Components Introduction of the Cement Mill

It is known that cement mill is the key equipment used to re-crush the materials . This mill is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, black and non-ferrous metal processing , glass ceramics production, and the other industries.
The mill components:
1. Cylinder
This machine is the horizontal cylinder rotating device, and mainly composed of cylinder mill door, liner bolts, the most important failures of the cylinder are bolt leakage gray mill gate leakage gray, barrel bending, in view of the cement mill temperature , rarely occur the cylinder bending phenomenon, but the cement grinding is relatively thin , cylinder bolts and mill door drain gray phenomena often appear. To this end, we are required to arrange the cylinder mill door fastening work  at any time when the mill shuts down.
2. Liner
Liner is used to protect the cylinder,and avoid damage of the long-term impact and friction cylinder,we can also adjust the motion state of the material in mill. When checking, we mainlycheck the liner wear condition, whether the liner bolts are loose fall or not to avoid  liner's excessive  wear, because this wear can result the material changes in the state of motion and reduce cylinder life.
3. Compartment plate
Compartment plate is mainly composed of center circle compartment plate, stock guide cone, grate plate, lifting plate, lining, compartment plate bracket, blind plate. When checking ,the main work is to check whether the compartment plate bolts loose, fall, each grate is intact, grate seam is clogging the grate plate and blind plate excessive wear, cracks compartment plate bracket, whether the impact of the grate plate , string ball phenomenon or not.
4. Main bearing
Bear the mill rotary part quality and impact of the grinding media , the mill  support on the main bearing through the hollow shaft , the bearing housing is equipped with bearing cap, observation hole (observation of oil supply and the control shaft, bushing functioning), the thermometer of the temperature measurement. The bearing lubricant adopts hydrodynamic lubrication and hydrodynamic lubrication these two methods, dynamic pressure use the low fuel supply, duo to the mill speed is low, the oil film dynamic pressure formed is thin,can not reach the effect of liquid friction and lubrication, so the hydrostatic lubrication is adopted, specifically set of high-pressure oil pump for high-pressure oil to the oil bag, rely on the pressure of the oil to form a thick film. In the normal operation, the static pressure lubrication, hydrodynamic lubrication still work automatically, when appears the static pressure problems, the dynamic pressure. The general bearing liner allowed temperature does not exceed 70 °.  if the bush-burning phenomenon occurs, we must take the cooling method.

Ignition Operation Issues of the Rotary Kiln

 It is known that the rotary kiln refers to rotating calcining kiln (commonly known Xuanyao), belongs to the class of building materials equipment.  according to different materials, Rotary kiln can be divided into cement kiln, metallurgy chemical kiln and lime kiln. The cement kiln is mainly used for calcining cement clinker  in cement kilns , which can be divided into dry and wet process cement kiln these two categories, Metallurgy chemical kiln is mainly used in metallurgical industry, steel plants depleted iron ore magnetic roasting; oxidizing roasting of chrome, nickel, iron; the Refractory Plant roasting high alumina of vanadium bauxite and aluminum roasting clinker, aluminum hydroxide; chemical plant baking chrome ore and chromium ore and other minerals. Lime kiln for roasting (ie, active lime kiln) steel plant, ferroalloy plant with active lime and light burned dolomite.
Ignition is the first step of the fired rotary kiln system production ,whether in the operation of the new production line , or the maintenance of machinery in production process, lining replacement or trouble parking, the ignition operation are all required to carry out, that is the initial coal injection combustion.
The following briefly describes the rotary kiln ignition notation:
[1] First start the kiln inlet main exhaust machine, adjust the air intake valve, pull the kiln and piping system wind about 5 minutes, reduce the concentration of carbon monoxide in the kiln system,makes it full of fresh air, while close the kiln inlet access doors .
[2] before rotary kiln ignition  spraying, we need to adjust the pulverized coal burner position and status , the distance between the general coal injection nozzle and the kiln mouth is about 0.5 m, we also need to adjust the coal burner channel interface to the relatively larger, make the starting flame early soft and smooth , the fire was concentrated,so the pulverized coal easily ignited.
[3] before the ignition, we should be sure to open the appropriate degree of the preheater ignition breathing apparatus. It is best to get the central control for the convenience of adjusting .but due to the preheater temperature is high, kiln pumping force is large,which is adverse to the early coal combustion , so we need to control the kiln wind speed by depressing breathing apparatus.
[4] spray pulverized coal before the on-site testing, this is mainly to ensure the smooth flow of pulverized coal injection piping system, the pulverized coal scales Gongmei control is reliable. The test spray time should not be too long, about 2 minutes, but we should contact with the  on-site staff  timely, stopping spraying immediately after confirming the coal powder.

