roller is arranged in described " U " v notch v.
Described Wearing-resistant roller is three pitch cylinder Wearing-resistant rollers, described " U " v notch v staggered floor on the direction of the upper bottom of described rotor disk is arranged, the upper lower bearing pin portion of three pitch cylinder Wearing-resistant rollers described in installing in the gap portions of described " U " v notch v, three described pitch cylinder Wearing-resistant rollers contact as the whole position of liner with described wear-resisting lining ring.
Described Wearing-resistant roller is cavity ring roller, and described cavity ring roller rotates in " U " v notch v described in installing.
Adopt the multiple roll mill of technique scheme, motor drives main shaft to rotate by belt pulley, and spreading disk the kinetic energy of rotation passed to by main shaft and rotor disk rotates.Symmetrical uniform 4 ~ 10 Wearing-resistant rollers on every layer of rotor disk, N layer altogether, wear-resisting lining ring is installed in body, under main shaft rotation status, Wearing-resistant roller is outwards dished out by centrifugal action, Wearing-resistant roller is close to wear-resisting lining ring and is rolled, both rotation was also revolved round the sun, because the multiple Wearing-resistant roller of multilayer defines a centrifugal force field, can be rolled until powder carefully goes out mill by repeated multiple times after material enters mill, like this when even feeding, can make to form one deck between Wearing-resistant roller and wear-resisting lining ring material bed, and Wearing-resistant roller can not be made directly to grind on wear-resisting lining ring face, the loading of material in mill is controlled by the size of feeding quantity, thus do not make material cross grinding, final high point is reached to make grinding efficiency, to requiring the particularly important selection of the product of superfine powder.
In the technical program, because Wearing-resistant roller is in relative freely-movable state all the time, in the course of work, existing impulsive force is milled again pressure under the action of the centrifugal, material is forced broken, be specially adapted to medium-hard material, the pulverizing processing of fineness in 38 μm.Its body adopts Hough to open the structure on limit, novel structure, easy to loading and unloading, can effectively damping.There is cooling jacket at engine body exterior, the temperature rise in grinding process can be effectively reduced, thus protect bearing and wearing piece, extend its service life.
This machine efficiency is high, and go out all neat operating mode of grind materials particle good, reduced investment easy to maintenance, only has the consumptive material 1/3 of conventional roller-type grinding machine in equal milling capacity situation; The power consumption less than 50% of conventional roller-type grinding machine.Full-enclosed structure, raise without outside dust, floor space is few, only have 1/5 of same output conventional roll grinding machine, can substitute the conventional roller-type grinding machine in fine break completely, also can form separately open circuit or closed loop system work, be a kind of strong adaptability, the novel multiple roll flour mill that handsome in appearance, novel structure, fault are few, efficiency is high.
In sum, the utility model is a kind of multiple roll mill being applicable to medium hardness material grinding, its structure is simple, practical, cost is low, energy-conservation, consumption reduction, easy to maintenance, environmental protection, operating mode are good, be specially adapted to Mohs' hardness less than 8 grades in the industries such as building materials metallurgy, chemical industry, mine, the energy, electric power, refractory material, finish fineness is not higher than the dry method grinding of the various materials of 38 μm.
