The V-separator is generally used with a pregrinding system (Roller Press). - Applications mainly for raw meals, clinker and slag. - The main objective of this separator is to remove a maximum of fines particles from the Roller Press feed in order to decrease the problems of vibrations. -

The cement production industry is realising the potential of connectivity-based technologies, often referred to as Internet of Things (IoT) technologies. We see it as the convergence of information and operations technology, providing valuable data about plant equipment. Understanding the advanced sensing and data analytics allows cement plant ...

Selection of the grinding system—tube mill, vertical roller mill or roller press and ball mill. They can be examined technically on a case-by-case basis to arrive at optimum solutions for specific projects. 1.9. Differences on account of increase in size of cement plants 1. Cement plants have grown much bigger in size.

the ride-on roller/compactor followed behind to compact the newly laid asphalt. The roller opera-tor made a forward pass with the roller, stopped, and then reversed the machine. The machine had traveled approximately 10 feet when the opera-tor sensed that something was wrong; at the same time, a passenger on the roller alerted the operator

Nowadays many cement factories used modern production technology to increase capacity and quality of cement. In modern technology, they use the equipment, such as a cross belt analyzer manufactured by Gamma-Metrics of USA to find the composition of limestone at the conveyor belts, high-pressure twin roller press, six-stage preheater, and vertical roller mill.

Excessive dynamics in the roller press is often related to wear on the rollers, so the trends identified by the torque measurement are a valuable tool when planning an overhaul of such roller presses. This article was first published in …

building are different from the conventional steel or concrete structures. Glass cannot crack like concrete and it is much more brittle than steel. Aluminum involves many buckling modes similar to but more common than steel. Owing to the low Young modulus of elasticity around 1/3 of steel, buckling and large deflection nonlinear effects

Roller press with ball mill is used to grind the clinker. 3.5 to 4% Gypsum is added to make OPC. To make PPC, up to 35 % fly ash is added to the clinker in addition to Gypsum. Three grades of cement (OPC 43, 53 and PPC) are manufactured and stored in silos.
