The first Gearless Mill Drive (GMD) with a power of MW was installed 1969 in a cement milling process in the cement plant Le Havre in France. In the first few years, the GMD was only used in the cement industry. The GMD is also known as "wraparound motor" or "ringmotor". Almost 25 years later, the first GMD with MW power
At a minimum of 100mm thick, each ten square metres will use a cubic metre, roughly 2¼ tonnes, of concrete/mortar, and as a cementbased material, it will be going off from the moment it is prepared, Consequently, this method best suits those gangs confident of laying flags accurately and rapidly.

In the cement industry, a ball mill for this application is called a Preliminator mill. Con grinding medium is an improved type of ball grinding media which offers more surface area per unit of weight, and has found extensive use in the grinding of cement clinker.
Cement ball mill is an efficient tool for fine powder grinding. It is mainly used to grind the clinker and raw materials in cement industry and also can be applied in metallurgy, chemical, electric power and other industries to grind all kinds of ores.
Look at the asphalt millings. Determine if it has a lot of fine material or if the material is coarse. For coarse material, use an added emulsion percent of to 3 percent. For fine material, use an added emulsion percent of 3 to percent. Emulsion is an additive that contains suspended droplets of asphalt in water helping to bind the mix.
