Phosphate rock shipped from mine, under normal circumstances, the size is
generally less than 200 mm, its production must first be broken, then make it up
to a certain fineness, or will become a "concentration" of the
pulp.
According to the size of broken material, usually phosphate rock
crushing process is divided into coarse crushing and middle crushing. First
broken ore into 0-50 mm diameter block, known as the primary crushing; then
after crushing ore broken into 10-25 mm or smaller mineral particles, known as
middle crushing and then sent for grinding operations.
Phosphate rock crusher
is currently used mainly in two types: jaw crusher, impact crusher
1, Jaw
crusher
Jaw crusher is commonly used phosphate rock crushing equipment, it
works with the fixed jaw plate and mobile jaw plate compression to crush
phosphate, in accordance with its moving trajectory it can be divided into
simple swing , complex swing and integrated swing. Complicated swing used more
in small and medium phosphate fertilizer plant, because it is shaping equipment,
plant selection can be based on production capacity.
2, Impact
Crusher
Impact crusher is a high efficiency crushing equipment. It is
generally used as a phosphate rock middle crushing and it has a simple
structure, small size, light weight, high crushing ratio, small power
consumption. The disadvantage is that hammer and impact plates wear faster, need
to be replaced regularly.
Follow the steps to ensure safety of jaw
crusher
1.Preparation and Inspection before running
(1) Check the
operation of equipment anchor bolts and bolts loose, the protective cover of the
rotating equipment are complete.
(2) Check the jaw crusher tooth plate,
lining the connecting bolts loose or falling debris and crusher cavity with or
without iron.
(3) Check whether the operation of equipment, lubrication oil,
gear oil level is adequate within.
(4) Check the belt of active and passive
wheel is loose and damage, whether deviation, the roller is off, retaining the
skin, blade is intact.
(5) Check whether the debris and around obstructions,
lighting equipment is complete, ensure the device is in normal state before
driving too, and get through the accident switch.
2. Running
When
receiving the order to drive, running the machine step by step. Until the device
is working properly, contact with the crane job, switch to chain and chain
position. Jaw crusher is used to crush big block phosphate. when big block
phosphate is not too much, you can not open the jaw crusher feeder, so that the
ore can be directly into the next program.
3. Stopping
When receive the
stopping information from colleagues, the jaw crusher staff stopped job
notification for mine, stop plate feeder, until the belt and jaw crusher without
material in them, it can be stopped then. And the stopping order is opposite to
running order.With its high quality products such as 、、、Henan
Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in
the exporting of mining equipments.
