Abstract

The present invention relates to an improved method for a grinding material. The material is filled in an ice pipe, and the ice pipe filled with the material is frozen to form a composite ice column. The ice column is ground from one end on a grinding machine. The outer pipe is used for preventing material from dispersing too early and too fast, so the material can be fully ground. The method ensures that the material is ground into fine powder once with low cost.

Description

Disintegrating method

For example the present invention relates to a kind of pulverizing: the method for fibrous materials such as feed, paper pulp, bamboo or plastic material.

Various known breaking methods are arranged, and wherein, method of the present invention can reduce Ginding process.Typical existing Ginding process as shown in Figure 5, treats that broken material grinds in socle mill, this burrstone mill has the mano 10 of a fixing metate 11 and a rotation.But material once being worn into granularity in this way is difficult less than 200 purpose powder, therefore, must carry out sorting repeatedly and grinding to material.In addition, well-known, for this stone mill type grinder of prior art, when material one contact rotation stone mill,, the half of materials end has been blown away through pulverizing with regard to being arranged.Therefore, not only efficient is low but also waste is big for this customary way.

Purpose of the present invention grinds method with regard to providing a kind of material of the problems referred to above of avoiding.

Method according to ground material provided by the present invention.Comprise the following steps: to treat that broken material packs in the pipe; And pipe is ground together with the material that is mounted in it from an end of pipe.

Material can keep in touch for a long time with grindstone, thereby makes material can once wear into sufficient fine powder, and can owing between material and the grinding stone friction not cause overheated.

According to the present invention, this pipe is to be made of the material different with treating broken material, and it is used for limiting material wherein and prevents that the material discharge from can not fully grind too soon in process of lapping.

Treat that broken material is contained in the pipe that is made of the material with abundant hardness, like this, after two kinds of materials are all pulverized, can be with any suitable method, for example: Magnetic Isolation method, gravitational separation process or fusing separation, condensation separation, centrifugation, separate tubing with treating broken material.Tubing can be metal, plastics or the liquid that freezes.

When treating that broken material soaks into maybe may soak into liquid the time, be loaded in the pipe, then it is freezed.Filling the pipe for the treatment of broken material begins to contact with grindstone from the one end.The inventor finds that this pipe by contact the material that can prevent the inside with grinder, was particularly blown away before grinding near peripheral material prematurely.

From the description below in conjunction with accompanying drawing, further feature of the present invention and purpose will be more readily apparent from, wherein:

Fig. 1 is full of the freezing outer tube sectional view for the treatment of broken material;

Fig. 2 is the simple sectional view of belt-type grinder, and how polished the outer tube for the treatment of broken material is filled in expression is;

Fig. 3 is an outer tube sectional view of being treated broken refrigeration material by made of iron and filling;

Fig. 4 is the grinder sketch map of the another kind of type of the method according to this invention;

Fig. 5 is the sectional view of the method for expression prior art.

Now referring to Fig. 1, (for example: feed) for example put into the sub-1(of an ice tubulation, its measured value is among external diameter 100mm * internal diameter 80mm * 200mm) to the broken material (2) for the treatment of that mixes with water, and is frozen into the icicle 4 that is made of the chilled water that has scattered material 2.

As shown in Figure 2, icicle 4 begins to contact with belt-type grinder 5 from the one end under pressure, thereby icicle is worn into fine powder.This powder will disperse against the inwall of the shell 6 of grinder and be collected in the container 7 with pasty state.With the pasty mass dehydration and the drying of collecting, just be left the material 2 that is ground by uniform, fine.

As shown in Figure 3, the outer tube made from iron 1 ' replacement ice pipe 1, thus material can be removed with the Magnetic Isolation method with the iron powder that pipe 1 ' clay into power and the material 2 that grinds mix.

Fig. 4 shown the grinder 5 of another kind of type ', wherein, be installed in the fixing outer tube 8 of making by iron or steel the ice pipe 4 for the treatment of broken frozen material 2 is housed, by catch bar 9 to the grinder motion and should ice pipe discharge from fixing outer tube 8.In this embodiment, outer tube 8 is with treating that broken material grinds.

According to the present invention, outer tube can with treat that broken material grinds together, after grinding, with treat that outer pipe powder that broken material mixes is from wherein removing.

Outer tube can also be made with treating the material that broken material mixes by can or wishing.

According to the present invention, the frictional heat that grinder and treating produces between the broken material keeps minimum of a value, if outer tube is freezing, can grinds material and needn't worry its performance variation.In addition, because material can once be worn into fully thin powder, like this, make it when reducing production costs, can improve production efficiency.Method of the present invention can be used for grinding such material, as grain, medicine, plastics and elastomeric material.

Claims

1, a kind of method that is used for ground material comprises the following steps: and will treat the broken material pipe of packing into, and the pipe that this material will wherein be housed grinds from an end.

2, method according to claim 1, wherein, above-mentioned pipe is frozen into tubular formation with metal, plastics or with liquid.

3, method according to claim 1, wherein, above-mentioned pipe by can or the expectation make with treating the material that broken material mixes.

4,, wherein, above-mentionedly treat that broken material is frozen behind the above-mentioned pipe of packing into according to claim 2 or 3 described methods.

5, according to any described method among the claim 1-3, wherein, the above-mentioned pipe that material is housed is put into an outer tube, in the time should managing the release outer tube, ground.

6, method according to claim 4 wherein, is put into an outer tube with the above-mentioned pipe that material is housed, and grinds in the time should managing the release outer tube.
