Potassium feldspar belongs to monoclinic crystal system, its color is usually red, yellow, white and other colors, density 2.54-2.57g/cm3, specific gravity 2.56-2.59, hardness 6, potassium feldspar ore is so far the potassium content is high, the distribution of relatively speaking is relatively wide, rich storage of non-water-soluble potassium resources.
Potash can be successfully produced from potash feldspar by sintering:
Sintering method is in fact the limestone and coal as raw materials, after crushing, molding in the kiln inside the calcination, so that the potassium oxide into water-soluble substances, sintering method of production costs are lower, the beauty of its production process is higher energy consumption.
The processing flow of potassium feldspar is:
Potassium feldspar raw materials - hand-selected - crushing - grinding - classification - dehydration - finished products, the process is suitable for raw materials with low iron content and good quality. Jaw crusher is used for coarse crushing and fine crushing, in order to prevent the contamination of iron on potassium feldspar during processing, so it is easy to use MTW European mill or LM vertical roller mill, ultra-fine vertical roller mill and so on as the grinding equipment when choosing the grinding equipment, which is simple in the process and less investment.
Rough crushing using C6X series jaw crusher usually take the motor drive as the power source, the motor through the SPC belt will input the power to the pulley, the pulley drives the eccentric shaft rotation to drive the movable jaw body for front and back up and down swing. When the movable jaw plate is close to the fixed jaw plate, the volume of the crushing chamber decreases, and the materials in the crushing chamber are squeezed or chopped; when the movable jaw plate is far away from the fixed jaw plate, the volume of the crushing chamber increases, and the crushed materials in the crushing chamber are discharged from the discharge opening, so that the crushing is realized by continuous cyclic movement.
CI5X series impact crusher is a kind of crushing machine which utilizes impact energy to crush materials. When working, the motor drives the rotor to rotate at a high speed, when the material enters the plate hammer area, it will be crushed by the high-speed impact of the plate hammer, and the crushed material will be thrown to the counterattack plate installed on the top of the rotor in the tangential direction to be crushed again, and then bounced back to the plate hammer area from the counterattack plate to be crushed again. This process is repeated until the material is crushed to the required size and discharged from the discharge port. Adjusting the gap between the impact frame and rotor can achieve the purpose of changing the material size and shape.
LM Vertical Mill--Powder Making
LM Series Vertical Mill is mainly composed of grinding roller assembly, grinding disk assembly, hydraulic station, transmission arm assembly, powder selector, main reducer, electric motor, body, main reducer lubrication station, hydraulic station, PLC electric control cabinet and other parts. The main motor drives the mill to rotate through the reducer, at the same time, the hot air enters into the vertical mill body from the air inlet, the material falls in the middle of the mill from the lower material outlet, under the action of centrifugal force, the material moves evenly from the middle of the mill to the edge, when passing through the milling roller track area on the mill, it will be milled by the mill roller, the big material will be crushed directly, and the fine material will be formed into the bed for inter-granular crushing after being extruded.
