LS type screw conveyor

Screw conveyor introduction

1. Characteristics and application range of LS type screw conveyor:

LS type screw conveyor (hereinafter referred to as screw machine) has novel structure and advanced technical indexes. The head and tail bearings are moved to the outside of the shell. The middle suspension bearing adopts two structures of rolling and moving interchangeability, and all have dustproof sealing devices. The discharge end is provided with a cleaning device, which has low noise, strong adaptability, convenient operation and maintenance, and flexible arrangement of inlet and outlet.

Application range:

Screw machines are widely used in various industrial sectors, such as building materials, electric power, chemical, metallurgy, aluminum-magnesium, coal, machinery, light industry, food and food industries; used at horizontal or less than 20 ° inclination, conveying powder, granular and Small fast materials, such as cement, coal powder, grain, fertilizer, ash, sand, etc., the material temperature is below 200 °C.

It is not advisable for the screw machine to transport materials that are prone to deterioration, viscous and easy to agglomerate, because these materials will adhere to the spiral during transport and will rotate without moving forward or forming a build-up of material at the sling bearing. And the screw machine does not work properly.

LS type screw machine spiral diameter from 100 mm to 800 mm, there are nine rules, length from 4 meters to 70 meters, every 0.5 meters first gear, the selection should meet the standard nominal length, special needs can be selected in the section Will be submitted separately.

ccording to the rotary drive mode, there are two types:

C1 method - single-end drive when the length of the screw is less than 35m.

C2 method - double-end drive when the screw machine is larger than 35m.

According to the type of intermediate bearing of the screw machine:

M1-for the rolling suspension bearing, it adopts 80,000-type sealed bearing. The shaft cover has a dust-proof sealing structure. It is often used in areas where it is difficult to refuel, no oil or oil is polluting the material, the sealing effect is good, the hanging bearing has a long service life, and the output material is Temperature ≤80°C (may not be specified when ordering)

M2-It is a sliding suspension bearing with dustproof sealing device. It is usually used to transport materials with high temperature (>80°C) or to transport liquid materials.

Packaging logistics

Q:What is the reason for the small amplitude of GZV electromagnetic vibration feeder?

A: The silo pressure in the feeding system is too high. The solution is to make a chute under the silo to excess the material to the feeder chute and reduce the pressure of the silo pressure on the feeder.

B: The air gap of electromagnetic vibration feeder may change during transportation. Release the two screws that fix the core and adjust the air gap between the core and armature to about 

Q:Solution to burnout of drive motor of screw feeder

A: There are hard or small iron blocks mixed in the materials transported by the screw feeder, the cutter is stuck, the electric current increases sharply, and the motor is burned. The treatment method is to avoid the small iron blocks entering and to make the cutter and the casing adhere to certain voids.

B: If the material is too large, the motor will be heated and burned. The treatment method is to feed uniformly and send the material to the end when the machine stops.

Q:Solution to High Temperature of Suspension Bearing of Spiral Feeder

A: Improper azimuth installation, the treatment is to adjust the azimuth of suspension bearings.

B : Abnormal friction occurs when solid bulk materials are mixed into the machine. The treatment method is to tidy up foreign bodies and test run them to normal operation.

Q:Solution of Vibrating Screen Fault

1. The screening effect is not good. The following aspects should be checked and maintained.
(1) Blockage of screen hole or damage of screen surface.
(2) The moisture content of raw coal is too high.
(3) Screening feed is uneven.
(4) The material on the screen is too thick.
(5) The screen is not tight.
(6) Stop screening, clean screen or replace screen surface.
(7) The inclination angle of the shaker can be adjusted.
(8) Adjusting the feeding quantity.
(9) Reduce the amount of feed.
(10) Tighten the screen

2. Screen speed is not enough to drive belt loose should be checked and maintained from the following aspects.
(1) Bearing oil shortage.
(2) The bearing has dirt.
(3) too much oil is injected into bearings or the quality of oil does not meet the requirements.
(4) Bearing wear.
(5) Oil injection.
(6) Clean the bearing, replace the sealing ring and check the sealing device.
(7) Check the condition of oil injection.
(8) Replacement of bearings.
