Abstract
A shot blasting type pulverizer comprises a spherical shell, a motor, a spindle, a fine powder collecting system and a fan, the longitudinal section of the spherical shell is elliptical, a discharging port and a feeding port are arranged on the top and on the upper side portion of the spherical shell respectively, an air inlet is arranged on the lower side face of the spherical shell, the discharging port is connected with the fine powder collecting system through a guide pipe, the spindle is mounted at the center of the spherical shell, the spindle inside the spherical shell is spiral in shape, a driving plate is mounted at the bottom of the spindle, and a funnel type tray is sleeved outside the spindle in the spherical shell and is fixedly connected with the spherical shell. The shot blasting type pulverizer has the advantages that the motor is controlled by a variable-frequency controller, and shot blasting speed can be adjusted flexibly by adjusting the rotational speed of the motor, so that collision of a steel ball to materials can be guaranteed to be completed, the ground materials can reach the top of the spherical shell, and a continuous pulverizing process is completed; and according to different requirements on finish fineness, system air quantity is adjusted randomly, qualified fine powder can be discharged out of the spherical shell timely, pulverizing efficiency is improved beneficially, and over-pulverizing is avoided while energy consumption is reduced.
Description
Technical field
The present invention relates to a kind of ball blast type flour mill.
Background technology
Grinding technology is widely used in a plurality of industries such as metallurgy, electric power, ore dressing, chemical industry, building materials.Ball mill is owing to the strong adaptability to various materials, and milling capacity is high, and device fabrication is simple, can adapt to the reasons such as various production requirements, is widely adopted within a very long time.But its capacity usage ratio is very low, and seriously polluted, and potentiality and the development space of its technological transformation have been gone to the end, can't satisfy the requirement of current energy-conserving and environment-protective.The main cause of traditional ball mill high energy consumption, the basic principle that is ball mill are to treat grind materials and grinding steel ball, freely fall after taking certain altitude to by cylindrical shell rotation again, by steel ball material are produced and thump and abrasive action.Have, adopt the ball mill of open system, material will all reach release mesh just can go out mill, easily produces the grinding phenomenon, has equally also increased ineffective energy consumption.
Summary of the invention
Purpose of the present invention just provides a kind of reliability and product quality that had both had traditional ball mill, and the higher-energy effective rate of utilization is arranged again, and can adapt to the ball blast type flour mill of various materials grinding requirement.
Ball blast type flour mill of the present invention, comprise spherical shell, motor, decelerator, main shaft, frequency-variable controller, the fines collection system, blower fan, be characterized in, the spherical shell longitudinal cross-section is oval, spherical shell top and upper lateral part evenly arrange respectively discharging opening and charge door, the spherical shell lower side has air inlet, blower fan is connected with air inlet on the spherical shell by airduct, discharging opening links to each other with the fines collection system by conduit, main shaft is installed in the spherical shell center by the scroll-up/down bearing, the main shaft upper end is connected with motor by decelerator, the main shaft profile of spherical shell inside in the shape of a spiral, and main shaft bottom is equipped with driver plate, the funnel type pallet is nested with the main shaft outside in spherical shell, and be fixedly connected with spherical shell, as admitting steel ball and being input to usefulness on the main shaft spiral.
The operation principle of ball blast type flour mill of the present invention is during machine operation, to drive the main shaft rotation by decelerator, at this moment material and the steel ball of the driver plate stirring spherical shell bottom of main shaft bottom.The centrifugal force of driver plate rotation orders about steel ball and accelerates and penetrate material to get rid of to the spherical shell inwall, then scroll up along the spherical shell inwall, both finished process of lapping, and arrive the spherical shell top, steel ball falls into the funnel type pallet afterwards, and sequentially falls in the main shaft helicla flute along the funnel type pallet, steel ball descends at a high speed through the main shaft rotation and obtains kinetic energy, break away from main shaft through main shaft when bottom, again penetrate material and finish bump and grinding to material, this process repeats to be the ball blast grinding continuously.Material enters in the spherical shell through the feeding raw materials from more than one places mouth continuously, blower fan forms negative pressure to spherical shell inside, qualified fine powder behind grinding is immediately extracted spherical shell out and is entered the cyclone cylinder of fines collection system from discharging opening, and the hot blast that blower fan is extracted out from spherical shell can be recycled, and again sends back in the spherical shell by demand.
Ball blast type flour mill of the present invention, the control of motor employing frequency-variable controller gets final product flexible modulation ball blast speed by the regulating electric machine rotating speed, and the assurance steel ball can be finished the rear spherical shell top that arrives of bump, grinding to material, finishes continuous grinding process; According to the different requirements of finish fineness, random regulating system air quantity, qualified fine powder can in time be discharged spherical shell, is conducive to improve mill efficiency, and avoids the formation of grinding, reduces simultaneously energy consumption.
