Multi-Deck High Frequency Screen

Main Features of the product:

A) Multi-feeding by stacking multiple screen boxes from 1 to 5 layers.
B) Vibration frequency is 24Hz; frequency conversion speed regulation and remote monitoring system can be configured according to user requirements.
C) Equipped with fine polyurethane screen, high opening rate, wear resistance, non-blocking hole and long service life.
D) The invention patented non-metallic shear spring has stable and reliable operation, low basic dynamic load and low noise.
E) Equipped with a feed box suitable for different materials screening, reasonable distribution to improve screening efficiency and reduce the impact of ore pulp on the screen surface; the screen  machine is equipped with a repeated pulping system, which significantly improves screening efficiency
F) The seal between the screen and the screen body to avoid the leakage of the upper part of the screen from the gap of the connection and affecting the yield.
G) Screening machine selection accessories: mineralizer, maintenance and repair platform, frequency conversion speed regulation and remote monitoring system.

Fabrication Feature 

A)The vibration system of the screen is fully enclosed vibration motor or vibrator, which is light in weight, reliable in operation, low in noise and small in maintenance;

B)The movement track of the screen machine can be circular or linear according to different screening requirements;

C)Vibration frequency of sieve machine is 16 ~ 50Hz; Amplitude 0.5 ~ 2mm;

D)The installation inclination of the screen surface is within the range of -5 ~ 25°, which shall be determined according to the screening requirements of different materials;

E)Patented polyurethane screen with high opening rate, wear resistance, easy to block, and long service life4000 hours, more than 15 times of the stainless steel wire mesh

F)The damping device of the utility model patent shortens the time of starting and stopping the sieve machine passing through the resonance zone, which plays a protective role on the shear spring and extends the service life of the shear spring.

G)Equipped with feeding boxes suitable for the screening of different materials, reasonably distributed to improve the screening efficiency and reduce the impact of materials on the screen surface at the feeding end;

H)the utility model patent shear spring seat plate, make the shear spring maintenance convenient, improve the safety performance of the whole machine, greatly shorten the spring replacement time, improve the screen machine can be used;

I)Patented non-metallic shear spring, with stable and reliable operation, small base dynamic load and low noise;

J)Spray system is provided for wet screening and pulping; The dry screen is equipped with fully enclosed dustproof cover, with maintenance access door on the side, easy to disassemble and good sealing effect, which can reduce environmental pollution;

K)The sealing design between the screen and the screen body effectively avoids the effect of the leakage of the screen on the yield;

L)Multi-layer space superposition parallel feeding system, increase the production capacity of the system, with the minimum floor area, the simplest system pipeline connection, the lowest engineering cost and maintenance workload, to achieve the maximum screening capacity and work efficiency.

M)Material selectionThe side plate adopts Q245R; The side plate protection material is stainless steel; The material of the sieve plate and the lamination of the sieve plate is polyurethane; The material of feeding trough and sieve bottom funnel is Q345.

N)All contact surfaces with materials are coated with polyurethane wear resistant layer.

Advantages

High separation efficiency, more than 80% on average.

1. Small unit area and large processing capacity.
2. The fine screen mesh is non-blinding and long using life, usually, the life achieves over 6 months.
3. The screen frames are sprayed with polyurethane  screen using life can be over 10 years, 
4. the overflow parts such as oversize and undersize hoppers are lined with high wear resistant rubber or polyurethane  materials.
5. Slurry-divider uses the split type cylinder-shaped design,
6. the slurry enters into the inner from the center and flows through the uniformly distributed chambers inside and outside the cylinders.
7.  Rubber suspension support springs are installed with good shock absorption effect
