Description

Roll the slag machine

Technical field

The utility model relates to a kind of slag machine that rolls.

Background technology

The grinding of material is to overcome cohesive force between its inner particle and crystal by effects such as abrasive body and storeroom extruding, impact, grindings, makes it to be become by bulk the process of powder shape.For ball mill, effective pulverizing merit that external force acts on material seldom generally only accounts for 1%-3%, and major part then has been consumed with forms such as heat, sound.This means improve grinding operation effectively utilize merit, especially power consumption is accounted for the various raw-material grinding of manufacture of cement overall process 70%-80%, cutting down the consumption of energy more seems very important.

Material is subjected to the crushing mechanism complexity of external force effect, both relevant with material properties such as grindability, moisture content, particle shape, mill feed size and product fineness etc., also in close relations with production technology, milling equipment etc., the influence factor of different working conditions has nothing in common with each other, and is difficult to be defined with a tube list formula.Therefore, correlation theory is incomplete as yet so far, but a lot of research still has certain value to application in practice.

The utility model content

The technical problems to be solved in the utility model is big in order to overcome material grinding plant energy consumption of the prior art, inefficient deficiency, and it is little to improve a kind of energy consumption, and material particular diameter is required the low slag machine that rolls.

For realizing above purpose, the utility model is achieved through the following technical solutions:

Roll the slag machine, it is characterized in that, comprise circular drum, be provided with abrasive body in the circular drum, abrasive body comprises two identical round platforms, and two round platforms use a common bottom surface as the less bottom surface of diameter, and the circular drum inner wall shape matches with abrasive body, have charging aperture and discharging opening on the circular drum, circular drum is placed on the plural roller bearing.

Preferably, described round platform bus is 5-20 ° with the angle of axle.

More preferably be that described round platform bus is 10 ° with the angle of axle.

Wherein, described discharging opening is opened on the close sidewall of circular drum bottom surface.

Wherein, described discharging opening is opened on the circular drum bottom surface.

Wherein, described roller bearing is by motor-driven.

Wherein, in the described circular drum wallboard is installed, has certain angle between wallboard and the circular drum inwall and match, between wallboard and the circular drum inwall gripper shoe is installed with grinding media shape.

The beneficial effects of the utility model are: 1, the device operation only needs by bottom wheel shaft driven rotary, and required energy consumption is minimum, only is 30kw; Noise is little during the equipment operation, and factory's circle noise is lower than 60dB (A) and reaches factory circle of industrial enterprise two noise like standards between daytime, be lower than 50dB (A) night;

2, the unique design of grinding media shape is ground the material that is clipped in itself and grinding machine inwall with himself gravity, and contact area is big, pulverizes effectively, and the discharging particle diameter is even, and improved grinding is abundant;

3, material flows naturally, need not external force guiding control;

4, low to the particle diameter requirement of processing materials, the range of work is big, and labor aptitude is strong.

The specific embodiment

Embodiment 1, referring to Fig. 1-Fig. 3, roll the slag machine, comprise circular drum 1, be provided with abrasive body 2 in the circular drum 1, abrasive body 2 comprises two identical round platforms 3,4, two round platforms have a bottom surface 6 that diameter is bigger respectively, 7, two round platforms 3,4 use a common bottom surface 5 as the less bottom surface of diameter, and round platform bus 11 is 5-20 ° with the angle of axle 12, is preferably 10 °, circular drum 1 inner wall shape matches with abrasive body 2, have charging aperture 8 and discharging opening 9 on the circular drum 1, circular drum is placed on two roller bearings 10, and discharging opening 9 is opened on the close sidewall of bottom surface.Roller bearing 10 also can be driven by other power set by motor-driven.

Embodiment 2, the difference of itself and embodiment 1 is, described discharging opening 9 is opened on circular drum 1 bottom surface, wallboard 13 is installed in the circular drum 1, wallboard 13 has a certain degree with circular drum 1 inwall, to match, gripper shoe 14 is installed between wallboard 13 and the circular drum 1 to support wallboard 13 with grinding media shape.

Using method, feed intake by charging aperture, material falls to being distributed between abrasive body and barrel naturally, start cylindrical shell bottom tourelle, make it to rotate in the same way the motion of drive cylindrical shell, abrasive body also rotates thereupon, and rolls material between between abrasive body surface and cylinder inboard wall by self gravitation, is discharged by the discharging opening at two ends, cylindrical shell bottom through the material after fully rolling.

Compare test with rolling the slag machine in the utility model with pre-grinding machine:

Use pre-grinding machine respectively and roll the particle diameter of slag machine before and after material is pulverized to distribute and see Table 1, Comparative Examples distributes for material being used the particle diameter of pre-grinding machine before and after pulverizing, and the test example is rolled the particle diameter of slag machine before and after pulverizing and distributed for material is used.

Table 1:

	Particle diameter distributes, mm	Comparative Examples 1	Comparative Examples 2	Comparative Examples 3	Mean value	Test example 1	Test example 2	Test example 3	Mean value
										Mill feed material	＞0.5	77.76	76.86	86.39	80.34	78.25	76.30	75.67	76.74
＜0.5	22.24	23.14	13.61	19.66	21.75	23.70	24.33	23.26
									Go out grind materials		＞0.5	49.99	51.20	45.61	48.93	29.01	33.13	30.58	30.91
＜0.5	50.01	48.80	54.39	51.07	70.99	66.87	69.42	69.09

As can be seen from Table 1: the discharging average grain diameter of material is littler after rolling the slag machine and milling, the average content of pre-grinding machine discharging particle diameter＜0.5mm material is about 51.07%, the average content that rolls slag machine discharging particle diameter＜0.5mm material is about 69.09%, improve about 18%, the raising of output when helping the production of road technology down.

Table 2 is for rolling the technical parameter table of slag machine and pre-grinding machine:

Table 2:

	Power of motor	Treating capacity per hour	The consumable accessory cost	Weight of equipment
					Pre-grinding machine	75kw	10 tons	8 yuan/ton	2400kg
Roll the slag machine	25kw	More than 15 tons	3 yuan/ton	2550kg

As can be seen from Table 2, contrast pre-grinding machine, it is all more excellent than pre-grinding machine to roll slag machine each side technical parameter, and electricity price is rolled the slag machine and per hour can be saved (75-25) * 0.75=37.5 unit by 0.75 yuan/degree; Produce 20 per year (hour) * 25 (my god) * 12 (moon)=6000 hour meter, can save electricity charge 6000*37.5=225 in 1 year, 000 yuan; Consumable accessory cost: can save consumable accessory cost consumption (8-5) * 30000=90,000 yuan in 1 year.

Embodiment in the utility model only is used for the utility model is described, and does not constitute the restriction to the claim scope, and other substituting of being equal in fact that those skilled in that art can expect are all in the utility model protection domain.
