1. Main features of the equipment:
Hui da SZLH508 high-grade pellet granulator is suppression of various kinds of granular feed host, it is suitable for large and medium-sized feed mills, 4-20 tons of grain production of material, it can be produced respectively with class 2 to 4 tons of powder feed mills.
The high grade granulator of huda SZLH508 is equipped with a variable frequency speed regulating motor for feeding, a strong magnetic security device and an overload protection device, an organic external discharge mechanism and a lubricating system for a pressurized oil pump.
Hui da SZLH508 high-grade pellet granulator has 30 2, 30 3, 4, 30, 30, 4.5 5, 30 30 6, 8, 30, 30 more than 10 kinds of aperture, adopt international advanced German gun drill, and the vacuum heat treatment furnace and added to the manufacturing process of alloy steel ring die, long service life, the material is smooth, high quality, can choose according to the needs of different users.
Hui da SZLH508 high-grade particles granulating machine adopts full stainless steel structure with large feed conditioning systems, (can be equipped with one layer, two layers, three layers of conditioning) adopts frequency control of motor speed control, speed adjustable, the feed rate of variable, in order to achieve the rated current and output. Conditioning cylinder composed of two assembled, length can be extended appropriately according to user demand, opened a door to repair watch cleaning, the axial jacket steam injection device, going into the 0.1 0.4 MPa steam drying by radial axial admission, make good contact with steam and material, improve the effect of quenched and tempered. At the same time also can add the mouth through the conditioning of grease to join right amount and the heated to 80-100 ℃ of grease or molasses, the oil pump pressurized into spray mist.
Optional ring die lifting device, using worm gear, worm drive, and pull out the guide rail, the hole in the sling with the hole in the ring to connect with bolts after the lifting.
The pressing room is composed of pressing mould, pressing roller, feeding scraper, cutting tool and die roller clearance adjustment screw. Feed through die cover and feeding scraper, the powder feed into two crushing zone, through the die and roller rotation, extrusion, gradually to feed into die hole, in the hole forming, and constantly to the extrusion die. Cut the cutting knife into the desired length, and finally the forming particles flow out of the machine.
The main drive adopts the high-precision gear transmission, the ring mode adopts the quick-discharge type, and the output is about 20% higher than the belt transmission type. The whole drive part (including the motor) selects the high quality bearings of Switzerland and Japan to ensure the transmission efficiency, stability and low noise. And the coupling adopts the international advanced level and other compensative snake type spring coupling, compact, safe and low fault.
Huda SZLH508 granule granulator has perfect security system: overload protection, security magnet, pressing door cover protection switch and external discharging four parts.
(1) when there is a foreign body into the pressing area or material flow is too large, between the roller and molding pressure than normal working pressure, spindle torque under more than normal torque which is passed to the safety pin shear force is more than the ultimate strength of itself, the safety pin broken, to rotate the spindle spline fitting, touch switch and downtime.
(2) the work to avoid the press room door open, due to the high speed rotating die cause unnecessary casualty accidents in life, is on the right side of the door cover ground bearing is equipped with a security trip switch, when open the door, the stroke switch control circuit, disconnect all of pelletizer pelletizer all stop running, or won't start, to ensure personal safety.
(3) when it needs to be closed as long as the pull handle, nesting nesting is to rotate the chute, all the material in the conditioning into the clear, and is not to enter indoor, which is mainly use in granulating machine commissioning before the normal work and too late to stop or to stop the error occurs when troubleshooting, temporarily is not enter indoor, can make the material after being normal push handle, nesting to reset the chute, can make the material returns to normal.
The high grade granulator of SZLH508 can be used to lubricate the lubricating system of the thin oil machine, and the electric oil pump presses the grease into the main shaft oil hole, and lubricates the roller bearing and the empty bearing.
The SZLH508 high grade granulator is equipped with all stainless steel cutting tool, with calibration on the tool bar. The outer surface of the blades shall not be less than 3 mm, so as to avoid the collision between the cutting knife and the ring mode.
Ii. Working process:
Water content is not more than 15% powder from the hopper into the feed of the twisted dragon, by frequency conversion motor to adjust speed, get the right material flow, the security guard magnet to remove mixed materials of medium magnetic impurities, then into the blender, quenched and tempered by mixing rod mixed with steam, if you need to add molasses or fat, also from the mixing drum to join together with steam conditioning, (oil content is generally not more than 3%, otherwise difficult to forming), after tempering temperature powder can reach 64-85 ℃, humidity up to 14-16%, and then through the chute, and finally into the crushing chamber to granulating.
Iii. Advantages of equipment
Huida SZLH508 high - grade granulator is an international latest technology low - fault model. The main standard parts are imported directly from abroad, and its shape, interior design and manufacturing quality are all in the 1990s, ensuring the life span of the ring die is 8000 to 10000 tons.
The material is homogenized and well prepared.
The continuous work is stable, the noise is 82 decibels.
Convenient operation and reliable sealing.
Stable rotation, shock absorption and vibration isolation.
High productivity and low labor intensity.
Adopt international advanced piping system and inlet pressure regulating valve.
Iv. Usage requirements:
In order to ensure continuous production, the buffer bucket volume on the granulating machine is not less than 3 cubic meters, so as to guarantee the continuous production of 10 minutes. The hopper bottom is fitted with a door for control.
To guarantee into the steam quality of quenched and tempered, the steam pipe should be installed steam separator, prevent condensation water from entering the conditioning device, and the relief valve should be installed, and to ensure the steam pressure of entering shoulds not be too big, and stability. The requirement for steam lamps is high temperature and low moisture content of supersaturated vapor.
The clearance of pressure roller should be controlled properly, the clearance is too small, the pressure roller and die wear are serious, the clearance is too large, and the output can be affected, even the grain can not be made, and the general clearance is between 0.05 and 0.3mm. Working status.
The equipment matching with the granulator should be matched in the production process.
