120,000 tons of compound fertilizer production line

Release time:[2017-11-24 11:24:56]    Browser:5772second

  The production line is divided into eight processes: ingredients, mixed crushing, granulation, drying, cooling, screening, application and packaging.

  Process characteristics

  Mature production technology, stable equipment, high production efficiency.

  The investment cost is low, the production effect is good, the operation maintenance is convenient, at the same time is advantageous to the production line the second production redevelopment.

  It is widely used in the production of high, medium and low concentration compound fertilizer.

  The products of this process are in conformity with gb15063-2001 inorganic compound fertilizer national standard requirements. The discharge of waste gas and waste water is in line with the national quality requirements.

  Description of production process flow

  MAP, DAP, urea, ammonium sulfate, potassium sulfate, calcium superphosphate and other N, P, K of energy-saving materials and binder after measurement (granules raw material need to use crusher to crush), and then in the process of mixing, mixing evenly conveying to the granulator.

  After granulation, the particles have been formed, but the particles are too high to meet the requirements of the uniform packing speed. The material is delivered to the rotary dryer for drying.

  The temperature of the dry particles was too high, then the cooling process was carried out by a rotary cooling machine, which further improved the high particle strength and reduced moisture.

  After cooling, the particles have been sifted, sifted and sifted large particles and fine powder to obtain the finished product. The granulator is returned to the granulator and the granule is returned to the granule.

  Anticaking agent (or anticaking powder) according to certain proportion to heat melts, use of metering pump pressure, nozzle spray to the particle surface, used to form a layer of thin film, prevent fertilizer to prevent caking exposed to air.

  The coated particles are transported to the automatic quantitative packing scale for packaging.
