2. Mixture ratio of the raw materials

Due to region diversity, the cement and sand are different. According to the national standard ratio of 1:3 and considering the operation of our machine, the ratio is listed as following:

Item	Cement	Sea sand（fine sand）	River sand（middle sized sand）	Lime
For rending	1	1.5	1.5	0.5
For Surface coating	1	3	—	0.5

Remark: the grain diameter should be less than 3mm

Only three persons are required for operation. One person delivers material, one person operates the spraying gun, a third person does the assistant work (for instance: assistant to remove the hose). The whole processes such as water adding, mixing and delivery of the material etc. are implemented by the machine automatically. Compared with the manual operation, it can save manpower, material resources, money and precious time, as well makes the construction quality better and more reliable than the traditional manual operation.
