Aggregates making plant for coarse and fine aggregate processing

Each of the coarse aggregates and fine aggregates has different purposes, SBM can supply a set of aggregates making plant and aggregates production line to make high quality aggregates. Aggregates play an important role in many industries, such as, building, road, bridge.

 Application and Raw Materials of Aggregates

Aggregate is the loose granular materials in the concrete, which has the function of skeleton and fill. Common aggregate can be classified into coarse aggregate and fine aggregate. The aggregates which particle size is larger than 4.75mm is called coarse aggregate, including gravel, crushed stone, slag, etc. The aggregates which particle size is less than 4.75mm is called fine aggregate, including the fine and medium natural sand, sand, fly ash. These are the main raw materials of concrete aggregate. When mixing, add water and stir the cement into a thin paste. If not do like this, the aggregate will not be formed. Therefore, the aggregate played the skeleton and supporting role in the building.

Aggregates Making Plant

Different aggregates have different effect. Coarse aggregate is often used to make the skeleton of the building and the fine aggregate is more used for fill. Accordingly, the processing equipment for the coarse and fine aggregate is different. SBM aggregates making plant is mainly a variety of aggregates production line, such as: coarse aggregate crushing production line and fine aggregate sand making line. According to different materials and different processing requirements, SBM aggregates making plant can configure different devices on the customized production for customers.

Coarse Aggregate Crushing Production Line

Coarse aggregate crushing production line is the one use crusher as the main equipment. Hardness of pebbles, gravel, slag, and other similar materials is relatively large and so as the crushing difficulty. SBM coarse aggregates making plant specially configured some major aggregates crushing equipment with high performance, including: vibrating feeder, jaw crusher, impact crusher, cone crusher, vibrating screen and so on. Especially the PFW impact crusher can work normally in a variety of harsh conditions.

SBM PFW impact crusher also called hydraulic impact crusher. It is the newest style impact crusher and works with higher efficiency and bigger capacity. Combined with special high-quality cast steel components and durable, interchangeable wear parts, PFW impact crusher owns exceptionally high crusher availability, cost-efficient crushing and low cost per ton. It can simplify the process flow in the coarse crushing line and also shows excellent capability in the fine crushing and super fine crushing line with maximum capacity can be 450tph.

Fine Aggregates Sand Making Production Line

SBM fine aggregate sand making production line is mainly processing fine sand, fly ash and other materials. To make the fine aggregate played the role of filling in concrete, the fine aggregate gradation processing is very important. SBM fine aggregate sand making production line mainly includes vibrating feeder, jaw crusher, impact crusher, vibrating screen, sand making machine and sand washing machine. The sand making machine and sand washing machine played an important role in the fine aggregate sand production line. This series sand making machine use a modular hammer crusher design, when parts worn, by just replace the worn part of the hammer, we can reduce the cost by 30%. The machine uses diamond-shaped impact block, avoiding the impact and wear of material damage the vertical plate.

The unique hydraulic opening cover device makes it more convenient to overhaul the internal machine, replacement parts, saving labor. The sand making plant use unique principle that is rock stone crushing and hot stone to crush the material according to its texture by collision together in the crushing cavity. With this method to make fine aggregate, the output of is not only uniform, cubic, but also greatly reduces the wear and tear of the device. For fine aggregates making plant, the producing sand which washing by the sand washing machine is very clean and with decreased impurity content, perfect sand grain shape, reasonable sand gradation and obviously improved cleanliness.

Standard of Aggregate

1. Fine aggregate should be hard, clean, well-graded. Artificial sand fineness modulus is feasible in 2.4 to 2.8, natural sand fineness modulus should be in 2.2 to 3.0.
2. Fine aggregate in the mining process should be regularly or on a certain number for alkali mining activity test. We should take appropriate measures in potential hazards period.
3. The moisture content of fine aggregate should remain stable. Artificial sand moisture content should not more than 6% and we will take measures to accelerate dehydration when necessary.

International Aggregate Market

In the international aggregate industry, each country has different characteristics. In developed countries, the obvious characteristics of aggregate market are mature and norm and the market prospects are very broad. In some countries like the United States, Canada, Australia, New Zealand and Western Europe, the government regulations have been specific to how to get the land, operating conditions, environmental impact, safety in production and product quality. The overall market direction is to focus on environmental protection, strengthen safety awareness and improve product quality and delivery reliability.
