VSI Series centrifugal impact crusher is on the basis of our
company’s many years’ research and development, manufacture of mining machinery
as well as absorbing home and abroad advanced technology. It is the
international advanced level of the new generation of energy-saving, efficient
crusher. the performance in a variety of ores a chronology of equipment plays an
irreplaceable role.
The machine can be widely used in metal and non-metallic
minerals, building materials, sand making, crushing and shaping of all kinds of
metallurgical slag. It is suitable for brittle materials with Mohs hardness
under nine, not suitable for viscous material and rock with much dirt.

VSI Series Vertical Shaft Impact Crusher Working
Principle:
In Centrifugal impact crusher, material of high speed is
crushed by self-broken mutual friction. Centrifugal impact crusher can not only
crush but also shape stones.
According to feeding method, centrifugal impact
crusher working form is divided into central feeding and central with cascade
feeding. The crush form is divided into “rock on rock’ and “rock on iron”
According to material compressive strength, abradability. There are four working
forms: central with cascade feeding “rock on rock” and rock on iron”; central
feeding “rock on rock” and rock on iron”.
VSI Series Vertical Shaft
Impact Crusher Daily Maintenance:
1〉There should be some person
responsible for the machine. Operator should be trained. understand technical
performance of the equipment, familiar with the rules.
2〉To keep machine
smooth running, draw out regulations of machine maintenance and safe operation.
Meantime prepare necessary maintenance tools, lubrication material and other
related equipments.
3〉Check firmware every shift, fasten immediately if any
flexible.
4〉Stop the machine termly, open the checking door and check inside
wear condition. Replace and remove immediately if any wear, werable block should
be changed whole set if any wear to keep impeller balance in running. Replace or
repair immediately if any wear on impeller.
5〉Check impeller firmware every
7 days, wearable parts should be replaced and repaired if any wear.
6〉Check
firmware and wearable parts in whirlpool chamber every half a month, if any
abnormal condition, take immediate means to remove.
7〉Thin oil station use
35# bearing oil, oil amount is 150-190L. Change oil in 200hours first time, then
change oil every 1000. when change oil, open the oil pipe, clean and dry it,
change damaged seal mat.
8〉Driving V belt tensioning is moderate, make sure v
belt strain evenly, motors in two sides are imbalanced, the electricity current
is not more than 15A.
9〉Check hydraulic system frequently, maintain
immediately if any abnormal phenomenon.
10〉Add calcium base grease to seal
ring under bearing chamber regularly.
11〉Open the bearing tube and clean in
1000 hour’s normal running first time.
