Automatic Coal Sampler

Product Description

Leveraging on our rich industry expertise, we have been able to manufacture, export and supply Automatic Coal Sampler. These samplers are manufactured in accordance with stated requirements of our valued patrons and in compliance with set norms and regulations of this domain. We have been offering these samplers in both manual as well as PLC operations with total moisture adaptability. Our offered samplers are used in various industry applications with adjustable and non-adjustable dividing ratios. Some striking features of our offered Automatic Coal Sampler are as follows:

APPLICATION:Automatic Coal Sampler

WHERE THEY ARE USED: Rotary Samplers are used mainly in the coal industry to acquire

samples of coal from a continuously moving conveyor belt. They are often located at Conveyor Gallery ,rail or

barge loading facilities. Samples are used to check or guarantee product analysis. Air is usually not available

at these locations, so electrically actuated units are required.

HOW THEY WORK: The sampler is a large round scoop which rotates one revolution per cycle

perpendicular to the coal flow. It cuts a swath through the coal and throws a sample into a chute. The

coal sample is taken via the chute to the analysis equipment. The high inertia scoop must be accelerated

to full speed within 90 degrees rotation to insure it will have enough power to cut through the coal as it

travels along the conveyor belt. The scoop must be stopped within approximately 30 degrees rotation

after it has passed through the coal.

The cycle rate can vary from one every few minutes to three cycles per minute. The sample scoop

rotation speed is determined by the conveyor belt speed. On high-speed narrow belts, the scoop

rotation speed gets very high, requiring quick actuation, and short accel/decel times.

PROBLEMS SOLVED:

1. Compressed air was not available; therefore an electric actuation system was developed

and implemented with great success.

2. The high-speed actuation system brought the sampler scoop up to speed within the required 90

3. This is a continuous process with limited time for loading. The long-term reliability of such system

IMPORTANT FEATURES:

Totally enclosed, sealed design eliminates problems associated

with dust, dirt, water, or other contaminants.

Electric actuation system provides quick engagements and

simple regulation of torque and accel/decel rates.
