Abstract
The utility model relates to an eccentric mill for grinding minerals. The eccentric mill for grinding minerals comprises a spindle, an inner grinding ring and a grinding barrel, and is characterized in that the inner grinding ring is arranged on the spindle; an eccentric block is arranged above the spindle and is connected with the grinding ring through a bearing; and the grinding ring is in an eccentric structure relative to the grinding barrel. By using the eccentric mill, metal and non-metal minerals can be rapidly ground to the micron order by a dry method or a wet method. The eccentric mill can replace a ball mill and has the characteristics of energy saving and high efficiency.
Description
Technical field
The utility model relates to a kind of grinding mill, but fast-crushing metal and nonmetallic mineral to micron order, dry and wet way all can, alternative ball mill has the characteristics of efficient energy-saving.
Background technology
In existing mineral field of milling, domestic main employing ball mill, its maximum characteristics are bulky complex, and efficient is low, noise is large.But this just needs a kind of fast-crushing metal and nonmetallic mineral, can overcome the bias mill of all drawbacks of ball mill.
Summary of the invention
For achieving the above object, the technical solution adopted in the utility model is:
A kind of eccentric mill comprises main shaft, interior grinding ring, grinding drum, and interior grinding ring is contained on main shaft, feature is: an end of main shaft is equipped with belt pulley, eccentric block also is housed above main shaft, and eccentric block is connected with interior grinding ring by bearing, and the center of circle of main shaft is departed from the center of circle of interior grinding ring.
Described interior grinding ring is that single or multiple lift is arranged along major axes orientation, connects with rolling bearing or sliding bearing between interior grinding ring and eccentric block.Interior grinding ring and grinding drum adopt wear resistant alloy material.Interior grinding ring and grinding drum adopt potassium steel or rich chromium cast iron to be made.Bearing is sealed bearing.
The utility model has the advantages that: but the novel fast-crushing metal of this use and nonmetallic mineral to micron order, dry and wet way all can, can substitute ball mill and have the characteristics of efficient energy-saving.
Description of drawings
Fig. 1 is structural front view of the present utility model.
Fig. 2 is the cutaway view of A-A face of the present utility model.
In accompanying drawing: 1, grinding drum; 2, interior grinding ring; 3, bearing; 4, eccentric block; 5, main shaft; 6, belt pulley.
The specific embodiment
Be described further below in conjunction with 1～2 pair of the utility model of accompanying drawing:
Main body of the present utility model adopts vertical structure, has fixed grinding drum 1, interior grinding ring 2, eccentric block 4, bearing 3 and can drive the main shaft 5 that interior grinding ring 2 rotates.Grinding drum 1 is connected with frame.Interior grinding ring 2 can be integrative-structure, can be also that as shown in Figure 1 a plurality of rings from top to down are connected with eccentric block 4 by bearing.
The specific embodiment and operation principle:
The power of exterior motor drives main shaft 5 rotations by belt pulley, drive is fixed on eccentric block 4 rotations on main shaft 5, eccentric block 4 is connected with interior grinding ring 2 by bearing 3, interior grinding ring 2 rolls along the inwall of grinding drum 1 under the drive of eccentric block 4, material crush and grind between interior grinding ring 2 and bucket wall is become fine grained, complete process of lapping.For improving the service life of eccentric grinding machine, interior grinding ring 2 and grinding drum 1 adopt the wear resistant alloy materials such as potassium steel or rich chromium cast iron.The bearing 3 that connects eccentric block 4 and interior grinding ring 2 adopts the bearing with hermetically-sealed construction.
The utility model has the advantages that:
But the novel fast-crushing metal of this use and nonmetallic mineral be to micron order, dry and wet way all can, can substitute ball mill and have the characteristics of efficient energy-saving.
Embodiment recited above is described preferred embodiment of the present utility model; be not that design of the present utility model and protection domain are limited; under the prerequisite that does not break away from the utility model design concept; various modification and improvement that in this area, common engineers and technicians make the technical solution of the utility model all should fall into protection domain of the present utility model.
