Description

Vibrating grinding machines with features of high efficiency

The present invention relates to a kind of improved vibrating mill, particularly a kind of energy is fit to the equipment of large, medium and small type powder technology, can be used for metallurgy, building materials, chemical industry, emery wheel material, each different field such as refractory material, glass.

Existing vibrating mill is mainly by mill tube, wear-resisting lining, vibrator, shaft coupling, metal coil spring, spring fastening, motor, abrasive media, the ball-handling grate plate, compositions such as the soft connection of input and output material, existing vibromill mill tube mostly is three most both at home and abroad, two tube mills are arranged in normal employing up and down, also produced in small quantities one tube mill, all vibrating mills are the single motor of vibrator and drag, 1000 liters of bitubulars of the maximum appearance machine of the vibrating mill of domestic production at present, external 2200 liters of bitubular grinding machines of maximum volume, its maximum throughput does not surpass 12l/h, be mainly used in ultra-fine mill operation, and can't be widely used in metallurgy, industries such as building materials.

Task of the present invention is that a kind of improved vibrating mill will be provided, because its disposal ability is big, efficient height, energy consumption are low, thereby can be widely used for many industries such as metallurgy, building materials.

Task of the present invention is finished as follows: adopt many mill tubes, minor diameter is situated between interior all mills of mill tube can both obtain than macro-energy bi-motor, two cover vibrator work, big vibration acceleration, all mill tube parallel operations, for grinding machine is effectively worked, divide one or two to three Room in each mill tube.Be separated by with dividing plate between every chamber, the length feeding end of two Room is 1: 4 to the ratio of discharging, and three Room are 1: 2: 2.Mill Jie is cylinder in each chamber, its diameter reduces successively from feeding end to discharging, and its length usually adopts one to two Room system work than short 30～40 millimeters of corresponding mill chamber, when carrying out ultra-fine mill operation, the normal three Room systems that adopt are filled elongated cylinder in preceding two Room, the short steel section in one Room, back, between short steel section chamber and discharge gate, separate in order to avoid the steel section is discharged from discharge gate with grate plate, convenient in order to change mill tube, wear-resisting lining connects with flange with body one end, and an end is solid with the flange banding.After grinding away, bolt pine on the flange can be gone mill tube, from newly replacing with new mill tube, bi-motor drags four vibrator work, in order to make the grinding machine body obtain more satisfactory round translation track, thereby be provided with the forced synchronism gear-box, motor output shaft connects with the power shaft of gear-box respectively, two output shafts of gear-box link with vibrator respectively, link with Hooke's joint between vibrator and gear-box, body is bearing on the spring, in order to utilize mill tube fully volume is arranged, in a Room or two Room when work, take down discharge gate end grate plate, strengthen nesting population size, make mill tube working size lengthening.Vibrator is rotation at a high speed under motor-driven, like this, vibrator has just produced periodically forced vibration power to body, thereby body has obtained to be similar to round elliptical trajectory, each mill tube medium has just obtained three kinds of motions, respectively material is played a different role, it is strong projectile motion, rise the bulk materials fragmentation, two is the high speed rotation, plays abrasive action, three are revolution at a slow speed, play the homogeneous material effect, material is discharged with spiral motion orbiting motion to discharge gate from feed end, thereby has finished grinding process.

The present invention is described in further detail below with reference to accompanying drawing.

Operation principle:

This grinder body can be thought the single-degree-of-freedom forced vibration with damp approx, the vibrator eccentric mass under motor-driven with certain frequency High Rotation Speed. Like this, vibrator has just produced periodically forced vibration power to body, thereby body obtained to be similar to round elliptical trajectory, and each mill tube medium just obtains three kinds of motions, that is:

1. strong impelling, bulk materials is rapidly broken;

2. at a high speed in the same way rotation plays abrasive action;

3. at a slow speed revolution plays the homogeneous material effect.

Material is constantly discharged with spiral motion orbiting motion to discharge gate from the continuous crushing grinding of feeding end, thereby has finished grinding process.
