產(chǎn)品簡介

螺桿擠壓造粒機Screw Extruding Pelletizer

詳細介紹

一、工作原理及應(yīng)用范圍介紹 Introduction of Working Principle and Scope of Application

螺桿擠壓造粒機的擠壓形式分單螺桿和雙螺桿。出料形式有前出料和側(cè)出料兩種。經(jīng)混合、捏合的濕物料或低軟化（一般指軟化點小于50℃）物料在螺桿輸送與擠壓作用下從機頭模板孔擠出，然后再經(jīng)過干燥或冷卻得到的顆粒物，從而實現(xiàn)將粉狀產(chǎn)品制成為均勻的顆粒產(chǎn)品。顆粒形狀為圓柱狀，成品顆粒直徑可經(jīng)模板開孔孔徑調(diào)節(jié)和控制。側(cè)出料為0.7-2.0mm，前出料為1.5-12mm，成料率≥95％。

廣泛適用于橡膠助劑、食品添加劑、塑料助劑、催化劑、農(nóng)藥、染料、顏料、日化、制藥等行業(yè)。

The extrusion of screw extruding pelletizer is divided into single-screw and double-screw types, and the discharging form is divided into front discharge and side discharge. The mixed and kneaded wet materials or low softened materials (generally referring to softening point less than 50℃) are extruded from the template hole at the machine head under the conveying and squeezing actions of screw, and dried or cooled to obtain the granule, thus to producing the powder materials into even granule products. The granule is cylindrical, and the diameter of finished granule may be adjusted and controlled through pore diameter of the template, in which the diameter of granule discharged from side is 0.7-2.0mm, and the diameter of granule discharged from the front is .5-12mm. The yield rate is ≥95％.

It is widely applied to rubber chemical, food additive, plastic additive, catalyst, pesticide, dye, pigment, daily use chemical and pharmacy industries.

二、特點 Characteristics

1. 由于粉狀物料在濕態(tài)下完成造粒，使得造粒及其后續(xù)過程（如干燥、包裝等）的操作條件得到大大改善。一般可減少現(xiàn)場粉塵90％以上。

2. 通過造粒，可避免粉體產(chǎn)品易出現(xiàn)的結(jié)塊、架橋等影響使用的現(xiàn)象，同時可避免工藝過程產(chǎn)生粉塵帶來的二次污染，還大大地改善物料性能。

3. 一般情況下，造粒產(chǎn)品的堆積比重都有較大的提高，因此可節(jié)約運輸、儲存、包裝空間。

4. 對多組份復(fù)合、混配的產(chǎn)品而言，造粒可避免各組份偏析，從而真正保證復(fù)合產(chǎn)品質(zhì)量。

1. The powder materials are pelletized in the wet status, significantly improving the pelleting and subsequent processes (such as drying and packaging). In general, over 90% of dust may be reduced in the site.

2. The pelleting can avoid caking, bridging, and other phenomenon easy to be caused and affecting the use, avoid the secondary pollution due to dust generated during the process, and materially improve the material property.

3. In general, the bulk specific weight of finished products are significantly improved, thus to save spaces for transport, storage and packaging.

4. For the multiple-component complex and mixed products, the granule can avoid segregation of all components, thus to ensure the quality of complex products.
