For the use of ultrafine mill, only if it meets the production requirements can it be accepted by customers. The production requirements do not only refer to the performance of the machine, but also include environmental protection. The concept of environmental protection is near It has only been proposed in recent years to reduce environmental pollution and protect people's living environment. It has been valued by various industries. Therefore, only by meeting this demand can good development be achieved, and in order to meet this environmental protection requirement, The manufacturer configures the dust collector for the ultrafine mill. Here we introduce the performance characteristics and working principle of the dust collector.
First, performance characteristics
For the ultrafine pulverizer, it is specially developed based on the characteristics of the machine's fine and dry dust. These dusts are captured during production. Generally, the precipitator uses pulsed ash cleaning. The method has the characteristics of good effect, high purification efficiency, long life of the dust removal filter bag, small maintenance workload, safe and reliable operation, etc. These characteristics make the dust removal equipment have a wide range of use.
The performance characteristics of the dust collector used in the production of ultrafine mills are as follows: the use of advanced on-line pulse injection technology, thorough ash cleaning, and low running resistance; the use of high-quality dust collector accessories, effectively guarantees high efficiency Dust removal efficiency, and fully automatic control, convenient maintenance and high operating efficiency.
Second, how it works
In the production of ultrafine mill, the working principle of the dust collector is as follows: The air inlet of the dust collector is connected with the air outlet of the ultrafine powder equipment. Dust-containing gas enters the ash hopper through the air inlet on the side of the box. When the deflector is turned to the dust bag chamber, the coarser particles fall directly to the bottom of the ash hopper, and the fine dust rises with the airflow. When the airflow passes through the filter bag, the dust is blocked on the surface of the filter bag, and the purified gas passes through the dust removal. The cloth bags are collected in the clean air box, and then discharged into the clean air exhaust channel by each air outlet butterfly valve.
The article mainly analyzes the dust collector of the ultrafine mill, mainly for its performance characteristics and working principle analysis. In modern milling or crushing production, the dust collector has become an indispensable part. For various types of production The environmental effect of the process has played a significant role, and according to the different production processes, different dust removal equipment can be selected.

The ultrafine mill itself is a kind of better performance equipment, so it has a wide range of applications, but its performance needs to be used in a standardized way, such as the way of operation and regular maintenance, and more importantly, it cannot be overloaded. For production, how many hours a day is it better for this type of equipment?
Generally speaking, when the machine is shipped from the factory, there will be a description of the use, which will strictly indicate the way of use, including the length of use, for the type of production equipment of the ultrafine mill, because it is for The processing of ore materials and production conditions are also very difficult, so generally we do not require more than thirteen hours of work in the production line, and during this working period, we need to carry out better maintenance to ensure smooth production and The machine is not damaged.
ultrafine mills may change in working hours in different climates, because winter needs to be warmed up and summer needs to cool down. This is some of the conditions that will affect their work. We need to make different according to different situations. Processing to ensure that it works safely.

In the production process of mines, whether it is grinding machines or crushing equipment, their requirements for production conditions are strict. If they cannot meet the production requirements, they will lead to a decline in production efficiency. One of the requirements is The feed is pure, let's analyze the problem below. Raymond Mill is one of the mills. Because it is a device for producing fine powder, the demand for feeding is more strict in the production. The main requirements are the hardness, humidity, size and input of the material. The speed of the material must meet the production requirements, and the purity of the material, which means that it does not contain other non-manufacturable foreign materials, such as iron blocks and other materials that cannot be processed, so why does the Raymond mill have this aspect? What is the demand?
For crushing or milling equipment, non-processable materials are foreign materials, which cause great wear and tear on the parts of the equipment during production, increase the aging of the parts, increase the frequency of maintenance in production, and improve the production efficiency. In terms of it, it is very unfavorable, so it is necessary to strictly prevent the entry of these foreign objects in production. Some Raymond mills have a better degree of automation, so they can discharge foreign matter without affecting production, but more fundamentally. The solution is to prohibit the addition of these materials better.
The above analysis of the reason for the purity of the Raymond mill is mainly to prevent the wear of foreign materials on the parts, which can prevent the decrease of efficiency and the increase of maintenance cost. It is an important operation, and some equipments. These materials can be automatically discharged, but it is more fundamental to prevent the addition of these materials. Read more...

