Description

Circular cone breaks grinding machine

The utility model relates to and a kind ofly is used for fine crushing, dry method grinding, wet grinding and to the broken grinding machine of circular cone of the swing crushing of various brittle materials.

The capital equipment that present China is used for fine crushing and meal mill has following weak point:

1), to be used for Mohs' hardness are double-roll crushers greater than the capital equipment of 6 stage material fine crushings, it comprises single pair roller and biconjugate roller, the ratio of reduction of single pair roller is little, the cost height of many pair rollers.Because grinding roller middle part quick abrasion is so the utilization rate of its grinding roller material is low.

2), the capital equipment that is used for meal mill is ball mill (comprise tube mill and air swept mill) and Raymond mill; Wherein ball mill efficiency is low, noise big, the metal abrasion loss is big; Raymond mill is not suitable for the grinding high hardness material, can not adopt wet grinding.

3), up till now for this reason, adopting the capital equipment of wet grinding still is that the lower stone of efficient is milled and ball mill.

The purpose of this utility model is the broken grinding machine of a kind of circular cone of developing at above deficiency, the material that it not only can the grinding high rigidity, but also can realize dry method continuous powder milling and wet method continuous powder milling.

The utility model is achieved in that the broken grinding machine of circular cone comprises the motor 1 of dress on the cover tube 2, cover tube 2 is contained on the body 13, body 13 is contained on the support 20, support 20 connects with frame 18 by shock-absorbing spring 17, wherein motor 1 connects with central shaft 4 by shaft coupling 3, central shaft 4 is inserted in the bearing cartridge 19, eccentric shoe 5, vibrator box 7 is sleeved on the central shaft 4, spring 6 is housed in the cavity of eccentric shoe 5, the left end of spring 6 withstands on the central shaft 4, oil sump 8 is contained in the upper end of bearing cartridge 19, the lower end of bearing cartridge 19 is contained on the bottom end cover 22, the import of radiator 12 connects by sebific duct 11 and oil sump 8, the port of export of radiator 12 connects by sebific duct 21 and bottom end cover 22, decides tapered sleeve 15 and is contained in the body 13, is pressed in the pressure ring of deciding on the tapered sleeve 15 14 and connects with body 13, mantle cover 16, lining 10 and nut 9 are sleeved on the bearing cartridge 19, and slide cartridge 24 is contained in the support 20.

The utility model can also be achieved in that on the central shaft 4 and be threaded.

The utility model also can be achieved in that eccentric shoe 5 be by about two form by Bolt Connection; Elastomer block 23 is housed in the slide cartridge 24.

Good effect of the present utility model is

1, because the utility model has adopted the pulverization principle of high-frequency impact shock, thus its can grinding Raymond mill, Vertical Mill, high pressure overhang roll mill and pulverizer can not grinding the material of high rigidity (greater than 6 grades of Mohs).

2, can process must be with the material of wet grinding to technological requirement for the utility model, and this mill and water pump, separator, conveyer (or elevator) is supporting both can realize the wet method continuous powder milling, but also higher by 23% than the efficient of ball mill.

3), the utility model and air blast, fineness separator, powder collector and the supporting use of deduster can realize the dry method continuous powder milling, under the power consumption situation identical with output, than the low cost of manufacture 35% of above-mentioned grinding machine (except the pulverizer).

4), the compression spring is housed in the vibrator of the present utility model, when excited frequency during greater than body intrinsic frequency several times, eccentric shoe compression spring strengthens exciting force and amplitude, and therefore this mill not only starts and be steady when shutting down, and it is little to start power consumption.

5), the utility model adopted hydrodynamic sliding bearing, is threaded on the central shaft, played the effect of screw oil pump, it both can provide sufficient lubricating oil to bearing, can make oil through filter and cooler again after recycling.This mill has solved that rolling bearing in cartridge type vibromill and other vibratory equipment is fragile, the problem of easy heating.
