Question 1

How to reduce noise during the briquetting process?

Accepted Answer

one of the reasons is the temperature or the water content in the raw material is out of normal range, and the corresponding solution is drying materials by the dryer to ensure that the materials are kept at proper temperature and humidity.

Another reason is that there are damages with the parts of the briquette machine, such as the screw conveyor is worn seriously. When it happens, the parts of the briquette machine should be replaced immediately.

Question 2

How to prevent the briquette machine from frequent restarting?

Accepted Answer

Repeat restart of the briquette machine is usually caused by the low power supply, which can not drive the briquette machine to work normally.

First, the power supply voltage of the briquette machine is detected by AVO meter, and it'd better detect under the condition that the briquette machine is loaded so that to judge whether there is any power supply problem.
In addition, when the briquette machine works normally, the power voltage would better be no less than the standard voltage. When the standard voltage is at the value of 24VAC, the voltage fluctuation should be no more than 25%.

Question 3

What is the cause of insufficient oil pressure of briquette machine?

Accepted Answer

The reason causing such a problem may be the blockage of oil suction or the deformation of the joint gasket.

Question 4

How to improve the water-resistance of briquette machine?

Accepted Answer

The inclination is designed to lift the screw end of the briquette machine, preventing the back-flow of water.

Question 5

How to perfect the briquetting effect and quality of material?

Accepted Answer

Mineral powder briquette machine, coal powder briquette machine and others may cause the deformation problem of materials, and the reasons are usually the insufficiency of materials fed, the insufficient hydraulic pressure, the damaged roll surface, etc.

The insufficiency of materials fed may cause the deformation of materials. The feeding speed can be adjusted to add the feeding volume.
Insufficient hydraulic pressure may cause incomplete compression of materials. The rotating speed of the engine can be reduced so that to improve the hydraulic pressure of the briquette machine.
The damage of roll pressure may reduce the pressure of materials formation, the damaged surface can be fixed or replaced to improve the briquetting performance.
When all the factors that influence the briquetting performance meet the criteria, the adhesion agent can be added adequately to improve the briquetting ratio. The volume of adhesion agent is usually controlled in the range of 4% to 8%, sometimes in the range of 2% to 3%. By the way, it also can be experimented firstly to set a suitable ratio.

Question 6

Why doesn't the material off-line after briquetting?

Accepted Answer

There are the following reasons caused that materials don't off-line after briquetting:

The water content of materials is improper. Solution: in general, the water content should be controlled in the range of 8% to 13%. If the materials contain more water, it can be drying by dryer if there are a lot of materials, while it can be drying naturally to save cost.
The roller of the briquette machine is designed improper or the ball socket is too small. Solution: when choosing the briquetting machine, it should be better to choose the briquette machine with the ball socket diameter more than 3 cm.
The briquetting machine rotates at a low speed. Solution: the rotating speed of the briquette machine should be set at 10 to 20 per minute.

Question 7

Why is the dislocation of briquette machine's rollers?

Accepted Answer

First, the driven gear should be found, because there is set an adjusting panel. Second, loose all the screws on the adjusting plate, so that to make the panel adjustable. Third, measure the dislocation gap between two sockets, adjust the gap to set the sockets in a proper position.
When there is a dislocation between sockets, except the adjustment of sockets by scientific methods, there still should be paid attention to the shaft. Therefore, the shaft should be checked whether there is any damage.

Question 8

How to prevent the product from deformation after the briquette process?

Accepted Answer

The deformation is caused by much water contained in the raw materials. To solve this problem, the water can be removed by the methods of natural-drying or dryer-drying.

Question 9

Why are the materials blocked in the briquette machine?

Accepted Answer

The materials are mixed with hard particles and big impurities.
The voltage of power supply or the temperature is under the criteria.
The raw materials are much humid.

Question 10

How to reduce the dust during the briquetting process?

Accepted Answer

If there produces much dust during the briquetting process, the cyclone dust collector can be equipped as the corollary equipment. The dust collector has the advantage of cleaning the dust in the machine immediately and improving the working efficiency greatly.
