Adjusting the tension of the mesh belt conveyor is carried out in three steps: Firstly, the parallelism between the drive shaft and the driven shaft is adjusted (the parallelism cannot reach the deviation of the mesh belt conveyor and one side of the teeth is skipped). Then the drive end bearing is adjusted. The sprocket is fixed and the center distance of the sprocket is adjusted. The passive end is tensioned from the loose to the tight sides. At this time, the lower mesh belt is supported by the hand vertically upward until the chain is 50 mm higher than the lower track. Finally, the dead-end bearing and the tension bolt can be fixed.
Water Reducer mainly is used for cement in construction field. Used for and widely for self-cured, vapor-cured concrete and its formulations. At the early stageof application, extremely prominent effects are shown. As the result, the modulus and site utilization can be drastically, the procedure of vapor cure is omitted in peak-heatsummer days. Statistically 40-60 metric tons of coal will be preserved when a metric ton of the material is consumed.The new raw material is researched and produced by ourselves, which is mainly used in theproduction of polycarboxylate superplasticizer products.
Remarkable plasticity: as a condition of blending where amount of cement and collapsibility are fixed aforehand, mixing water can be decreased by 18-28% when it is admised with reinforced concrete at 0.5-1.0%. Ststistically, compression strendth on the 1st day, the 3rd day and the 28th day after single application is increased by 60-90% and 25-60% respectively when it is added at standard blend dosage. As the result, compression strength, tensile strength, bucking strgth and modulus of elasticity will be improved to some extent.
