Abstract
The invention belongs to the technical field of superfine solid powder grinding, and particularly relates to a superfine powder preparing method. The method for processing peat soil plant remains to be of the particle size below 5 micrometers at normal temperature and normal pressure includes the steps that the peat soil plant remains with the organic matter content above 50% are pretreated to be of the particle size below 1 mm, wherein the water content is 5%-15%; the remains are placed into a three-stage controllable orbital-transfer ball mill, wherein a grinding barrel is divided into three grinding bins through three screening fences of different hole diameters, and three kinds of grinding balls of different sizes and quantities are placed into the three grinding bins; and the grinding barrel is driven by a variable frequency motor to vibrate in the horizontal and vertical directions with variable amplitudes and frequencies. Accordingly, the superfine powder grinding effect of step-by-step refining, adjustable impulse and controllable particle sizes is achieved.
Description
Technical field
The invention belongs to solid superfines grinding technology field, particularly peat soil plant remains superfines preparation method.
Background technology
Usual peat soil plant remains, also known as brown coal, sapropel, particle size is comparatively large, and physical and chemical performance is stablized, water insoluble.But when its particle diameter reaches several microns, just can show some special physical and chemical performances, such as: solubility several times increase, and be conducive to plant absorption nutrient, crop growth power and immunity obviously strengthen; To hardening, soil can play loose effect, improves rapidly soil organism state, accelerate growth of microorganism, is of great significance Improvement of Ecological Environment.
Traditional content of organic matter is greater than 50% peat soil plant remains fine-powder preparation process, temperature generally will more than 85 DEG C, some special macromolecule functional groups in organic matter are destroyed, and cause effect of its most worthy to be lost, and can only play common organic fertile effect.And traditional peat soil plant remains powder is generally about 200 orders, and 2000 object peat soil plant remains powder effects are than 200 height of eye decades of times.But at normal temperatures and pressures, current preparation method is difficult to peat soil plant remains to be ground to 2000 orders, needs to break through existing techniques in realizing.
The present invention is on the basis of existing ball mill, proposing the preparation method of three grades of controlled change rail ball mills, increasing momentum by changing track, increase is simultaneously ground cabin and is changed abrading-ball size and realizes powder granular step by step, then, powder delivery particle size is controlled by screen.Combinationally using these methods, solves the problem of solids powder mull to particle diameter 5 microns (2680 order).
Summary of the invention
The present invention proposes the peat soil plant remains superfines preparation method of three grades of controlled change rail ball mills.Comprise following part:
1), by the pretreatment of natural peat soil plant remains to particle diameter less than 1 millimeter, water content 5% ~ 15%, is transported to three grades of controlled change rail ball mills;
2), ball mill mill tube comprises the screen fence that three are respectively 100-500um, 30-80um, 5-20um different pore size, mill tube is divided into three mill cabins by three screen fence, places the abrading-ball that three kinds of diameters are the different size of 15-30mm, 10-15mm, 3-10mm respectively in three mill cabins;
3), mill tube two ends are fixed in the track of two equidirectionals and size, and be fixed in the middle of mill tube on the arm of force flexible up and down, the track at mill tube two ends is fixed on the arm of force of horizontal motion, the arm of force of both direction is driven by variable-frequency motor, forms controllable variable track vibromill;
4), two identical controlled change rail vibromills, utilize a central point to connect the arm of force of horizontal direction, make two mill tube horizontal direction symmetrical operations, balance is positioned over support.
5), the vibration frequency of the arm of force of level and upper and lower two vertical direction is 10-60Hz, and amplitude is 5-38cm, by variable-frequency motor power adjusting.
6), from material inlet to outlet, the magic ball of descending different-diameter and the screen of different meshes are placed in three mill cabins; Material outlet screen is at 1340-3000 order, and material grinding finished product grain size is less than 10 microns.
7), mill tube and grinding ball material have stronger heat conduction, corrosion-resistant, impact resistance, as strengthening steel.
Essential characteristic of the present invention is:
One, controllable variations track increases the momentum of spheroid, makes grinding charge receive more strike;
Two, vibration frequency, amplitude and variation track are adjustable controlled, and momentum is changeable;
Three, the size of ball radius and the change of number make powder attenuate step by step;
Four, the screen pore size control particle diameter of powder reaches corresponding grinding effect with the corresponding relation of the size and number of abrading-ball;
Five, mill tube inwall and abrading-ball select shock-resistant, corrosion-resistant, that heat conduction is fast material can reach temperature control effect and service life.
Example one
By natural peat soil in drum through rotary-cut, the wind of less than 65 DEG C is blown in rotary-cut process, water content is made to reach 10-12%, through normal temperature Cemented filling to feed bin, the alkali (NaOH) of even blending 6%, by a downward Cemented filling to three grades of controlled change rail ball mill entrances, three grades of controlled change rail ball mill frequency 50Hz, amplitude 30cm in the horizontal direction, under the vibro-grinding of vertical direction frequency 20Hz, amplitude 10cm, powder delivery 500kg per hour.
Example two
By natural peat soil in drum through rotary-cut, the wind of less than 55 DEG C is blown in rotary-cut process, water content is made to reach 5-15%, through normal temperature Cemented filling to feed bin, the alkali (each half of CaO and NaOH) of evenly blending 10%, by a downward pipeline, naturally fall, be transported to three grades of controlled change rail ball mill entrances, three grades of controlled change rail ball mills under the vibro-grinding of frequency 40Hz, amplitude 20cm, powder delivery 400kg per hour.
