How to control the conveying speed of the conveyor

Conveyor speed control
To prevent speed variation caused by belt conveyors, bucket elevators, screw conveyors and feeders and other damage, you need to set the safety switch. Due to overloading, belt

slippage or fracture occurring at a rate change, the switch should perform two functions, namely cutting system startup sound

Light alarm.
Speed ​​switch shaft through flexible coupling shaft connected with the conveyor for measuring conveyor rpm. At any speed setpoint changes increase or decrease in both the

switching action. As a typical system, when the drag chain conveyor speed changes will stop functioning, warning lights

Or start flashing alarm. Speed ​​switch can simultaneously perform multiple functions.
Speed ​​switch can use the following three modes.
Speed ​​reduction detection: detection speed should be set below the normal operating speed, when the operating speed drops below the set value, the output relay is de-energized.
Speed ​​detection: the detected speed should be set above the normal operating speed, when the operating speed exceeds the set value, the output relay is de-energized.
Zero speed detection: When the operating speed is close to zero (half turn per minute), the output relay de-energized.

Emergency stop
For most of the conveyor system, have a stop button for emergency stop in case of emergency. For longer conveyors, which normally takes along its entire length rope emergency

stop switch, start button will only be installed in the main control board.

System Control
Delivery system can be operated with a manual control (in the test or automatic control malfunctions during use) or by automatic control, automatic control available electrical,

electronic or pneumatic.
Control system design must be able to meet the operational requirements. Open to stop the program, interlock, time and records must meet the technological changes in the change.

Stop when troubleshooting system can operate independently of local disconnect. Most bulk solid materials conveying systems are used to make the system delay relay

In order to stop or start. System startup are generally in the control room.
Conveyor system must be set up between the devices in the cell electrical interlock. Set in the power control system electrical interlock, can any one conveyor system

malfunction or stop, it can automatically stop all feeding conveyor, also can ensure that before the start of either a conveyor, which

The pick conveyors are in operation.
When the material reaches a predetermined height of material level, the system will automatically cut off; stop the star feeder; were stopped No.1, No.2, No.3 belt, over a

certain time interval after stopping to ask valve dust device fan.
Closed the entire running motor by detecting switch control, electrical interlock, so that all devices in any one accident shut down will stop to the raw material silos. Silo

material material level reaches the upper or lower limit and an alarm.

How to buy loaders

Loader is loading the soil, gravel, coal-based materials, such as comprehensive a large, medium and small multi-purpose high-efficiency construction machinery for mines, ports,

infrastructure, road construction and other operations, widely used factories, railway stations, docks, garages, warehouses and other working conditions. For loaders users, in

order to obtain higher yields, reduce investment risk, in the purchase of a product when you can not only consider the price factor, but should be weighed against many, Metal detector for food

according to different uses and the spirit of "good enough, easy to use "and" get the most comprehensive income "principle to buy.
1 according to the amount of work to determine the corresponding rated load loader
How much load loader loader users to buy in order to achieve best value for money, they have the spirit of the principles of practical enough, according to the amount of work to

determine. That is not too large nor too small, too big wasteful, too small, not enough to use.
For road construction jobs and large coal mines, because of the heavy workload, the work cycle is longer, more spacious working environment, with the support of transport

machinery are more than 10 tons deadweight, then you should select 5 tons or 6 tons load weight loaders, which can improve operational efficiency, reduce construction costs. For

a relatively small amount of work situations, such as earth, sand and other general selectable 3 tons or 4 tons deadweight product, especially for a small amount of work, such

as some small individual gravel pits, supporting the vehicles are generally for small tractors , 1.5 tons or less general choice of products in order to avoid excess capacity   automatic checkweigher

loader operation, so as to achieve economic and practical purposes. This loader higher degree of component commonality, so it is also more convenient maintenance.
(2) determine the appropriate working condition according to driving speed loaders
For denser ore, solid original soil or loose material such as low density soil, coke, etc., because of its different operating conditions, select the loader also has a greater

difference.
For those solid original soil, ore and other large density of the material, due to traction (Insertion Force) require a higher operating speed should be selected lower breakout

force and traction are larger products to ensure normal use. Because of loose material on the loader traction (insertion force) do not ask, you can choose products with higher

driving problem to get higher operating efficiency. As a result of the different media, many companies have launched a working medium for a particular purpose-built products.

