Screening Machine Series

Fertilizer Screening machine Series refers to a range of equipment used in the fertilizer production process to separate and classify different-sized particles of fertilizer materials. These machines play a crucial role in ensuring the quality and uniformity of the final fertilizer product by removing oversized or undersized particles and impurities. Here are some common types of fertilizer screening machines:

  1. Vibrating Screen: The vibrating screen is a commonly used screening machine that utilizes vibrating screens or meshes to separate materials based on their particle size. The vibrating motion of the screens helps to efficiently separate oversized particles and fines from the desired-sized particles.
  2. Rotary Drum Screen: The rotary drum screen, also known as a trommel screen, consists of a rotating cylindrical drum with perforated plates or screens. As the drum rotates, the fertilizer materials are fed into the drum and sorted by size. The smaller particles pass through the screens, while the larger particles are discharged at the end of the drum.
  3. Linear Vibrating Screen: The linear vibrating screen uses linear motion to separate materials. It is characterized by its high screening efficiency and large processing capacity. The screen deck is equipped with multiple layers of screens, allowing for precise separation of different-sized particles.
  4. Rotary Sifter: The rotary sifter, also known as a centrifugal sifter or rotary sieve, utilizes centrifugal force to separate and classify materials. The fertilizer materials are fed into the rotating cylindrical screen, and the centrifugal force throws the particles against the screen, separating them based on size.

These fertilizer screening machines are available in various sizes and configurations to accommodate different production requirements. They can be used individually or integrated into a complete fertilizer production line. The selection of the appropriate screening machine depends on factors such as the desired particle size range, processing capacity, and specific production needs.

Regular maintenance and cleaning of the screening machines are essential to ensure optimal performance and prevent clogging or blockage. The screens or meshes should be inspected regularly and replaced when necessary to maintain accurate screening results and maximize efficiency in the fertilizer production process.

MingChuan Fertilizer MachineryRotary Screening Machine

The rotary screening machine is a new type of self-cleaning screen special equipment after the electric vibrating screener and the ordinary network type roller screen produced by the domestic companies.It is widely applicable to sieving of various solid materials with particle size less than 300mm.It has many characteristics such as high screening efficiency,low noise,small amount of dust,long service life,less maintenance,and its screening capacity is 1t/h-20t/h.

Performance characteristics

  • 1.High screening efficiency.Because the equipment has a plate cleaning mechanism, it can never block the screen, thus improving the screening efficiency of the equipment.
  • 2.Good working environment.The entire screening mechanism is designed in the sealed dust cover, completely eliminating the dust flying phenomenon in the screening and improving the working environment.
  • 3.Low noise of the equipment.During operation, the noise generated by the material and the rotating screen is completely isolated by the sealed dust cover, which reduces equipment noise.
  • 4.Convenient maintenance.The equipment seals the equipment observation window on both sides of the dust cover, and the staff can observe the operation of the equipment at any time during work.
  • 5.Long service life.The equipment screen is composed of several annular flat steels, and its cross-sectional area is much larger than the screen cross-sectional area of other separation equipment screens.

Working principle

The self-clearing cage drum screening machine performs reasonable rotation of the equipment center separation cylinder through the gearbox type deceleration system. The center separation cylinder is a screen composed of several annular flat steel rings. The center separation cylinder is installed with the ground plane. In the inclined state, the material enters the cylinder net from the upper end of the central separation cylinder during the working process. During the rotation of the separation cylinder, the fine material is separated from the top to the bottom through the screen interval composed of the annular flat steel, and the coarse material is separated from the lower end of the separation cylinder. Drain into the pulverizer.

The device is provided with a plate type automatic cleaning mechanism. During the separation process, the screen body is continuously “combed” by the cleaning mechanism through the relative movement of the cleaning mechanism and the sieve body, so that the sieve body is always cleaned throughout the working process. It will not affect the screening efficiency due to the clogging of the screen.

The vibration screen machine adopts tube type eccentric shaft vibration exciter and partial block to adjust the swing. The material screening flow line is long, various screening size. It has the advantages of reliable structure, strong exciting force, high screening efficiency, small vibration noise, durable, easy maintenance and safety in use. The vibration screen machine is widely used in organic fertilizer, compound fertilizer, mining, building materials, transportation, energy and chemical industry.It consists of a screening box, a vibrator, a suspension (or support) device and an electric motor.

Working Principle

The vibrating screening mesh is operated by the reciprocating rotary vibration which is generated by the vibrator excitation. The upper rotating heavy hammer of the vibrator causes the screen plane to whirling vibration, while the lower rotating heavy hammer causes the sieve surface to produce a conical rotary vibration, and the combined effect of the rotating heavy hammer causes the screen surface to produce the complex rotary vibration. The vibration trajectory is a complex space curve.

The curve is projected into a circle on the horizontal plane, and the projection on the vertical plane is an ellipse. By adjusting the exciting force of the upper and lower heavy hammer, the amplitude can be changed. While adjusting the space phase angle of the upper and lower heavy hammer, the curve shape of the screen surface movement track can be changed, and the movement track of the material on the screen surface can be changed
