Small aggregates crushing machine

Aggregate production line: aggregates are the simple elements from the concrete

Aggregate fundamental production status within the concrete structures

1. There's a massive want volume, per cubic metre of concrete is about 1.5Cubic metres of aggregates;

2. the aggregate top quality directly affects the high quality on the concrete dam.

Coarse aggregate size is divided up as follows:

First grade 5 ~ 20 mm

Second grade five ~ 20, 20~40, 40~80 mm

Third grade 5 ~ 20, 20~40, 40~80 mm

Fourth grade 5 ~ 20, 20 ~ 40,40 ~ 80,80 ?120 (150) mm

2. The fine aggregate fineness modulus controlling, usually

~ two.4

Aggregate production line: aggregate quarry plan

Aggregate quarry production arranging could be the foundation of the aggregate method.Aggregate excellent may be the most significant prerequisite for stockyard option.

1. Principles of planning an aggregate quarry.Strengthen gravel quarry plan need to adhere to the following principles:

1) Meet the top quality of hydraulic concrete aggregate, reserves grading strive to meet the desires of every single style, and should have the essential level of wealth.

2) Optional yard, specifically the primary yard, need to be open, elevation appropriate, huge reserves, great top quality, extended mining seasons, it should be capable to take into account the flood or dry season mutual backup specifications.

3) Select of your recoverable price, all-natural gradation and style gradation closer, with the little variety of artificial aggregate gradation adjustment yard.

4) There is certainly adequate carriage return and nearby stockyard land, and take up less farmland.

5) Pick the mining preparation perform is small, uncomplicated construction stockyard.

2. Gravel quarry organizing preferred method

Optimization on the supply material preparing, that is certainly, from the general construction, take into account limiting storage yard, mining and processing, at the same time as the needs on the whole project requirements overall balance, so that sand and gravel cattle production fees as low as targets. According to the supply material conservancy and hydropower project organizing capabilities, preclude the use of systems engineering theory, dynamic programming, linear programming solutions, the lowest production cost of finished aggregate objective function to project the demand for aggregates, factory settings, can stockyard mining stocks, every processing unit production capacity constraints, carried out many gravel mining sand and gravel processing plants, demand and storage optimization in between disposable feeding quantity.

3. Basic sorts of aggregates (supply)

1) Natural aggregate: low expense, but grading and concrete design grading diverse;

2) Artificial Aggregate: very good excellent, you are able to use the excavation of stone, however the high price;

3) Mixing aggregate: organic aggregate-based, supplemented by artificial aggregate.

4. Wool aggregate mining method

Underwater mining: the excavation of all-natural gravel from the riverbed or floodplain dragline excavators and material acceptable to preclude the sand boat;

Onshore Production: primarily made use of excavators. Shown beneath Shovel excavators, backhoe excavator;Hill Field mining: blasting preclude the use of caverns and deep blasting.

Aggregate production line: aggregate processing and processing equipment

The collected wool aggregate processing, ordinarily through crushing, screening and washing, produced ??in line with grading, removal of impurities artificial sand and gravel. As outlined by the aggregate processing procedure, then consists of aggregate processing plants.

1, Aggregate crushing

Use gravel crushing machinery, gear commonly utilised jaw, cone, influence crusher, and three. Zenith's most up-to-date high-performance gear cone crusher could be the very best aggregate crusher for aggregate crushing.

2, Aggregate screening

For grading, need to screening capture the all-natural wool or mixture following crushing, screening has two hydraulic and mechanical sieving grading solutions. Large-scale plant commonly make use of the multi-purpose mechanical sieving, there are actually two types of eccentric screen: vibration and inertia.

3, Aggregate washing

4, Sand making

After the shunt sewage mortar use the grit box for the initial time washing, then the material enter in to the washing machine for additional cleaning. Artificial sand ordinarily made use of the rod mill for processing.

5, Aggregate processing plant

Massive aggregate processing plants, normally processing machinery and equipments in accordance with method (crushing, screening, washing, transport and stacking) arranged the aggregate processing plant. Among them, plant-based screening operations, said screening floor.

Aggregate production line: aggregate stockpiling

In order to accommodate unevenness within the production of concrete, can be utilised to reserve a certain volume of aggregate yard to resolve the aggregate supply and demand. Just how much aggregate reserves, mostly depends upon the intensity of your production and management level, normally 50%-80% in accordance with the monthly typical peak period regarded as. Flood, when the frozen period that must cease mining, aggregate basis getting stopped preclude the needed level of 20% with the margin considerations. Stockyard kinds and terrain situations, stacking equipment, access to material way relevant. Usually employed forms have stepped, bridge variety, embankment sort.
