摘要:
A mixer is disclosed which allows more effectively mixing and easy maintenance, and can positively and effectively suite every diversified kinds of concrete. An inside mixing blade 18 comprises first and second mixing blade elements 19, 19 each provided with a supporting member 18d for supporting mixing blades 18a. The two mixing blades 18a are each formed in helical configuration and has greater width. The first and second mixing blade elements 19, 19 are inserted to a shaft body 17a as well as a spacer 17c and prevented from coming off the shaft body 17a by a end plate 17b. In inside mixing means as structured above, the inside mixing blade 18 is formed in helical shape of substantially 360° . When any one of the mixing blades 18a is damaged, only the mixing blade element 19 having the damaged mixing blade 18a should be replaced with new one so that the replacement can be simply performed and the maintenance of the mixer 1 is improved.

摘要:
Die Erfindung betrifft eine Mischmaschine (1) mit einem Mischbehälter (3), in dem ein Mischwerkzeug angeordnet oder anordenbar ist, wobei der Mischbehälter (3) in einer Behälterwand wenigstens eine, mittels wenigstens eines Verschlusselementes (17) verschließbare Auslassöffnung (15) aufweist, wobei das wenigstens eine Verschlusselement (17) zwischen einer die wenigstens eine Auslassöffnung (15) verschließenden Verschluss- und/oder Mischstellung (19) und einer die wenigstens eine Auslassöffnung (15) freigebenden Auslassstellung (21) verlagerbar ist. Erfindungsgemäß ist eine Sicherungseinrichtung vorgesehen, die bei einem, wenigstens bereichsweise in die Auslassstellung (21) verlagerten Verschlusselement (17) die wenigstens eine Auslassöffnung (15) unter gleichzeitiger Freigabe des Ausströmens des Mischgutes so abschirmt, dass kein Eingriff in den Mischbehälter (3) durch die wenigstens eine Auslassöffnung (15) hindurch möglich ist und/oder die eine Verlagerung des Verschlusselementes (17) von der Verschluss- und/oder Mischstellung (19) in die Auslassstellung (21) blockiert, wenn sich die Sicherheitseinrichtung nicht in einer, die Auslassöffnung (15) für einen Eingriff in den Mischbehälter (3) durch die wenigstens eine Auslassöffnung (15) abschirmenden Position befindet.
摘要:
An apparatus for making concrete is disclosed. The apparatus includes one or more measurement devices that is used to provide controlled quantities of at least cement and sand; a high intensity mixer that receives the controlled quantities of the cement and sand, mixes the controlled quantities of the cement and sand to produce grout, and outputs a flow of grout; and a controller coupled to the measurement devices and the mixer. The controller monitors and controls mixing energy applied by the mixer during mixing. In one embodiment, the mixing energy is altered by controlling the degree of opening of a discharge gate of the mixer. A concrete plant design including such an apparatus is also disclosed.
