As we all know, sometimes conveyor rubber belt deviation occurs during operation, in this way, we should find out the reasons that lead to belt deviation, otherwise, it will seriously affect the normal operation of belt conveyor.
Rotary vibrating screen uses a heavy weight (unbalanced heavy weight) installed at the upper and lower ends of the motor shaft, which converts the motor rotating motion into a horizontal, vertical and inclined three-dimensional motion, and then conveys this motion to the screen surface. Different phase angle reaches different screening effects. Client can adjust the appropriate phase angle according to the need
Have you ever noticed the bouncing balls jumping up and down on the sieve mesh when the vibrating screen works? What's special role of bouncing ball? Today we will take a brief look.
Gyratory Screener is a new type of screening equipment developed mainly for large urea, meanwhile, it is widely used in chemical, food processing, refractory materials, building materials and other industries of screening operations, the advantages are as follows:

1. Chain scraper conveyor can transport the material bulk density: 0.1-2.5t/ cubic meters; 2. Material temperature: material temperature for general model is less than 100 degrees Celsius, high temperature resistant type buried scraper conveyor conveying material temperature can reach up to 650-800 degrees Celsius;

1. Screw conveyor is widely used in chemical industry, building materials, food and other department, and it is also applicable for conveying powdery, granular and small lump material. However, material which is perishable, viscous and easy to agglomerate are not suitable.
1. Cylindrical radial circular runout It is necessary to make strict specifications on roller radial circular runout so as to guarantee the belt conveyor running smoothly, otherwise conveyor belt vibration will occur, increasing conveyor belt running resistance and consume more power due to its higher value.

1.Gyratory screen body obliquity Such as torsional vibration, the main reason with emphasis on block improper installation, shaft bending or bearing damage. For these trouble,we can make corresponding adjustments.
As a fine sieving machine, rotary vibrating screen is well received by the majority of users. However, in the operation process of rotary vibration sieve, it can not operate normally due to various reasons, which brings trouble for the users, Here PK Machinery will list some tips to solve this failure:
Following article will introduce ultrasonic vibrating screen troubleshooting: 1. Ultrasonic power supply does not work: check the connection cable is connected or not, ultrasonic power switch is open or not;

Scraper Chain is the key working part for scraper conveyor, most of conveyor failures are related to the running status of scraper and chain, the manifestation is scraper chain deformation or break.
Belt conveyor pulley plays an key role in belt conveyor, it can transmit traction for belt conveyor,changing direction of the conveyor belt;

Circular Vibrating Screen is a kind of new and highly effective vibrating screen which can be designed with multiple layers. It is composed of screen box, screen mesh cloth, suspension (or support) device, bottom frame and motor.
Better scraper chain conveyor installation is the deterministic factor that whether the machine can be operated normal. Here PK Machinery introduce the method from the following steps:

Generally speaking, it’s really necessary to install safety protection device on bucket elevator so as to ensure safe and normal operation. Now, what is the significant inspection standard for equipment quality is that to minimize or completely eliminate all kinds of risks. According to structure of bucket elevator, there are many kinds of safety protection device.

1. The operation of belt bucket elevator (the transport material characteristics, working conditions, throughput, etc.), shall comply with the instructions specified; super large and super viscous material can not be available.
As we all know, screw conveyor is a conveying equipment which transport material under the help of screw blade rotation. If the conveyor length is too long, the screw shaft will collapse, so we need to install the intermediate bearings to avoid the excessive abrasion due to the shaft collapse, besides, that’s why the hanger bearing is the most easily wear part.
There are 4 kinds application fields for silicon carbide, that are functional ceramics, high grade refractory material, abrasive material and metallurgical material. Different particle size silicon carbide will be used in different kinds of application field, thus it needs different model of vibrating screen.
If there are any shut-down during the operation of linear vibrating screen, inspect the power supply first, and check the vibration source - vibration exciter.

Daily, weekly, monthly inspection of rubber belt conveyor is shown as follows: Daily inspection Mechanical items : guardrail, crossing bridge, belt conveyor roller, drum pulley, bend pulley and belt.
1. Before starting up the vibrating sieve, please make sure there is no items affect the movement of screen box in the working zone, then feed the material into the screen.
Belt deviation occurs in rubber belt conveyor sometimes. In this case, we should find reasons which leads to belt deviation first. Since there are many reasons that cause this situation, if reasons can not be found, it will seriously affect the normal operation of belt conveyor. Speaking of which, the adjustment of tension degree is the one.
Belt conveyor pull cord switch is commonly known as ‘emergency stop switch’. When the belt conveyor need downtime, pull cord switch action will stop the conveyor. Pull cord switch can be divided into manual reset and automatic reset.
Common failures of belt type bucket elevator include material block, material return too much, belt deviation, belt slip and other problems. Another situation is that the capacity can not reach the requirement. However, the main problem is material block problem caused by material return too much as well as belt deviation problem.
