Abstract
The invention discloses a fixed roller type crude grinding machine, wherein a hollow central shaft bracket and a grinding ring are arranged on the base of a main body, a main shaft is arranged in the central shaft bracket, the upper end extending outside the central shaft bracket of the main shaft is provided with a fixed roller rack, a plurality of grinding roller assemblies which are parallel to the axis are mounted on the fixed roller rack evenly, each grinding roller assembly comprises a grinding roller jacket and a grinding roller which are fixed in an adjustable manner so that an adjustable gap can be formed between each grinding roller and the grinding ring. The adjustable fixing manner adopts the eccentric setting of the grinding rollers and the grinding roller jackets, the rotation manner of the grinding roller jackets, the swinging manner, which is adjusted with a level, of the grinding roller jackets or the translation manner of the grinding roller jackets. The gap of the invention can be conveniently adjusted according to the particle size and hardness of the feed and the fineness of finished products, then the grinding machine can be configured to a feeding machine, a grading machine, a collector and a draught fan to form an complete powder processing system, and the grinding machine has higher efficiency and environmental friend and is an ideal equipment of the coarse powder processing system.
Description
(1) technical field:
The present invention relates to the powder process equipment, is a kind of fixed roller type crude grinding machine specifically.
(2) background technology:
20～60 purpose powders (belonging to meal in the industry) generally require the powder narrowly distributing, and plate glass raw material especially is as quartz: its high-class product-150 order content≤5%; Grade A-150 order content≤10%.Using more process equipment in the market is rod mill and block mill pulverizer.Their subject matter is that the processing technology control difficulty of powder is big, instability, powder granularity wider distribution, energy consumption greatly, not environmental protection.
And flour mill is a breeze sector application equipment the most widely, once also considered to come replacement bar grinding machine and block mill pulverizer to produce 20～60 purpose powders with flour mill, but the mach powder order of abrasive dust number is at 80～325 orders, with respect to 20～60 purpose powders has been fine powder, and-150 order content be difficult to control, the powder order number that does not also have at present technological means control flour mill makes it to become the special equipment of producing meal.
(3) summary of the invention:
At the weak point of tradition processing meal equipment, the present invention proposes a kind of flour mill process principle that utilizes and produce 20～60 order powders and-150 order content less than 5% fixed roller type crude grinding machine.
Can realize the fixed roller type crude grinding machine of above-mentioned purpose, comprise main frame, host form and Raymond machine are similar, be on the base of main frame hollow center pedestal and coaxial bull ring to be housed, main shaft is located in the pedestal of center, fixed roll frame (or claiming the plum blossom frame) is equipped with in the main shaft upper end of stretching outside the pedestal of center, by jockey a plurality of (3～8) and central axes are installed evenly on the fixed roll frame and are the grinding roller assembly of circle distribution, the grinding roller assembly is made up of grinding roller cover and grinding roller, different is that the grinding roller cover of described grinding roller assembly and the jockey between the fixed roll frame are the fixed roll device that can regulate gap between grinding roller and the bull ring, in the revolution process of grinding roller assembly, keep identical setting gap (being that grinding roller does not directly contact with bull ring) between each grinding roller and the bull ring, and the grinding roller assembly that does not resemble Raymond machine makes by centrifugal action and keeps in touch between each grinding roller and the bull ring, thereby effectively control powder and cross pulverizing, reach the purpose of producing meal.
Described fixed roll device has multiple structure, mainly contains following several:
1, described fixed roll device is a chuck, and chuck is fixedly installed on the fixed roll frame, and the grinding roller cover of grinding roller assembly is clamped in the chuck, is provided with the anti-rotation limited part between chuck and the grinding roller cover, and the grinding roller main shaft is eccentric the installation in the grinding roller cover.Unclamp chuck and rotate the grinding roller cover, can change the eccentric degree of grinding roller main shaft, thereby regulate the gap between grinding roller and the bull ring.
Used limited part is key or screw.Key is embedded in grinding roller and puts and be engaged in the keyway that correspondence is offered on the chuck; Screw fit inwardly turns and tightens up the grinding roller cover on chuck.
Be grinding roller cover easy to setup, described chuck is the semicircle gland, dehisces to be connected with the semicircle of fixed roll frame by bolt.
2, described fixed roll device is the brute spring plate, the brute spring plate is tightened against the fixed roll frame with screw by the horizontal slot of offering on it, the overhanging end of brute spring plate connects the grinding roller cover, slot can be realized the certain displacement of brute spring plate (grinding roller cover), thereby regulates the gap between grinding roller and the bull ring.
3, described fixed roll device is a leverage, leverage comprises balance staff and two swing arms, balance staff is located on the fixed roll frame, two swing arms are connected with balance staff respectively in the balance staff both sides, one swing arm is tightened against the fixed roll frame by regulating pad with bolt, another swing arm is overlapped with grinding roller and is fixedlyed connected, and makes the swing of grinding roller cover by changing the thickness of regulating pad, thereby the gap between adjusting grinding roller and the bull ring.
The same with flour mill, main frame of the present invention also disposes batcher, grader, gatherer and air-introduced machine, batcher connects the charging aperture of main frame, the meal outlet of main frame is installed grader, grader is connected with gatherer, gatherer is connected with air-introduced machine by pipeline, and air-introduced machine is communicated with the air inlet of main frame or is open close.
Advantage of the present invention:
Grinding roller did not directly contact with bull ring when 1, fixed roller type crude grinding machine of the present invention was worked, and had been limited certain clearance between them, can be adjusted to suitable gap easily according to feed size, hardness and the finish fineness of material, produced the meal of required order number.
2, fixed roller type crude grinding machine configuration feed of the present invention, classification, collection and induced draught system make it to reach efficient, environmental protection requirement.
