How to improve the efficiency of rotary dryer

 投稿者:amily  投稿日:2012年 3月 9日(金)18時09分23秒

There is no denying that we would meet a lot of problems during the operation of dryer。 And we have explained you some basic knowledge of dryer in the news we published before。 How to improve the operation efficiency of dryer is their primary concern。

The rotary dryer is a type of industrial dryer employed to reduce or minimize the liquid moisture content of the material it is handling by bringing it into direct contact with a heated gas。

Because of long-term operation of rotary dryer, the cylinder would move when the tire and wheel attired along the rotation。 It is easy to damage the furnace and device。 For this reason, some experts summarized a set of methods to deal with the movement without effect to the normal operation。

Here we would like to share you some effective methods for our users of improving the operation efficiency。

When the cylinder is down, we should adjust the back wheel of cylinder wheel to the inside in parallel。 We should raise the rear cylinder appropriately。 When the cylinder is up, we should adjust the front wheel of cylinder wheel to the inside in parallel。 It is important to increase the touching area between roller and belt when the cylinder is down。

When the cylinder of rotary dryer moved, the belt of cylinder of dryer would walk aslant。 This phenomenon caused by the abrasion of belt and roller。 Therefore, according to the rotation direction of the cylinder, we should adjust the wheel angle appropriately, and then you can recover the normal operation of the cylinder displacement。

The new type of rotary dryer made from Henan Hongxing Machinery Co。, Ltd improved these shortcomings; this dryer has the superiority of sample structure, large production capacity, stable database, long service life, widely application, easy operation, low consumption and so on

usage of the rotary dryer

 投稿者:amily  投稿日:2012年 3月 9日(金)18時08分8秒

The rotary dryer is a type of industrial dryer employed to reduce or minimize the liquid moisture content of the material it is handling by bringing it into direct contact with a heated gas. The dryer is made up of a large, rotating cylindrical tube, usually supported by concrete columns or steel beams. The dryer slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the dryer under gravity. Material to be dried enters the dryer, and as the dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the dryer. When the material gets high enough to roll back off the fins, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls. This gas stream can either be moving toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow). The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the dryer is called a direct heated dryer. Alternatively, the gas stream may consist of air or another (sometimes inert) gas that is preheated. When the gas stream is preheated by some means where burner combustion gases do not enter the dryer, the dryer known as an indirect-heated type. Often, indirect heated dryers are used when product contamination is a concern. In some cases, a combination of direct-indirect heated rotary dryers are also available to improve the overall efficiency.

Rotary dryer is suitable to dry metallic and nonmetallic mineral, clay in cementindustrial and coal slime in coal mine,etc. Rotary dryer can be widely used to dry various materials, and it is simple to be operated.

operation of the cone crusher

 投稿者:amily  投稿日:2012年 3月 9日(金)18時06分49秒

A cone crusher is similar in operation to a gyratory crusher, with less steepness in the crushing chamber and more of a parallel zone between crushing zones. A cone crusher breaks rock by squeezing the rock between an eccentrically gyrating spindle, which is covered by a wear resistant mantle, and the enclosing concave hopper, covered by a manganese concave or a bowl liner. As rock enters the top of the cone crusher, it becomes wedged and squeezed between the mantle and the bowl liner or concave. Large pieces of ore are broken once, and then fall to a lower position (because they are now smaller) where they are broken again. This process continues until the pieces are small enough to fall through the narrow opening at the bottom of the crusher.

A cone crusher is suitable for crushing a variety of mid-hard and above mid-hard ores and rocks. It has the advantage of reliable construction, high productivity, easy adjustment and lower operational costs. The spring release system of a cone crusher acts an overload protection that allows tramp to pass through the crushing chamber without damage to the crusher.

In operation, the raw material (of various sizes) is usually delivered to the primary crusher's hopper by dump trucks, excavators or wheeled front-end loaders. A feeder device such as an apron feeder, conveyor or vibrating grid controls the rate at which this material enters the crusher, and often contains a preliminary screening device which allows smaller material to bypass the crusher itself, thus improving efficiency. Primary crushing reduces the large pieces to a size which can be handled by the downstream machinery.

Some crushers are mobile and can crush rocks (as large as 60 inches). Primarily used in-pit at the mine face these units are able to move with the large infeed machines (mainly shovels)to increase the tonnage produced. In a mobile road operation, these crushed rocks are directly combined with concrete and asphalt which are then deposited on to a road surface. This removes the need for hauling over-sized material to a stationary crusher and then back to the road surface.

magnetic characteristics of weak magnetic minerals

 投稿者:amily  投稿日:2012年 3月 9日(金)18時02分40秒

magnetic characteristics of weak magnetic minerals: Magnetite can be used as a classic representative of strong magnetic minerals, it belongs to ferrous magnetic material; it have more complex magnetism due to its internal magnetic structure (namely Spontaneous magnetization over small area), the magnetic characteristics can be summed up in the following:

① Magnetic strength and magnetized coefficient is very big, with the phenomenon of magnetic saturation, and can be saturated in the lower external magnetic field intensity.

② There are curvilinear relationship between Magnetic strength, magnetized coefficient and the external magnetic field intensity, and magnetized coefficient is not a constant. Strength of minerals is in relevant with its properties, but also to the historical change of external magnetic field.

③ There are hysteresis of minerals, it still retain some residual magnetism when it deviate from magnetized materials; To remove residual magnetism, a reverse magnetic field should be added to completely remove the magnetic field intensity H, which is called coercive force

④ The magnetism change with temperature, there will exist the phenomenon of paramagnetism when the temperature is higher than the critical temperature-Curie and its internal magnetic structure is small.

⑤ The magnetism changes with the strength of magnetic field in the outside, but also with shape and size of its own particle and degree of oxidation.

each crusher has its own life

 投稿者:amily  投稿日:2012年 3月 9日(金)17時58分34秒

Each crusher has its own life, when the principle axis is used for too long time, it will be out of shape because of the attrition, and the noise will be caused. So, changing the principle axis of the crusher is very necessary. Besides, before the starting, carefully checking the bearing whether it lubricates very well, carefully examining all fasteners whether completely tightened.

Check carefully transmission belt is good or not. If the damaged phenomenon is found, it should be changed in time.

The crusher is allowed only in no load of starting, with the bell or signals for warning.  After starting, such as the discovery of abnormal phenomenon, immediately stop working and find out the reason.

Feed the crusher after its normal operation: the material should be put in evenly to the cavity.do not add material in the lateral aspect, so as not to overload the machine.

Under the normal working circumstances, bearing temperature should not be more than 30 degrees, the highest temperature should not be more than 70 degrees. Only often lubrication work can ensure the normal operation of the machine and to extend the life of the equipment. The bearing grease for the volume of the space covers around 50%, changing for every 3 ~ 6 months.

Only the two groups of hammer crusher weight equilibrium can cast the biggest efficiency, and won't attack noise. There is no absolute balance, generally speaking, the error is not beyond 5 grams, or you should be careful and change one of them to make the two equal. To finish the task of crusher needs the expansion of the high strength, which easily causes the loose of the screw cap, that is to say, all of the machine will be shocked with the expansion of the high strength. So, the screws should be tightened. Of course, the task can be finished in the common examination of machine.
