Is the debris sorting device useful for the construction waste crusher production line?


There are many sundries in construction waste, such as scrap iron, wood, glass and waste plastics, especially scrap steel and scrap iron wire in reinforced concrete. Therefore, it is necessary to recycle construction waste. For the price of a specific small mobile construction waste crusher, Xi’an construction waste subsidy is not mentioned here. Because there are a lot of debris in the construction waste, the construction waste crusher production line needs to be equipped with a debris sorting device to eliminate the influence of scrap steel and scrap wire on the performance of recycled concrete aggregate.
The debris sorting device equipped with the general construction waste crusher production line is a de-ironing device. It is recommended to use a suspended self-unloading iron remover. It is not recommended to use a manual iron remover for cost saving. The reasons are as follows: First, the iron content in construction waste is relatively high. Many, the manual type iron remover needs to be powered off for manual processing at intervals, which takes manpower and time. Secondly, the dust content of construction waste is high, which will affect the magnetic field strength and iron removal capacity of the iron remover. The suspended dump iron remover has large magnetic permeability and strong suction force. It has the characteristics of dustproof, rainproof and corrosion resistant. Reliable operation in extremely harsh environments.
The construction waste is also mixed with light materials such as bamboo wood, plastics, and woven fabrics. The construction waste crusher production line can separate these light components by sorting equipment to improve the purity of recycled materials and the reuse rate of construction waste. Commonly used are horizontal wind sorters and vertical wind sorters.
As can be seen from the above, the debris sorting device is useful for the construction waste crusher production line. If the user’s funds are limited and the processing scale is small, a simple structure and low cost fan can be selected as the simple sorting device. However, when there is a large amount of soil in the construction waste, the single-use wind opportunity affects the environment of the work area. It is recommended to use a horizontal wind sorter or a horizontal air flow sorter according to the requirements of the recycled materials.

Dust pollution should pay special attention to the wear of the jaw crusher


The jaw crusher is the first choice for the crushing of ore in the gravel production line. In the gravel production line, the jaw crusher is generally used for coarse crushing of ore. Compared with the general ore crusher, the jaw crusher can be broken. The ore is relatively hard and has a relatively large feed. Due to the harsh environment of the jaw crusher during use, the crusher manufacturer reminds the users to pay attention to it, and it is necessary to pay attention to the dust pollution problem of the jaw crusher.
In order to reduce the dust caused by air leakage from the crusher casing, in actual production, when the material is dry, water is often poured at the inlet of the crusher. In fact, this situation is wrong, which will aggravate the bag filter of the jaw crusher. The filter bag and the feeder are clogged.
During the falling process of the ore and other materials on the belt conveyor, the air enters the sealed dust hood together with the material, and the dust-containing gas diffuses outside the cover through the gaps and holes in the cover wall. In addition, due to the improper setting of the dust removal point at the corner of the belt conveyor The dust collector has almost no effect on the dust of the lower belt conveyor regardless of the opening and closing. Since the operation of the jaw crusher, the dust collector has not been operated, and the lower belt conveyor has been in the process of dust pollution.
When the crushing material of the crusher machine has a large humidity, the elbow portion is easily worn by the dust and the dust particles that are blocked into the dust collector are thicker than the broken dry material, and the bag type dust remover is easy to paste the bag, and the feeder is easy to block. As a result, the ventilation resistance of the bag filter is greatly increased, and the ventilation capacity is lowered, resulting in wear of the jaw crusher.

Analysis of Lubrication System of Cone Construction Waste Crusher


In the production process of the cone-shaped construction waste crusher, in order to reduce the impact of the wear on the parts when the parts are used, it is necessary to lubricate different parts inside the equipment. This lubrication process mainly reduces the degree of wear. To ensure the smooth operation of the equipment, and later for the better realization of lubrication, the automatic lubrication device - lubrication system is adopted, so that the lubrication operation can be realized quantitatively and quantitatively, and the protection of the internal parts of the cone construction waste crusher can be better. At the same time, good lubrication operation can reduce the occurrence of faults in production and ensure the efficiency of production. Here is to introduce the lubrication system of the machine.
In the interior of the cone construction waste crusher, the lubrication system mainly uses the oil pump to press the lubricating oil. The oil enters the lower gap of the eccentric bushing from the oil hole on the lower cover of the frame through the oil pipeline, and then is divided into two paths, respectively. For the lubrication operation of different parts of the equipment, the clearance between the main shaft and the eccentric bushing rises until the oil retaining ring is blocked and overflows to the bevel gear, and the other path rises along the gap between the eccentric bushing and the bushing, and the thrust ring Also enter the bevel gear, so that the bevel gear lubricant is discharged through the drain pipe. The suspension device of the construction waste crusher is softened by dry oil, and the oil is pressed into the dry oil by hand pressure. In this process, the three collars of the lower part of the equipment must be sealed to prevent dust from entering.
Through the analysis of the internal lubrication system of the cone construction waste crusher and the realization of the lubrication process, it can be found that in the interior of the equipment, the lubrication system realizes the lubrication of most parts, and the lubrication process can be autonomous. Realization, no need for manual operation, just need to refuel regularly.
In addition, in the process of using the construction waste crusher, in order to better realize the lubrication effect, it is necessary to periodically clean the system to prevent dust from entering, to prevent the lubrication failure caused by the pollution phenomenon, and then to lubricate. The choice of oil should also be cautious, the right type of lubricant can double the lubrication effect.
The article mainly introduces the analysis of the lubrication system of the cone-shaped construction waste crusher. It is mainly about the introduction of the lubrication system, the lubrication process, and the analysis of the problems that should be paid attention to when lubricating. Good lubrication is to achieve good machine waste for construction. Important conditions for the process.

