What Should We Note During the Installation of Large Angle Belt Conveyor

Large angle belt conveyor can be transported with large inclination , it even can be vertical. It adopts sidewall belt as the main part. The advantages are: large conveying amount, small space occupation ,small noise etc. which is widely used for conveying powder, blocked material. Here PK Machinery will introduce the installation notes during installation:
1.Check whether the components of large angle belt conveyor are complete or not
Generally speaking, belt conveyor includes lots of components: head & tail frame, concave & convex segmental arc frame and middle frame, however, the quantity of trough roller frame, rollers and sealing cover is big, you need to check carefully and guarantee the components are transported to the right place.
2.Installation, positioning and welding of head and tail frame, concave and convex segmental arc frame
First of all, please find the center line of the belt conveyor by using a steel wire. When installation, please make the head & tail frame, concave & convex segmental arc frame subject to the center line.

Three Horizontal Sections of Large Angle Belt Conveyor

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.

Why will Belt Conveyor Motorized Pulley Get Rusty

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.

Please Focus on Belt Speed 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.
