  • Patent number: 6565024
    Abstract: A dispersing device has a container that receives and processes a product to be dispersed and a grinding device with a housing that contains grinding bodies, wherein said housing has openings enabling the product to be dispersed to pass through, an agitating tool arranged in the housing and a first flow-producing device, and wherein the housing and the agitating tool can move relative to one another and at least one shaft protrudes into the housing via a through-opening that allows the product to be dispersed to enter the housing. In order to reliably prevent grinding balls from escaping from the housing or the grinding basket, it is proposed that another flow-producing device be provided in the region of the through-opening between the shaft (21) and the housing (31), which transports the product to be dispersed through the through-opening, out of the container (1) and into the housing (31) during operation and has means to prevent the grinding media from leaving the housing (31).

  • Patent number: 5967430
    Abstract: In order to reduce the conversion and cleaning effort between pre-dispersion by a dissolver (2) and fine dispersion by an agitating ball mill (3), it is proposed to combine both devices in a single container. The casing (31) of the agitating ball mill (3) is in the form of a toroidal annular channel with a central hole (34). The drive shaft (21) of the dissolver (2) runs through said central hole (34) in the agitating ball mill (3). Dispersion may take place in the dispersing device simultaneously or in succession. The agitating ball mill (3) is preferably lowered inside the container (1) along the common axis after a pre-determined time and caused to act on the substance to be dispersed (5).

  • Patent number: 5215263
    Abstract: To improve the process control in a method and a corresponding device for regulating the rotational speed of agitator ball mills which have a grinding chamber with grinding balls contained therein, a rotatably mounted agitator body arranged in the grinding chamber and a drive for the agitator body, the rotational speed n of the agitator body being measured, the torque M of the agitator body is measured and the rotational speed n is so regulated that the rotational speed n, the torque M or the mechanical agitating capacity P satisfy desired values predetermined according to the relationP=2.pi..multidot.n.multidot.M(.pi.=3.141 . . .).

  • Patent number: 5183215
    Abstract: A grinding appliance, intended especially for grinding material in the form of flowable or pasty conglomerates, consists of a housing (1) with an inlet chamber (2), a grinding chamber (3) for receiving grinding balls and an outlet (4). A rotatably mounted agitator body (5) which can be driven by means of a motor (7) is arranged in the grinding chamber. So that the conveyance can be controlled in a simple way independently of the rotational speed of the agitator body, the inlet chamber (2) is preceded by a storage vessel (46) which is equipped with an air-pressure connection (50) and which is sealingly closeable (FIG. 1). Alternatively, a pump can also be inserted in the storage vessel and the air-pressure connection be selectively exchangeable with a return connection.