Self-balancing advantage of impact crusher


During the working process of the crusher machine, the deflection of the hammer head will change the mass distribution of the rotor, the wear of the hammer head and the adhesion of the mineral, the original imbalance generated during the design and manufacturing process, etc., which will cause the crushing machine to be unbalanced, resulting in equipment. Vibration and reduce the life of the equipment. The impact crusher is structurally very similar to the automatic balancing device of the centrifugal vibrator and therefore self-balancing. The following is the research and analysis of the self-balancing phenomenon by the crusher manufacturer experts.
The principle of the automatic balancing device of the centrifugal vibrator of the impact crusher is to utilize the automatic centering principle of the rotor. Taking an automatic balancing device with two vibrators as an example, each vibrator can be rotated about a hinge point. In the case of no eccentricity, the vibrators will be arranged in the radial direction under the action of centrifugal inertia, and the vibrator will not be balanced or eccentric. In the case of eccentricity, when operating at an excessive critical speed, the position of the vibrator is far from the center of the vibration, which reduces the original eccentricity, thereby achieving balanced vibration reduction. Operating at subcritical speeds exacerbates the degree of eccentricity and increases the amplitude of the vibrating subsystem, which is detrimental to the system. One of its discs is equivalent to an automatic balancing device with six vibrators. When operating at over-critical speed, the vibrator will reduce the original imbalance, which reduces the vibration of the system, which is extremely beneficial to the system. When operating at subcritical speeds, the automatic deflection of the hammer will cause the hammer system to generate large vibrations. In the design of the impact crusher, it should be in an operating state of excessive critical speed. If it is operated at an excessive critical speed, a large vibration peak (resonance) will occur during start-up and shutdown, so the critical speed value can be determined by a simple experimental device. Therefore, at the time of design, it can operate at an excessive critical speed, which can play the role of automatic balance damping, which also provides a great reference value for how to realize the vibration reduction of the crusher rotor system.

The order of opening and stopping of vertical mill, the application range of Shanghai vertical mill in the field of industrial milling


The vertical mill is no stranger to everyone, because its application is really wide. The operation of the vertical mill is also very simple, but it has its own order of opening and closing, you know, let us take a look.
Vertical mills are widely used in cement, building materials, electric power, metallurgy, chemical, non-metallic minerals and other industries for the grinding and ultra-fine grinding operations of various solid materials.
Although the operation of the vertical roller mill is not complicated, there are some things that we should abide by, such as the sequence of operations. Let’s take a look at the sequence of the vertical mill.
The vertical mill starts and stops in sequence:
The mill starts first, the oil level valve position should be in place; the material of the material bed needs to be paved enough, and it is ready to be inspected again; the oil road waterway is unblocked, the oil station filter plug is not blocked; the tension pressure is not enough, and the pressure of the door is not enough. The mill looks at the system, the host must be coherent before and after; the raw material warehouse is full of dissatisfaction, the raw material warehouse is not empty; notify the inspection to see the scene, the front and rear auxiliary machines can be normal.
Check it can be turned on, the boot sequence should be understood; follow the logistics reverse, after grinding, the auxiliary machine is first opened; after grinding, the auxiliary machine is normal, then open the main machine vertical mill; how to open the mill, first open the oil pump; First, low pressure and high pressure, then open the sealing fan; after 10 minutes, the large fan, beyond the clutch and then connected; auxiliary motor to transition, then open the main motor; raw material delivery to keep up, to prevent empty grinding less danger.
Normally, the monitoring data should be carefully observed; the various parameters should be remembered in the heart, and the comparative analysis should be regular; if there is no need to panic, the calm processing will be appropriate; the order of shutdown is reversed, and the logistics stop to the end; the host stops without urgency. The oil pump stops slowly for three or five minutes; after the circulation fan stops, it seals after ten minutes; cut off the power supply and water source, and record and clean.
The above is the jingle of the vertical mill during the start-stop process, which is very easy to understand and provides assistance to the frontline operators.
The vertical mill is a mechanical device with a very simple working principle. It is the leader in the grinding industry. The vertical mill is destined to be a miracle.

Exploration on the future development mode of impact crusher manufacturers


In the crusher equipment industry, Western powers have clearly promulgated national standardization strategies and invested a lot of resources, while domestic is dwarfed. impact crusher manufacturers we can’t get up early, catching a late episode. At present, most of China’s national standards lag behind the international level. The international standards adopted are mostly ISO and IEC standards formulated in 1994 and before, and many have fallen behind or been eliminated. The standards set by China are not recognized internationally, and they are all non-critical standards. In most cases, China can only passively enforce foreign or international standards and has to be subject to people. In this regard, China should take advantage of its huge market and do my job as a landlord. Everything that comes to China must comply with Chinese standards, or else. China is already the world’s largest and fastest-growing crusher market, and we have no reason not to set its own international standards, rather than arbitrarily at home.
With the rapid and steady development of the national economy, the foundation of the national economy & mdash; & mdash; mining machinery industry has also grown and began to take the international road. However, the nationalization road is not a few overseas big lists called internationalization, but to achieve overseas localization, it is considered international. The ideal state of operation is that without the participation of Chinese personnel, overseas subsidiaries can still operate successfully. But this is not a simple matter. It requires a large number of talents to be trained. A lot of communication in the early stage, coordination of local social habits, customs, local local engineers, technicians, managers, etc., instead of relying solely on domestic airborne .
