Procedures before Ball mill Export
<h1>Procedures before Ball mill Export</h1>
Ball mill export face multiple inspection process such as Delivery
Inspection, running inspection and export inspection. Repeated inspection
process raise higher requirement to ball mill production, and now let’s talk
about it one by one.
1, Delivery inspection: each ball must be approved by delivery inspection,
and accompanied by certificate.
2, Delivery inspection items: delivery inspection must follow the rules
below:
A, basic requirements for ceramic ball mill: should be consistent with the
GB / T14253 regulations
B, safety and health: the ball mill rotating part should be solid, reliable
and safe. The parts that may affect people safety should adopt corresponding
safety measures; ball mill operation should be of no abnormal noise; no-load
test noise should be lower than the specified.
C, electrical equipment should comply with relevant standards.
D, performance requirements: ball mill should be kept stable rotation and
flexible operation, reliable sealing performance, no loose phenomenon in each
successive piece. No-load operation must be operated more than 2h and satisfy
the requirement: normal operation; no leakage in gearbox main bearing; balanced
running and no obvious vibration phenomenon;
E, load test (only after qualified no-load test) must be operated more than
12h and satisfy: work balance, no obvious vibration phenomenon; no leakage in
gearbox main bearing; point temperature measuring is below 80 Celsius degrees in
ball mill main bearing, temperature rises should be kept within 40 Celsius
degrees; no loose phenomenon between fasteners.
F, ball mill should be installed stop positioning device, especially for
whose cylinder body inner diameter is larger than 2700mm.
G, service life of complete machine and the main components should accord
to the rulers strictly.
3, Type Inspection
Type Inspection should be carried out if only any of the following
circumstances:
A, new or old test pattern evaluation products in transferred
factory;
B, product performance may be affected by bigger change in the structure,
material, technology after formal production;
C, restore production after more than a year stopping;
D, big difference between delivery inspection results and the last type
inspection;
E, national quality supervision mechanism put forward type inspection
requirements;
F, 1 to 2 should be tested when cumulative production of 100.
4, Type inspection items:
Test items should be according to the above mentioned items. Ceramic ball
mill product quality evaluation adopts all-targets-achieved method which asks
that: products would be classified unqualified if the main technical parameters
of ball mill do not meet the above requirements; or the other technical
inspection items cannot be up to the standard after repairing or
adjusting.
With its high quality products such as Cement mill price, Hammer crusher, Ore flotation equipment, Hammer crusher, Raymond mill, Henan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
