1. Project Introduction
Thailand Company owns a light expanded clay aggregate (LECA) production plant. The plant required one set of trammel screen equipment to increase the LECA making quality and capacity. The required production capacity is 5 tons per hour. It is bidding equipment. The technical parameters and model selection of double shafts mixer have not yet been determined.
2. Project Description
After the customer disclosed the technical requirements to us, the technicians from Henan Zhengzhou Mining Machinery Co.,Ltd (ZK Corp) quickly gave a solution according to the customer's existing production situation. The solution includes detailed equipment parameters, shape drawings and layout drawings. The detailed proposal and quick reply from ZK Corp had given the customer a very professional first impression.
After one month weeks of research, discussion, calculation and 3D layout design with the customer's technical staff, the final proposal had been finalized. Meanwhile, ZK Corp’s technician also helped customers solve many other technical problems during the production. Finally, the technical parameters such as screen drum diameter, screen drum length, sieve mesh, main shaft rotation speed, material, structure and power are determined. Mutual trust had been greatly deepened. At the same time, the equipment technical parameters with reasonable price submitted by our company were recognized by the final user side, and finally ZK Corp won the equipment of this bidding section.
After 60 days of production, the trammel screen was tested in the assembly workshop of Henan Zhengzhou Mining Machine Co., LTD., and passed the quality and function test of the third party inspection company in one time. One-time acceptance highlights the Henan Zhengzhou Mine Machinery Co., LTD. "Quality of survival" business philosophy. Make delivery as the contract requirements showing Henan Zhengzhou Mining Machinery Co., LTD. "Timely delivery" commitment to customers.
3. Equipment Parameter
The working principle of the trommel screen is that the transmission device drives the conical drum to rotate through the coupling, and there are different specifications of the screen mesh tensioning in the outer ring surface of the drum; After the finished LECA are fed to the drum by the feed port, they move to the tail of the drum continuously as the drum rotates. The finished LECA with qualified particle size enter the next process through the screen, and the unqualified products are discharged from the tail.
The trammel screen is mainly composed of the drum device, the transmission device, the bracket, the shield and so on. The main structural characteristics are:
1. The reducer drives the roller to rotate through the cross slider coupling, which has the characteristics of simple structure, convenient maintenance, smooth transmission and low noise.
2.Tthe roller device in the circumferential direction is distributed with 6 press blocks to press the screen, to ensure that the screen has enough tension, so as to make it stable and reliable work.
