The utility model discloses a wind that the air -supply line got into arouses that the tiny particle material that the air current drove after the grinding flies upward the come -up, get into the decompression chamber after because pressure reduces suddenly, the regrind of sinking naturally of the great material of granule, the less through -put pulsating collection ware of granule is collected, has realized the automatic feeding of material and has got rid of, can make the equipment continuous operation.

Description

A kind of roller cuts grater grinding storehouse

Technical field

The utility model relates to a kind of roller and cuts grater grinding storehouse.

Background technology

In industrial and agricultural production, often need to adopt grinding machine to carry out pulverization process to various material.Grinding machine, according to the difference of milling medium and grinding material, can be divided into: ball mill, column mill, rod mill, tube mill, autogenous tumbling mill, revolve mortar formula roller mill, Vertical Mill, multilayer Vertical Mill, vertical roll grinder, DMC grinding machine etc.Generally intermittent ball mill is adopted in Ceramic production, adopt wet production, its abrasive action can be divided into two parts, one be between abrasive body and abrasive body and simplified between abrasive action, two be abrasive body fall time percussion, will start with from these two aspects to improve grinding efficiency." much broken and lessmill " technology of metallic ore and technique are one and have carried the topic of a lot of years, reduce the mill feed size of ball mill, before ball mill, increase by one section of pre-grinding or ultrafine grinding technique, are the important technology innovations that bargh saves energy and reduce the cost.The research of grinding machine rock processing is one of emphasis in Mineral Processing Engineering technology.Rock processing be utilize energy to extrude ore by grinding machine, roll extrusion, impact and grinding, make valuable mineral monomer cleavage in ore (from), be beneficial to the process that the next stage carries out sorting.

Grinding machine is applicable to pulverize the Mohs' hardness such as barite, calcite, potassic feldspar, talcum, marble, lime stone, gypsum, quartz, atlapulgite, active carbon, bentonite, kaolin, glass, manganese ore, titanium ore, chrome ore, slag and is not more than 7 grades, the nonmetallic mineral that the non-flammable of humidity below 6% is explosive.Grinding machine adopts mill revolution, the rotation of mill axle, spring to adjust cane grinding roller assembly structure, strengthen grinding roller roller skin to express material intensity and shear ability; thus reach the effect of strengthening abrasive dust; have output high, grind the fineness of materials high (powder is careful) come, old-fashioned grinding machine can the continuous powder process of dry method (stream time can not more than 24 hours), because the bearing in old-fashioned grinding roller assembly uses lubricating grease (lubricating grease must be shut down and be annotated once so can not more than 24 hours in 24 hours).But new-type is that the life cycle using lubricating oil (being commonly called as machine oil) can reach whole grinding roller owing to employing the lubricating oil the longest available machine time is shut down once, changes grinding roller and lubricating oil inspection (supplementing some lubricating oil again when needing).

Traditional rotary type grater comprises the cylindrical tube that the axis around basic horizontal rotates.The cylinder rotated is supplied with the such as granule materials such as slurry or powder, and cylinder rotates with 3/1 to four/2nds of " critical speed " (that is, the material at cylinder inner surface place contacts and the minimum speed of advancing around it with grater) simultaneously.Material mostly cannot realize automatic feed and discharging, easily cause material in feed pipe and grinding storehouse in pile up, cause the situation grinding inefficiency.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, the wind providing a kind of blast pipe to enter causes air-flow to drive the small particles material after grinding to fly upward floating, after entering decompression chamber, because pressure reduces suddenly, the material that particle is larger sinks to again grinding naturally, the material that particle is less is collected by pulse dust collector, achieves automatic feed and the eliminating of material, and the roller of equipment continuous operation can be made to cut grater grinding storehouse.

The purpose of this utility model is achieved through the following technical solutions: a kind of roller cuts grater grinding storehouse, establish the grinding warehouse of feed arrangement and lapping device in comprising, be positioned at the decompression chamber ground above warehouse, the discharge pipe being positioned at decompression chamber top and the blast pipe be positioned at outside grinding warehouse, described blast pipe is positioned at grinding warehouse outside one end of bottom surface, blast pipe is arranged around grinding warehouse, described discharge pipe inside is provided with pulse dust collector, and blast pipe is provided with multiple air admission hole with the side of grinding warehouse joint.

The beneficial effects of the utility model are: establish feed arrangement and lapping device in grinding warehouse, after material is ground, by blast pipe air intake, the wind that blast pipe enters causes air-flow to drive the small particles material after grinding to fly upward floating, after entering decompression chamber, because pressure reduces suddenly, the material that particle is larger sinks to again grinding naturally, the material that particle is less is collected by pulse dust collector, achieve automatic feed and the eliminating of material, equipment continuous operation can be made, and the circulation of air-flow can take away the heat that equipment produces, minimizing equipment is due to the fault caused of generating heat, extension device service life.

Description of reference numerals: 1-grinds warehouse, 2-decompression chamber, 3-discharge pipe, 4-pulse dust collector, 5-blast pipe.

Detailed description of the invention

Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing, but the content that the utility model is protected is not limited to the following stated.

As shown in Figure 1, a kind of roller cuts grater grinding storehouse, establish the grinding warehouse 1 of feed arrangement and lapping device in comprising, be positioned at the decompression chamber 2 ground above warehouse 1, the discharge pipe 3 being positioned at decompression chamber 2 top and the blast pipe 5 be positioned at outside grinding warehouse 1, described blast pipe 5 is positioned at grinding warehouse 1 outside one end of bottom surface, blast pipe 5 is arranged around grinding warehouse 1, described discharge pipe 3 inside is provided with pulse dust collector 4, and described blast pipe 5 is provided with multiple air admission hole with the side of grinding warehouse 1 joint.

Those of ordinary skill in the art will appreciate that, embodiment described here is to help reader understanding's principle of the present utility model, should be understood to that protection domain of the present utility model is not limited to so special statement and embodiment.Those of ordinary skill in the art can make various other various concrete distortion and combination of not departing from the utility model essence according to these technology enlightenment disclosed in the utility model, and these distortion and combination are still in protection domain of the present utility model.
