Abstract
The utility model discloses a Raymond mill for producing silicon carbide micropowder. The Raymond mill comprises a Raymond mill main machine (1), a Raymond mill main drive motor (10), a feeding hole (2), a bin (10) and a conveying pipe (4), wherein an electromagnetic virbator (5) is arranged on the conveying pipe (4), and suspended in air through a suspending mechanism (6). According to the Raymond mill, an electromagnetic vibration feeding mechanism is arranged at the lower part of a charging bin, and materials can be quantitatively, continuously and uniformly fed in a main machine grinding chamber, so that a main motor always works in an optimal load state, the production efficiency of a procedure is greatly increased when the quality is ensured, the energy consumption is reduced, the condition that blockage is easily caused and even the motor is burnt up caused by original manual operation of a worker is prevented, and the continuous operation of field production equipment is ensured.
Description
Technical field
The utility model relates to a kind of silicon carbide micro-powder production Raymond mill.
Background technology
Silicon carbide micro-powder is the desirable line cutting blade material of solar energy crystal silicon chip, semiconductor.Powder process is the important procedure during silicon carbide micro-powder is produced, and because the hardness of carborundum is higher, its Mohs' hardness is 9.5 grades, in Mohs' hardness standard only lower than diamond, so its production and processing being not easy.The accuracy of Raymond mill main frame feed is directly connected to yield rate and the output of micro mist, and the yield rate of silicon carbide micro-powder and the height of output have directly determined again the economic benefit of enterprise.By repetition test, find, in silicon carbide micro-powder production process, the accurate control to the main motor feed of Raymond mill, can improve yield rate and the output of silicon carbide micro-powder greatly, makes more steadily operation reliably of equipment.
The course of work of current Raymond mill is as follows: granularity sand enters main frame grinding chamber by feeding chamber, after grinding roller and bull ring grinding, under air-introduced machine effect, drives powder to carry out sorting through being placed in a grader of grinding chamber top.The excessively thick particle of granularity again falls within grinding chamber and returns mill, and the particle that granularity meets the specification enters No. two grader accurately sortings again, and qualified granularity is through test package.
At present between feeding chamber and air channel, use pipeline to be connected, by feed manually, every grinding machine needs an operative employee to stand on charging scffold to constantly reinforced in feed bin, and granularity sand enters in main frame grinding chamber naturally by the conveyance conduit of feed bin bottom.
Its defect is that operative employee's labour intensity is large, and inefficiency particularly cannot guarantee reinforced accuracy, and the situation that usually there will be conveyance conduit to stop up, and causes fracture to shut down.
If delivery rate is faster, the granularity sand that the unit interval enters main frame grinding chamber is more, and the resistance being subject between grinding roller and bull ring is larger, and the load of main motor is just larger, and its electric current raises.Feeding coal too conference causes main motor rotation blockage and makes electric current rising even burn main motor, and feeding coal is too little makes again main motor dally, and affects production efficiency, waste electric energy.Therefore in order to guarantee production efficiency, delivery rate accurately need to be controlled in suitable scope.
