Abstract
The utility model relates to a mechanical impact super-fine powder grinder, particularly an improvement of a stone powder processing machine. The utility model is characterized in that a main shaft is driven by a motor through a belt or a hydraulic motor. The main shaft is fixed in the middle of the outer wall of a crushing area through a bearing, and a rotor is horizontally fixed to the main shaft of the crushing area. The rotor is provided with a wind blade. The inner wall of the crushing area is a curved surface, and a blade type classifier is fixed at the outlet of the upper part of the crushing area through the main shaft. The outside of the classifier is connected with a discharge port, and the top of the outer wall of the crushing area is fixed with a feed tube inserted into the crushing area. The utility model has the advantages that the crushable materials are multiple, the grinding rate is optional in the range of 1-100 micrometers and the consumption of energy is low.
Description
The utility model belongs to non-metal ore advanced processing technical area, relates to a kind of improvement of stone flour processing equipment.
At present, process superfine powder in the world generally with two kinds of equipment, be airflow milling and sand mill, airflow milling is to utilize compressed air to produce high velocity air, drive material and under high speed, clash into mutually, thereby realize being crushed to below 10 microns, utilize grader to select the micro mist of certain particle size again, its deficiency is the energy consumption height, and energy consumption is about ten times of flour mill.Sand mill is the wet type mill, make bead with hard objects, material and ball are contained in barrel formula container, use the agitator high-speed stirred, by ball and material friction that material is levigate, though more energy-conservation than airflow milling, the consumption of post processing and mill ball also makes production cost only decrease than airflow milling, but the reduction amplitude is little.In addition, two kinds of grinding machine feed sizes generally need 44 microns more than.
But but the purpose of this utility model provides the mechanical shock formula superfine powder grinding machine of a kind of not only common grinding but also extra-fine grinding.
The technical solution of the utility model is as follows:
Motor drives main shaft by belt or hydraulic motor, main shaft is being pulverized in the middle of district's outer wall by bearing fixing, horizontal fixed has rotor on the main shaft in pulverizing the district, fan blade is arranged on the rotor, pulverizing district's inwall is curved surface, be fixed with the vane type clasfficiator in exit, top, pulverizing district by main shaft, the clasfficiator outside is communicated with discharging opening, is fixed with the feed pipe that the district is pulverized in feeding at outer wall top, pulverizing district.
Pulverize district's inwall curved surface and be preferable over the parabolic surface that rotates formation around vertical axis.
Pulverizing district's inwall curved surface can be made up of the short-term regular polygon.
The utility model has the advantages that: but 1 grind materials is wide, can grind any fragile material of Mohs' hardness below 7,, pulverizes district's inwall curved surface and can use the short-term regular polygon less than 5 as the Mohs' hardness of material; But 2 grinding rates are optional at the 1--100 micron; 3, energy consumption is low, is example with the calcite, and material size is milled to 10 microns (d90) less than 20 millimeters, and 250 kilowatt-hours/ton, shepardite is milled to 4 microns (d90), 220 kilowatt-hours/ton.
Fig. 1 is a structure cut-away view of the present utility model.
Below in conjunction with accompanying drawing the utility model is described further:
Wherein: the 1st, rotor, the 2nd is pulverized district's curved surface, the 3rd, motor, the 4th, striker plate, the 5th, feed pipe, the 6th, main shaft, the 7th, discharging blower fan, the 8th, vane type clasfficiator, the 9th, discharge zone, the 10th, dispersion area curved surface, the 11st, dividing plate, the 12nd, pulverizing chamber outer wall, the 13rd, dispersing chamber outer wall.
Motor drives main axis rotation by belt or hydraulic motor, material enters grinding machine continuously from feed pipe, falls on the rotor, and the rotor upper surface has the fan blade of protrusion, driving material rotates at the same rate, simultaneously centrifugal action outwards slides down, when arriving the edge speed be two speed vector and, throw to and pulverize district's curved surface, hit at not broken former material on curved surface on the curved surface or still to certain Cheng Du, form micro mist, under the blowing of rotor bottom wind, the material that minced flies to the dispersion area along curved surface.Can there be the blower fan air draught outside at discharge zone, therefore be subjected to two power effects at the dispersion area material: the one, the suction of wind outside, the one, gravity own, both directions are opposite, thinner is sucked away, and revolution that falls that grain is big continues to pulverize, the material that siphons away enters discharge zone through clasfficiator and delivers to outside the machine, and the material that does not reach granularity falls back to and continues on the rotor to pulverize.The effect of dividing plate is whole circumference to be divided into several pulverize the district, prevents that material from sliding in the same way in tangential velocity effect lower edge, reduces even loses crushing effect.
