Attack winter concrete mixing plant equipment operation problem

Elite Machinery & Equipment Co.,Ltd | Updated: Jul 18, 2016

The selection of raw materials: cement priority selection of Portland cement and ordinary Portland cement early strength cement in order to improve the early strength of concrete, freezing occurs less frequently. Using an inventory of sand should be given priority because inventories relatively low water content of sand, small block of frost, relatively stable if new sand in winter, should strictly require entry of sand water content (at 4%), to reduce freezing risk frequency adjustments adjust the mix and production, ensure the quality of concrete. While around 60 ° c warm water should be used mixing using antifreeze to make concrete, hydration in the negative temperature conditions is still in progress.

Many investors in early in order to save costs, inadequate facilities, but this job is a big risk in winter, when the temperature is too low, the equipment does not run correctly, not only wasted a lot of manpower, material and financial resources, time, delivery does not affect the company's reputation. In order to ensure the normal operation of the equipment, production of concrete aggregate silo material, additive tank, mixer should be closed and set the hot spot (furnaces, electric heating), operations in the air while an additional electric heating.
