SFSP drop-shafted hammer mill

SFSP series drop-shafted hammer mill

Ordinary grinding can be performed, but also for fine crushing. Widely used in large and medium-sized feed mills, high quality feed production and alcohol plant, citric acid factory, food factory, etc.

Finished product granularity more fine and uniform: Φ3 mm sieve can reachΦ2 mm mesh fineness, Selects imported SKF high quality bearing, low operating temperature rise;

Compared with weight is lighter and fat content is higher, it greatly improves the sieving rate, yield than other shredder similar power increased by 15% ~ 20%; Discharging unobstructed, high efficiency.

The machine uses motor direct drive, scientific and reasonable hammer sieve clearance, crushing chamber adopts the secondary crushing technology.

1. This series Grinder can grind kinds of granules feed materials, like: corn, sorghum, wheats, beans,cottonseed meal, canola, etc.
2. It can apply to aquatic feed and special feed plants fine powder grinding, and also the fine powder processing of the medicine, and so on.
3. The motor is set on the same base with the rotor, direct drive.
4. Compact structure, quick and easy to change the seive.
5. It have the safety device on the operating door,The rotor is calibrated by strict dynamic balance.
6. Fine grinding, the seive mesh size Ф0.5mm-Ф3.0mm.

Performance Fetures

☑Grinding system is efficient and reasonable.
☑Super wide crushing, optimization or hammer arrangement, micro grinding is higher and efficient.
☑The hammer piece can have long service life.
☑Equipped with high precision dynamic balancing of rotor, small vibration, low noise.
☑Movable operating door and linkage type press screening mechanism, operation and maintenance is more convenient.
☑Equipped with a safety interlock device, to protect the personal safety.

FAQ

What are the maintenance precautions for the crusher?

1.Bearing lubrication: Our company's 90KW and above models are equipped with a circulating oil lubrication system and bearing stability monitoring as standard. Replace the 32# hydraulic oil 6 months after the first maintenance, and then replace it once a year;
2.Coupling: Check the coupling every month. Are the flat and serpentine springs worn? Hammer screen: Regularly inspect and promptly replace severely worn hammers and damaged screens.
3.Feeder: Clean iron debris, stones, etc. in a timely manner during each production shift.

Is this crusher suitable for crushing coarse and fine particle sizes? How to adjust?

1.The biggest difference in the design of Mufeng Intelligent's crusher is that the hammer-sieve gap can be adjusted arbitrarily between 2mm-12mm.
2.When the screen rotates between 0.8mm-1.5mm, the hammer-sieve gap is adjusted to 2mm-5mm. between;
3.When the screen mesh is selected to be 1.5mm-3mm or larger, the hammer screen gap is adjusted to 12mm.
4.However, other manufacturers only have two fixed options for the hammer and screen clearance of their crushers.

How long does it take for the hammer to be replaced? Is it easy to replace?

The replacement time of the hammer blade depends on the degree of wear of the hammer blade. During normal production, regularly switch the forward and reverse rotation of the pulverizer so that both ends of the hammer blade are evenly worn. When both ends are seriously worn, the hammer blade needs to be replaced in time, otherwise the output will drop rapidly. ; The unique hammer fixed structure of Mufeng Intelligent Crusher eliminates the need to remove the spacer sleeve when replacing the hammer blade. It is faster and easier to replace the hammer blade without a spacer sleeve.

What are the other factors that affect the efficiency of the crusher?

Factors that affect the output of the crusher include hammer wear, whether the screen is blocked, whether the current is adjusted to the closest to the rated current, whether the air pressure and air volume of the negative pressure air suction meet the requirements, etc. In order to ensure the best efficiency of the crusher, it is necessary to Frequently check the hammer and screen. The crusher is equipped with PID automatic control, equipped with a suitable negative pressure suction system, and frequently check whether the pulse bag is well ventilated.
