Installation and Notes of Belt Conveyor Anti-rain Cover

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.

Installation of Belt Conveyor Cover Support Frame

 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 .

As the main support frame of the conveyor cover, the length of Z type steel or the connection angle iron is equal to the length of the installed conveyor cover. Please weld the Z type steel or the connection angle iron on the channel steel or the little stiffening angle iron on both sides of the belt conveyor. If need the stiffening angle iron, at first, weld the stiffening angle iron on both sides of the conveyor, then weld the Z type steel or the connection angle iron on the stiffening angle iron, detailed steps are as following:
 1) first weld the little stiffening angle iron ∟40*40*100*4(just for reference, it also can be indicated by users) every 1.5m or 2 m on both sides of the belt conveyor ( eudipleural ). The height from the intermediate frame to the top of little stiffening angle iron should ≥50mm ( it also can be decided by users).
2) Then weld the Z type steel 30*50*30*(2.0~3.0),( just for reference, it also can be replace by angle iron) and fix it on both sides of the intermediate frame top, the inner size should be 10-20mm bigger than outside size of intermediate frame.
3) After being welded please remove welding slag then paint.

How to Prolong the Lifespan of Vibration Motor

1. Make sure the wiring and insulation work of vibration motor is well done in order to prevent the lack of phase and short circuit .
2. Anchor bolt reinforcement work should be done frequently, take necessary prevention measures, such as using a double nut fastening to ensure vibration motor base and the floor contact well.
3. Attach great importance to the cover sealing of vibration motor, the dust inside the protection cover should be cleaned up frequently.
4. Strengthen the daily maintenance of vibration motor, remove the dust on the motor surface frequently, and reduce the impact on the vibrating motor due to the poor heat dissipation in order to make it work in a good condition.

5. Please pay attention to the symmetry when adjusting the vibration block, the gravity connection centerline of vibration block on both sides should be parallel to axis.
6. Check whether there is crack on motor appearance, all fastening screws and parts are complete and the fixed situation of the motor are in good condition or not.
7. Check whether the ventilation and bearing lubrication condition of vibration motor is normal or not.
8. Pull out the motor axis and check if rotor can rotate freely and whether there is noise during rotation.
9. Check whether the grounding device is reliable or not. 

Selection Method of Conveyor Roller

The choice of roller type, most suitable for a certain application, will be dealt with in the following section but should also take into account other factors such as:

1.The abrasive and corrosive characteristics of the conveyed materials

2.The environmental working conditions of the plant in which the rollers will be installed. 

Abrasive materials such as clay, granite and ferrous minerals may influence the roller choice towards the heaviest series and the choice of a large tube diameter as this result in only a minor contact of the roller surface with the conveyor belt itself. The conveyor transport of corrosive materials such as salt and chemicals requires the chosen rollers to be protected or manufactured from the appropriate materials that are time resistant to the corrosive substance. The rollers may be in steel, covered with several layers of a particular specification of paint, or covered in rubber or in other anti-corrosive materials. Otherwise the rollers may be entirely manufactured from plastic materials that are resistant to corrosion. Environmental conditions where, in particular, dusty conditions prevail (cement, limestone, ash) rollers with the very best sealing systems that offer the highest possible protection are required.
