▎ 摘　　要

NOVELTY - The apparatus has a water discharging pipe whose one end is connected with the water outlet of a water pump (15). An end of the water valve (12) is connected to a sewage tank. One end of a pipeline (6) is connected with a mixing processor (1). One end of water replenishing pipe (8) is connected with the mixing processor in wall, while the other end is connected between the water valve (12) and water pump. The water replenishing pipe is provided with a water valve (9), feed liquid barrel (2) through a feeding pipe connected to the mixing processor. USE - Raw material pretreatment apparatus for producing graphene. ADVANTAGE - The large scale graphene production raw material is pre-processed by electric control, which greatly saves manpower, material resources and financial resources, shortens the production period and improves the production efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an operation method of raw material pretreatment apparatus. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of raw material pretreatment apparatus. Mixing processor (1) Feed liquid barrel (2) Pipeline (6) Water replenishing pipe (8) Water valve (9,12) Water pump (15)
