Higher Ball Formation Rate Fertilizer Pelletizer Organic Fertilizer Granulating Machine The new type organic fertilizer granulator is a kind of granulating machine which can make the material into a specific ball shape. It adopts the new process design principle of wet continuous push rod granulation. When the raw materials enter the granulator, the raw materials are first made into semi-finished particles by the principle of stirring teeth, and then they are put into the rotary drum granulation part for secondary granulation. The pelletizing rate can reach 99% and the finished products are all round balls. Compared with other granulators, this new granulator not only improves the pelletizing rate, but also greatly improves the output of finished products. It is a good choice for new and old customers. Working principle : Use the high speed of rotation of mechanical blending force and the occurred air power, realize the process of the fine powder continuous being blended, granulated, balled, densified,thereby achieving the purpose of granulation. The shape of granule is spherical, and the size of the granule can be adjusted according to the mixing amount of materials and the main shaft speed, the lower the mixing amount, the higher the speed of rotation, the smaller the granule,and vice versa.

White High Pure 99% Pharma Raw Material Anti Seizure Medication Levetiracetam CAS102767-28-2 Description: Levetiraceta , m is a white crystalline powder chemical. The chemical name is (S)-α-ethyl-2-oxo-1-pyrrolidineacetamide, the molecular formula is C8H14N2O2, and the molecular weight is 170.20900. Levetiracetam is an antiepileptic drug, which is mainly used clinically for the additional treatment of partial seizures in adults and children over 4 years old with epilepsy., Levetiracetam is a pyrrolidone derivative whose chemical structure is not related to existing antiepileptic drugs. The exact mechanism of levetiracetam's antiepileptic effect is unknown. Protective effects observed with levetiracetam against generalized seizures secondary to focal seizures induced by pilocarpine and kainic acid, two chemical convulsants that mimic the complex parts associated with secondary generalized seizures in some individuals Characteristics of sex seizures. Levetiracetam has inhibitory effects on both the ignition process and the ignition state in the rat model of complex partial seizures. In vitro and in vivo experiments showed that levetiracetam inhibited hippocampal epileptiform burst discharges, suggesting that levetiracetam may selectively inhibit the supersynchrony of epileptiform burst discharges and the spread of seizures. At concentrations as high as 10 uM, levetiracetam has no affinity for several known receptors, such as benzodiazepines, GABA, glycine, NMDA, reuptake sites, and second messenger systems. In vitro studies have shown that levetiracetam has no effect on neuronal voltage-gated sodium channels or T-type calcium currents. Studies have shown that levetiracetam antagonizes the activity of negative regulators of GABA and glycine-gated currents in cultured neurons. A saturable and stereoselective neuronal binding site for levetiracetam was found in rat brain tissue. Application: (1) The (S)-enantiomer of the ethyl analogue of levetiracetam. used as an anticonvulsant (2) The (S)-enantiomer of Etiracetam (E932970) and the ethyl analog of levetiracetam (P500800). used as an anticonvulsant (3) A compound that inhibits pulse discharge without affecting the excitability of normal neurons (4) For the adjuvant treatment of partial seizures in adults and children aged 4 and above.

This week, we launched a hydraulic cartridge logic element benchmark SUN DKFS- XHN. This hydraulic logic element is a normally closed, balanced poppet, switching element. Pilot pressure at port 3 shifts the valve to the open position. Most of hydraulic cartridge valve manufacturers in Ningbo China do not have this model. One of our customers in Brazil checked with 5 hydraulic valve manufacturers in 2 months, but none of them have this logic element. He was very happily to finally find it at AAK. But for it is his first time to do business with AAK, he ordered only 5pcs first last June as the trial order. Today, we received his regular order of 1,000 pcs for this SUN model DKFS-XHN Normally closed, balanced poppet, pilot-to-open logic element. It is said that AAK E-DKFS-XHN has passed the testing in the past year, its quality, function and performance is equivalent to SUN DKFS-XHN. AAK hydraulic logic element 2 major advantages: 1. Manufacturing quality, function and performance benchmark SUN. 2. But the price is less than 70% of SUN. Technical parameters of AAK E-DKFS-XHN Hydraulic logic element: Max.Working Pressure: 350 bar (5000 psi) Flow Rating: 30 gpm/min (120L/min) Min. Pilot Pressure Required to Shift Valve: 20 psi (300 bar) Max. Valve Leakage at 110 SUS (24 cSt): 10 drops/min @5000 psi (0,7 cc/min @350 bar) Pilot Volume Displacement: 0.02 in³ (0,33 cc) Cavity: T-22A AAK hydraulic logic element, benchmarking SUN DKFS-XHN, you can also give it a try.

Cuenca is a senior purchaser of AGRIA company in Spain. The boss is very satisfied with his purchasing work. Two years ago, AGRIA company developed a hydraulic equipment, and there were complaints after sales for more than half a year. The main problem was that the starting force of the hydraulic system would be insufficient, which was caused by the increase of internal leakage of the hydraulic check valves in the equipment. After Cuenca contacted the original hydraulic check valve manufacturer, the manufacturer said that some hydraulic check valves may have deviation during assembly, and he was willing to replace the hydraulic check valves with large leakage with new ones. Cuenca thought it was completely solved after replacement, but what surprised him was that less than a year after the new hydraulic check valve was replaced, the same problem occurred again. The boss was very disappointed with his purchase of hydraulic check valves this time. The manufacturer of the original hydraulic check valves still said that except for replacing the hydraulic check valves, there is no other way. Cuenca began to worry that if the same problem happened a third time, it would be too shameless. To be safe, he began to look for a new supplier of hydraulic check valves and began to test samples. At the same time, he also wanted to know why the hydraulic check valves produced by the original manufacturer leaked. In this way, Cuenca contacted AAK hydraulic valve. After several rounds of communication with Cuenca, we learned the story between him and the original manufacturer of hydraulic check valves, and suggested him to send us the hydraulic check valves with problem and provide us the drawings of hydraulic check valves at the same time. AAK engineer disassembled the hydraulic check valves of the original manufacturer and found that there were wear marks on the sealing line on the surface of the poppet valve. When the pressure oil reversely enters the hydraulic check valve, the cone cannot strictly seal the oil and cause leakage, and some oil flows out of the oil inlet. After receiving AAK's analysis, Cuenca asked us to make 4 samples of hydraulic check valves according to his drawings. Our engineers designed a new hydraulic check valve according to the service frequency and working conditions of the equipment, replacing the cone valve with the ball valve. The cone valve is prone to fatigue creep deformation and wear after working for a long time, resulting in a gap between the valve sleeve and the cone, resulting in leakage. The outer circle of the ball valve can contact the inner taper ring line, and the connecting hole can be closed to reduce the leakage caused by wear. Cuenca was surprised that AAK dared to take the initiative to modify the drawings of their hydraulic check valves, and expected to see the sample performance of AAK hydraulic check valves. Two months later, AAK sent samples of the newly designed hydraulic check valves. A year later, Cuenca said that the hydraulic equipment equipped with AAK hydraulic check valves had no complaints about startup. He was glad that the original hydraulic check valve manufacturer replaced it again and again, which could only guarantee the service for half a year, but AAK solved the problem one time. In only 2 months, AAK helped solve the problem of leakage in the hydraulic check valves that plagued Cuenca for nearly 2 years. Cuenca would rather give up the original supplier who has cooperated for many years than choose AAK hydraulic check valves. AAK hydraulic check valve, valve spool design is unique and different, welcome to have a small try! https://www.aakindustry.com/info-detai , l/hydraulic-check-valves-aak165
