Concrete batching plant can have various problems because of environment change. For example mini batching plant, due to the cold weather in winter portable concrete mixer, the components of concrete batching plant are easy to have failures.Henan Daswell Machinery is a professional manufacturer of mining machine for almost 30 years in China. We are dedicated to supplying our customers with best service and products, our major products include:concrete mixer,diesel cement mixers (for sale),Commercial Concrete Batching Plants,If you are interested in our products, please contact us freely: sales@daswell.com Therefore, it is necessary to pay more attention in the using process and check concrete batching plant in time. 1. Pay attention to preventing hydraulic oil from being frozen. Sometimes, if the equipment can not work normally after starting Concrete Batching Plants, you should confirm whether the hydraulic oil is frozen. It is suggested to bake the transmission, filter and main oil pipeline with a blowtorch, and then start the machine once again. If there is no accident, it can wor normally. 2. If there is gas circuit blocking phenomenon, open the air cylinder. If there is no gas discharged, you should take apart the gas circuit between concrete batching plant and gas control valve. If there is gas discharged, it indicates that the pump can work properly. In winter, the moisture in the gas circuit will be frozen after stopping working, which will cause blocking. So it is necessary to eliminate all the water after each stop. 3. If the oil is diesel, it is also easy to be frozen. Replacing it with low freezing point diesel can solve this phenomenon well.
