Product Introduction All toothed
rollers crusher on the market adopt mechanical
spring safety device, to adjust the discharging port, it will
always achieve by man with long wrench to change the length of the
spring or add spacers. But the dimension of four roll crusher is
big, it will need the operator to climb on the crusher to do those,
this takes time and isn\'t safe. Sometimes when the crusher is
stopped due to there have unbreakable materials inside it, we need
to enlarge the roll gap so that the unbreakable materials can be
discharged out. However, there are space limitations, and it takes
time and labor to do that, it is not convenient to do repair and
maintenance. To solve this
problem, our company combines the safety device and adjustment
device to be a Pneumatic-hydraulic cylinder on the basis of
HLPMG series roller crusher. Inject hydraulic oil into rod side,
and high pressure nitrogen, can change the rod position by add oil
or reduce oil in the chamber. Piston rod is connected with bearing
base with lever so when the piston rod move, the roller can aslo
move. And we can get exact roller gas by adjusting the oil
quantity. This realizes easy repairing and maintenance and that\'s
our HLPM7G, the 7th NEW ROLLER CRUSHER!!! HLPM7G the 7th
roller crusher has all advantages of HLPMG series: efficient,
energy-saving, environmental and intelligence. Mainly suitable for
materials of the compressive strength value ≤*0Mpa, particle
size ≤**0mm, such as coal, coal gangue, slag, carbon, etc. It
can directly break materials to *0mm or below (more than *0%). It
has the advantages of great capacity of crushing, small unit energy
consumption and wide application range. Mainly used in electric
power, mining, coal chemical industry and others. It is one of the
best choices for crushing coal for circulating fluidized bed boiler
in power plant, pulverized coal furnace, coking plant, iron-works,
etc.
Operating Principle Two motors drive rollers of
the first and second level in the opposite direction. When
materials comes into the first crushing level from the distributor.
interlaced teeth crush the materials from **0mm to *0mm and below.
Then, materials come into the second crushing level for further
crushing from *0mm to *0mm and below. Rollers teeth are crossed
with each other which can crush materials with effects such as
cutting, splitting, breaking, pulling, etc. Meanwhile, materials
rolled over and over during crushing so that the crusher can find
the most fragile position for crushing. Toothed rolls only crush
materials of bigger size, small size materials that meet the
requirement can discharge direct to avoid over-crushing.
Main Features 1. Single crusher still
has high output and the size is even. The size can be arbitrary
adjustable in the range of *0 to *5mm. 2. Air eddy offsets each
other, meanwhile, the leeway of the feeding and discharging hoppers
is approximately equal, which leads to no dust rising. Theres no
need for installing special dust removal
equipment. 3. The adopting of a special
kinematic principle makes the crusher no sticks and stop-up and no
particular moisture requirement of the materials. 4. The toothed plate is forked
tail type which adopts sliding lockers to fasten the plate and
achieves easy removal of it. 5. The design takes fully
advantages of pull crushing theory and kinetic energy principle to
reduce idle work. Thus, its energy assumption is *0%**0% of same
types ring hammer crusher. 6. Change lubricating oil
automatically to protect the bearing and prolong its usage
life. 7. No need for vibrating
screen. One crusher can replace several traditional crushing
production lines with the broken ratio *0:1. 8. Each toothed roller\'s
vibration frequency is different, but they cancel each other.
Vibration and noise greatly reduce (without damping platform), and
live load is 1.3 times of dead load with small impact on the
building. 9. Equipped with special open
device, the first and second door can be opened convenient. It is
easy to remove quick-wear parts. *0. Use sensor to do distance measure, numbers
on the dial displays the roller gap distance. Inject oil by manual
pump, or reduce oil by shut-off valve or lock, can adjust the
roller gas easily and remotely. In the chamber, the nitrogen
pressure inside the chamber can be adjusted at a certain range
which means the roller pressure is adjustable, and since piston
moving distance is long, the roller can move back far, this is most
suitable for large crushers.
