Description

A kind of be applicable to roller cut grater material grinding storehouse

Technical field

The present invention relates to a kind of be applicable to roller cut grater material 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.The material of traditional grater cannot realize automatic feed and discharging mostly, easily cause material to pile up in feed pipe, and after stopping feed, the material in feed bin all cannot enter in cylinder and grind, need manually to clear up, the low and waste of manpower resource of production efficiency.

Summary of the invention

Detailed description of the invention

Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing, but the content that the present invention protects is not limited to the following stated.

As shown in Figure 1, a kind of be applicable to roller cut grater material grinding storehouse, comprise warehouse 1, be positioned at the decompression chamber 2 above warehouse 1, and be looped around the airduct 3 outside warehouse 1;

Described warehouse 1 comprises the feed pipe 11, feed bin 12, discharge nozzle 13 and the U-shaped annular groove 14 that are provided at its inner portion, the charging aperture of feed pipe 11 stretches out the side of grinding warehouse 1, the discharging opening of feed pipe 11 is connected with the feeding mouth of feed bin 12, feed bin 12 is fixedly mounted on rotating shaft 15, the side of feed bin 2 is provided with at least one feed bin discharge hole 121, feed bin discharge hole 121 is fixedly connected with discharge nozzle 13, and the discharging opening of discharge nozzle 13 connects U-shaped annular groove 14;

Described feed bin 12 is the column construction that top and bottom are regular polygon, each side of feed bin 12 is rectangle, feed bin discharge hole 121 lays respectively in each rectangle sides of feed bin 12, a cone 122 using feed bin bottom surface as bottom surface is provided with in feed bin 12, the height of described cone 122 is lower than the height of feed bin 12, and the summit of cone 122 is positioned at the body-centered place of feed bin 12;

Described airduct 3 is provided with multiple air admission hole with the side of warehouse 1 joint, and the installation site of airduct 3 on warehouse 1 is positioned at above U-shaped annular groove 14; As shown in Figure 2, airduct 3 is spirality, blast pipe 3 comprises blast pipe 31, airduct body 32 and discharge pipe 33, blast pipe 31 and discharge pipe 33 lay respectively at the both helical ends of airduct body 32, blast pipe 31 is positioned at the spiral outer end of airduct body 32, and blast pipe 31 discharge pipe bodies 32 are around the part of warehouse 1, the spiral that discharge pipe 13 is positioned at airduct body 32 is inner, discharge pipe 33 is communicated with airduct body 32, the diameter of described discharge pipe 33 is less than the diameter of airduct body 32, and the diameter of airduct body 32 is less than the diameter of blast pipe 31.

Operation principle of the present invention is: material enters feed bin 12 by feed pipe 11, material to be sprinkled upon the many places in U-loop groove 14 by feed bin 12 by discharge nozzle 13 by the feed bin discharge hole 121 that is arranged on its side, material is ground, in fill process, a cone 122 is set in feed bin 12, the design of this ramp structure, make material enter feed bin 12 and enter rapidly discharge nozzle 13 afterwards, improve the gliding speed of material, ensure the supply of material in U-loop groove 14, can also avoid because supports for material down-sliding causes feed bin 12 to occur the situation of solid accumulation not in time, and after stopping blanking, material in feed bin 12 can all enter U-loop groove 14, without the need to manually carrying out material cleaning work, save manpower, enhance productivity.After material being ground in warehouse 1, by airduct 3 air intake, the wind that blast pipe 3 enters causes air-flow to drive the small particles material after grinding to fly upward floating, after entering decompression chamber 2, because pressure reduces suddenly, the material that particle is larger sinks to again grinding naturally, the material that particle is less enters collecting device by the outlet above decompression chamber, 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 due to the fault that causes of generating heat, extension device service life.
