Many users usually ignore the importance of materials when choosing a trommel machine, so the trommel machine cannot achieve the ideal screening effect and service life, so how many kinds of materials are there for the trommel machine? What are the differences between these materials? Today we will give you a brief introduction!
The materials of the trommel screen separator mainly include carbon steel, stainless steel, and plastic. The details are as follows:
Carbon steel material: Q235 (including Q235-A·F, Q is yield strength, A is quality grade, F is boiling steel).
The structure of the carbon steel trommel machine is mainly:
1. Full carbon steel;
2. Stainless steel + carbon steel (the base is carbon steel).
It is one of the common trommel machines, and its main features are low price and excellent process performance (such as weldability and cold formability). It mainly does not have much special requirements for the materials to be screened, and is suitable for the screening of some construction powder particles. It does not have too strict requirements on the material, but only achieves the purpose of fine grading, and the style can be designed according to the actual situation on site.
Stainless steel material: 304, 304L, 316, 316L (commonly used stainless steel material).
The structure of the stainless steel trommel machine is mainly:
1. All stainless steel;
2. Stainless steel + carbon steel (the part in contact with the material is stainless steel).
The trommel machine with stainless steel material is mainly because the material has requirements for the contacting equipment material, so as to prevent the material from being polluted by the contact with carbon steel; the all-stainless steel trommel machine is mainly aimed at food, medicine and other industries, and its use environment requirements are strict. Easy to clean the equipment.
It has good anti-corrosion and anti-rust functions. After internal and external polishing, the surface of 304 stainless steel is smooth and burr-free, which fully meets the standards for the food and pharmaceutical industries.
Plastic material: PP, PVC, PE, PS, ABS (at present, the plastic material produced by our company is only PP (polypropylene)).
The structure of the plastic trommel machine is mainly: plastic + carbon steel (the part in contact with the material is plastic).
Its main feature is anti-corrosion, which solves the problems of chemical reaction and strong corrosion caused by special materials in contact with metal during screening. The parts in contact with materials are made of non-metallic materials from the screen frame, screen mesh, middle frame, sealing cover and net cleaning device, which completely eliminates the chemical reaction of some special materials in contact with metal. Plastic trommel machine is suitable for screening and filtering dry powder or slurry materials in chemical, pharmaceutical, military and other special industries.
