Dense hammer crushing and dividing combined sample preparation confidential sealed hammer crushing a

  Dense hammer crushing and splitting combined prototype , Sealed hammer crusher wqpcs1 / 8 sealed hammer crusher combined prototype uses ring hammer crusher to conduct rapid impact and cyclic crushing of materials, and make samples with particle size less than or equal to 13mm, 6mm or 3mm through screen plate adjustment, which can be automatically reduced, and the quality accounts for about 1 / 8 of the total feed
For material samples with large moisture content, crushing and sample preparation are also suitable, which can replace manual continuous crushing and multiple sample preparation procedures, and the obtained samples are accurate and reliable
Structure and working principle: wqpcs1 / 8 hammer crushing and splitting combined prototype is mainly composed of hammer crushing and splitting mechanisms, which are combined into one by the frame
(1) The hammer crushing mechanism is mainly composed of casing, shaft, hammer core, etc
when the motor is started, it drives the hammer core to rotate rapidly through belt drive
At this time, the hammer head generates great centrifugal force and opens outward to form an impact ring
When the material enters the impact ring, it will be crushed, Through the sieve plate hole (the discharge particle size can be adjusted by selecting the sieve plate with different holes)
(2) the shrinkage mechanism is mainly composed of small single groove belt wheel, triangular belt wheel, large single groove belt wheel, crank connecting rod Pull sliding rod (cutting rod), chain, splitter, quarterer and retraction sliding rod
After the shaft rotates, the small single groove belt wheel drives the large single groove belt wheel
The crank connecting rod on the large single groove belt wheel pulls the pull sliding rod to move up and down
The pull sliding rod is connected with the chain, the quarterer and the quarterer are respectively tied at both ends of the chain, and the chain drives the quarterer and the quarterer to make water along their respective sliding rods The coal sample from the hammer crusher is reduced and divided through the quadrant and dichotor successively
Working mechanism: the coal sample enters the hammer crusher and is crushed
The coal particles with particle size less than the L diameter of the sieve plate enter the classifier through the sieve
The coal particles with particle size greater than the aperture of the sieve plate continue to be crushed in the crusher until the particle size is reduced to pass through the sieve hole
The coal sample entering the divider is first reduced to 1 / 4 by the quarterer, and then enters the divider to be reduced to 1 / 2
Finally, the laboratory coal sample with the particle size reaching the specified particle size and the quality of 1 / 8 of the man-machine coal sample quantity is obtained
2、 Main technical parameters: feed particle size & lt; 150mm discharge particle size & lt; 13mm．< 6mm and & lt; 3mm (adjustable) shrinkage ratio is about 1:8, adapt to moisture (total moisture) 18 /% treatment capacity 800 & mdash; 1500kg / h, spindle speed 940r / min, sieve plate sieve hole diameter 20mm, 13mm and 6mm (optional) motor model 112m-4 motor power 4kw power supply 380 overall dimension 1250mmx780mmx1600mm mass about 420kg III
installation, use and maintenance 1
Equipment installation: the sealed hammer crushing and splitting combined prototype is an assembled complete machine
When the user receives the machine, he shall check it to eliminate the possible abnormalities of the equipment during transportation
(2) during equipment installation, The machine body shall be smoothly installed on the concrete foundation to reduce vibration and noise (3) After the motor is powered on, the rotation direction of the motor belt wheel must be consistent with the direction mark of the crusher
