Background
In the construction and engineering field, "aggregate" generally refers to aggregate used in concrete or asphalt mixtures, and it refers to particulate materials such as sand, stones, etc. used in concrete or asphalt. These aggregates play a supporting, filling and strength-enhancing role in concrete or asphalt mixtures. For asphalt mixtures, aggregate is typically particulate material such as stone, sand, etc. used for road paving. Asphalt mixture is prepared by mixing asphalt and aggregate (such as stone and sand) according to a certain proportion, adding appropriate amount of additive (such as mineral powder and adhesive), and stirring to obtain the required material for road paving. Such mixtures are commonly used for the construction and maintenance of infrastructures such as roads, airport runways, etc. The type and formulation of asphalt mixture will vary depending on the specific engineering requirements and environmental conditions. The strength of the asphalt mixture is mainly expressed in two aspects, namely, the cohesive force of the cementing material formed by asphalt and mineral powder; and the other is internal friction and locking force among the aggregate particles. Thus, the quality of the aggregate often determines the strength of the asphalt mix.
Currently, to save purchase costs and transportation costs, construction units generally use a self-processing method to obtain aggregates. During the process of obtaining aggregate, since some rocks have a flaky structure or are prone to generate flaky fragments, this may cause needle-like particles to appear in the aggregate; or if the crushing equipment is set up or operated improperly, the particles may be excessively crushed to generate flaky particles, and further the problems of unqualified aggregate content, unqualified aggregate water absorption, unqualified aggregate firmness and the like are caused, so that a new aggregate self-collection processing method is needed.

2. The method comprises the steps of carrying out three-stage crushing on the master batch, including primary crushing, namely adopting a jaw crusher to decompose the master batch to be smaller than 200mm, adopting a spring cone machine to carry out secondary crushing on aggregate, and adopting a horizontal bar hydraulic cone machine to carry out tertiary crushing. The jaw crusher can generate high crushing ratio, namely, effectively crush and crush materials to make the materials into smaller particles. The adaptability is strong: the material is suitable for materials with various hardness and strength, including hard rock, ore and the like, and therefore has a wide application range. The discharge granularity of the crusher can be controlled by adjusting the spacing of the jaw plates, so that different requirements are met. The jaw crusher is relatively simple in construction and relatively easy to maintain and repair with respect to other types of crushers. Jaw crushers generally have stable operating characteristics that enable continuous and efficient crushing tasks.

The hydraulic system makes the adjustment and control of the operation parameters of the crusher easier, and the size of the discharge hole can be quickly adjusted according to the needs, thereby meeting the requirements of different particle grades. Compared with other types of crushing equipment, the horizontal bar hydraulic cone machine is relatively simple and convenient to maintain, and the downtime and maintenance cost are reduced. The hydraulic system can provide a stable working state, thereby ensuring the stability and reliability of the equipment. The method is suitable for occasions with strict requirements on the shape and the particle size of the finished product, and can meet the crushing requirements of different types of ores and rocks.
The secondary screening of master batch is carried out by adding a transfer bin before the secondary breaking, arranging a vibrating screen in the transfer bin, and screening out fine materials below 3cm generated during the primary breaking, wherein the primary screening is mainly aimed at ensuring that the spring cone machine for the secondary breaking is in a full-negative state as far as possible while screening out waste residues generated during the primary breaking, and the design of the transfer bin fully considers the safety, reliability, practicability and the like of field operation.
