GZL series fish feed pellet making machine
Descriptions:
Absorbed foreign advanced technique of powder granulator. improved and heightened on the basis of foreign technique, this dry-type granulator is developed by factory
it has more reasonable and compact structure, supply technological processes, easy operation and better performance.
powder materials can be made into even granules customer needs without adding any bonding anent when they run through the machine.
as density of granules are larger, no any afterward process is needed so as to reduces technological process, reduce granulation cost and powder pollution and improve labor environment as well.
Features:
Making granules from dry power directly without any bonding agent and to carry out thr2nd heating and drying.
The strength of granule can be adjusted by pressure of rollers so as to control strength of granule.
Sand-shaped irregular granules are produced.
Large productive capability due to continuous production, high degree of automation to suit automatic production.
Application:
Except those dangerous materials that are subject to explosion due to crushing and rubbing, most part of dry power materials can be directly granulated by this machine can also be suited for granulation of heat sensitive materials
Flow chart:
Principle:
1.vertical feed set after weight measured, powder materials are sent laterally by the vibration hopper to the main feeder, deaerated by the stirring screw of the main feeder, pre-pressed and pushed into the are pressed into dense sheet while they run through rollers.
2.Under the function of elastic recovery after rollers, they’ll be separated from rollers and drop down ,and fewer sheet not dropped will be scrapped off by the blade.
3.Stripe grooves evenly distributed on the surface of rollers can prevent sliding when powder materials are fed into rollers.
4.After crushed and granulated, they’ll pass through the vibration sieve to be graded, and granules which meet requirement can be obtained.
5.Powder after the sieve will return to the vibration hopper to be granulated circularly.
6.Horizontal feed set except feed and installation style of rollers being something different with that of vertical feed set, the operation principle of them are completely identical.
7.For horizontal feed set, powder materials from the vibration hopper are stirred and edareated, then they’ll be sent into that vertical feed set .

Note:
1,the output of rolled tablet is calculated in accordance with that the density of sheet is 1500kg/m3andthe revolution of rill is 20rpm. 2 and finished products to compute & runners. general 50% calculation
2 The output of finished product is calculated in accordance with that the granulating ratio is 50%
3.The size of finished product can be changed in rather wide range by adjusting the aperture of sieve plate of crusher and granulator .
4The actual operated power of main machine will be 70%of motor rated power.
5.The revolution of roll can be changed through change retio of and reducer.
