According to the modes of action of crushing force,crusher can be roughly divided into two categories:
(1) crusher;
(2) grinding machine.
So what is the difference between them?

Stone Crushing Industry
Stone Crushing Industry is an important industrial sector in the country engaged in producing crushed stone of various sizes depending upon the requirement which acts as raw material for various construction activities such as construction of Roads, Highways, Bridges, Buildings, Canals etc. It is estimated that there are over 12,000

Introduction
The discrete element method (DEM) was first proposed by Cundall and Strack to model the behaviour of soil particles subject to dynamic loading conditions . Mishra and Rajamani pioneered the application of DEM to grinding mills and demonstrated that despite the fact that the DEM simulations are based on two dimensions (2D), the technique is able to predict the power draw of mills with reasonable accuracy over a wide range of mill diameters . More than 10 years since then, the DEM technique has been successfully applied to ball mills , SAG mills and centrifugal mills.
Introduction
DEM has also been applied to study impact-induced particle breakage. Using DEM simulation of impact breakage of agglomerates and aggregates that are hardened by cement, different parameters that influence the impact fracture have been analysed. In some studies, the finite element method (FEM) is usually adopted to determine stress patterns, and DEM has been used to show crack distributions in rocks under loading. Also, using DEM modeling of the compressive strength and drop weight test, the relationship between strain rate, impact energy and the degree of fragmentation has been determined.
Nine rocks with different mechanical properties were modelled as granular assemblies in the shape of a sphere and/or a cube. Each rock as a single particle was modelled while it was crushed in a laboratory

COLD PLANING
Cold planing, or cold milling, is a controlled and highly productive process by which asphalt or concrete pavement is ground up and removed to a certain depth in order to repair or re-profile pavement surfaces.
Cold planing is used to re-establish pavement profiles. This improves drainage flow from pavement irregularities, such as wheel ruts, washboarding and excessive pavement heights at curbs and gutters. This process can also be used to remove deteriorated pavements for future overlays or be used with a fine texturing attachment to improve skid resistance and be left as a final driving surface.
Pallette Stone — a proud member of the D.A. Collins family of businesses — has completed many cold planing projects, including interstate highways, municipal streets, bridges, parking lots and airports. By maintaining a variety of

TECHNICAL ASSISTANCE
A. Impact and Outcome
10. The impact of the TA will be reduced negative environmental impacts from waste coal heaps in Shanxi Province. The outcome of the TA will be a set of recommended policy measures to increase waste coal use in Shanxi Province.
B. Methodology and Key Activities
11. The TA will (i) provide a comprehensive utilization plan and policy recommendations for waste coal, (ii) introduce advanced energy-efficient technologies for waste coal power generation and a technical due diligence report for a 600-MW waste coal power plant utilizing CFBC technology with supercritical steam parameters, and (iii) disseminate knowledge on advanced energy-efficient technology for waste coal power generation.
12. The activities consist of two components.
(i) Component A: Development of a comprehensive plan for waste coal use and policy recommendations, and introduction of advanced energy-efficient technologies. This component will prepare a comprehensive utilization plan for waste coal for the Pingshuo coal mine in Shanxi Province. It will analyze existing policy and regulatory frameworks and make recommendations on policy measures to promote waste coal power generation.
It will analyze (a) existing technology of 600-MW supercritical CFBC and its key components; (b) thermal design methods, hydrodynamic force calculation methods, technical feasibility of outside-sets of heat exchangers, and antirubbing technology for 600-MW supercritical CFBC chambers; and (c) boiler auxiliary

Coal fields in Arkansas are located in the Arkansas River Valley between the western border of the state and Russellville (Pope County) an area only about thirty-three miles wide and sixty miles long. Until about 1880, most coal mined in Arkansas was used near its original location, often to fuel the fires of blacksmiths. Between 1880 and 1920, coal was Arkansas’s first mineral/fuel output, used especially for locomotives and steam-powered machines, as well as for heating homes and businesses. After 1920, oil and oil byproducts pushed aside the popularity of coal as a fuel, and

About coal crushing breaker:
Crushing refers to the process that the bulk materials are cracked into small particles. Crushing process is decided according to the degree of materials’ grindability. For coal crushing, we need to consider the hardness and humidity of coal mine,

Clay:
The clays are mainly used in making bricks, ceramic wares, cement and also for landfill. In europe countries, clays mainly are divided into Kaolin, Fire clay, Ball clay, Bentonite, Fuller,s earth, Common clay.
Clay quarrying in Malaysia:
There are abundant clay resources found throughout the country. These clays include common clay, ball clay, fire clay, shale, laterite and red earth. Deposits of clays are located in the states of Pahang, Selangor, Terengganu, Kelantan, Perak, Kedah, Pulau Pinang, Negeri Sembilan, Johore and Sarawak. Production of clays in 2007 increased to 28,292,423 tonnes from 25,081,174 tonnes produced in 2006.
In Malaysia, there are many companies which supplies all kinds of clays. RADIANT PROVINCE supplies ball clays. CLAYBRICKS & TILES SDN BHD is the largest manufacturer of quality burnt clay products in Malaysia. The state-of-the-art plant, which is located in Kota Tinggi, Johor produces a variety of burnt clay products ranging from facing bricks, paver, brick veneer to utility and accessory bricks at a capacity of 100 million bricks per annum.
The products consist of a wide variety of colours and textures, ranging from smooth face, bark face, rock face, wire-cut, cobble, tumble and sand blast and the colors from white, cream, grey, terracotta, brown, lavender to many other combinations. As one of the core businesses of Cahya Mata Sarawak Group since 1974, CMS Cement now enjoys the distinction of being an integrated cement manufacturer with seamless delivery enabled by direct access to raw materials, through clinker production and quarry operations.
