The use trick of twin shaft concrete mixer

The starting and feeding of the twin shaft concrete mixer: JS concrete mixer must start with no-load and add material in the operation, otherwise the machine will be damaged due to excessive starting torque. When JS500 concrete mixer is mixing concrete, it must be in accordance with the feed rate of the ingredient ratio and water cement ratio calculation, determine in advance aggregate humidity degree, converse the theory proportion into construction mix proportion, and then according to the construction and JS750 concrete mixer discharge capacity to calculate adding quality of the composition of the material for each time. Loading calculated value should be tested, once determined, strictly enforce it, and maximum aggregate size shall conform to the requirements of the regulations. Forced type concrete mixer is stricter in requirement for maximum aggregate size, otherwise it will produce stuck materials.

Mixing time of concrete mixer for sale: the mixing time of the concrete mixer can be determined according to the slump of the mixture and the capacity of the stirring. In order to guarantee uniform mixing, in general, small and self-falling concrete mixer’s mixing time is 3 minutes, forced concrete mixer mixing time is shorter, about 30 seconds. According to the actual situation of construction, determine it by way of experiment.
