Abstract
A method for increasing the efficiency of continuous ball grinder and decreasing its energy consumption features that the rotation speed of ball grinder is regulated to 20-60% of the highest speed and the ball grate is additionally used at its inlet and outlet for increasing its internal density of material. It can increase power output by 50% or more and decrease energy consumption by 5% or more.
Description
Technical field
The invention belongs to the powder processing technique field, particularly a kind of method of improving the continous way ball mill.
Background technology
Superfine technique has become one of important deep process technology of industrial mineral and other raw material as a new engineering.The continous way ball mill is a kind of common abrading type disintegrating apparatus; It is widely used in the grinding of the common fineness of industries such as mine, metallurgy, chemical industry, building and electric power; It has simple in structure, running rate advantages of higher; But also there are a series of problems such as, power consumption height low, in particular for high fineness grinding operation such as work efficiency.Need to strengthen of the impact grinding effect of the interior medium ball of mill in the common crushing process to bulk materials, the filling rate of tradition continous way ball mill is no more than 40%, the drum speed rate is greater than 70%, when this traditional ball mill is used for high fine lapping operation, should strengthen the abrasive action of medium ball to material, make that like this operating efficiency of ball mill is very low, effectively utilization rate of electrical is about 2% only, and its efficient can not be given full play to.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, propose a kind of method of improving the continous way ball mill.It is characterized in that: by adjusting the rotating speed of 1.2 meters of barrel diameters, long 4 meters ball mills, the rotational speed rate that makes cylindrical shell is 30～60%, and adopt in the inner feed inlet and outlet of grinding machine front and respectively set up the grate plate of blocking, the filling rate that makes grinding machine is 60～80%, 325 order talcum powder are ground, thus improve ball mill efficient, cut down the consumption of energy.
Beneficial effect of the present invention compared with prior art has following advantage:
1) owing to adopted 60～80% filling rate, increases mill output so the grainding capacity of small size abrasive media can be brought into play effectively.The raising of filling rate can reduce the eccentric throw of abrasive media center of gravity when rotating, partial offset rotate needed moment of torsion or grinding machine input power because of loading increases grinding machine.
2) owing to adopted 30～50% rotational speed rate, more much lower than the rotational speed rate of traditional ball mill barrel, so effective to the abrasive action of product, the input power that grinding machine needs also is reduced.
3) owing to changed the rotational speed rate and the filling rate of ball mill, the move distance of abrasive media reduces, so this stable processing technique and reliability are improved.
The specific embodiment
The present invention proposes to be used for a kind of method of improving the continous way ball mill of high fineness process of lapping.Main by adjusting the rotating speed of 1.2 meters of barrel diameters, long 4 meters ball mills, make the rotational speed rate of cylindrical shell between 30～50%, respectively increase the grate plate of blocking with the inner feed inlet and outlet of grinding machine front, to improve filling rate between 60～80%, 325 order talcum powder are ground, the output of the unit power fine powder of ball mill under such running parameter is maximum, make traditional ball mill can be applied to high fine lapping operation, improve unit power fine powder output, thereby improve efficient, the energy efficient of ball mill; Fundamentally overcome the big deficiency of inefficiency, power consumption of ball mill.Only the present invention is further specified below for embodiment.
Embodiment one
Adopt 1.2 meters long ball mills of 4 meters of barrel diameter, the rotational speed rate of adjusting ball mill is 50%, and filling rate is 80%, and other parameters are fixed, and 325 order talcum powder are ground.With filling rate be 40%, rotational speed rate is that 70% situation (running parameter of general traditional ball mill) is compared, unit load power exceed 59% less than 10 μ m product yields, bearing power low 4.9%.
Embodiment two
Adopt 1.2 meters long 4 meters ball mills of barrel diameter, making its rotational speed rate of ball is 30%, and filling rate is 60%, and other parameters are fixed, and 325 order talcum powder are ground.With filling rate be 40%, rotational speed rate is that 70% situation (running parameter of general traditional ball mill) is compared, the output less than 10 μ m products of unit load power exceeds 52%, bearing power low 5.2%.
From the result of above two embodiment, it is a lot of that bearing power is descended, and ball mill unit load power fine powder output exceeds more than 50%, and bearing power descends more than 5%.Therefore compared with prior art, this method breaks through traditional concept, has produced significant effect.
