一、Multi-roller screening dust collector：

Multi-roller screening dust collector It is a necessary equipment for raw material screening and dust removal in straw clean pulping process。Suitable for the screening and dust removal process of straw and wheat straw。The purchased wheat straw and straw will be mixed with a lot of mud, sand, dust and other sundries，If these impurities are not screened out, the ash content of the fiber will be unqualified, and the equipment for subsequent processing will be damaged。It will also affect the factors of high ash content and unqualified quality of the fiber.

二、Input raw material requirements and working principle：

It is required that the length of the input raw materials is between 3-8 cm, and the grass is cut by the grass cutter and sent directly to the multi-roller screening dust remover. This equipment is generally composed of 4-6 groups of turning rollers, and fork plates for turning and throwing grass are installed around the rollers, which are similar to the horns, so we also call them claw rollers。The bottom of each turning roller is provided with a sieve plate for filtering mud and sand。

The sieve plate is assembled and disassembled with quick plug-in structure design, which is convenient for quick extraction and replacement。Wheat straw material enters the screening dust collector from the feed inlet. While the goat horn roller rotates at high speed and keeps moving forward, the feed is turned over, and the feed realizes the screening and slag removal process in this process。Impurities such as mud, fine sand and dust mixed in the middle of wheat straw are beaten, tossed and separated, and heavier mud and sand fall through the sieve holes at the bottom and are separated from wheat straw raw materials。Very fine dust is sucked out and separated by the air-induced dust removal device at the top。Fine dust enters the pulse dust collector of dust separation equipment to collect purified air and then is released at high altitude。Clean wheat straw is thrown into the belt conveyor from the horizontal discharge port，Enter the next process。

三、Equipment characteristics：

Large production capacity, uniform straw screening, good dust removal and purification effect and low power consumption.，Fully enclosed studio, so that there is almost no dust in the production environment, so that workers have a comfortable working environment。Ensure the sanitary conditions of the production workshop.