Rod-type feeder and feeder introduction of commissioning and maintenance

Rod-type feeder is a new feeder, in the production process, can the massive, granular materials from storage silos in uniform, regular, continuous given to the affected device

in the gravel production line crushing machinery for continuous uniform feeding, and coarse screening material, widely

Used in metallurgy, mining, electricity, building materials, chemicals, machinery and other industries crushing and screening operations.
GZT Series rod vibration feeder has five specifications for crusher evenly before feeding bulk materials. Particularly suitable for ferrous or nonferrous ores, building stone

crushing feed before use.  industrial belt conveyor
1 working principle and structural characteristics
GZT Series Vibrating Feeder new vibration motor, the series vibrating feeder for coarse crusher evenly before feeding, and because of the role of bar screen surface, but also to

get rid of dirt and other fine materials, reaches a pre-screening the function can be improved crushing capacity.

resistance, abrasion resistance, easy maintenance.
2.GZT Series Feeder rod style of the structure analysis
GZT Series rod vibration feeder by a rotatable disc, guide sleeve and the blade materials and other components. The material within the hopper through the guide sleeve material

deposited on the disc with wear-resistant liner disc rotation, the material scraped by the scraper feed. Regulating blade location or level of material guide sleeve can be

changed  material handling conveyor

Variable feeding amount. Disc diameter generally 3 meters below the speed does not exceed 10 rev / min. Disc feeder smooth and reliable operation, adjust the feeding amount is

more convenient, less energy consumption, but the structure is more cumbersome for smaller sticky powder granular materials.
Some of the feeder from the housing and impeller components. This feeder relatively simple structure, small size, light weight, feeding when closed, good for small size and

powdered materials. Casing, the bottom of the inlet and outlet ports, respectively, and silos, by feeding equipment connections. Wheel about a horizontal axis

Material falling into the impeller rotates between the cells in each chamber, with the impeller rotation by a half weeks after discharge into the feeding equipment. Equalizing

pipe can enter the feed zone to go before the high-pressure chamber vent grid, in order to avoid the feeding area can not feed. Impeller diameter of 500 mm below normal, the

speed does not exceed 45 rev / min.


How to debug and maintain vibrating feeder
Since the principle of the feeder is relatively simple, so long as the principle of control over their work and structure, under the guidance of the theory, combined with

practical maintenance experience will be able to do a good job of electromagnetic vibrating feeder maintenance and debugging. Electromagnetic vibrating feeder is a more complete

dual particle orientation bomb forced vibration

Of the system. The entire system operates at low critical resonance, its simple structure, stable, power loss is small, widely used in the cement industry, but for now the use

of some units of view, there are more common improper maintenance, work status is unstable, the use of After a period of time

Delivery of materials decreased significantly and other issues. Plus not correct commissioning after maintenance, resulting in poor stability of the equipment, which seriously

affected the normal production.
Electromagnetic vibrating feeder adjustment, debugging mainly electromagnet core gap adjustment, dual particle spring plate connected group of adjustment, debugging.
Air gap between the electromagnet and the armature core tuning
Electromagnetic vibrating feeder air gap between the core and the armature directly affects the size of the normal operation of the feeder, such as improper adjustment of the

light so that the current increase, the amplitude decreases and can not operate normally, severe collisions will produce core The resulting damage to the core and the coil. So

frequent on the gas

Check and adjust gap is an important condition to ensure operation.
Connect dual particle group to adjust the spring plate
Amplitude of the trough there are two factors: First, the feeder electromagnetic exciting force size, frequency, the second is the feeder's own natural frequency. According to

mechanical vibration resonance principle known only when the feeder with the natural frequency of the excitation frequency close to the electromagnet resonance when the

amplitude of the trough

Max.
Dual particle method for adjusting the spring plate group: adjustment of the machine to the air gap adjustment is completed, you can start to adjust the stiffness of the spring

plate group. Loosen overhaul screw, connected to control power, a gradual increase in operating current at the same time, observed in the amplitude of the electromagnetic

vibrating feeder signs

The indicated value. When the current reaches its maximum, and reach maximum amplitude can be set on the top of the spring plate screws slightly loose, then as the amplitude

increases, the current decline, then the spring stiffness is too large, should reduce reed the number of blocks to reduce the stiffness. Instead it should increase the number of

spring

To enhance the overall stiffness. Short as long as the adjustment can be repeated carefully tuned to achieve the best value is to determine the role of the amplitude of

vibration signs point vibration amplitude, measured two lines dividing point is the value of the amplitude values.
