I. Selection and determination of the overall configuration scheme The overall configuration scheme is not an isolated equipment configuration, but takes into account the overall configuration of all production equipment and its units in the plant, mainly focusing on the mutual position, distance and height of the equipment and its units. Poor, reasonable use of terrain, ground height and underground depth, approximate size of the plant and reasonable direction, mode, location and height of materials entering and leaving the plant. The main basic dimensions are given due consideration and the detailed dimensions are not required to be fully labeled. According to the needs and possibilities of specific conditions, appropriate changes and trade-offs can be made to individual devices and facilities when considering the overall configuration scheme. The relative position, distance, height difference, and transfer material relationship between parallel units, upper and lower adjacent units, The self-flow conditions of material utilization (such as the funnel for conveying general ore, the gravity gradient of the trough is 45°~50°, the water content, the powder ore is 55°~60° for a long time, the filter cake is 70°), the direction of the feed and discharge, and the contact between the inside and outside of the plant. Wait for adjustments. The overall configuration plan is not the final map of the plant equipment configuration. The overall configuration plan is formed during the continuous brewing and comparison process. The contents considered and determined generally include the incoming and outgoing points of each unit, the elevation of the discharge point and the device, the material direction, the adjacent upper and lower operations, the relative position of the parallel operation equipment unit, the distance, the height difference, the equipment used for material transportation and transportation, Lifting height and transportation distance, terrain utilization, ground height and underground depth, equipment configuration (such as overlapping, single-layer step, single-row or double-column configuration), maintenance site location, off-site contact and expansion . With the overall configuration, you can design each plant configuration.
As shown in the figure below, the crushing standard cone crusher Ñ„16501 sets, the fine - cut short-head cone crusher Ñ„16502 sets, and the closed-circuit sieve 1800*3600 2 sets. By comparison, the overall configuration scheme is that there is no mining bin and pre-screening before the medium crushing, and the closed screen sieve and the fine crusher are in a stepped configuration. Considering the uniform distribution of the feedstock, a distribution bin is arranged above the closed screen, and the ore is fed to the sieve through the electric vibration. The medium and fine crushing are arranged in a row, and the medium and fine crushing mines share a collecting belt conveyor, which is transported to the distribution bin above the closed screen through three belt conveyors. The closed-screen sieve material is sent to the grinding bin by the collecting belt conveyor 6 to the outside conveyor belt conveyor. The above equipments are all arranged in a factory building, and the medium crushing ore is transported directly to the top of the medium crusher by the coarse crusher discharge belt conveyor outside the plant. This scheme fully considers the direction and mode of feeding and discharge, the location and the height difference. This project has a small footprint, compact and easy to manage. Another option is also considered to pull the closed screen sieve from the medium-sized crushing plant into a separate screening plant. In order to feed evenly, a distribution bin and feeding equipment are arranged above the fine crushing and the sieve. The product on the closed screen is returned to the fine crushing bin by the belt conveyor. The medium and fine crushing ore is transported by a collecting belt conveyor to the distribution bin of the screening plant. The closed screen material is sent to the grinding by the belt conveyor. warehouse. This scheme is more flexible than the previous scheme. The whole system does not affect the entire fine crushing system due to the failure of the screen. The disadvantage is that the plant covers a large area, is scattered, and has no convenient connection. In short, the choice of the overall configuration plan requires a comprehensive analysis and comparison. Before the specific equipment configuration, the overall configuration plan must be determined before the plant equipment configuration can be considered thoughtfully and reasonably. [next]

Second, two sections of open road crushing plant equipment configuration
1. Arranged in the same factory. This is mainly due to the small scale beneficiation plant, equipment not used, and there are several less suitable slopes and other reasons, two-stage crushing and screening equipment can be configured in the same factory building. As shown in the figure below, the original ore is transported from the narrow-gauge mine car or the car to the original mine silo. The first unit consists of the original mine silo, chain-locking feeder, fixed-bar sieve and jaw crusher . The material under the sieve and the crusher are shared by the mine. The collecting belt conveyor is transported to the second unit; the second unit is composed of a vibrating screen and a cone crusher, and the material under the screen and the discharge of the crusher are transported by the collecting belt conveyor 7 to the grinding bin.

2. Arranged in two workshops. As shown in the figure below, the two crusher components are arranged in the factory, and the distance between the two units is long. When the terrain is fully utilized, the longitudinal arrangement along the slope line is small, the amount of earth and stone is small, the structure of the plant can be simple, and the cost is low. But it is not easy to contact. If the site has a suitable steep slope, it can also be placed in the same building. When the number of two-stage crushers is 1 to 2, the two units are opened along the slope line and are respectively independent plants, which is undoubtedly suitable.
