Under the impact of the ore, the apron feeder chain plate and its supporting mechanism are deformed, which makes the apron feeder bearing damaged frequently and the maintenance rate is very high. In this paper, the dynamic and static simulation analysis of the ore impact support mechanism (composed of channel steel and I-steel) is carried out by the finite element analysis software Abaqus.

At present, for coal washing plants and raw coal or coal gangue in shafts under 2000 tons, traditional non-adjustable mineral sizers often face the problem of insufficient production or large size models, resulting in insufficient installation space or substantial increase in cost. The existing adjustable crusher due to the small adjustment range, can not meet the material changes caused by the discharge can not meet customer demand or insufficient production phenomenon, market variability can not flexibly respond to the lack of competitive advantages, resulting in high input costs, limited in

Apron feeder is widely used in the product classification of mining, building materials, transportation, energy, chemical and other industries, apron feeder is the equipment on the crushing and screening machine group. In the production process, the plate feeder can evenly, regularly and continuously feed the bulk and granular materials from the storage bin to the receiving device, which is mostly used in the sand production line. So what are the precautions for using the plate feeder?

The problems of sidewall belt conveyor, such as bad working environment and waste of materials, are caused by running vibration, deviation and sidewall belt conveyor. The conventional treatment methods are as follows: Manual cleaning, flat belt covering on the guard belt and scraper recovery.

Different types of machines handle materials differently. Take the mineral sizers, for example. The shape of the strong mineral sizers roll is coarse and fine toothed roll. The toothed roll is suitable for rough and medium crushing of brittle and soft materials. It is widely used in many fields such as mining, chemical industry and construction.

The traditional crusher (jaw crusher, rotary crusher, anti-mountain crushing and hammer crusher, etc.) relies on the work: the impact pressure applied to the broken material when the parts are moving is broken, the machine is bulky, low efficiency, high energy consumption, these shortcomings limit the improvement of the crushing capacity of the crusher, and can not meet the needs of coal mine production. Recently, the domestic crusher suitable for high-yield and high-efficiency Wells with large crushing capacity, mainly rely on imports, from the 1990s, a large number of foreign companies intro

During the operation of the raw material preparation system in the cement plant, the sealed apron feeder repeatedly stops, resulting in the shutdown of the raw material system, which has a more passive impact on production. Especially with the increasingly strict environmental control, the shutdown of the vertical mill system will lead to fluctuations in the gas emission data of the rotary kiln system, and even exceed the control standards, resulting in the rotary kiln having to reduce production or even stop the material, which seriously threatens the continuous operation of the entire clinke

As a kind of feeder, apron feeder has unique advantages, compared with other conveyors, it can load, can withstand larger bin pressure, and can also withstand the impact of large materials (in order to protect the equipment, a layer of material pad must be laid on the trough plate before starting the machine, so that the material can smash the material), which affects the product quality and service life. Manufacturing quality, material selection and heat treatment of key parts, etc. The following content on the apron feeder key parts of the material selection and heat treatment do some instru

The mineral sizers proximity switch is a kind of position sensor with switching output, which can be divided into inductive and capacitive according to the working principle. The inductive proximity switch is composed of LC high frequency oscillator and amplifier processing circuit. The metal object is used to generate eddy currents inside the object when it is close to the oscillating induction head that can generate electromagnetic fields.

Mineral sizers are suitable for the crushing of medium hardness materials such as limestone, slag, coke, coal and other materials in the cement, chemical, power, metallurgy, building materials, refractory and other industrial sectors.

Apron feeder is widely used in the comprehensive treatment of domestic waste, suitable for materials with large processing capacity and a lot of entanglement, and has achieved results in the extraction of entanglement, homogenization, broken bags and other problems, which has improved the technical level of domestic domestic domestic waste separation, and accelerated the pace of development of domestic waste pretreatment and post-treatment.

The working environment of open-pit coal mine is harsh. During the working process, under the influence of pulverized coal accompanied by materials and pulverized coal produced by secondary crushing, the bearing labyrinth seal and lip seal fail, resulting in pulverized coal entering the bearing cavity, hindering good bearing lubrication.

The raw material grinding system of cement plant uses limestone, clay and copper tailings to feed the ball mill, and feeds with apron feeder. The materials of the three components are respectively sent to the apron feeder through the bar gate, and then fall to the belt scale through the apron feeder trough. The models of the three apron feeders are BL1000x4000mm. In the early stage of trial production, due to the difference in the properties of each component, there were some problems in the belt scale during blanking, and the problems were solved after transformation.

Mineral sizers, as the core equipment of mobile crushing station and semi-mobile crushing station in semi-continuous mining technology system of large open-pit mine, are widely used in mines. The performance of semi-continuous mining technology system depends largely on the crusher.

The crushing box of the mineral sizers general structure is assembled by steel plate, using type 80 channel steel as the base of the equipment. The bottom seat of the crushing box is connected by bolts, and a certain fastening device is adopted after the bolts are tightened. In the design, all parts of mineral sizers will be optimized as a whole, and the reduction mechanism and the crushing box will be made into an integrated form, which will improve the integrity and also improve the sealing. The gear shaft is adopted in the form of semi-exposed gear shaft, and the upper cover and semi-expose

In mining sizer is one of the most important components, especially in the mineral processing link crusher production costs will account for nearly 40% of the total cost of mineral processing, so in the design and manufacture of the crusher should actively do a good performance analysis of the crusher.

Apron feeder is generally divided into heavy, medium and light three, is commonly used in concentrator feeding equipment. The lightweight apron feeder is a continuous feeding machine, suitable for short distance delivery of bulk materials with feed size below 160mm. In the mining, processing plant, chemical industry, cement, building materials and other departments, it is widely used from the storage bin to the crushing, transportation and other machinery for uniform continuous feeding.

Apron feeder chain transmission is a transmission mode that transmits the motion and power of the active sprocket with special tooth shape to the driven sprocket with special tooth shape through the chain, which can form a circulating transmission loop. It is a common transmission mechanism in the mechanical field. In the actual application process, the chain drive may be affected by external factors and reverse, which occurs in some devices such as apron feeder, which will cause irreversible damage to the chain itself and the transportation of materials, so a device to prevent chain reversal

Mineral sizers is mainly composed of gear box, frame part, fixed roller, movable roller, linkage device and so on. The toothed crushing plate is the main part of the fixed stick, and the toothed crushing plate is in direct contact with the ore, which requires the high hardness of the toothed crushing plate. Therefore, the tooth crushing plate is selected to contain chromium high manganese steel

With the demand of the limestone market, the demand for different particle grades is high, so the block ore rate can only be increased from the mining process, but the generated block has increased than in the past. The underground coarse crushing is set at the bottom of the high and deep ore pass, and the ore is sent to the crusher by the heavy apron feeder.

Mineral sizers is one of the main equipment in the production process in basic industrial sectors such as raw materials, power and coal, used to break raw ore or materials of a certain size to the required size. According to the particle size of the material and the size of the product, the crushing process can be divided into coarse crushing, medium crushing and fine crushing, and the toothed roller crusher is more suitable for the coarse crushing and medium crushing of the material.