The ore grinding process is to grind large chunks of ores into reasonable particle size, so mineral processing mills are essential. The common grinding mills are ball mill, pebble mill, ultrafine mill, etc., all belonging to ore grinding equipment. There are many types of mineral processing mills and the most common at home and abroad are ore dressing mill, mineral processing mill, autogenous mill, semi-autogenous mill and rod mill.
The former four types are conventional grinding mills, by which the ores can shrink to 10 to 25 mm large through two or three stages of breaking and then be fed into the ball mill or rod mill and continue to be ground to the required size. The production practice shows us that each process has its own advantages and disadvantages.
The autogenous mill is one of the most widely used equipment in ore dressing plants. Its biggest characteristic is that the newly mined raw ores or the materials after coarse crushing can be directly sent to it for grinding. When the autogenous mill is at work, ores of different particle sizes are driven by the cylinder wall to do rolling motion. This autogenous mill is a piece of multi-function equipment with both crushing and grinding effect, and it has a big crushing ratio, a dozen times higher than the equivalent ball mill and rod mill.
In the or grinding course of autogenous mill, ores larger than 100 mm can act as the grinding media, while those ores smaller than 80 mm and larger than 20 mm are of poor grinding ability and they selves are not easy to be ground by the large ores. To grind this part of materials, some big steel balls are usually added to the materials, which greatly increases the grinding efficiency. So this type of mill is called semi-autogenous mill. The semi-autogenous mill belongs to cylindrical grinding machine, characterized by heavy load, low rotating speed and large starting torque.There are still many other common mineral processing mills, such as ball mill, rod mill, attrition mill, vibrating mill, jet mill, and so on.

The biggest disadvantage of impactor breaker is easy abrasions of plate hammer and impact plate. Especially when crushing hard ores, the abrasion will be more serious, so that these spare parts need regular change. To prolong the service life of impactor breaker, it is advisable for customers to know some maintenance techniques available for China impact crusher.
1. After a new impact crushing machine is put into use, a comprehensive check should be carried out on the breaker machine every time it completes a shift. After running for two weeks, the comprehensive check can be carried out every month. The electrical machine and lubrication of this breaker machine should be carried out every week, and the check content includes the fastening condition of the fixed parts and belt drive, bearing seal and electric switch.
2. Check the abrasion condition of the spare parts such as plate hammer, impact plate and lining board every week and establish regular maintenance and change system combining with the maintenance cycle.
3. When the rotor is running, the gap between rotor and impact board can never be adjusted.
4. To guarantee the safety of operators and equipment, it is forbidden to repair, adjust and clean the equipment in the running process and forbidden to open various small doors.
5. Feed materials into the breaker machine after it normally operates, and the feeding process should be even and iron and other hard materials should be prevented from mixing in the raw materials. When stopping it, first stop feeding materials to wait until all the materials inside the crushing chamber are crushed, and then the electric motor can be stopped.
5. When product granularity of materials to be crushed are too big, SBM reminds you to stop the China impact crusher machine and check the abrasion condition of the plate hammer to prevent rotor from being abraded. Read more...

The accessories are the important part of impact crusher, which needs regular replacement. The accessories are also known as wearing parts if vertical shaft impact crusher, which mainly include plate hammer, side protecting plate, back plate, square steel and pressing block, which is made of high chromium and high manganese wear resistant materials.
1. Plate hammer: plate hammer adopts high chromium alloy materials and the latest manufacturing technology, which has unique structure and design. The finished product is in cubic shape with no tension and fracture. It is the high wear resistance casting component. When the plate hammer wears to a certain degree, it should be timely adjusted or changed, so as to avoid the injury of fasteners and other parts.
2. Side protecting plate: side protecting plate is an important vulnerable component of impact crusher. It will be worn after long term using, and its resisting ability will decline, thus often causing the accident and the decline of its sealing performance. Therefore, much dust will be generated.
3. Impact plate: impact plate is generally welded with the steel plate. The back surface is provided with a wear-resistant lining board, which also can use the counter roller or grate board with a slot of the back surface. The fine content of the product is less, at the same time; the production capacity can be increased. It is energy saving, but it also has other defects, for example, the structure is complex, the back surface is hard to replace after being worn, fast abrasion, etc.
4. Square steel: square steel is in square shape, which can be divided into welded and seamless types. Seamed steel is welded by steel plates to make square steel tube. Seamless steel pipe is formed by seamless steel, and its compressive capacity is far greater than the seamed steel.

In recent years, the feeding system of ball mill has been improved. During the past few year, the majority of the ball mill spoon head is the united feeder, because the spoon head is clumsy and eccentric, and when digging and sedimentary ore, it has friction and impact, the eccentric load and shock load of the ball mill will produce periodic, the motor operation under variable load condition, not only the capacity will be increased and current fluctuation will be large, but also will lead to the acceleration of rendering half cycle and the deceleration transmission of the half cycle. The eccentric load and shock load has great impact on the main bearing wear, gear stress, the size of the connecting bolt, barrel meshing and motor heating, which will shorten the service life of ball mill.
By adopting the drum feeder, it can avoid the above drawbacks, but we also need to transform the return system of classifier, extend the classifier groove, adjust the installation angle, so as to change the distance between ball mill and classifier. Increase the automatic return body in the upper end of the upper ore discharge from the classifier. With the help of return launder, elevation and ore gravity, the ore will flow into the feeder. The ball mill after transformation will not only improve the equipment reliability and maintainability, but also has obvious energy saving effect. Read more...
