Roll crusher, appeared in 1806, is the most ancient crusher (jaw crusher), which is invented
by as English man thomas. Its roots can go back to the ancient treadmill, which
is the prototype of roll crusher. The working principle of treadmill is also the
working principle of roll crusher. The treadmill continues to improve in actual
production process, evolving to several types, such as the plain-roll crusher,
which is used in the metal mine industry; the rod-toothed crusher, which is used
in the coal industry and so on. However, the development of traditional roll
crusher is limited, making slow progress. In the 1980s, based on research result
of professor shaw in university krauss, krupp company and khd company in german
launched the high-pressure roll crusher. The high-pressure roll crusher adopts
the high-pressure crushing force, which crushes the material in the contact. The
impact in the roller reduces the relative sliding action between the material
and the roll surface. The high-pressure force from roll surface to the material
improves the working efficiency of crusher and reduces the wear rate of roll
surface, making the high pressure grinding roller move towards the
industrialization.
The machinery manufacturing methods of Hongxing roll
crusher and rod-teethed crusher has always been a mystery in machinery
manufacturing industry. Hongxing roll crusher has been awarded three national
patents. Now, let Hongxing experts share their patent technology with
us.
Unique roll crusher structure
First of all, driving system works like
this: two motors drive rollers through triangle belt transmission. The two rolls
force the ore particles between their rotating surface into the ever smaller gap
area, and it fractures from the compressive forces presented by the rotating
rolls.
Secondly, the granularity out of the equipment can be adjusted. The
particles are drawn into the gap between the rolls by their rotating motion, a
wedge block formed between the rolls and the particle, called adjusting device.
Adjustment bolts are fixed on the top of wedge block. When bolts pull wedge
block up, the wedge block push moving roll away from fixed roll, the gap become
bigger, and the discharging granularity become bigger. And vice versa.
Double roll crusher has teeth on the face of the roll, and it is designed
with high capacity. The connecting method about motor and speed reducer adopts
hydraulic coupler. The equipment is mounted with overloading protective device
to ensure operation. The gap width between the rolls can be changed by hydraulic
adjustment system. Centralized lubrication system, which can lubricate all
parts. Tooth design optimized.
With economic growing, a variety of metals
and non-metallic minerals, cement factories, buildings, gravel and metallurgical
industry has expanded their production scale; crushers--their processing
machines—play a very important role in the development, and have become
stanchion of the industry. It is expected that efficient free-pollution fuel and
machinery will have good development prospects in the future. To a certain
extent, reducing power consumption or improving system output can solve the
problems of low production and disorder operation in cement enterprises. Roll
crusher continually accelerate its development, adopt a simple, practical and
versatile mechanical hydraulic electrical protection system for crushing
materials of medium hardness in cement, metallurgy, chemicals, electricity, coal
and other industrial sectors, for example, it is used in coarse crushing or fine
crushing limestone, slag, coke, coal and other materials.
