Abstract
The utility model discloses an autogenous tumbling mill complex discharge barrel comprising a discharge barrel body which consists of a discharge barrel shell of a carbon steel material, and a wear rubber material wear proof layer which covers on the inner surface of the discharge barrel shell. The utility model solves the problems of iron chips produced by the abrasion of quartz sand and the discharge barrel which increases the content of iron in quartz sand products, and thereby improves the quality of the quartz sand products.
Description
Technical field
The utility model relates to a kind of technical field of autogenous tumbling mill, especially relates to a kind of composite discharge barrel of automatic mill that is used on the autogenous tumbling mill.
Background technology
Autogenous tumbling mill is as a kind of run-of-mine-milling equipment that relies on material self to impact mutually, grind and pulverize, and having need not medium, feeding granularity scope big (can reach 600mm), the output height, advantages such as discharge is even in the ore in sand form processing industry, have obtained in the processing as quartz sand using very widely.But the applied autogenous tumbling mill of current people, it is some ferrous materials that the material that parts adopted on it mostly is, as the discharge barrel made from ductile cast iron material, discharge barrel is the parts that wearing and tearing are only second to mill tube and weight maximum on the autogenous tumbling mill, thereby it not only makes autogenous tumbling mill have bigger deadweight to cause the autogenous tumbling mill drive unit to have big working strength and live load, and adopt the discharge barrel made from ductile cast iron material when quartz sand being processed processing, can and cause wearing and tearing with the frequent generation friction of quartz sand particle, and the generation iron filings are incorporated in the middle of the quartz sand product of being processed, the quartz sand product is polluted, iron-holder in the quartz sand product is increased greatly, influenced the quality of quartz sand product.And the quartz sand product requires than higher iron-holder, and this just need adopt other operation and method to remove these iron filings in the quartz sand product again, and this has increased the quartz sand production cost of products to a certain extent, has reduced production efficiency.
Summary of the invention
The technical problems to be solved in the utility model has provided a kind of composite discharge barrel of automatic mill, it has avoided discharge barrel to cause the problem that iron-holder increases in the quartz sand product because of producing iron filings with the quartz sand particle wearing and tearing, improve the quality of product, reduced production cost of products.
For solving the problems of the technologies described above, the technical solution of the utility model is: composite discharge barrel of automatic mill, comprise the discharge barrel body, and described discharge barrel body comprises the discharge barrel housing, the inner surface of discharge barrel housing is coated with wear-resistant protective layer.
As a kind of improvement, described wear-resistant protective layer is the abrasive rubber layer.
As further improvement, described abrasive rubber layer and discharge barrel housing bonding are fixing.
As further improvement, described discharge barrel housing is a carbon steel discharge barrel housing.
Adopt the composite discharge barrel of automatic mill of said structure; constitute a kind of discharge barrel of composite bush formula by the mode that adopts the wear-resistant protective layer that covers by the discharge barrel housing with at the inner surface of discharge barrel housing; solution enters the problem that the quartz sand product pollutes at the frequent iron filings that friction and friction produced of quartz sand process quartz sand particle and discharge barrel; reduced the difficulty of removing the iron that is contained in the quartz sand product in the subsequent handling; improve the quality of quartz sand product, reduced the quartz sand production cost of products.By adopting the discharge barrel housing of abrasive rubber layer and carbon steel material, not only make this composite discharge barrel have enough working strengths, also guaranteed the service life of composite discharge barrel, also reduced the weight of discharge barrel simultaneously, reduced production cost, made things convenient for the use of people discharge barrel.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described:
Fig. 1 is the structural representation of composite discharge barrel of automatic mill of the present utility model;
Fig. 2 be among Fig. 1 A---A to cutaway view.
The specific embodiment
See figures.1.and.2; a kind of composite discharge barrel of automatic mill of the present utility model is: comprise discharge barrel body 1; this discharge barrel body 1 comprises discharge barrel housing 11; thereby the inner surface at discharge barrel housing 11 is coated with the discharge barrel that wear-resistant protective layer 12 constitutes a kind of composite bush formula; in order both to guarantee the intensity of this composite discharge barrel; guarantee the service life and the effect of this composite discharge barrel again simultaneously; the abrasive rubber layer that wear-resistant protective layer 12 can adopt abrasive rubber to make; it is the discharge barrel housing that material is made that discharge barrel housing 11 then adopts carbon steel, and can abrasive rubber layer and discharge barrel housing 11 be fixed together by the mode of bonding and constitute the discharge barrel of composite bush formula.Like this, when in the quartz sand process, quartz sand particle just separates by abrasive rubber layer and discharge barrel housing 11, thereby only rub with the abrasive rubber layer, this enters the problem that the quartz sand product pollutes with regard to having been avoided quartz sand particle and discharge barrel housing 11 that fricative iron filings take place, not only reduce the difficulty of quartz sand product deironing in the subsequent handling, improved the quality of quartz sand product, and reduced the quartz sand production cost of products.Aborning, can adopt the thick carbon steel discharge barrel housing of 8mm, under the prerequisite of the intensity that has guaranteed discharge barrel, also reach the purpose that alleviates discharge barrel weight, make things convenient for people the use of discharge barrel and the consumption of the energy according to the condition of production of reality.
Composite discharge barrel of automatic mill of the present utility model not only is applied on the autogenous tumbling mill in the quartz sand processing industry, equally also can be applied on the autogenous tumbling mill of autogenous grinding processing of other products such as ore, slag, ballstone.
