The size of Polytrack® is 6/2,5-2,5, that means 2 grates of 2,5 modules each, 6 tracks per grate (width = 3 m and length = 12 m).
The cooler is equipped with a static grate at the kiln chute and with two mobile grates which consist of a total of 5 assembled modules 4 meters in width. The hammer crusher is located at the end of the grates.
One of the main advantages of this new type of cooler is that there is a separation between clinker transport and cooling system, there will be no influence of any transport system wear on the cooling efficiency which is one of the main problems with grate cooler of the old generation.
The clinker transport is ensured by 6 "tracks" which are located in the clinker bed and moving in the same direction as the clinker.
The cooling air is introduced by static plates with autogenous protection and they avoid any clinker dust chute into the cooling air chamber. There is no need for any hopper under the cooler casing and so no need for any transport system under the cooler. No slope for the grates is required thanks to the very good carriage efficiency.
The hydraulic system of the Polytrack is made of 6 units. Each track of the cooler has its unit. Each unit is made of one motor, a double pump, and 4 cylinders. Each track of each grate can be actuating separately with different speeds if necessary allowing high flexibility of the transport system and control of the clinker distribution on all the cooler width.
