As a crushing production line, the mobile crushing station is more flexible and convenient than fixed production lines, environmentally friendly and energy-saving. It is a combined mobile crushing system consisting of a crushing system, a feeding system, a screening system, and a conveying system machine. The structural composition system of the mobile crushing station is related to its production capacity, investment price and crushing efficiency. Here is a detailed introduction to the structural composition system and performance advantages of the mobile crushing station?
1. Mobile device.
There are two common methods for mobile crushers: tire type and crawler type. The tire-type crushing station is relatively short, suitable for stable grounds, the crawler ground pressure is low, the stability and passibility are better, and it can walk smoothly in the rugged mountain environment. Both configurations are very flexible and reliable, which can save a lot of time and manpower and material resources costs.
2. Feeding system.
The feeding system of the mobile crusher is responsible for feeding raw materials to the crusher and screening machine at this stage. According to different crushing and screening process, the feeding method is also different. In front of the feed port of the coarse crusher, there is generally an independent feeder. The rock materials mined and arranged from the quarry are fed into the coarse crusher at the rate of quantity. Plate feeder, this type of feeder has a larger feeding granularity; when the granularity is smaller, a belt feeder (a shorter belt conveyor) can be used. When the output is not very large, more reciprocating feeders are used, and when the particle size of the material is small, the vibrating feeder can also be used. In the mobile crusher equipment, this part usually does not have a separate feeding device, but a mobile crushing station combination is generally a feeder + host equipment (crusher).
3. Crushing system.
The crushing system of the mobile crushing station is the heart of the whole equipment. It mainly crushes rocks into various kinds of crushed materials of different sizes. The crushing system consists of crushers with different performances. In most mobile equipment, the coarse crushing section usually uses a jaw crusher. The main advantages of this crusher are high crushing efficiency, high output, good crushing effect, large bearing capacity, and safe and reliable use; when the rock hardness is low. At the same time, heavy hammer crushers are often used as coarse crushing equipment. Because the hammer crusher has low energy consumption and large crushing ratio, the process flow can be simplified. In some cases, it replaces the jaw crusher. In the main equipment of the mobile crushing station, cone crushers and impact crushers are mostly used in the medium and fine crushing section. When the hardness of the material is high, the multi-cylinder hydraulic cone crusher and the horizontal bar hydraulic cone crusher can be used; when the hardness is small, the impact crusher can be used. In the main equipment of the mobile crushing station, vertical impact crusher, vertical conforming crusher and other equipment are used in the sand making stage. This series of equipment mainly uses fine sand to make sand, and the finished product has a good particle size.
4. Screening system.
The screening system of the mobile crusher can classify and select crushed stones of different sizes. In mobile crushing and screening equipment, there are many types of screening machines, which are responsible for different screening tasks. Before the coarse crushing section, it is necessary to set up a pre-screen to separate the smaller particles to reduce the crushing and increase the productivity. Usually, a fixed grid screen can be set to complete this operation. When the under-sieve content of the feed port is high, a vibrating screen should be used. Some vibrating feeders have already set up a screen at the discharge port, which can simplify the structure of the entire equipment. The medium and fine crushing section is mostly a closed-circuit process. At this time, pre-screening and inspection screening should be set. In mobile equipment, in order to reduce the number of screening machines, the same screening machine is often used for pre-screening and inspection screening, and the selected screening of finished materials is often carried out in this screening machine. Therefore, a circular vibrating screen with multiple screen surfaces is usually used.
