Cement - Cement - Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.

Cement - Cement - History of cement: The origin of hydraulic cements goes back to ancient Greece and Rome. The materials used were lime and a volcanic ash that slowly reacted with it in the presence of water to form a hard mass. This formed the cementing material of the Roman mortars and concretes of 2,000 years ago and of subsequent construction work in western Europe.
Manufacture of OPC cement. Majorly there are 5 steps involved in the manufacture of OPC cement, 1. Crushing and grinding of raw material. In the first step of the manufacture of cement, the raw materials are crushed and grinded into small suitable size particles.

It's a key equipment for grinding materials, widely used in powder-making production line such as cement, silicate sand, new-type building material, ore dressing of ferrous metal and non-ferrous metal, etc. Do your know how does the raw mill work in the cement plant? This paper mainly introduces the raw mill in cement plant.
The choice of composition of materials mixture with useful components generally is determined by plant’s geographical location and delivery of raw materials. The only common feature in all cement production plants is the difficulty of grinding the source material as the material is hard enough and has high abrasiveness.
The cement manufacturing process starts from the mining of raw materials that are used in cement manufacturing, mainly limestone and clays. A limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km.
It can not only greatly shorten labor time and labor intensity, but also reduce material working hour consumption. Users can adopt different disposition forms according to the type and size of raw material and the requirement of finished material. In concrete aggregate processing line, the work of the portable concrete crusher for sale is crushing.
