Hydrocyclone for Coal Mining Pit and Sands Mining Pit

Hydrocyclone for coal mining pit and Sands mining pit 

1. Description of sand cyclone:

Sand cyclone widely applied in mine chosen technique in various metal mines as the following works:
1). Classification for section I closed circuit grinding
2). Classification for section II closed circuit grinding
3). Regrinding for fine mine classification
4). Mud-removing before selection and after selection
5). Dam and backfill for gangue
 
In closed circuit grinding system, it features high classification efficiency and fine overfall fineness under high mine concentration. 
Classification efficiency is higher for 5-10% than common screw grader.  It benefits for  enhancing grader utilizing coefficient.
  
2. Structure of Hydrocyclone

3. Working principle of sand cyclone: 

A typical hydrocyclone consists of a conically shaped vessel, open at its apex, or underflow, joined to a cylindrical section, which has a tangential feed inlet.The top of the cylindrical section is closed with a plate through which passes an axially mounted overflow pipe.The feed is introduced under the pressure through the tangential entry which imparts swirling motion to the pulp.This generates a vortex in the cyclone. The light granules will be pulled out by a pump through the overflow pipe, while the heavy particles will be discharged with the pulp through the underflow discharge.
 
3. Technical Specification of sand cyclone: 
 

 
4. Features of sand cyclone and Coal cyclone:

1)Simple structure, light and flexible, no moving parts;
2)Low equipment cost, easy disassembly, maintenance, less the cost of infrastructure
3)Large handling capacity, Can handle the small particle size to about 10μm
4)High efficient classification. 
5)Slurry in the cyclone retention volume and time very small, easy to deal with when the machine stops.
6)Long service life, large disposal capability, small land covering, no driving power consumption.
7)High efficient grading & de-sliming equipment of fine -particle material.
 
5. Application Area:
 
1). Gas / Fume filtration for industrial boiler .
2). Metallurgy Furnace fumes filtration
3). Wood working plant 
4). Machine processing plant 
5). Powder processing plant 
6). cement production process

12.FAQ
Q1: Is your compqny a reliable company?
We are a factory, compared with trading company, we have more advantages as below:
1)competitive price
2)customers can test our machines at anytime.
3)repairing the machine in time.
4)on-time delivery
5)10 years manufacture experience
Q2: What about the delivery?
For dredgers in small size we could ship it in containers. But for large one, we will tranport it in bulk. That is why the dredger structure has to be dismantled. After arriving work site, we will send engineers to install and adjust it.
Julong always has various dredgers, aquatic weed harvesters etc. in stock. Spare parts are available too. Thus the delivery time can be shortened. 
Q3:What is the delivery time?
Under normal circumstances, the delivery time shall be within 50 days after receiving the deposit here. But at the moment we have 12inch and 18inch dredger in stock. The delivery time for them will be asured within 30 days.
Q4: What's the payment method?
We can accept T/T, L/C, WESTERN UNION and so on.
