China is rich in coal resources, with many reserves and a wide variety. Coal accounts for more than 75% of China's energy, and is the most important energy source in China today and in the next few decades. With the increasing degree of coal mining mechanization in China, the coal content has increased, the moisture of raw coal has increased, and the quality of coal produced has deteriorated. In China's proposed clean coal production strategy, coal washing is the leading, so the development of coal washing and processing industry is an important measure to improve the quality of coal.

Mine banana creen has many different ways of classification, for example, according to the trajectory can be divided into linear screen, circular screen, high frequency screen, banana screen. How should we solve the problem of slow discharge of banana screen? Don't worry about this, here's how

In order to ensure the safety of personnel and production needs, a regulating wall is built in the mine and a regulating window is opened in the belt conveyor cover. According to the needs of mine transportation and ventilation, part of the transport belt has to pass through the regulating wall. When the wind flow passes through the belt hole of the regulating wall, the wind speed through the belt hole will become bigger because the ventilation section suddenly becomes smaller. During the experiment, the utility modeler found that if the hard wind shield was used, the coal on the belt conveyor

Why should I use a Mineral Sizer over a Jaw Crusher, Gyratory Crusher or Impactor? A Mineral Sizer offers a more effective means for crushing clay-ridden sticky material, eliminating the need for recirculation of oversized material as produced by Jaws, Gyratories or Impactors. Mineral Sizers have a lower capital cost than other primary crushers as well as a lower infrastructure/structural cost.

Apron feeders is one of the feeding equipment in material crushing system, divided into heavy duty, medium duty and light duty, and now the common one is heavy duty. Heavy apron feeders is suitable for short distance conveying materials with large capacity and particle size, also can be used as a buffer bin to feed the primary crusher, can continuously and evenly feed the next process, can withstand large bin pressure, it is characterized by large feeding capacity, low speed and high torque.

As a traction component of the apron feeders, the chains plays an intuitive and important role in the normal use of the equipment . As a common spare part, the use of the equipment also has a service life, so after the service life of the chains need to be replaced, so what are the considerations for the replacement of the apron feeder? The following are detailed explanation:

In the production of coal gangue sintered brick, apron feeders is widely used in the raw material transportation and preparation system. It is characterized by high transportation pressure and uniform feeding. It can also be fed by adding motor frequency converter, so as to realize the stepless control of feeding amount. However, after years of use, it is found that the stability of the apron feeders needs to be improved, which is manifested in the deformation of the loading plate and the bearing shaft under the impact of the material, which can cause mechanical accidents. Therefore, we makes

Mineral sizer is a new generation of environmental protection, high efficiency and energy saving type crusher independently developed by our company. Mineral sizer is suitable for coal, mining, metallurgy, chemical industry and other industries, the coarse and intermediate crushing of brittle massive materials, because the machine uses the crushing principle of shear and tensile, and the use of optimized tooth shape and microalloyed high chromium iron material, can be broken material strength below 200Mpa brittle rock.

Mineral sizers is a kind of high efficiency breaking equipment, which is widely used in breaking operation in coal and chemical industry. The roller teeth are the main working parts and are in direct contact with the material. Therefore, the quality of roll tooth design is directly connected to the production efficiency and service life of the mineral sizers.

Main Problems of the Mineral Sizer at Present are the transmission type is backward and the open long tooth gear is adopted to ensure that the transmission of the movable tooth roller will not be interrupted when it retreats.

Belt conveyor is a friction-driven machine that transports materials in a continuous manner. It is mainly composed of frame, conveyor belt, rollers, rollers, tensing device, transmission device， Conveyor cover and so on. It can form a kind of material conveying process between the initial supply point and the final discharge point on a certain conveying line. It can convey both scattered materials and finished goods. In addition to pure material conveying, it can also be combined with the requirements of the processes in the production process of various industrial enterprises.

Mineral sizers are mainly composed of a gear box, a frame where the breaking plate with teeth is the main part of the fixed stick, a fixed roller, a movable roller and a linkage device. The teeth breaking plate is in direct contact with the ore, which requires a high hardness of the teeth breaking plate. Therefore, the breaking plate with teeth is made of chromium-containing high manganese steel, and is treated with water toughness after casting.

Now many factories and workshops will use belt conveyor , and some are used in outdoor equipment to be eroded by rain for a long time, but some of belt conveyor have already been installed conveyor cover, because of the help of this tool, avoid many equipments damage.

Generally ,Apron feeders can been divided into heavy, medium and light type, it is the commonly used feed mill equipment,Widely used in mining, processing plant, chemical industry, cement, building materials and other departments,Used for uniform continuous feeding from storage bin to crushing, transportation and other machinery.

he actual water content of the feed does not match the information provided in the technical contract; if the water content is too high, the material will become wet and sticky, making it easier to adsorb to the equipment. Because in the dump truck from time to tome a lot of falling objects, in both the top and bottom of the hopper outlet installed spray dust suppression agent, to prevent a lot of dust and protect the working environment, when the conveyor belt system is running, spray dust control unit will spray a large amount of water mist, this will increase the material's surface water a
