For large banana screen.

Apron feeder is a kind of industrial equipment commonly used in industrial production, which has a broad application prospect. Can be widely used in coal, mining, chemical, cement, building materials and other industries. As a kind of heavy feeding equipment, apron feeder has the advantages of large processing capacity, wear resistance, and rarely stable maintenance. However, the commonly used apron feeder push head itself cannot sense the pressure of the push head, which is easy to damage the push head.

Material conveying is an indispensable part of today's production process, making great contributions to logistics, medical treatment, garbage disposal, coal mining and other fields. Steel wire rope supporting sidewall belt conveyor can be built in the complex terrain of uneven terrain to complete long distance, high efficiency material conveying, while having the advantages of energy saving and environmental protection.

According to the process layout, coal roller screen can be divided into left installation and right installation. Along the direction of the coal flow, the motor reducer on the left side is the left installation type, and the motor reducer on the right side is the right installation type. Before installation, set the embedded parts according to the requirements of the equipment foundation diagram, and check the levelness of the embedded parts.

In recent years, with the continuous improvement of China's mining industrialization rate, mineral sizers have become rapidly popular due to their advantages of large processing capacity and regular appearance.

Apron feeder is generally divided into heavy, medium and light three kinds, is commonly used in the concentrator feeding equipment, heavy apron feeder is the auxiliary equipment of transportation machinery, the machine in the large concentrator crushing and grading workshop and cement, building materials and other departments, as a silo to the primary crusher continuous and uniform feeding.

The bottom of the chain plate of the heavy duty apron feeder used in the existing mine is provided with more than 200 independent wheel support components, each wheel support component is provided with 2 sets of bearings, and the retaining edge of the wheel lift chain plate.

In the field of industrial production, mining, crusher has a very wide range of applications, including mineral sizers set roller

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
