Counter-flow cooler is an international popular new type cooler. It uses the principle of counter-flow cooling with high temperature and high humidity particles of material for cooling. Namely environmental air cooling vertically through the material layer, that first contact with the cold material. The hot hot air contact with hot material gradually. Wind direction is in contrast to the direction of material flow. So that the particle forward gradually cooling, which can avoid other cooler of the cold wind direct contact with high temperature granular material, and make the quenching of particle surface cracking. Because of the cold air from the bottom into the cooler in all directions, the wind area is large, the cold wind utilization rate is high, therefore, the cooling effect is remarkable, the machine is low energy consumption, easy operation, so the counter-flow cooler is superior to your previous vertical, horizontal updated products of cooler. Increase sieving equipment at the bottom of the cooler, which can remove unqualified particles and constitute a counter-flow cooling sieve machine.
Counter-flow cooling sieving machine is main four major components that cooling bin, body, linear vibrating screen and dust collector. Cooling bin include that closed air feeder, feeder, bin and the bin body. The body including frame slide valve discharge mechanism, discharge hopper. Linear vibrating screen includes sieve, sieve, vibrating motor. Dust collector including the cyclone dust collector, fan, pipes and bag filter.
From granulator suppress the particle from the cooler at the top of the closed feeder inlet into the wind. The ling tapered feeder, make the particle distribution, particle material from the top of the bin before and after, left, right, five roads into the bunker in the body. At the start, when the granular material gradually accumulation to contact on the material level, the motor on and start to work. Motor through the gear reducer and eccentric driving around nesting boxes do reciprocating motion, when the activity boxes and fixed box each sash overlaps, particle material from the cooling box into the sieve, sieve extension under the vibration motor driven, high frequency reciprocating motion, unqualified particles from under the sieve, sieve on qualified particles through the aggregate mouth, into the next procedure, complete cooling screening process. Cooling exhaust fan driven by wind in, after a cyclone dust collector, bag filter (optional) after discharging standard.
The principle of counter-flow cooling particles is to cool high temperature, high humidity. It can avoid cold and hot material in direct contact and quenching phenomenon, and also can prevent particles from the surface cracking. Meanwhile feeding using closed valve. Into the wind area is large, so the cooling effect is remarkable; After cooling the particle temperature is not higher than the room temperature of 5 ℃. The plunger reciprocating discharge mechanism, the smoothly move, reliable, small residual. Low energy consumption, easy operation. That adopted the octagon process feed structure and well configuration, improve the structure of the equipment, improve the shortcomings in the corners of the old series uneven stacking. Screening efficiency can reach to 99%.

Counter-flow cooling sieving machine is to press the pelletizer just out of high temperature, fragile particles, rapid cooling, removing water, screening, make its temperature near room temperature, moisture content down to ≤12%, particle harden and screening unqualified particles, called facilitate storage transportation of the final product.
