Our Onsite Crushing Process. Our crushing process can reduce concrete into gravel-sized pieces often used in road work, structural fill, and landscaping, among many other uses. We can provide you with on-site concrete crushing at your demolition or construction project to produce usable material. Benefits Offered by On-Site Concrete However, cement concrete is a rigid material, due to the large instantaneous impact energy of water pressure equipment, the nonlinear fluid–solid coupling will occur in the process of jet action [11], which leads to more complex crushing characteristics of jet impact concrete.Study on characteristics and prediction model of jet impact concrete

The Portland cement manufacturing process can be divided into 6 steps: raw material crushing, pre-homogenization, fine grinding, clinker production, cement grinding, cement packing, etc. In these processes, we need the assistance of different kinds of cement equipment, such as cement kilns, cement mills, and cement crushers.The roller crushers are used for moist and sticky materials. Generally the machines have to be rigid enough to crush also hard inclusions. As the reduction ratio is only about 5:1 a 2-stage crushing is required in most applications.

Cement production is a highly energy intensive process and the energy consumption of cement industry is nearly 5% of the total global industrial energy consumption. The theoretical energy consumption for producing 1 kg of Portland clinker is about 1.76 Mega joules. The kiln is the major energy consumer in cement making, while The type of cement production process in the studied cement plant is typical dry process Portland cement and consists of three major steps. In the first step, certain portion of clay and limestone are blended together and then the mixture is crushed to form a powder.
