Embodiment 1

[0019] Example 1 (low metering)

[0020] It is composed of urea and potassium sulfate, 1 kg is 1 part, 44 kg of urea, 8 kg of potassium sulfate, 48 kg of fluorspar powder; the content of nitrogen is 20%, and the content of potassium is 4%.

[0021] When making, use a metering pump to add and mix urea and potassium sulfate in proportion, pulverize them through a pulverizer, put them into a mixer and stir them fully, and then press them mechanically to make granules with a particle size of 3-5mm, and remove them by sieving. Particles and powders smaller than 3mm are measured and packaged, and stored in warehouses; particles and powders with particle sizes smaller than 3mm are sieved and crushed, fully stirred, and granulated by machinery, such as figure 1 shown.

Embodiment 2

[0022] Example 2 (medium dose)

[0023] It is composed of urea and potassium sulfate, with 1kg as one part, 61kg of urea, 24kg of potassium sulfate, and 15kg of fluorspar; the content of nitrogen is 28%, and the content of potassium is 12%.

[0024] During production, use a metering pump to add and mix urea, potassium sulfate and fluorspar in proportion, pulverize through a pulverizer, put them into a mixer and stir them fully, and then press them mechanically to make particles with a particle size of 3-5mm, and pass through a sieve Particles and powders with a particle size of less than 3mm are separated and removed, measured and packaged, and stored in a warehouse; particles and powders with a particle size of less than 3mm are sieved and then pulverized and fully stirred, and then granulated by machinery, such as figure 1 shown.

Embodiment 3

[0025] Example 3 (high metering)

[0026] It is composed of urea and potassium sulfate, with 1 kg as one part, 78 kg of urea, 20 kg of potassium sulfate, and 2 kg of fluorspar powder; the content of nitrogen is 36%, and the content of potassium is 10%.

[0027] When making, use a metering pump to add and mix urea, potassium sulfate and fluorspar powder in proportion, pulverize through a pulverizer, put them into a mixer and stir them fully, and then press them mechanically to make granules with a particle size of 3-5mm, and pass through sieving Remove particles and powders with a particle size of less than 3mm, measure and pack them, and store them in a warehouse; sieve the particles and powders with a particle size of less than 3mm, crush them and mix them thoroughly, and press them mechanically, such as figure 1 shown.

Abstract

The present invention is potassium reinforced urea and its production process. The production process includes mixing urea with potassium sulfate or potassium chloride, and at least one of ammonium chloride, ammonium sulfate and ammonium nitrate with metering pump, crushing in crusher, stirring, pelletizing of 3-5 mm size grain, sieving to eliminate grain below 3 mm and powder, packing and storing. The addition of ammonium chloride, ammonium sulfate or ammonium nitrate as fast acting nitrogen source results in fast dressing effect. The present invention has fast and long fertilizing effect.

Description

technical field [0001] The utility model relates to a mixed fertilizer, in particular to a potassium-added efficiency-enhancing urea and a production method thereof. Background technique [0002] At present, the urea sold in the market is all urea with a single content, and its nitrogen content is about 46%, and most of the urea is used as top dressing. Since urea has a single nutrient, crops, plants, etc. cannot absorb it in a balanced manner, thus reducing the absorption efficiency of crops, plants, etc. A single nutrient will also cause a lack of other macronutrients such as crops and plants. After application, crops and plants will be prone to lodging, leafy stems are thin, grains are not plump, and diseases are prone to occur. Contents of the invention [0003] The main purpose of the present invention is to solve the above-mentioned problem of single nutrient content of urea, and provide a kind of potassium-added and synergistic urea with fast fertilizer effect and...
