Rock Crusher

Rock crusher also named quarry crusher, stone crusher is applied widely in rock crushing plants and rock processing industry. According to the crushing stage, Zenith can supply you primary rock crusher, secondary rock crusher, and tertiary rock crusher. Depending onto the crushers working principle, Zenith rock crusher can be divied into two models: stationary crusher and mobile crusher.

  4. Types of Secondary Rock Crushers
  5. The Environmental Impacts of Rock Crushers
  6. Types of Roll Crushers

Rock Crusher Working Principle

The basic design of most rock crushers is to hold the raw material in a hopper at the top before feeding this to the crushing mechanism with a belt drive or by use of gravity. Once the material is crushed it can be discharged through the bottom opening and it can be processed further if need be.

Newer generations of rock crushers offer portability and on-site stone crushing; improving production by less time lost to transporting material to fixed plants for crushing. Some of the newer models can combine the actions of jaw rock crushers, cone crushers and roller crushers in to one machine as they have a wide range of compression strengths. With technological advances, industry leaders can expect higher efficiency which translates into greater cost savings.

Rock Introduction

In geology, rock or stone is a naturally occurring solid aggregate of minerals and/or mineraloids. The Earth's outer solid layer, the lithosphere, is made of rock. In general, rocks are of three types, namely igneous, sedimentary, and metamorphic. The scientific study of rocks is called petrology, and petrology is an essential component of geology.

Rock Classification

Rocks are generally classified by mineral and chemical composition, by the texture of the constituent particles and by the processes that formed them. These indicators separate rocks into three types: igneous, sedimentary, and metamorphic. They are further classified according to particle size. The transformation of one rock type to another is described by the geological model called the rock cycle. Zenith can supply you igneous rock crusher, sedimentary rock crusher, and metamorphic rock crusher for sale.


Igneous rocks are formed when molten magma cools and are divided into two main categories: plutonic rock and volcanic. Plutonic or intrusive rocks result when magma cools and crystallizes slowly within the Earth's crust (example granite), while volcanic or extrusive rocks result from magma reaching the surface either as lava or fragmental ejecta (examples pumice and basalt). Igneous rocks crusher mainly includes jaw crusher, hammer crusher and impact crusher etc.

Sedimentary rocks are formed by deposition of either clastic sediments, organic matter, or chemical precipitates (evaporites), followed by compaction of the particulate matter and cementation during diagenesis. Sedimentary rocks form at or near the Earth's surface. Mud rocks comprise 65% (mudstone, shale and siltstone); sandstones 20 to 25% and carbonate rocks 10 to 15% (limestone and dolostone). Sedimentary rock crushers mainly include limestone crusher, earth crusher, dolostone crusher, carbonate rock crusher, sandstone crusher, shale crusher, siltstone crusher, mudstone crusher etc.


Metamorphic rocks are formed by subjecting any rock type (including previously formed metamorphic rock) to different temperature and pressure conditions than those in which the original rock was formed. These temperatures and pressures are always higher than those at the Earth's surface and must be sufficiently high so as to change the original minerals into other mineral types or else into other forms of the same minerals (e.g. by recrystallization). Zenith VSI crusher is the most widely used stationary crushing equipment in rock processing plants for shaping rocks.


The three classes of rocks—the igneous, the sedimentary and the metamorphic—are subdivided into many groups. There are, however, no hard and fast boundaries between allied rocks. By increase or decrease in the proportions of their constituent minerals they pass by every gradation into one another, the distinctive structures also of one kind of rock may often be traced gradually merging into those of another. Hence the definitions adopted in establishing rock nomenclature merely correspond to selected points (more or less arbitrary) in a continuously graduated series. Rock crushing plant is the whole complete processing line for making industrial rocks in construction and mining industry.
