Comminution - high-pressure grinding for the cement industry including air classifiers especially developed for roller press applications as well as high-pressure grinding for size reduction in the ores and minerals industries; Additionally we would like to highlight our highly innovative Wear Protection systems.

Grinding of cement clinker in vertical roller mills is a technology introduced by LOESCHE which was first used in 1935. Almost 30 years ago LOESCHE introduced the first vertical roller mill to grind both, cement clinker and granulated blast furnace slag, in one process. The concept of M- and S-rollers was established in 1992, which is one of the most cost effective and successful

This enables easy roller removal for maintenance and replacement. The rollers are made with the toughest material, offering increased longevity and efficient raw and cement grinding. This vertical roller mill uses a hydro-pneumatic system to press its grinding rollers against the material bed on the rotating grinding table.

Adoption of specific surface for control of cement grinding began during WWII, and a specific surface minimum of 225 m 2 /kg was introduced into the British Standard in 1947, and remained unchanged until 1989, when it was raised to 275 m 2 /kg.

Energy-efficient equipments such as high-pressure grinding rolls, vertical roller mills, CKP pre-grinders, Cemex ® mills and Horomills ® are used at both finish grinding of cement and raw material-grinding stages due to higher energy consumption of conventional multi-compartment ball milling circuits. Multi-compartment ball mills can be classified as:

In the cement grinding process, the vertical roller mill having high grinding performance is applied especially cement grinding instead of the conventional tube mill. For further power saving, external material circulating system is adopted as same

Grinding systems in cement production make up approximately 85 to 90 percent of total plant electrical energy consumption. As vertical roller mills are 30 to 50 percent more efficient than other grinding solutions, they give cement plant owners a great opportunity to. maximise productivity and minimise operating costs.

Grinding machines are indispensable equipment in cement plants. In the process of cement production, the cement plant needs to complete the grinding of pulverized coal, raw meal powder, and cement products. The purpose of grinding is to increase the specific surface area of the material and reduce the particle size of the powder, so as to achieve the activity required by the

The newly developed MVR roller mill for grinding cement raw material, cement clinker, and additives with an installed power of up to 12000 kW was specifically designed to meet those needs. Large cement plants can now be designed with the one-mill concept for both raw material and cement grinding.

Raymond mill is also called Raymond roller mill. It is a new type of high-fineness grinding mill with high efficiency and closed circulation, which can completely replace the cement ball mill. This kind of machine is commonly used in cement plant for raw materials fine grinding, such as limestone, coal, gypsum, etc. Under normal conditions, these materials’ Mohs hardness should

The HPGR (high pressure grinding rolls/rollers) is the core equipment of the high pressure grinding process. The machine reduces particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them. This forces the rocks against each other and compresses the feed’s density to 80% of its solid

A roller press is installed in front of grinding installations to cut down energy consumption in the grinding unit. Installa-tion of a roller press before rolling mill or cement mill in cement plants is now becoming a common feature. In a roller press, clinker material is subjected to extreme pressure between opposing rollers for a short time

The characteristics of vertical mill: 1) High grinding efficiency; 2) the maintenance is convenient, and the maintenance can not be stopped; 3) Each roller is an independent system, there is no connection between the grinding rollers, and the maximum dynamic load is only related to the quality of a grinding roller;

For composite cement production, the roller mill permits the simultaneous grinding and drying of large amounts of moist additives. For drying the additives and for specifically directed dewatering of the sulphate bearer, the mill can be heated with hot gas from a hot gas producer or with exhaust air from the clinker cooler.

TAVERO™ VM grinding aid additives help stabilize vertical roller mills (VM) during production by reducing water injection requirements and cement pre-hydrati

With roller press grinding cement grinding mill, also has the problem of low temperature ratio. So, with roller press for cement finish grinding, is more suitable for the grinding of cement clinker is inert, without too much of the plaster of Portland cement, lest produce cement retarder.

Material is picked up by plows and directed between the roller and ring where it is ground using a combination of attrition and impact. When the material is ground to the desired fineness, it is sized and discharged from the mill via a screen for semi-fine grinding or air when fine grinding.

Upgrading from a conventional grinding system can, in some cases, more than double your production capacity, while also reducing specific energy consumption by 30 percent. In ball mills, for example, less power is required to produce finished cement from Hydraulic Roller Press-pressed material than from un-pressed material.

Grinding-drying of raw materials with moistures exceeding 20% » Target fineness degrees of 60 to 100 ˜m Cement raw material grinding //Depending on the requirement, cement can be produced by grinding cement clinker with gypsum or with several extenders either in common or separately and, in this case, by mixing the finely ground products