Details of Selecting the Appropriate Dryer

When the user purchasing the drying equipment (dryer machine), it is necessary to select them, the following is the several details need to pay attention in the selecting process of dryer (dryer machine) :
 First, corporate site visits
We should first examine the drying equipment manufacturers,  observed the attitude of the Factory, on this basis, we can get a preliminary environment understanding and the productive capacity of the plant. Learn whether this plant have laboratory equipments or not, whether have materials experimental data or not,the  experimental results of materials. We should seriously listen to the phenomena of the factory report, understand its manufacturing capacity, whether the drying equipment manufacturers processing means meet the requirements, listen to the processing method type statement of the drying equipment manufacturers  .
Then,  see whether the enterprise have an existing production site or not
Level of drying equipment manufacturers depends to some extent on the performance of its work, under normal circumstances, the more work performance equipment manufacturing capacity, the stronger their equipment manufacturing abilities, because the manufacturing equipment technology can make the equipments more excellent. If the manufacturer is the first manufacturer of this model,then the user must be cautious, the serious argument to its technology maturity is necessary.
As to the credibility of the enterprise,we can also get from its customers .
Nowadays, the society after-sales service is an important indicator to measure products. The drying equipments are required to maintenance regularly, in the process of operating the machine, some problems that are different to solve may appear sometimes,  whether some wearing parts have generality or not, whether the plant can provide users with permanent technology consultation, spare parts or not , these are all questions need to take into account when selecting the dryer machine manufacturers. We need to inquire the dryer machine manufacturers and their users to learn the enterprise credit and their actual after-sale situation, thus can efficient avoid the unnecessary economic loss.
Finally, examine the drying effect of the same or similar materials , if the further investigation are carried out, it is best that the drying equipment manufacturers can provide the same material drying experience, so that the credibility of this project can be efficiently increased . It is proved that carry out the situ experiments, the situ testing equipments are important basis to increase the purchasing confidence of customers.
We hope the above suggestions are helpful.

