Do You Know What are the Main Technical Requirements of Conveyor Roller

How much do you know what are the main technical requirements of conveyor roller? Today, PK Machinery will introduce you this kind of knowledge from 5 aspects.

1.Conveyor roller cylindrical radial circular runout

In order to guarantee the belt conveyor run smoothly, it is necessary to make strict specifications on roller radial circular runout, otherwise it will cause conveyor belt vibration, increase conveyor belt running resistance and consume more power due to its higher value. Therefore, this is an important technology index for roller.

 

2.Rotational resistance after installation of conveyor roller

Excessive roller rotational resistance will cause conveyor roller damage in advance and conveyor belt wears rapidly, it will also cause the increasing of the driving power, so this is another important technical index for roller.

3.Waterproof, dustproof, sealing performance of conveyor roller

The service life of roller depends on its sealing performance to a great extent, good seal performance can prevent dirt and moisture entering into roller bearing roller way effectively. In order to improve its service life, we must develop better way of waterproof, dustproof, sealing performance.

 

4.Roller axial carrying capacity

Generally, roller bears the roll force for only one direction, therefore, we must ensure normal operation under axial load of roller.

5. Service life of conveyor roller

This is a comprehensive index which involving the scientific rationality of structure design, the manufacturing quality of roller, bearing selection, the choice of grease and grease filling and sealing effect etc.

 

Why will Belt Conveyor Motorized Pulley Get Rusty

Why will Belt Conveyor Motorized Pulley Get Rusty

Motorized Pulley plays an important role during operating belt coveyor. It is source of power and the belt conveyor cannot operate without it. Today, PK Machinery will list some reasons why motorized pulley of belt conveyor will rust.

During the operation process of belt conveyor, it will occur some problems due to incorrect method of using or wear and tear, therefore, we need to know some knowledge in order to ensure the normal operation. Here PK Machinery will list some reasons why motorized pulley of belt conveyor will rust:

1. Electroplating time is not enough, it dues to the problem of process flow;

2. Air liquidity of the location where motorized pulley stores is not good, or the location is wet, it is may due to the large difference in temperature;

3. If the package sealing breaks, the motorized pulley may oxidate and get rusty;

4. The most important point is that before electroplating, the dirt on motorized pulley surface is not being cleaned well, it is also one of the reasons why the motorized pulley will get rusty.

1) Open cover and fixed cover are manufactured with the galvanized steel plate or the colorized coating steel plate. Generally ,there will be 1 piece of open cover and 7 pieces of fixed covers installed every 8 pieces covers, the 2 kinds covers also can be installed side by side alternately ( it also can be matched according to customer’s requirement). At first, fasten the fixed conveyor with drilling rivets and based on the line which is upward 30mm from the top of Z type steel, fix a mounting hole every 450mm, every piece of cover overlaps 2 wave crests. Open cover overlaps above the fixed covers in order to open conveniently.

 

2) The Z type steel or the connection angle iron which is the main support frame of the conveyor cover, the length is equal to the length of the installed conveyor cover

The Z type steel or the connection angle iron is welded on the channel steel or the little stiffening angle iron on both sides of the conveyor

3) Install the covers (fixed covers) from one side to another side along the conveyor, during installation, people are not allowed to stand on the covers and no hard beating and hitting is allowed.

4) Mount the fixed covers on the Z type steel with the drilling rivet. The mounting points are not less than 4 on every piece.

5) 1 piece of observation window cover could be installed every 10 pieces for convenient checking and inspecting. It is decided by users.

6) Salient point cover is only used for the salient points of the convex-concave of the conveyor. Deviation switch cover is only used for covering the deviation switch. These 2 kinds covers also can overlap the fixed covers.

 

4. Note

1) During the installation, please handle the anti-rain cover carefully and avoid scratching.

2) After installing the accessories, please clean the surface and paint the scratched points again.

1) installation of handle

After overlapping the open cover and fixed cover, based on the center line of the cover, the location upward 250mm is the center line used for installing the handle (it can be adjustable according to height of the conveyor support frame). Put the handle straightly and drilling a 4－Φ5 hole, then fasten with the rivets.

2) installation of hinge

Adjust one side of the cover up higher from the top of the Z type steel (angle iron) 5mm, inward 140mm from the front and back sides of the cover, and upward 27mm is the location of the hinge, then drill holes Φ5 and fasten with the rivet. Others holes are also fastened with the rivets. 

3) installation of the lock catch

After installing the hinge, on the other side of the cover, inward 185mm from front and back sides of the cover, then based on the bottom, upward 36mm and 77mm , drill holes Φ5 and fasten the lock with the rivet, next keeping the lock locking( clamp status), and then putting the lock nose on the Z type steel straightly and drilling hole to fasten.

4) installation of the open cover

Overlap the open cover on the bilateral fixed covers. The overlapped length should be the length of 2 pitches of waves, then put the other side of the hinge appressed on the angle iron and drill hole 4－Φ5 with the rivet fastened.

How to Install Belt Conveyor Cover Support Frame

How to Install Belt Conveyor Cover Support Frame

‪‎Conveyor‬ ‪‎rainproof‬ ‪‎cover‬ plays an important role in ‪‎belt‬ conveyor. It can protect belt and materials at same time. This article will introduce how to install the support frame of conveyor rainproof cover.

Belt conveyor cover is applicable to power plant, cement plant, mines and other major factories which is waterproof, dustproof and windproof, it plays a great role in reducing the loss during the process of conveying goods ,making the conveyor belt more safe and reliable in operation and purifying the environment.
