Key Points of Selecting Bag Filter
Bag filter is a dry dust filter equipment, mainly used for cement, metallurgy, building materials, machinery, chemicals, power and other industries flue gas purification, dust treatment (non-fibrous) and material recovery. The core part of the whole dust removal work is installed in the box inside filter bag, filter bag with a textile filter cloth or non-woven felt made when the dust through the air inlet into the fiber fabric filter of the dust collector, the particles in the gas are filtered, in which the particles are larger and larger dust, due to the role of their own gravity down, fall into the hopper, small dust particles in the gas through the filter bag is blocked, so that the gas is purified specified emission standards. For different production conditions generated by the dust-laden gas, to choose the appropriate type of dust collector for purification, so as to achieve the best purification effect, if the equipment is too large, will cause unnecessary waste, if the equipment small, will affect the production, not meet the environmental requirements. The main selection is based on the following: 1. The temperature of dust-laden gas Dust gas temperature is the main basis for the selection of dust, if the intake air temperature and design temperature deviation, will cause serious consequences. When the gas temperature is too high, the filter bag will burn and deform. For high temperature gas, it must be cooled to below the temperature at which the filter can withstand. If the gas temperature is too low, condensation will occur. Therefore, the gas temperature must be kept above the dew point of 20 ℃. 2. Handling air volume Processing air volume is the amount of dust that the purge can purify the gas per unit of time. Units are cubic meters per hour m3 / h or standard cubic meters per hour Nm3 / h. This is one of the main basis for the selection of dust collector. 3. The entrance dust concentration Refers to the air inlet dust concentration, which is determined by the dust point of the production process, in the selection when it is second only to deal with the air flow has an important factor, the unit is g / m3 or g / Nm3. When the inlet dust concentration is too large should be considered to add pre-dust removal equipment. 4. Export dust concentration It is the discharge concentration of the precipitator, which is mainly determined by the local environmental protection requirements and the requirements of the user. The exhaust emission concentration after the dust treatment is generally 50 g / Nm3.

PYB series cone crusher for cobblestone
The smooth surface of the cobblestone is a natural wealth to the human, in addition to decorative, the cobblestone through special equipment can also be broken after the concrete production of raw materials, successfully applied to the highway and urban construction industry. According to market research, pebble crushing equipment market is the most widely used in cone crusher. After a large number of experiments show that, through PYB cone crusher crushed pebbles set with pebbles and artificial gravel double advantages, can greatly improve the physical properties of concrete products to improve the pumping cement concrete shrinkage and the characteristics of cracks, with higher economic and environmental benefits, known as the "green building materials" As a result of the extensive use of river sand (natural sand) to build houses, over-exploitation led to a large number of depleted resources, people have to consider the use of pebbles to make sand, pebbles as raw materials made of cement concrete advantages, such as pebbles easy to crush, sand molding is good, high strength, a variety of performance can replace the natural sand. At the same time, with the rapid progress of the highway and urbanization process, the construction industry has developed by leaps and bounds, and the demand for construction gravel is increasing day by day. However, due to uneven distribution of rock and pebble geographical resources, artificial gravel, pebble shortage, and cobblestone has become another choice of building material. In order to meet the demand for pebble raw materials in the concrete market, PYB cone crusher is developed based on laminated crushing principle and conceptual design of [more crushing and less grinding"; thus this new type of cone crusher – Hydraulic cone crusher is integrated with high wobble frequency, optimal cavity shape and reasonable stroke. This series of efficient cone crusher has more reasonable and perfect structure and more advanced technology.

Factors Affecting the Efficiency of rock crusher machine
Rock crusher machine is one of the important mechanical equipment in the mining machinery. The rock crusher machine is the effective equipment for the broken ore. Because the environment of the dressing equipment is harsh and the working time is long, so the damage to the crushing machine equipment will be great and lead to replace parts more frequently. Different regions, different manufacturers of rock crusher quality is also different, good quality rock crushers certainly have longer life, then how to choose them? For example, jaw crusher is the first crusher on the stone production line and is a very important crushing device. When the user chooses the rock crusher to determine his or her own material, the model is selected according to the output, the production capacity and the material properties. When we choose the types of crusher model specifications, need to choose a group of both strength and good reputation of the manufacturers to conduct field visits, choose crushed stone machine to see the crusher are made of steel, because the crusher working environment is bad, every day to expose the weather, choose raw materials equipment. Finally, the user must do the machine maintenance and maintenance work, as a professional manufacturer, we can provide you with professional and detailed rock crusher models. In addition, as a common crusher equipment, crushing efficiency of rock crusher is high, low production efficiency, directly related to the economic benefits of enterprises, so to ensure that crusher crushing efficiency is necessary. Crusher crushing efficiency is generally refers to the unit time crusher production, commonly used standards can measure the number of tons per hour or daily production, crusher crushing efficiency is related to the following factors: First of all, the material factors, including the hardness of the material, the temperature and other hard materials broken more difficult, the more serious wear and tear equipment, the material temperature is likely to cause crushing within the crusher, or blocking punching, affecting crushing efficiency. Second, the product fineness requirements. The product fineness requirements are higher, crushing efficiency is low. Again, the phenomenon of crushing. The more serious crushing phenomenon, the lower efficiency, on the other hand, the production of atomization effect is crushed by powder bonding machine production, affecting processing efficiency. Finally, the rock crusher's own performance. The dynamic design of the crusher, the structural design and the wear resistance of the material have a strong impact on the crushing efficiency of rock crusher machines.

Ball Mill for Mineral Processing
Ball mill is a kind of mineral processing equipment, and is also very important grinding equipment, its presence and usage for the entire dressing production line is very important. There are many users for the use of ball mill, is not very understanding, resulting in a lot of unnecessary mechanical failure. How to avoid such a situation, the methods as follows: In the use of ball mill, what are the needs to pay attention to the places? 1. The size of the output Ball mill in the grinding of different objects, we can according to the nature of the object to choose the size of its output. When the ball mill in the best state of operation, it is best not to change the output. If the output is too small, it will cause the ball mill overload, resulting in ball mill current increases, reducing milling efficiency, and even endanger the use of equipment safety. 2. Fill the ball volume In the course of ball mill running, due to wear and tear, steel balls weight and diameter are constantly decreasing, so we need to regularly fill the new ball. As for the determination of the amount of balls, we need to wear rate and the amount of coal to determine the ball. 3. The nozzle size The size of the nozzle diameter adjustment will affect the concentration, flow through the ball mill water, the system cycle magnification and so on. Therefore, in order to keep the ball mill in the best running condition, the nozzle size is usually not adjusted. 4. Limestone particle size If the limestone particles is too large, it will put an additional burden on the ball mill, and individual large limestone particles are not easily broken by steel ball, which not only reduces the output of the ball mill, but also increase the power consumption of the ball mill. Therefore, in the design of its time, to ensure that the limestone into the ball mill size is below the maximum size of the design. The above points are needed in the use of ball mill in the process of attention, ZK Corp hope that each ball mill users can understand clearly, so that equipment for your better service.
