How To Ensure Safty Phosphate Rock Processing
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
