Description
The utility model relates to a kind of dry method grinding device that is used for the material of industries such as building materials, mine.
Raymond mill be widely used in various in, softer material a kind of centrifugal milling equipment, but there is the defective of following primary structure and usefulness aspect in Raymond mill: (1 grinding roller directly contact with bull ring and makes the impulsive force increase, weares and teares and aggravates, consumable accessory life-span weak point; (2) grinding power source is a centrifugal force, and concerning many materials, it is not enough that grinding power seems; (3) there is the big sliding friction of root in perching knife feeding, makes power consumption and wearing and tearing aggravation.
The purpose of this utility model is the defective that overcomes above-mentioned prior art, and the roller mill that a kind of grinding power is big, mill efficiency is high, power consumption is low, wearing and tearing are little, abrasive dust power is adjustable, noise is lower, Technological adaptability is wide is provided.
The purpose of this utility model is to realize by following technical scheme.It is made up of main shaft, drive plate, spreading disk, spring, Burnisher apparatus, abrasion-proof backing block and body, base, discharge bucket etc., it is characterized in that body is interconnected to integral body by upper machine body, middle body, main shaft places on the bearing, bearing block is fixed on the upper machine body, drive plate is located in the middle body, be fixed on the main shaft, spreading disk is housed on it; Hole or groove offering at least on the drive plate more than two or two install and fix cover in hole or the groove, and Burnisher apparatus is installed in the fixed cover; Above middle body lower flange elastic device is set, the quantity of elastic device is more than 2 or 2; Elastic device is made of spring, spring base, pretension screw rod etc., and spring adopts metal or nonmetallic materials, is the solid stage clip, or is liquid spring or gas spring.Between middle body and base, stopping means is set, the scope that the restriction base moves down.Stopping means is made of adjusting pad, adjusting lever etc., adjusts gap length between grinding roller and the abrasion-proof backing block by the thickness of adjusting pad.Base inner wall is established abrasion-proof backing block, and the base bottom sets out hopper.The grinding roller outer wall is smooth or non-shiny surface.Abrasion-proof backing block inwall bus and ground inclination, its inner wall surface are shiny surface or non-shiny surface.
The utlity model has following technique effect:
1, a reasonable clearance is arranged between grinding roller and abrasion-proof backing block, avoided the direct collision of powder grinding medium;
2, elastic device provides material to pulverize required grinding power, can adjust the size of grinding power at different material;
3, material falls the sliding friction when having avoided feeding certainly by gravity.

The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in drawings, the utility model is made up of drive 1, main shaft 4, drive plate 6, grinding roller 11, upper machine body 3, middle body 8, base 9, abrasion-proof backing block 10, elastic device 7, stopping means 16, discharge bucket 12 etc.Upper machine body 3, middle body 8 connect firmly by attachment bolt, and the bottom surface of middle body 8 801 is installed on the basis by bolt.Be provided with stopping means 16, elastic device 7 and guider between middle body 8 and the base 9, make the two existing active force close to each other, keep a kind of position relation that can move mutually again.Wall is provided with abrasion-proof backing block 10 within the base 9, wall bus and ground inclination within the abrasion-proof backing block 10, and inner wall surface can be shiny surface or is processed into the non-shiny surface of band serrate slot.The upper surface 802 of middle body 8 lower flanges is provided with elastic device.Upper machine body 3 is provided with charging aperture, and bearing block 2 is connected on the upper machine body 3, is provided with bearing in it.Main shaft 4 is contained on the bearing block 2 by bearing, bearing cap etc., can rotate under the drive of drive 1, and drive plate 6 is fixed on the main shaft 4 by key and nut, is arranged in body 8, establishes a spreading disk 5 on it.When main shaft 4 rotations, spreading disk 5 and drive plate 6 rotation synchronously under it drives.On drive plate 6, offer two or two above holes or groove at least, a fixed cover 15 respectively is installed in each hole or the groove.Burnisher apparatus is installed in the fixed cover 15, by bearing grinding roller 11 can be relatively rotated around self axial line 14.For improving friction between grinding roller 11 and abrasion-proof backing block 10 inwalls, to be convenient to material and to enter, the inner wall surface of grinding roller 11 outer walls and abrasion-proof backing block 10 can be processed into the non-shiny surface of being with serrate slot etc.For making grinding roller 11 and abrasion-proof backing block 10 keep reasonable clearance, stopping means 16 is set, can adjust the gap of 10 of grinding roller 11 and abrasion-proof backing blocks, avoid the direct collision of 10 of grinding roller 11 and abrasion-proof backing blocks again.In the present embodiment, elastic device 7 is made up of nut 701, upper spring seat 702, spring 703, lower spring cup 704, spring spiro rod 705.Spring 703 is metal compression spring.The size of spring force is adjusted by the decrement that nut 701 changes spring 703.Spring force acts on the base 9 by spring spiro rod 705, forms motive force upwards, thereby material is pulverized.Spring also can be arranged on the bottom of base 9 upper flanges, comes conveniently but adjust, check, keep in repair, install all not as the top of body 8 lower flanges in being arranged on.According to the operating mode needs, between middle body 8 and the base 9 guider can be set, the stationarity during with increase work.
The utility model, spring 703 can adopt metal or nonmetallic materials, also can be hydraulic spring grease cup or gas spring.
During work, rotor part such as grinding roller 11 is rotated synchronously thereby main shaft 4 drives spreading disks 5, drive plate 6.After material enters from A, spread wall within middle body 8 by spreading disk 5, fall to entering wall within the abrasion-proof backing block 10 at gravity effect lower edge inwall, 11 of grinding rollers rotate around self axial line 14 under frictional force and material drag effect, thereby roll material, grinding pressure is the spring force that acts on the base 9.Adjust the spring force size and can adjust grinding power size easily.By the material that grinding is crossed, discharge from discharging opening B.Thickness of feed layer, product grade constitute and can control by the gap length between angle, grinding roller 11 and the abrasion-proof backing block 10 of grinding power size, abrasion-proof backing block 17 inwalls, the influence factors such as flow velocity of material outlet.
