The double roll breaker leaves the material granularity the adjustment: Two rollers between turn are loaded with wedge-shaped or the filling piece adjusting device, the sector mount peak is loaded with the adjustable bolt, when the adjustable bolt pulls up upwardly the visor, the visor goes against the live action roller wheel to the fast pulley, namely two roller turn gap fill-out, leaves the material granularity fill-out, when visor downward, the live action roller turn is contracting the spring the function next two turn gap to change small, leaves the material granularity to change small. The filling piece installment is adjusts the material granularity size through fluctuation filling piece quantity or thickness, when increase filling piece two roller turn gap fill-out, when reduced filling piece two roller turn gap changes small, leaves the material granularity to change small.
5 Breaker uses
The correct use and the maintenance breaker, to sharpen the handling ability, lengthen its service life are very important, also is the safety in production must.
The breaker type and the working condition are different, thus, time use should pay attention to the next several points:
1) Breaker starting. First should start the oil pump and the cooling system, after passes through 3~5 minutes, treats the right road unimpeded in the start breaker electric motor. Because the breaker is the heavy load equipment, regardless of therefore what kind of type, should the idling starting. Sometimes to some large-scale breakers, still needs with the aid of the external force starting.
2) Breaker operation. To already the breaker which starts, should first idle operation several minutes, when the idle operation may inspect the base, the guard plate chain and so on, if does not have exceptionally, starts for the material. If installs newly the breaker, should cause its time of idle running long somewhat, but the idle operation feeds in raw material again two after three operating shifts. The breaker for the material must be continuously even, prevents the overload, moreover in entire for the material mouth width in for estimated should be consistent, like this may cause the breaker to receive grinds evenly, lengthens the easy wearing parts relatively the life.
In stave regarding the dry process, enter the material moisture content not to be able excessively to be high, like hammer type breaker; When aqueous method screening, then must maintain the suitable water volume, prevented because of flushes the water insufficient to stop up, decreases the handling ability.
Also should prevent the hard material like hammer head and the corner iron and so on fall within the aircraft. When operation, should follow the working instruction, prevented violates regulations to create the man-machine accident.
3) The breaker works the time inspection and nursing. Works when the breaker, should inspect the stave product granularity whether conforms to the requirement, like the discovery surpasses the stipulation granularity the pellet excessively to be many, should discover the reason, like sieves the good slit oversized, dump attrition and so on mouth width, hammer, Huber board or pin roll excessively perhaps the protector becomes less crowded and so on, and takes the suitable measure to eliminate. Simultaneously pays attention to the bearing temperature to surpass not suitably 50℃, the normal oil temperature should in 30~35℃ about, in order to guarantee the lubricating oil the quality, should clean the fuel tank regularly, discharges the pollutant. If is the drying oil lubrication, should the periodic inspection and pours into the fresh oil.
4) Before the breaker parking, should stop giving the material first, machine material row only, then according to smooth closure main motor and lubrication electric motor. If the belt material engine off,very easy to create the part damage. If appears the accident engine off, after also should machine the material elimination, be able to start. 破碎机英文文献和中文翻译(7):http://www.751com.cn/fanyi/lunwen_77420.html
