concrete and mortar plants may be placed on the sites of plains and terraced with a stepped terrain.
Decking layout direction areas on the slope is suitable for mixing low power installations with no operating warehouses aggregate under the scheme with a stop vehicles on the feed hopper when loading feed bins installation is performed directly by road, arriving to the base stock or crushing and screening plant, or when the use ofthe terrain can reduce energy consumption for moving aggregates and cement operating warehouses to the mixing plant, as well as in cases where a radius of transporting the mixture can not find the type of flat pad.
Rational use of the terrain at the location of storage facilities on the upper elevations of the site and mixing plant at lower elevations can reduce the cost of the rise of aggregates and cement.
Master Plans (site) concrete plants can be classified as:
1) the nature of contiguity plants to external communication routes: to the rail, road, water and mixed;
2) Configuration: on the elongated, mostly with the direction perpendicular to the traffic of intra-major axis of the site, and the site approaching the shape to a square;on the extended sites easier to place a large discharge front exhaust deadlocks, arrows, congresses;platform, configuration approaching the square, became widespread in the road transport supply of raw materials;
3) of the internal arrangement of railway lines - a dead-end in the area paths, cross-cutting and circular paths: the paths through area extends in length, with ring - grows in length and width;
4) depending on the profile of the site - on horizontal and terraced: when placing the plant on terraced platforms can reduce energy consumption for moving raw materials from the upper to the lower elevations, but is complicated by the use of rail transport.
General plan concrete and mortar factories can be arranged:
1) with a cross-manufacturing flow is perpendicular to the major axis of the pad;
2) with a longitudinal production flow directed along the major axis of the pad;
3) combined with the longitudinal and transverse direction of the production flow.
layout master plan can be carried out under the scheme separate building with free-standing buildings and block diagram by combining in a common block of concrete batching plant, cement warehouse, bunkers heating, installing vibropomola.The last solution can be carried out mainly through the use of elevators for vertical transport of materials, vertical or inclined at a large angle-speed screw conveyors and pneumatic transport.
Application block scheme makes concrete plant more compact, increases the rate of development, reducing the need for its accommodation site, thus saving on construction volume of buildings and reduces heat loss in winter.The use of block construction reduces capital costs and operating costs.
disadvantage of this arrangement is the need to use placeholders for the equipment less reliable than conveyor belts.Development of conveyor belts with transverse baffles and tube type with locks "lightning" creates the conditions for wider application of the block scheme.
The disadvantage of this arrangement also applies to cargo traffic contiguity external storage facility in a limited area, which worsens the conditions of unloading and maneuvering of railway and motor vehicles.
to reduce the length of conveying bulk materials, in some cases carried out directly abutting individual facilities to the mixing shop.
Location several adjacent mixing units or more sections of a mixing plant, and bunkers ready concrete mixture should be such that the vehicle and railmotor cars ready mix moved smoothly, and are installed on a vehicle buckets loaded from two bunkers ready mix.If it is not the choice of the distance between the discharge port silos, without taking into account the size or placement of tubs vehicles on railway platforms, there can be some decrease in performance as a result of plant peredvizhek during unloading of finished concrete mixture.
significant impact on the size of the site occupied by the concrete plant, have, in addition to the power plant (total capacity of mixing machines), storage types of aggregates and cement.
In large power plants, along with an increase in height and the height of the stacks of storage silos, as well as the concentration of storage facilities, reducing specific area, there are structures that increase the specific area (bademoechnaya, compressor, boiler, etc.).
When linking the general plan should take into account that the location of warehouses in the middle of a factory site less suitable than the extreme, not only in terms of the possible crossing of cargo flows, but also because under unfavorable wind directions dust settles on the mechanisms and automatic mixer.
When burial in the ground air and steam pipelines and cement plants-wire operation is complicated.From accidents, as is often required considerable time to finding breakout space highways.Due to the backwater of groundwater steam line can be flooded with water, which results in heat loss.
When you juice the level of groundwater use trench belt conveyors is impractical because of the trench may be flooded.In such cases, the desired transition to the transportation of aggregates from the warehouse to the mixing plant by road, without creating any ground transport means.
When linking the general plan of the plant should also be borne in mind records and weighting materials.
Usually cars with cement weighed and sealed at the point of departure, but in some cases may be required to weigh-arriving cars with cement.In this case, provide a special weight of cargo turnover at small dead end and a special weight-through path for large cargo flows.
