Laboratory Cement Paste Mixer

一、Use and scopeThis machine is one of the special equipments implemented in accordance with GB1346-89. It is a new type of double-rotation and double-speed clean pulp mixer manufactured according to the main technical parameters of GB3350.8. It mixes cement and water according to the standard and stirs it into a uniform test slurry, which is used to measure the setting time of the standard consistency of water and the production of stability test blocks. It is a cement production plant, a construction unit, and a related college Indispensable equipment for research laboratories.

三、Main structure and working principle1.StructureMainly by base 17 Column 16 Reducer 19 Skate 15 Mixing blade 14Mixing pot 13 Two-speed electric motor 1 Composition (see structure diagram)2.Working principleThe two-speed motor shaft is connected by the connecting flange 2 to the worm shaft 6 in the reduction gearbox. The worm wheel shaft 5 is used to reduce the speed of the worm gear shaft 5 to drive the planetary positioning sleeve. The planetary gear 9 fixed on the upper end of the blade shaft completes the rotation movement around the fixed internal ring gear 8 and is automatically controlled by a two-speed motor through a time program controller to complete the specified working procedure of one slow rotation, one stop and one fast rotation.
