The feed cooler adopts the principle of counterflow cooling. The pellets sufficiently and evenly cooled. The machine adopts a unique sliding valve mechanism to discharge materials, and the operation is smooth and the discharge is smooth. Zhengzhou Fusmar Machinery is a professional feed cooler manufacturer. This article will mainly introduce the SZLH series of cooling machine.

New Type Cooling Machine

Fusmar counter flow cooler is a new type of cooler popular in the world. It uses the principle of counter current cooling to cool high temperature and high humidity pellets, that is, the ambient cold air passes vertically through the layer, first with the cold phase. The hot air heated in contact with the hot material and the direction of the wind flow is opposite to the direction of the flow.

So that the pellets gradually cooled in the forward direction, and the other coolers can prevent from directly contact with cold air and high-temperature pellets, thereby quenching the pellets. And then cracked surface of the particle. Since the cold air enters the cooling machine from the bottom in all directions, the air inlet area is large and the cold air utilization rate is high. Therefore, the cooling effect is remarkable, and the machine has low energy consumption and easy operation, so the counter flow cooler is excellent. Therefore, the counter flow cooler is an upgraded product that is superior to the previous vertical and horizontal coolers.

Application Scope Of Feed Cooler

Cooling the pellets is an indispensable process in the pelletization section. The counter flow cooler can cool the pellets from the feed pellet machine at a temperature of 70℃ to 90℃ to a temperature slightly above room temperature of 3℃ to 5℃ and can reduce to normal moisture (≤12.5%), which is convenient for pellets to transportation and storage.

The SKLH series of counter flow cooler is available in different models. It can adapt to feed mills of all sizes.

How To Work Of The Feed Cooler

Fusmar counter flow cooler mainly composed of rotary closed air feeder, air outlet top cover, rhomboid bulk material, cooling box body, upper and lower level positioner, deceleration brake motor, eccentric transmission spool-type discharge mechanism, fixed the frame adjusting device, the collecting hopper, the frame, and then composed of the same suction system.

The working process is a high-temperature and high-humidity granular material. Which is discharged from the feed pellet machine and is uniformly stacked in a cooling box through a rotary conical bulker. And the cold air is slide-type from the lower side of the cooling box. The bottom of the discharge mechanism and the upper part of the collecting hopper enter the cooler in all directions. Pass through the material layer to exchange heat with the moist heat particles, and then suck out through the suction system. So that the pellets can cool.

The position of the upper and lower levelers control the cooling time. When the granular material layer reaches the upper level, the motor starts to discharge. When the granular layer is lower than the lower level, the motor stops discharging. After the motor stops, the travel switch controlled the relative position between the movable frame. And then the fixed frame in the spool type discharge mechanism through the brake motor. Which ensures that no material leaked after stopping the discharge. The sliding valve type discharging mechanism installed at the bottom of the box body, and the deceleration brake motor reciprocated the movable frame through the eccentric mechanism. The relative position between the movable frame and the fixed frame is changed so that the granular material is discharged out of the box body. And then concentrated discharge from the collecting hopper.

Counter Flow Cooler Equipment Features

  1. The mixing time is 90s, the mixing is uniform, and the cv is not more than 5%.
  2. The distribution of various materials after mixing is uniform, and the material does not decompose.
  3. The filling can change into a wide range, and the filling coefficient can vary from 0.1 to 0.8. Which can use for mixing various proportions and granular materials in many fields.
  4. Select the full-length door structure, the discharge is rapid, and there is no residue.

Why Choose The Counter Flow Cooler

Zhengzhou Fusmar Machinery developed the feed pellet cooler is a new generation of SKLH series counterflow cooling equipment. For many years of feed machinery production and sales experience, combined with the current international advanced cooling technology. It is mainly used for the cooling of high-temperature pellets after granulation. The feed pellet cooling machine adopts the principle of counterflow cooling. The pellet cooling is sufficient and uniform, and the unique sliding valve mechanism discharges the material. And then the operation is smooth and the discharge is smooth. The cooled pellet temperature is not higher than room temperature + 3-5℃. Large output, good cooling effect, the high degree of automation, low noise, and low maintenance. This model is widely used in advanced countries and is an advanced replacement cooling device.

The counter flow cooler is mainly suitable for the cooling of pellet feed after the feed section of the feed pellet mill. The high-temperature pellets from the feeder are cooled to a temperature slightly above room temperature in a short period. To ensure continuous production of the entire feed pellet production line. Easy to storage and transportation of the feed pellets.
