Particle shape advantages of VC series cone crusher
In the whole working process of the cone crushing chamber, the more often the extrusion crushing occurs, the lower
the content of elongated and flaky particles in the crushed product is. Therefore, increasing the rotation speed of the
eccentric shaft or the eccentric body can improve the particle shape of the crushed product to some extent.
The VC series multi-cylinder hydraulic cone crushing chamber from NFLG has a unique rolling bearing design,
which not only makes the internal rolling element a permanent part and have a higher rotation speed, but also make
moving cone get a higher speed when it collides with the material and the production capacity and the yield of
materials higher, greatly improving the particle shape of finished products.

YS series circular vibrating screen
YS series standard screening machine adopts the current most advanced design concept in the world and is suitable for various
screening operations such as medium and fine screening. This inclined circular vibrating screen is an ideal screening machine
for treatment of materials after primary and secondary crushing. It can be used to screen the final finished materials. With the
advantages of large processing capacity, high screening efficiency and stable quality, and good anti-blocking effect, it's widely
used in industries such as sand and gravel aggregates, metal mines, coal, hydropower, and use of renewable resources.
30
Characteristics of YS series circular vibrating screen
Stable and reliable excitation source
The vibration exciter is standard equipment for the YS series
vibrating screen. Through adjusting the number of clump weights,
different excitation force requirements of various specifications
of vibrating screens can be met.
Longer bearing service life
Compared with the shaft eccentric duplex bearing design, 4 sets
of bearings can provide higher load and longer service life, and the
excitation force generated by the eccentric block passes through
the center of the thickness of the side plate, and the force
condition of the side plate is more ideal.
Convenient amplitude adjustment
By increasing or decreasing the number of clump weights, the
excitation force can be changed, and the amplitude of the
screening machine can be easily adjusted according to the site
conditions.
Grease lubrication system
Grease lubrication, special labyrinth design, simple and reliable, no risk
of thin oil leakage.
Faster and more convenient maintenance:
The vibration exciter is integrally installed in the inner hole of the side
plate, saving the trouble of replacing a single bearing, and the overall
disassembly and installation, replacement and maintenance are
convenient and fast.
The screening machine is of a frame structure, with high integral
rigidity and strength and durability.
The screen frame is riveted with Hack rivets, and the whole side
plate has no welding spots to avoid the hidden danger of cracking
caused by welding stress.
31 Efficient power transmission
The drive and the vibration exciter are connected
by universal coupling. It only transmits torque and
fails to transmit axial force, so that the screen
machine runs more stably and has a longer
service life.
The V-belt doesn't participate in vibration, has a constant
length and a longer life.
The motor drives the bearing block through the V-belt, and
the universal coupling flexible drive screen machine, it can
more protect the motor from brute force impact than that
the motor directly drives or drives screening machine through
the V-belt.
Excellent vibration isolation system
The maximum impact load is reduced by 50%, the screening
machine starts and stops very stably, and the maximum
amplitude of start and stop is reduced by 50%.
Noise reduction by 20%
No-load noise is only 73 decibels (national standard:
90 decibels), thus greatly improving the environmental
performance of the complete machine.
Excellent design of amplitude and frequency ensures
the best screening effect.
32

High-strength side plate, extending its service life; Fastening structure and durability;
Reinforcing plate of reinforced driving side plate; The axle power box with three-ply
wood structure expands the area of maximum stress; The corner is right-angled,
making it stronger.
Low maintenance cost, long service life;
The patented drive end lubrication system reduces bearing
lubrication obstacles, decreases bearing temperature and
prolongs bearing service life.
Patented gear guard plate facilitates lubrication, effectively
decreases bearing temperature and prolongs bearing life.
Unique design of excitation structure makes the amplitude
of screen box stable and the running of screening machine
smooth.
Chromium-nickel alloy gears have good materials and good
tooth profile, which are conducive to smooth operation and
prolonging service life. There is a unique labyrinth seal in the
bearing end cover, and the non-contact rotation enhances
the usage effectiveness and service life of the seal. The
design of bearing hub cone makes the bearing installation
convenient and quick and replacement of bearing easy.
Innovative elliptical track
The design of the elliptical track is to produce precise stones more efficiently. The design
combines the circular track and the linear track to form a unique elliptical track, which not
only has the anti-clogging and screening characteristics of the circular track, but also has
the characteristics of linear motion transmission.
Characteristics of NTH1860-3 horizontal screen
Gear drive
The core design is a three-axis excitation structure located in the
center of the screen box. The gear-driven vibration device is more
sturdy and durable after improvement. With convenient adjustment,
the stroke can be fine-tuned.
34
Fine tuning
Another advantage of the elliptical track is that the length and angle of the motion track
can be adjusted to adapt to various production requirements. The closer the vibration
direction angle is to the vertical, the more accurate the fine material screening. The longer
the travel, the faster the coarse material moves forward Convenient adjustment and operation.

37 NHS fine powder separator
The NHS fine powder separator is a centrifugal air classifier with a simple structure. The efficient
classification of fine powder is realized by using the wind force generated by centrifugal force. At
the time of classification, the raw material rises from the lower part of the separator by the airflow,
and then the fine powder is separated under the action of the rotary classification board. To improve
the classification efficiency, the dispersing cone and air circulation port are originally designed on
the machine. It is mainly used to separate coarse powder (above 45μm) and fine powder (below
45μm) in stone powder after production of sand and gravel aggregates.
Characteristics
1. High classification efficiency.
2. Environmental protective and pollution-free, closed circuit design, environmental protection and
no dust flying.

secondary air drying. (custom-designed)
Example of importing of NHS fine powder separator to
V7 dry-type sand making equipment
NHS can be imported to V7 dry-type sand making equipment to separate coarse stone powder (above
45μm) and fine stone powder (below 45μm) in stone powder. Produce finished sand with the same FM,
import NHS to maximum recovery of 12% of the coarse stone powder to improve the sand rate and
output. The fine stone powder (below 45μm) separated by NHS depends on the raw material. Some
fine stone powders can be used to replace mineral powder, fly ash, etc.
