Applications | Expertise You Can Depend On | MPS
The majority of our built environment is formed from raw materials extracted from the earth, and in order to produce a usable end-product, the rock or sand and gravel has to be crushed and screened into various size categories. MPS crushing and screening equipment is designed to take raw feed and reduce them to usable aggregates sizes.

Sand as raw material – a scarce commodity?
Larger grain sizes than coarse sand are called gravel or chippings (from the crushing of natural stone). Gravel sizes are also subdivided into fine, medium and coarse. According to the usual conventions, material that is larger than 63 mm is called stones while anything larger than 200 mm is …
A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
Due to the small proportion of fractions smaller than 2 mm, the double-roll crushing technology with special crushing tools is excellently suited for the production of aggregates for concrete. For feed grain sizes of e.g. 22/100 mm, a product grain size of less than 22 mm can be produced with a sand content of between 20% and 25%.

Aggregate is a widely used building material in modern engineering. In general, the aggregate is divided into coarse aggregates and fine aggregates. The fine aggregates with a particle size below 5mm are also called sand. The particle size above 5mm is called coarse aggregate, which is often called stone. Camelway has years of experience in producing sand and gravel aggregate equipment.

Ore, Rock & Aggregate Screening (Complete Guide)
Effect on screening of the particle distribution of the feed. The particle distribution of the feed has an essential impact on purity. See three examples in figure 1. In each one of them the efficiency is 90 %, but the undersize proportion of the coarse fraction varies (3.2 %, 9.1 %, 23 %). Effect on screening of the chosen screen hole size
Raw materials pass through a vibrating screen box that contains different screen and mesh sizes. The material falls through like a sieve, and each rock size falls onto an attached conveyor, which stock piles each product, organizing them at the end for hauling. Screening can be used to create sand, gravel, crushed stone, coal, and topsoil.
Classification of Aggregates Raw Materials
The aggregates row materials are natural stones, which are mainly consist of three kinds of rocks: sedimentary rock, igneous rock and metamorphic rock.. Sedimentary rock: limestone, sandstone; Igneous rock: andesite, granite, diabase, tuff, and basalt; Metamorphic rock: quartzite, gneiss, and marble. Gravel. 5-1 gravel: the particle size is 5-10mm. 12 gravel：the particle size is 10-20mm
Extraction of Aggregates Process
A conveyor draws raw material into the processing plant, where it is washed to remove unwanted clay and to separate sand. Sand separated during processing is dewatered and stockpiled. Gravel then passes over a series of screens that sift the material into different sizes.
The three types of crushers most commonly used for crushing CDW materials are the jaw crusher, the impact crusher and the gyratory crusher (Figure 4.4).A jaw crusher consists of two plates, with one oscillating back and forth against the other at a fixed angle (Figure 4.4(a)) and it is the most widely used in primary crushing stages (Behera et al., 2014).
