Patent DK-4584-A (DK)
Inventor: MATHIESEN MAIT MIHKEL
IPC: C10L10/18
Filed: 1984-01-05
Abstract: An aqueous suspension of a solid fuel, and a process for producing the suspension, are described. The aqueous suspension consists of a highly concentrated suspension of a powdered carbon-containing material having a particle size of at most 0.5 mm and 0.02-2% by weight of at least one additive. The content of solid material in the suspension is 65-90% by weight, preferably 70-80% by weight. The suspension is characterized in that the additive contains a water-soluble surface-active compound which is an ethylene oxide adduct of the following formula HO(CH2CH2O)nB where R is an aliphatic group or acyl group having 10-24 carbon atoms or a substituted aryl group having 12-54 carbon atoms, and n is at least 40, but less than 100, or n is 40-200, in which case the ratio between ethylene oxide units and the number of carbon atoms in the group R is 3.5-6.0, when R is an aliphatic group, and 3.0-5.5, when R is a substituted aryl group. Adding the ethylene oxide adducts after the carbon-containing material has been wet-ground and dehydrated results in an aqueous suspension which is stable, i.e. it does not separate during transport and storage, and which is of low viscosity, i.e. can be pumped with a high content of solid material. Besides the special ethylene oxide adduct, which is preferably added in a concentration of 0.05-0.8% by weight, other customary additives, such as stabilizing agents, antifoaming agents, pH-modified additives and antimicrobial agents, can also be added.

Abstract: A process for preparing a suspension of a powdered carbon- containing material having a predetermined particle size distribution, with a given mean particle size and a given maximum particle size, is described. The process, which involves a comminuting phase comprising at least two grinding steps and combining the ground material with a carrier liquid in order to form the suspension, is characterized by the following steps: (a) the carbon-containing material is ground in a first grinding step, (b) the ground product from step (a) is divided into coarse material having a particle size which is at least greater than the mean particle size of the predetermined particle size distribution, and into fine material which has a particle size which is less than the size of the coarse material, (c) the coarse material from step (b) is ground in at least one further grinding step in order to prepare at least one further portion of fine material whose mean particle size is less than the mean particle size of the final suspension, and (d) a suspension of the combined portions of fine material from the different steps is prepared.

Abstract: 907,124. Automatic control systems for grinding mills. RHEINISCHE KALKSTEINWERKE G.m.b.H. Jan. 2, 1959 [Jan. 4, 1958; Aug. 19, 1958; Oct. 22, 1958], No. 248/59. Class 38 (4). [Also in Group II] Material to be ground is passed through a beater mill and a tube mill in succession and the input to the beater mill is automatically controlled in dependence on the grindability of the material as measured in the beater mill. In Fig. 2, material to be ground is supplied from a storage bin 1 to a charging device 5 for a beater mill 2 (i.e. a hammer mill or breaker plate mill), the output of which is supplied to a tube mill 3. Charging device 5 is automatically controlled by a system 4 to maintain constant the current taken by an electric motor (not shown) driving the beater mill. Since the output of the beater mill 2 is supplied to the tube mill 3 the load on the latter will also be constant despite changes in the grindability of the material, and the arrangement is such that this load is an optimum one for the tube mill. However, in addition, beater mill 2 may be automatically controlled by a system 11 in dependence on the current taken by the electric motor (not shown) driving the tube mill or a bucket elevator 8 supplying the output of tube mill 3 to an air separator 6 which returns too coarse material through a pipe 7 to tube mill 3 and supplies the suitably ground material through a pipe 9. Fig. 6 shows a similar system for controlling charging of the beater mill but in this case part of the output of tube mill 3 is periodically supplied to a classifier 22 in which alteration in the ratio of the weights of particles above and below a predetermined size automatically controls the beater mill 2 through a system 24.