Different Classification Methods of Magnetic Separator

As we all know, the magnetic separator is widely used in resource recovery, the timber industry, mining, ceramic, chemical, food and other industries,  it is a kind of model that used widely in this industry.
Many different types of magnetic separator have been used at home and abroad, of course, there are many different classification methods.
1. According to the magnetic source , they can be divided into the permanent magnetic separator, electromagnetic separator;
2. according to the magnetic field strength, they  can be divided into:  (1) weak magnetic field magnetic separator, the magnetic pole surface magnetic field strength H0 = 72-136 kA / m ,the magnetic force HgradH = (2.5-5.0) 1011 Ann 2 / m 3; (2) medium magnetic field magnetic separator, the pole surface magnetic field strength H0  = 160-480 kA / m; (3)strong magnetic field magnetic separator, magnetic pole surface magnetic field strength H0 = 480-1600 kA / m, the magnetic force HgradH = (1.5-6.0) 1013 Ann 2 / m 3;
3. According to the sorting process medium,they can be divided into the dry magnetic separator, wet magnetic separator (wet magnetic separator);
4. According to the magnetic field type ,they can be divided into a constant magnetic field, a pulsating magnetic field and an alternating magnetic field magnetic separator;
5. According to the body structure shape, they can be divided into belt magnetic separator, drum magnetic separator, roller magnetic separator, disc separator, ring-type magnetic separator cage magnetic separator and pulley-type magnetic separator.
6. We can also distinguish them through the magnetic field strength, sorting medium and structure type.
Weak magnetic separator (magnetic separator) is mainly used for election do strong magnetic minerals, such as magnetite, titanomagnetite, ferrosilicon.
In the former industrial, the electromagnetic magnetic system is adopted widely, the body shapes are always appears as drum and belt type. At present, the magnetic system and cylindrical type are widely adopted, and wet applications are more.
In the strong magnetic field magnetic separator of the early earlier years, the dry type magnetic separator whose separation size is coarse can be used to select the Non-ferrous metals and rare metals minerals.
Over the past decade, in order to select the ore whose grade is low and dissemination is fine to form the weak magnetic mines, we have developed a variety of wet high intensity magnetic separator, such as ring, cage, disc, most of them are still in the experimental stage. The medium magnetic separator is mainly used for sorting the strong magnetic ores that oxidated locally.

Purpose and Principle of the Third Generation Sand Maker

Chinese Sandstone Association clearly pointed out  that: the excellent artificial sand quality should be --- reconcile sand / artificial sand / powder / mud / natural sand / the weathered sand / tailings reconcile sand. At present, due to the considerable demand for artificial sand, some enterprises which do not have the quality of producing sand began to use the simple   making machine to produce sand ,of course, the sand they produced is unqualified, which not only cause the user to pay a much greater cost than usual, the more serious is the  concrete produced can not achieve the requirement, this directly impacts   the quality of the construction work. The following is the third generation   maker which is truly suitable for the production of artificial sand:
 The application of the third generation sand make machine (sand-making machine) :
This series of sand makers applies to the soft , medium hard and extremely hard materials crushing, plastic, which is widely used in a variety of ores, cement, refractories, aluminum where the soil clinker, emery, glass raw materials, mechanism building sand, stone, and each kinds of metallurgy slag, especially for silicon carbide, silicon carbide, sintered bauxite, sand US high-hard, especially the hard and the other corrosion-resistant materials . In the engineering industry ,it is the ideal equipments of producing mechanism sand, cushion material, asphalt concrete and cement concrete aggregate . And so on. In the mining industry, this product is widely used in the preceding grinding process, it can produce large amounts of iron ore fines, reduce the high cost of grinding load. As the   excellent low wear characteristics of this sand maker , this series device is also used for high abrasive and secondary disintegration crushing production. In addition, due to the zero pollution to production,  crusher can well adapted to the production of glass quartz sand and other high purity materials , in the scale off10-500t / h production capacity  , this crusher can meet almost any production requirement.
The working principle of the third generation sand making machine (sand-making machine) :
The material is fed from the feed hopper to the crusher, and be divided into two parts by the sub-feeder, part of them go through the middle of the sub-feeder into the high-speed rotation of the impeller,  being rapidly accelerated in  the impeller,  its  acceleration gravity can achieve to several hundred times, and then projectile out from the impeller three runner uniform at the speed of 60-70 m / s, the first part of the same sub-feeder four weeks from the closing falling material   crusher, and with the impact of the vortex cavity lining materials material lining rebound oblique impact to the top of the whirl chamber, and then change the direction of motion, deflected downward movement of material emitted from the impeller form a continuous materials curtain. In this way ,the material  be crushed ,fracted and grand in the   whirl crushing cavity   twice as well as several times  . The broken material is discharged from the lower part of the discharge opening. During the whole crushing process, the materials are impacted crushing to each other, don't   contact with the metal components directly but with the lining materials shock,  in this way,   the pollution angle is reduced,  the time of mechanical wear is extended.
