In 1904, Krupp produced a selfcontained cement mill using a ball mill and their version of the Askham separator in closed circuit, but I think this was never used in Britain. However, from the mid 1890s, ball mills were used in combination with tube mills (see below) and this setup became the normal cement milling installation until 1920.
CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.
Operation and Elements of a ClosedCircuit Ball Mill System . Cement ball mills typically have two grinding chambers.

This plant has 2 lines for cement production (5300 t/d). The ball mill has one component, m diameter, and m length with 240 t/h capacity (made by PSP Company from Přerov, Czechia). The mill's rotation speeds are mainly constant (14 rpm), and there is approximately a fixed oneyear period of changing liners.
The present work is aimed at further understanding of the design studies of feed chute for powdery feed material and truck using FEM and DEM software and to use in the further designs of ball mills. FLS UMS Type Cement Ball Mill In 1893 FLSmidth (FLS) firm acquired the rights to a new mill type, the tube mill, from the French/Danish inventor.
Peripheral discharge ball mill, and the products are discharged through the discharge port around the cylinder. According to the ratio of cylinder length (L) to diameter (D), the ball mill can be divided into short cylinder ball mill, L/D ≤ 1; long barrel ball mill, L/D ≥ or even 23; and tube mill, L/D ≥ 35. According to the ...

The ball tube mill is mainly used for grinding finished products and raw materials in cement plants. It is also suitable for grinding various ores and other grindable materials in metallurgical, chemical, electric power and other industrial and mining enterprises.
Clinkers are ground in ball mills and tube mills after controlled cooling. The cooling rate of clinkers affects the strengthgaining properties of cement. About 35 % gypsum is added during grinding to the cooled clinkers to prevent flash set. Closedcircuit grinding is done in tube mills. A cyclonic separator ensures proper particle size ...
The great range of sizes covered by industrial ball mills is well exemplified by Fig. and Fig. In the first illustration is shown a laboratory batch mill of about 1litre capacity, whilst in Fig. is shown a tube mill used in the cement industry the tube having a diameter of about 8 ft and length of about 45 ft.
Tube Mill Equipment is a kind of grinding equipment, which is usually used for grinding raw materials in building materials, the chemical industry, electric power, mining, and other industries.
This paper deals with multi compartment tube mills as field data of the mills in cement industries [13] are available to confirm the theory with, although the paper does not fully discuss how to design or optimize the individual lengths of the compartments. ...

tube mill: [noun] a grinding mill that consists of a long revolving tube containing flint pebbles or steel balls or slugs and is used for pulverizing (as in cement manufacturing) — compare ball mill.
(The rate of tube mills using the smallest ball of 17 mm was about 10% in the 1979 survey by Japan Cement Association but increased to 80% in the 1991 survey.) Filling factor of grinding media The filling factor of grinding media greatly affects the grinding capacity and power consumption of a mill.
