Standard operating procedures for type 30b crusher

Standard operating procedures for type 30b crusher: before operation and production, check whether the equipment is hung with "cleaning certificate" If it indicates that the equipment is in normal state, remove this plate and hang the operation state sign Operators shall wear work clothes and safety masks as required Check whether the equipment, materials and auxiliary tools and instruments in the working room have been positioned Check whether there are sundries stacked on the table top of the distribution box, the working table of the crusher and the surrounding space, and remove the items irrelevant to the work Before operation, check whether all parts of the equipment are assembled completely and accurately, and whether there are scrap iron and other sundries in the hopper and the main engine cavity, and remove them if necessary Check whether the belt tightness of the main engine is normal and whether the belt protective cover is firm; check whether the fasteners such as the lock screw of the rack and the main engine compartment door and the motor foot are firm Check whether the aggregate bag is installed correctly and firmly When rotating the spindle by hand, observe whether the spindle is flexible and unimpeded If there is obvious stagnation, find out the cause and remove the obstacles Move the power switch of the control distribution box Jog the starting host to confirm whether the rotation direction of the motor is consistent with the direction of the arrow Note: there is no independent inching control button in this machine, which is completed by panel start button and stop button operation; that is to say, press start button, the motor rotates After starting, press stop button immediately, the motor stops running Observe the motor rotation direction before the motor reaches the static state due to inertia Jog and start the dust suction motor, and confirm whether the rotation direction of the motor is consistent with the direction of the arrow Before operation, prepare to start the machine for operation after checking and confirming that there is no error Operation press the start button of the dedusting unit, and the dedusting machine starts After the fan runs stably, press the start button of the pulverizing main engine, and the main engine starts to run After the above motor is started, it will run for about 2 minutes without load After observing that the main engine and dust suction fan run stably without load, it can be fed Put the materials to be crushed (Zui large feed particle size 8-12mm) into the hopper for stacking, adjust the size of the feed gate, rely on the vibration of the machine itself, so that the materials can be sent to the crushing chamber at the set speed The load of the main motor shall be controlled to work within the rated value (the rated power of the main motor of the machine is 5.5kW), and the feed rate of the feeding material shall be adjusted properly according to the material property, crushing fineness and cutting speed, so as to avoid the car blocking accident and ensure that the main engine works under the rated working condition Scope of application: This machine is suitable for crushing and drying brittle materials; it is not suitable for crushing materials with low softening point and high viscosity The fineness adjustment factor maintains the appropriate feed rate; the wear degree of the shear cutter and the fixed gear ring in the grinding bin is adjusted by the grinding chamber after screening; whether the collector channel of the finished product is smooth and good Qualified materials crushed by the crushing chamber enter the aggregate barrel through the discharge port The operator can observe the collection of the products through the observation window installed on the aggregate box panel When the collection amount of the crushed products is more than 2 / 3 of the barrel, the aggregate barrel shall be replaced or the qualified powder in the aggregate barrel shall be cleaned The operation of replacing the aggregate drum shall be carried out in the shutdown state After the grinding operation is finished, shut down the machine in the following order: close the feed regulating gate and stop feeding to the grinding bin After stopping feeding, the whole machine will continue to run for about 2 minutes Press the stop button of the main machine when there is no powder in the aggregate barrel, and the main machine will stop running After the main engine stops stably, press the stop button of the dust suction fan to stop the fan The machine is equipped with bag type dust remover, and can shake the vibrator to vibrate the bag properly Clean the bag in each shift If the variety is changed, clean the bag according to the cleaning procedures Clean the equipment according to the cleaning procedures after operation Operation safety and precautions during the operation of the equipment, it is forbidden for the operator to contact with the transmission part of the equipment It is forbidden to spray and clean the equipment with water Where the oil cup is installed, appropriate grease shall be injected before driving, and check whether there is enough grease in the rotating part Check the wear condition of blade, lining ring and gear disc regularly, which will make the grinding granularity coarser after wear, and report in time if serious wear is found The particle size of Zui large feed is 8-12mm Materials must be inspected before crushing, and no metal sundries are allowed to enter the crushing room without preparation before operation and inspection of all items before operation.
