Polyurethane sieve plate is mainly used in industries: coal washing plant, coking plant, mine, river dredging, metallurgy, petroleum, etc. Advantages of polyurethane sieve plate (1) According to the shape of the material, the rubber sieve plate and screen can be designed with different hole shapes. (2) The rubber sieve plate and screen are light in weight, which is convenient for on-site loading and unloading. (3) The rubber screen and screen have greater resistance, which can reduce noise.

 The trommel is a common equipment for organic fertilizer screening. It is mainly used for the separation of finished products and returned materials, and can also achieve product classification, so that the products can be evenly classified. The trommel is a new generation of self-cleaning screening equipment. Screening of solid materials. It has the advantages of high screening efficiency, low noise, small dust, and convenient maintenance. Compost: various kinds of orange stalks, fallen leaves, grass, animal and plant residues, human and animal manure as raw materials, mixed with each other in proportion or mixed with a small amount of soil for aerobic fermentation and decomposing. Retting fertilizer: The raw materials used in retting fertilizer are basically the same as compost, but are fermented under flooded conditions.

The basic component of zirconium sand is zirconium silicate (ZrSiO4), which has a variety of properties suitable for casting raw sand, such as: (1) The surface is smooth, there are few cracks and pits, so the amount of binder consumed is very small. (2) Among all kinds of natural casting sand, its thermal expansion rate is the smallest, and the thermal stability at high temperature is excellent. (3) Not wetted by molten metal. (4) Good thermochemical stability, basically not eroded by metal oxides at the pouring temperature of general casting alloys. https://www.lzzgmachine.com/service-parts/product-knowledge/zirconium-sand-features-and-washing-equipment.html
