Three Horizontal Sections of Large Angle Belt Conveyor

Three Horizontal Sections of Large Angle Belt Conveyor

Three horizontal sections of large angle belt conveyor are upper horizontal section,lower horizontal section,inclined section. Here we will introduce you detailedly.

Large angle belt conveyor is suitable for the unit mass of 500 ~ 2500 kg/m3 and the material large size of about 100 ~ 250 mm, the features of large angle belt conveyor are: simple structure, convenient maintenance, space saving and investment saving. Here PK Machinery will explain and introduce three kinds of horizontal section:

1. Upper horizontal section

In order to adapt to the requirement of different discharge height, the head frame is divided into low type frame (head frame height = 1000 mm), middle type head frame (head frame height = 1100 ~ 1100 mm) and high type head frame (head frame height = 1600 ~ 1600 mm).

Correspondingly, low type convex segmental arc frame and low type middle frame support (matched head height = 1000 mm), middle type convex segment frame and middle type frame support (matched head frame height = 1100 ~ 1500 mm), high type convex segment frame and high type middle frame support (matched head frame height = 1600 ~ 1600 mm) will match with upper horizontal section respectively.

2. Lower horizontal section

The lower horizontal section adopts low type middle frame support.

3. Inclined section

The inclined section of large angle belt conveyor adopts low type middle frame support. When the conveyor inclined angle β ≧ 45 °, we suggest adopting Ⅱseries low type middle support.

The connection of upper horizontal section and inclined adopts the convex arc segments frame , and the lower horizontal section and inclined section adopt concave segmental arc frame to connect so as to realize the smooth conveyor belt transition.

 

Please Focus on Belt Speed Selection and Principle of Belt Conveyor

Please Focus on Belt Speed Selection and Principle of Belt Conveyor

Do you know how to select suitable #belt speed? This article will analysis its selection and principle of #belt  #conveyor  .

As we all know, the most decisive factor of belt conveyor throughput is the belt speed, here we would like to introduce the selection method of belt conveyor belt speed: 

(1) If the conveying capacity of belt conveyor is large, belt width is wide, please select a high belt speed.

(2) If the material is easy to move with big granularity and strong grinding property, please select a low belt speed.

(3) If material conveying interval is long, please choose a high belt speed; If material conveying interval is short and the conveyor angle is big, please select a low belt speed.

(4) If there is large amount of dust during conveying, the belt speed would be 0.8 m/s ~ 1 m/s.

(5) If belt conveyor works with a discharging tripper, the belt speed should not be higher than 2.5 m/s.

(6) If belt conveyor conveys finished product items, the belt speed should be less than 1.25 m/s.

Belt speed selection principle of belt conveyor : the belt speed of belt conveyor is related to belt width, throughput, material size, material properties and conveyor angle. When belt conveyor transports upward and dip angle is large, the tape speed should be low; When belt conveyor transports downward, the belt speed should be much lower. Belt speed selection also should match the cooperated material discharging equipment type, when adopts plough type discharging machine, the belt speed should not exceed 3.15 m/s.

 

Maintenance Method of Portable Belt Conveyor in winter

Maintenance Method of Portable Belt Conveyor in winter

In winter, portable belt conveyor will work in the outdoor and suffer from rain and snow, in this way, what shall we do to maintain portable belt conveyor to achieve the purpose of long-term steady operation?

1. Maintenance of motor

Concerning the operation process of portable belt conveyor in winter, motor will be the main part we should protect. Although motor damage rate is very low, if motor overloads it will still damage. As we all know, temperature is pretty low in winter, motor lubrication condition is not very good. Therefore, the motor of portable belt conveyor should be checked and maintained regularly .

2. Overall antirust processing for the whole machine

Though before leaving factory, portable belt conveyor was already painted again and again, after being checking, we found out that most of the conveyors are still rusty. This is not the problem of painting, but is the maintenance service of equipment, especially during winter, there is lots of rain and snow. In many cases, these portable belt conveyor are not properly covered in raining and snowing environment. So in the long run, even using the best painting and steel ,the service life of portable belt conveyor will still reduce.

In conclusion, the suggestion is to make the conveyor covered and keep the conveyor away from rain and snow to extend the service life.

3. Maintenance and replacement of spare parts

Conveyor roller is the most used spare parts of portable belt conveyor, so we need to check the wear condition and bearing using condition of roller frequently. Concerning the damaged roller, you should replace timely.

For conveyor belt, please clear up the belt surface and the accumulated impurities timely in order to avoid long time abrasion.

Inclination Corrugated Sidewall Conveyor Belts

Inclination Corrugated Sidewall Conveyor Belts 

As one of conveyor belts to convey bulk materials,corrugated sidewall conveyor belts provide high-quality long-term high-incline conveyance solutions. Large inclination corrugated sidewallbelt conveyors applies to large scale open-pit mines, power plants, cement plants and ports, with the characteristics of large conveying capacity, low energy consumption and convenient maintenance, it becomes a powerful machine. However, during the process of operation, there will be belt failure due to improper use which can lead to skirt and belt tear or fall off, beltsreplacing will increase the production cost, in order to reduce the production cost, it is necessary to study and explore the large inclination corrugated sidewall belt conveyors repairing process points.

                  

Non-load running for 2 hours after installation to check whether there is belt cracking or falling off or not, if any problems please handle timely; Initially, please feed the material as per 50% of design capacity, after running for a period of time and confirming the operation is correct, you can feed material as per design capacity ; If material accumulation is found during operation, please stop running to avoid skirt or belt falling off.

Large inclination corrugated sidewall conveyor belts crack or fall off, you need to pay attention to the following points when repairing: 

1. Clean up the site environmental, and keep the skirt and belt clean.

2. Roughening and cleaning up the belt and skirt connection parts evenly by polishing machine, uneven layer or surface is not allowed to appear.
