Type of Stone Crushing Machine

Stone crushing equipment is required to crush the large rocks into smaller pieces for various construction applications. There are several types of stone crushers such as jaw, cone and hammer crushers.

Crushing stone by hand was a slow, monotonous job fit for convicts, tramps and poor-house denizens until the invention of Blake’s stone crusher in the late 1800s.

Jaw Crusher

The jaw crusher is a machine that breaks large rocks into small pieces by the force of compression between the fixed and movable plates. It is used in stone mining, building materials, metallurgy and highways construction. It can be used as a primary or secondary crusher. The size of the product is controlled by adjusting the throw (maximum amplitude of the swinging jaw). The higher the throw, the more finely the material is crushed; however, a larger throw increases the risk of packing and causes more stress on the jaw plates.

Selection of the optimal crushing equipment depends on a number of factors, such as the characteristics of the rock, moisture, crusher speed and nip angle, method of feeding and the required degree of size reduction. Several computer programs are available for weighting different options, but the ultimate decision must be made on the basis of experience and practical analysis of different sites and conditions.

Cone Crusher

The cone crusher is an efficient crushing machine that mainly consists of two hard metal parts. A relentless back and forth gyration compresses the stone between these two metal parts to crush it into smaller pieces. This type of crusher can be fixed or mobile.

The growing construction activities in Asia Pacific will drive the demand for stone crushing equipments during the forecast period. In addition, increasing government expenditure on the development of roads and highways in developing economies of the region is also anticipated to fuel market growth.

Another major driver for the industry is an increased adoption of waste recycling in construction projects. This is a cost-effective and environment-friendly way of disposing of waste materials. It also helps in reducing the burden on landfills. The rising awareness about the benefits of recycled aggregates will boost demand for stone crushing machines. These crushers help in converting construction waste into reusable material. It reduces the need to mine and process minerals, thus lowering the production cost.

Hammer Crusher

The Hammer Crusher is a kind of machine that can break large stones into smaller ones. It works by rotating a hammer at high speed in the crushing cavity. The material is then crushed by the impact and shearing forces of the hammer. In the lower part of the rotor, there is a sieve plate. The fine particles are discharged from the sieve, while those larger than the hammer size are retained on it to continue being hit and ground by the hammers.

The hammers are made of special alloy material that is stronger and harder on key areas, so they can resist the heavy wear that occurs in this type of machine. This allows the hammers to keep their original shape longer, resulting in higher production and energy savings. The hammers also have better impact and bending strength, which reduces the number of hammer replacements. They are much more durable than the high-manganese material hammers that are prone to cracking, desoldering and out-of-blocks.

Impact Crusher

The impact crusher forces two metal surfaces toward one another to crush the material caught between them. The effect is created by the rotation of a rotor with hammers or blades around a central shaft.

This stone crushing equipment has several advantages: First, it costs less than compression crushers of the same size for a given application. Second, it can achieve a higher reduction ratio than compression crushers. Third, the fact that it produces a cubical product helps many customers meet stringent specifications for their aggregates.

Growing construction activities, steady growth of economies as well as continuous development of roads and highways globally are expected to boost the demand for this stone crushing equipment. Moreover, growing mining activities in countries such as Canada and Russia are likely to fuel the demand for this equipment.
