Conveyor coal analyzer AGP-K-4

Conveyor analyzer AGP-K-4 is designed for continuous in-stream characterization of coal and coke to improve beneficiation, sorting, blending, inlet and outlet control at shipment processes. The ash analyzer is a set for on-line measurement of coal ash content. The device is installed on the conveyor for fast and accurate measurement of coal ash content.

The analyzer determines:
– Ash content
– Moisture
– Heat of combustion
– Mass concentrations of C, O, P, Si, Mg, Fe, Al, Ca, Ti, Na, K, S
– Mass concentrations of SiO2, Al2O3, Fe2O3, CaO, K2O, TiO2, MgO, Na2O

The analyzer is placed between the idle and working belt of the conveyor and provides constant control of coal and coke quality characteristics, which makes it possible to promptly correct the course of technological processes.

Russian equipment. We provide full service support on the basis of remote access.

The analyzer provides data on elemental composition of coal on the conveyor every 40-60 sec.

Material flow is analyzed for the whole depth of coal layer up to 300 mm

Is a measuring instrument. Registration number in the Register of Measuring Instruments No. 92304-24.

Real time, without sampling

Where to install the AGP-K-4 analyzer?

The analyzer is built directly into the conveyor line for continuous quality control of coal and coke in real time. Does not require calibration by coal or coke brand.

Main installation points:

After extraction, before enrichment

For what:

Sorting of raw coal by impurities and ash content directly from the face or quarry.

Profit:

Optimal distribution of coal along technological streams and effective planning of enrichment.

At the entrance of the processing plant

For what:

Constant control of characteristics of incoming raw coal.

Profit:

Automatic adjustment of enrichment parameters for maximum yield of high-quality concentrate.

On the finished product shipping conveyor

For what:

Final quality control of concentrate before sending to the consumer.

Profit:

Guaranteed compliance of concentrate with declared parameters (ash content, calorific value, moisture).

How it works:

Real-time data is transmitted to the production management system

Works with coal of any size class up to 300 mm

Measures key parameters without sampling every 40-60 seconds

Works with any coal brand at any ash and moisture ranges. No separate sub-calibration for different raw materials is required.

The analyzer is installed under the conveyor — the entire coal flow passes through it

What it gives:

Continuous control of ash content, moisture, calorific value without need for additional determination of coal brand

Optimization of processes of enrichment and blending of coals

Stable quality of finished products

Cost reduction for laboratory analysis and sampling

Measurement errors

Element	Coarseness, mm	σ_r , %	σ_r relative, %
Mass concentration of carbon	0 - 2020 - 100	0,160,12	0,290,23
Ash content	0 - 100	0,13	0,35
Humidity, W^r , %	0 - 20	0,64	4,57
Specific (lower) heat of combustion, Q_i , kcal/kg	0 - 20	59,4	1,14

σ_r is standard deviation, absolute σ_r relative = σ_r /А, where А is the average value of the variable in the content range

Operator interface

The data appears every 40-60 sec, the user can also set the required time of 5, 10, 15, 30 min, shift, day to output the averaged data.

The operator interface shows trends in elemental concentrations, ash content, moisture content and specific heat of combustion.

The interface can be adapted to customer requirements.
