2. BASIC PRINCIPLE
1.
1. Mobile modular coal preparation system is a small-scale DMC coal washing plant with compact structure and arrangement.
2. DMC system also has screening machinery, dense medium cyclone, magnetic concentrate recovery system, all kinds of hopper and other
auxilliary equipment.
3. Installation of DMC system is very quick and simple, no complex requirement, only needs a plain and solid position. It usually takes about
3-5 months to complete whole plant construction and go into production.
4. It doesn't have high requirement about feeding raw coal property, the washing performance can be capable with traditional coal washing
plant when treating hard-to-wash coal.
5. Feeding size: 50mm-1.5mm, capacity: 50-250TPH.
6. Mobile modular coal preparation plant has advantages like low electricity consumption, low water consumption and low medium
consumption. It can use industrial water and could control the ultilization of magnetite more precisely.
7. Equipped with HOT Mining coal preparation plant intelligent expert system, the production management could be more effective and
convenient, and save labour cost meanwhile.
8. HOT Mining can customize unique mobile modular coal preparation plant according to clients' different requirement, and provides
production-operation contracting service after construction.

3. MODULAR CPP - PROCESS FLOWSHEET (DMC MODULAR)

4. MODULAR CPP - WHOLE FLOWSHEET

5. MODULAR CPP - WORKFLOW
1. Feeding - Raw coal material with up to 250TPH capacity goes into pre-wet-screen for desliming.
2. DMC separation - Material goes into DMC separation equipment after desliming, in this stage coal and gangue are separated from each other
under the action of medium suspension.
3. De-medium - Coal concentrate and gangue go into de-medium screen respectively.
4. Medium recovery - By using magnetite recovery system in magnetic separator, the concentrate could be recovered and ultilized again.
5. Water consumption - Wet desliming by using clean water or circulating water. Add clean water into de-medium screen to wash magnetite
powder adhered to coal concentrate.
6. Power consumption - Normal power consumption is < 50KW according to mobile modular coal preparation plant's scale.
7. Automation control - With HOT Mining industrial automation system, the module could be controlled manually or remotely and automatically.

6. If product surface moisture needs to be kept at 5%-10%, an horizontal or vertical centrifuge
could be configured to decrease product moisture furtherly.
One set of high-efficiency and quick-open filter
press could be configured to ensure product
quality and protect environment, as the case may
be.
MODULAR CPP - ALTERNATIVE EQUIPMENT

7. We can add flotation module for coking coal in order to maximize coal concentrate recovery rate. Either agitation impeller flotation
machine or jet flotation machine or flotation column could be chosen according to specific condition of coal features.

DESIGN METHOD - 3D DESIGN

10. DESIGN PROGRESS - 3D MODELING

11. ADVANTAGES OF 3D DESIGN
1. Strengthen engineers' understanding about whole system, which is good for design optimization.
2. Efficient and accurate design can effectively shorten later installation time.
3. A 3D-designed coal preparation plant can be delivered to client, which is good for employee training.
4. Intelligent coal preparation plant expert system can make production management more convenient.
5. Finally achieving better ecnomic benefit and ensure ROI.

12. CHARACTERISTICS OF MOBILE MODULAR CPP
1. Brand new process - Greatly reduce capital construction investment and increase flexibility of washing and preparation process.
2. Low investment - One-time investment of R.O.M per ton is far less than conventional coal washing plant with same equipment configuration.
3. High efficiency - Washing and preparation efficiency can reach up to 97%.
4. Great flexibility - The modules can be added or eliminated according to client's requirement, thus washing process can be changed flexibly.
5. Stable product quality - Fluctuation range of separation S.G. is <0.005.
6. Advanced process index - Power consumption <4.7 Kw/h/ton of feeding R.O.M, medium consumption<1kg/ton of feeding R.O.M (thermal coal),
water consumption<80kg/ton of feeding R.O.M.
7. Short construction period - It only takes 3-5 months for completion and goes into operation.
8. Convenient production management - With coal preparation plant intelligent expert control system, the operation management can be more
efficient and convenient.
9. Low instalion cost - With modular design, only small workload for on-site preparation and installation.
10. Easy to move - It only takes about 2-3 weeks for plant relocation and to be installed at other places.

Process Technology
1. Raw coal (80-1.0mm) use big diameter cyclone to wash
and separate, add re-washing system if needed.
2. Coarse coal slime (1.0-0.1mm) use HTBS
3. Fine coal slime (0.1-0mm) use filter press to recover,
closed water circuit.
4. Flotation module could be added according to different
kind of coal
1. Jig or other complicated process (most)
2. All DMC process (few)
