Abstract

The utility model provides an energy-saving high-efficient ore mill, which comprises a milling barrel. The energy-saving high-efficient ore mill is characterized in that the milling barrel is provided with a gear, the gear is meshed with a driven gear, a gear shaft of the driven gear is provided with a driven wheel, the driven wheel is connected with a driving wheel on a spindle of a power driver through a transmission part, and an outlet end of the milling barrel is provided with a sieve. Torsion of a motor with low power can be enlarged by tens of times under two-stage reduction transmission, thereby meeting requirements of required force driving the milling barrel to rotate, simultaneously realizing speed reduction, and saving electricity more than 80%. The two-stage reduction transmission leads the structure of the ore mill to be simplified greatly, and then the ore mill is low in cost, convenient in maintenance and high in reliability. A conical sieve at a discharge end not only can lead fine ores under the sieve to be discharged smoothly during discharge, but also lead uncrushed coarse ores to automatically return into the milling barrel to be milled continuously, avoids repeated operation and has high work efficiency. By aid of the conical sieve, the energy-saving high-efficient ore mill does not need a huge spiral classifier, thereby saving equipment investment and maintenance cost without occupying space.

Description

A kind of energy-saving and high-efficiency ore grinding machine

Technical field

The utility model relates to a kind of ore mill, and particularly a kind of energy-saving and high-efficiency ore grinding machine belongs to mining machinery design and manufacturing technology field.

Background technology

In the stope, ore mill is a kind of important mines plant equipment, and it is responsible for the lump that exploitation is come out is ground, and makes the ore of big bulk become fine particle, so just can enter beneficiating process subsequently.Yet existing ore mill transmission adopts cylindrical gear reducer to drive the mill tube rotation, so bulky, cost is high, brings very big financial burden and construction investment to the user, brings a lot of inconvenience also for simultaneously maintenance and maintenance.In addition owing to adopt the cylindrical gear reducer transferring power, this just needs powerful motor to drive, thereby cause the ore dressing plant to electricity needs or require excessive, be unfavorable for energy savings, very power consumption in the use, the operating cost and the production cost in ore dressing plant have been increased, and because the problem of structure, the ore that does not grind during discharge also can together be discharged, again grind thereby have to the coarse grain mineral aggregate turned back in the grinding machine through spiral classifier, greatly increased grinding step and equipment investment, wasted time and energy.Therefore be necessary prior art is improved.

Summary of the invention

For solving existing ore mill complex structure, cost an arm and a leg, problems such as inconvenient maintenance and highly energy-consuming, the utility model provides a kind of energy-saving and high-efficiency ore grinding machine.

The utility model is finished by following technical proposal, a kind of energy-saving and high-efficiency ore grinding machine, comprise mill tube, it is characterized in that mill tube is provided with gear, this gear is meshed with driven gear, the wheel shaft of driven gear is provided with driven pulley, and driven pulley is connected with driving wheel on the power-driven machine main shaft by driving member, and the mill tube port of export is provided with sieve.So that under power-driven machine drives, rotate, thereby finish ore grinding by driving wheel, driven pulley, driven gear, gear driven mill tube.

The described wheel shaft two ends that driven gear and driven pulley are set on it are fixed on the frame by bearing and bearing block, so that fix this wheel shaft by bearing block, and make the wheel shaft rotation.

Driving wheel on described driven pulley and the power-driven machine main shaft is a belt pulley, perhaps sprocket wheel, and driving member therebetween is driving belt or driving-chain, wherein, the diameter of driving wheel and driven pulley ratio is: driving wheel: driven pulley=1: 2~3.

The diameter ratio of gear on the described mill tube and the driven gear that is meshed with it is: driven pulley: driving wheel=1: 20~22.

The hollow shaft at described mill tube two ends is socketed in respectively in the bearing on the bearing block, and bearing block is fixed on the underframe, so that by the bearing block fixed cylinder, and makes the cylindrical shell rotation.

The hollow axle end of described mill tube one end is a feed end, the hollow axle end of the other end is a discharge end, sieve at discharge end is made as the awl mouth interior, awl point conical screen outside, conical screen is arranged in the hollow shaft, and coaxial with mill tube, and with mill tube rotation together, good muck spills from sieve aperture so that make mill during discharge, and the ore that does not grind then automatically returns to and continues in the grinding machine to grind.

The utlity model has following advantage and effect: adopt such scheme, only need low power motor, just can be under the transmission of double reduction, make motor torsion increase tens of times, satisfied driving the required strength of mill tube rotation, realized simultaneously slowing down, economize on electricity reaches more than 80%, so just greatly reduced demand, saved electric power resource electric power.Simultaneously owing to only adopt the double reduction transmission, make mill structure simplify greatly, reduced the cost of purchasing and building, it is convenient to have brought to maintenance, the reliability of transmission device is improved, and owing to conical screen is set at exhaust end, not only when discharge, can allow the thin ore deposit under sieving discharge smoothly, continue in the mill tube to grind but also the raw ore that does not grind is returned automatically, avoid repetitive operation, saved the time, the man power and material, saved the setting of huge spiral classifier simultaneously by conical screen, saving equipment investment and maintenance cost, do not occupy the production space of limit, is a desirable energy-saving and high-efficiency ore grinding machine in fact.
