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.

3.Check belt running and adjust the belt if it runs off tracking
After installation of belt, trough roller, self-aligning roller and vertical roller, connect the power supply , run the belt and adjust the belt offset distance .
4.Installation of large dip Angle belt conveyor accessories and bolts
After adjusting the belt, you can start to install the sealing cover, head cover and fastening bolts.

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.

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 smoothconveyor belt transition.

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.

 

How to Prolong Working Life of Belt Conveyor

    Belt conveyor widely used in mining, metallurgy, coal, fertilizer, chemical, cement and other industries. The usage of belt conveyor is to convey bulk materials or pieces materials to another location according to different transferring requirements. The conveying systems can comprised only one belt conveyor or several conveyors or combined with other conveying equipment. The belt conveyor can be installed horizontally or incline to satisfy the clients requirements.  

 The reliable operation of belt conveyor is vital in industries. The risk of failures in operations needed to be eliminated. The technical team or mechanical workers should do inspection regularly and pay attention to the case or parts. The conveyor belt life span can be extended up to 4 times if transfer points are controlled correctly. The conventional chute systems or transfer points generally drop the material from point A to point B.  The height of the drop normally is not taken into account however this is the most critical factors that affect belt conveyor lifespan. The dropping products with lump sizes up to 500 mm directly onto an outgoing conveyor belt will create a massive impacts and resulting in belt damage over a short period. 
    Besides, the foreign objects which move through the systems also affect the life span of belt conveyor. When a new underground mining operations are being established, there are some foreign objects such as concrete, iron, pillars and steel ropes may fallen on the belt conveyor. This normally will cause blockages or stoppages. Controlling the flow of materials onto conveyor belt is to reduce impact has become a topic for discussion and numerous solutions being proposed. There are a lot information are needed to design on a transfer point which satisfy the proposed concept. The information includes product type and consistency, conveyor trajectory angles, transfer height and distance.   
    Just obtaining this information is not sufficient, it is necessary to do an on-site assessment to verify the data. This enable engineers to tackler other issues which could be causing impact damage on the belt conveyor. In addition, uneven conveyor belt loading, flooding of the belt and blockages could cause damage too. A good design of belt conveyor can prolong the life span and increase the efficiency of the operation.

Necessity of Belt Cleaner

Belt cleaner is a scraper for the belt conveyor. Belt conveyor is used to transport raw materials of ironworks industry, mining, fertilizers, power stations and etc. Normally after conveying raw materials, fine powders and mud often stick on the surface of the belt conveyor. This can cause numerous problems of adhesion to peripheral equipment, meander of belts, falling products and deterioration of work environment. All this problems can be fixed by a belt cleaner. Belt cleaner can prolong the life of belt conveyor, improve working environment, effective utilization of resources and cost reduction. 

A belt cleaner consists of a pre-cleaner and a T-cleaner (Secondary Cleaners). The pre-cleaner or known as primary cleaners has excellent abrasion resistance and uses polyurethane blades which are friendly to conveyor belt. It always keeps optimum surface pressure by spring-tensioned structures and there is no troublesome tension adjustment. It can be replaced safely in short time by aluminium cassette system. The T- cleaner uses super hard chip for blade materials which is excellent of abrasion resistance, long life span and low running cost. It always keeps optimum surface pressure by spring tensioned structure just like pre-cleaner. The tensioner can be set on inside and outside of shoot. It is easy to select space for setting. It also can be replaces safely in short time by aluminium cassette system.

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.
