The tooth roller is the main component of mineral sizers. The existing tooth roller drum and wheel hub are generally cast in one body, and then through the wheel hub and drive shaft set to achieve transmission, but the drum and wheel hub casting structure is complex, difficult to process. At present, there are also instances of processing the wheel hub and the drum separately, but the matching surface of the two is a cone, and the two ends of the wheel hub are pulled tight by bolts, the cone is required to meet high requirements, not easy to process, and the bolts to achieve the connection are

In recent years, with the increasing number of crushing stations and the continuous improvement of production, higher requirements are put forward for mineral sizers cleaning system and daily production.

At present, for the opencast coal mine and the existing crushing station of the opencast mine, after the initial crushing, the material is transported to the secondary mineral sizers by belt conveyor for crushing.

Mineral sizers are widely used in mining, electric power and other industries for their advantages of low power consumption, large processing capacity, compact structure, low vibration, uniform discharge particle size and durability.

Mineral sizers play a final crushing role in heavy medium coal preparation systems, crushing the finished coal to the required particle size of commercial coal. The drive shaft of the crusher and the driven shaft with the same tooth roller part is a square shaft, the inner hole of the tooth roller is a square hole, the shaft hole with the crusher working process.

Small crushing ratio, discharge particle size can not be adjusted. The working principle of mineral sizers consists of the three dimensional space composed of the tooth shape of the two teeth rollers arranged in a cross arrangement to determine the size of the discharge particle. When a small discharge particle size is required, the tooth shape is designed to be small, so that the feed particle size cannot be too large; In addition, due to the existence of a variety of uncertain factors in the on-site material (such as water content, material strength, material size, etc.), it is easy to appea

Apron feeder is a professional feeding equipment, can be widely used in cement, mining, coal, chemical, metallurgy and other industries, with large processing capacity, low operating costs, wear and durable advantages, less wearing parts, under normal circumstances the service life of up to 8-10 years. However, we should pay attention to strengthen the inspection and investigation of apron feeder in the process of normal use. Let's introduce the inspection precautions and maintenance tips about apron feeder.

Steel wire rope bearing sidewall belt conveyor can cross complex terrain, complete long distance, high efficiency material conveying, both energy saving and environmental protection characteristics. In order to better apply this type of conveyor to engineering practice, the paper mainly uses catenary theory to study the uniform contact force of steel wire rope and conveyor belt in the coupling state.

With the country's more and more strict environmental protection inspection, many places have introduced new policies: limiting the development of small mines and encouraging the construction of large mines. The reserve scale of new building stone mines must reach more than 10 million tons, the annual mining scale must reach more than 1 million tons, and encourage new mines with reserves of more than 100 million tons and annual mining scale of more than 10 million tons in the planned mining areas around large and medium-sized cities. This has led to the need to vigorously develop super-large

In the process of using the Apron feeder, due to the material weight and discharge impact, it is easy to cause the deformation of the plate feeder. In the existing plate feeder, the supporting wheel 3 is fixed on the frame through the supporting wheel shaft and the cover plate, and the frame is provided with a brace. Because the force is concentrated in the joint of the cover plate and the supporting wheel shaft, after long-term use, the supporting wheel shaft is prone to tilt, resulting in the sinking of the supporting wheel, making the supporting wheel fail.

Installation sequence Mineral sizers the main shaft of the motor and the input shaft of the working machine should be aligned with sufficient space between the motor and the working machine for the installation of the hydraulic coupler. The footing can be adjusted with gaskets or inclined blocks, etc. The different coaxiality errors and angle errors are required according to the following table

With the development of the overall economy of society, the lubrication equipment industry has also expanded, and there are many different prices and different models of lubrication pumps on the market now. The automatic lubrication pump installed on the mineral sizers is one of them, facing so many products, it can make everyone confused in the choice. Especially for most people who lack relevant industry knowledge, there will always be problems of one kind or another. Therefore, it may lead to some users in the purchase of automatic lubrication pump will always have a lot of problems. Famili

The locking disc of the reducer is a hollow shaft, and the locking area is matched with the apron feeder head driving shaft. With the bolts tightening the locking area, the inner diameter of the cone sleeve is continuously reduced, and the solid shaft is held and the torque is transmitted by static friction force.

Apron feeder is a feeding equipment widely used in a variety of industries, with impact resistance, large processing capacity, wear and durable advantages. Here are some details about the application of our apron feeder to the gold smelting industry

Mineral sizers with its outstanding advantages and characteristics are widely used in coal, mining, chemical, electric power and other industries nearly a thousand kinds of materials, can be used to break coal, limestone, clay, iron ore, gold ore, copper ore, nickel ore, lead and zinc ore, here are some use, maintenance and maintenance and precautions.

China's apron feeder coupling industry was formed in the early years of our country. With the rapid development of China's economy, the rapid development of the machinery industry has led to the development of the coupling industry. From the current stage of development, China's coupling industry has formed a complete industrial system.

The mechanism of the broken material is analyzed and a simple calculation method of mineral sizers production capacity is established. The results show that this method is more accurate, more simple and more reasonable. The production capacity calculation formula provides a reasonable and reliable theoretical basis for the design and series development of mineral sizers, and has universal significance for its series products.

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.

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
