A user in Zibo, Shandong Province ordered 4 sets of YZYW50-8 fully automatic hydraulic oil presses for deoiling and drying of durenyl in fine chemical industry, with a designed capacity of 30 tons/24h. The specific process flow is as follows: the durenyl slurry with good fluidity processed by the customer's front-end process is stirred evenly in the mixing tank and then transported to the YZYW fully automatic durenyl solid-liquid separation press by a high-pressure plunger pump; the durenyl mixture is filtered out during the pumping process. As the pressing liquid is filtered out, the solids accumulate, and the feeding is completed after the feed pump reaches the set pressure. The YZYW fully automatic hydraulic oil press starts to cold press. After the cold pressing is completed, the finished durenyl automatically falls off into the vibrating conveyor under the oil press, and is transported by the vibrating conveyor to the belt conveyor equipped by Party A, and then transported by the belt conveyor to the crushing and packaging process of the next section.
