At this stage, works with the growing increase in the amount of sand, resulting in the supply of sand and gravel aggregate natural sand mining operations is difficult to meet the market demand. Mechanism of sand or artificial sand industry is gradually on the rise, driven by the construction machinery industry research and improvement of the heavy mineral processing equipment and processes. Integral part of the impact of broken, as the core of sand and gravel production line due to its important position in the entire mechanism of sand production, the stability and durability of its components becomes important. Injection of materials play a decisive role impeller device is the most important component of the impact of broken, the stability of its work to determine the work efficiency of the whole mechanism of sand production line.

Impeller is both the impact of breaking the most important part of the same time also the most vulnerable parts of the materials that complete the launch of the impeller, improper operation, it is easy to cause the material to wear impeller, so we work and operation should be particularly precautions so as not pay attention, do not accidentally trigger a series of accidents in production. We know that the impeller installed on the top axis of the spindle assembly of the head of the pass button from the cone kits and key connection, high-speed rotation, and the material from the center of the impeller part of the reel into the center of the impeller. Launch flow to the impeller emission flow from impeller center fabric cone material a uniform distribution, export, installation made of special materials wear block can be replaced. Impeller to accelerate the material to a certain speed projectile out the impact of the vortex crushing cavity lining materials strong since crushed between impeller cone hats and wear block is equipped with, indecent Road board to protect it does not subject to wear and tear. It should be noted that when the device stops the operation: first stop before the stop nesting feeding, feeding should be continued uniform, material specifications strict compliance with the requirements, or is likely to cause impeller wear.

When we know the mechanism of impact-breaking work, can be carried out on the optimization of workflow. Machinery Co., Ltd. in Shanghai Kefid solemnly remind our customers, and the routine maintenance of the impact of breaking the impellers should be noted that the following 10 areas:

First: car checked before vortex crushing chamber to observe the door closed to prevent the materials from the vortex chamber observed door out of danger.
Second: Check the impeller direction of rotation from the direction of the feed inlet. The impeller should rotate counterclockwise, otherwise it should be adjusted to the motor wiring.
: Sand and transportation equipment startup sequence as follows: nesting → Sand → feed; crusher must load starting to be the crusher before feeding in normal operation. Stop order is contrary to the boot sequence.
Fourth: feed particles strictly follow the regulations prohibit greater than the specified materials into the crusher, otherwise, would be too much wear and tear caused by the imbalance of the impeller and impeller base to cause clogging impeller channel and center into the barrel, the crusher is not normal found that the chunk into the material should be immediately removed.
Fifth: the discharge device stopped moving, should be in time to stop feeding, otherwise, will result in crushed impeller, burned the motor.
Sixth: strive to continuous and uniform feeding.
Seventh: The crusher operation process, without excessive vibration and unusual noise, otherwise, you should stop and check.
Eighth: To ensure the impact breaking energy efficient transmission of the impact of broken triangular belt tensioning size should be adjusted to appropriate, to ensure that the triangular tape Force uniform, two-motor drive, both sides of the triangle tape packet matching, then each of its The head of the degree is as consistent as possible.
Ninth: regular downtime Open observation door to observe the impact of broken internal wear, the center feed tube, cone hat, impeller, the lining of the downstream Road, Zhou shield, wear block wear, wear and tear shall promptly replace or repair, replacement of wear blocks should all be replaced at the same time to ensure that the wear blocks weigh the same.
X: the impact of breaking the 400 hours per work by adding the right amount of grease to work 2000 hours to open the bearing spindle assembly, cleaning, general work 7200 hours and replaced with new bearings.

In addition, high-performance impeller is also essential. Order to extend the service life of the impact of broken, Shanghai Kefid Machine Co., Ltd. developed successful use of high-manganese steel structure to improve the vortex rotation, launch speed automatically adapts to adjust the new impeller device, the process performance can be 1.2-1.5 times the normal shocks break As a result of the high wear-resistant structure and optimization of the upper and lower liner, can effectively enhance the impact of broken life for the user to save money and cost recovery.
