1. Superphosphate cannot be mixed with alkaline fertilizers such as grass ash, lime nitrogen, and lime. Because calcium superphosphate contains free acid, which is acidic, and the alkaline fertilizer contains more calcium, if the two are mixed, it will cause acid-base reactions, reduce the fertilizer efficiency, and it will cause calcium to fix phosphorus, leading to "two loses." . 2. Alkaline fertilizer such as calcium magnesium phosphate fertilizer cannot be mixed with ammonium ammonia fertilizer. Because alkaline fertilizers and ammonium ammonia fertilizers such as ammonium sulfate, ammonium bicarbonate, ammonium chloride, etc., will lead to and increase the volatilization loss of ammonia, reducing fertilizer efficiency. 3. Farmyard manure such as manure and urine can not be mixed with calcium, magnesium phosphate, grass ash, lime and other alkaline fertilizers. Because the main component of human and animal urine is nitrogen, if it is mixed with a strong alkaline fertilizer, it will neutralize and fail. 4. Fertilizer can not be mixed with rhizobia fertilizer and other bacterial fertilizers. Because chemical fertilizers have strong corrosiveness, volatility, and water absorption, if they are used in combination with bacterial fertilizers, they will kill or inhibit viable bacteria and make the fertilizer useless. 5. Ammonia cannot be mixed with human excreta, grass ash, potash, ammonium phosphate, potassium chloride, urea, and ammonium bicarbonate. Ammonium bicarbonate must not be mixed with plant ash, human waste, and potash nitrogen. Ammonium sulfate cannot be mixed with ash and ammonium bicarbonate. Ammonium nitrate cannot be mixed with grass ash, ammonia, etc. If the fertilizer mentioned above is mixed and applied, it will cause acid-base neutralization reaction and reduce the fertilizer effect. 6. Phosphate rock, bone powder and other insoluble phosphate fertilizer can not be mixed with alkaline fertilizer such as grass ash, lime ammonia, lime. Otherwise it will neutralize the organic acids in the soil, making it harder to dissolve insoluble phosphate fertilizers, and crops cannot absorb and use them.
Classification of tablet press: Models can be divided into single punch tablet press, rotary tablet press, sub-high speed rotary tablet press, automatic high speed tablet press and rotary core tablet press.
The sheet shape pressed by the tablet press is initially flat circular, and later developed into shallow circular arc and deep circular arc on both sides, which is for the need of coating. With the development of special-shaped tablet press, oval, triangle, oblong, square, diamond, circular ring tablets followed. In addition, with the continuous development of preparations, due to the requirements of compound preparations and timed release preparations, special tablets such as double layer, triple layer and core coating are made, which need to be completed on special tablet press.
Rotary tablet press is a machine which is made of several pairs of die distributed on the turntable to make a circular lifting movement according to a certain track and press the granular material into tablet through the press wheel. And the stamping rod with the rotary table rotating speed ≥60m/min line press is called high-speed rotary tablet press, this high-speed rotary tablet press has a forced feeding mechanism, the machine is controlled by PLC, has the automatic adjustment of pressure, control the weight of the piece, eliminate the waste piece, print data, display fault shutdown and other functions, in addition to the control of the weight difference within a certain range, Quality problems such as missing Angle and loose lobe can be automatically identified and eliminated.
With the development of market demand, the scope of application of tablet press is more and more wide, no longer simply limited to the suppression of Chinese and Western medicine tablets, more widely suppressed health food, veterinary medicine tablets, chemical tablets: such as mothballs, washing blocks, smurf blocks, art powder, pesticide tablets, food tablets: chicken essence block, isatis root block, divine Qu tea block, compressed biscuits.
