What is the operating procedure for a gel filtration machine?

In daily life, we often encounter items that are relatively unfamiliar to us—such as a rubber‑filtering machine. Many people may never have heard of it, and you’ve probably run into similar situations. When it comes to the actual operating procedures of a rubber‑filtering machine, there may still be some aspects that aren’t well understood. Below, we’ll take a closer look at the operational guidelines. Safety Operating Procedures for Rubber‑Filtering Machines: 1. Before filtration, the machine head must be preheated to the specified temperature. 2. The motor load must not exceed the rated value (160 amperes). 3. During normal filtration, the temperature of the rubber mixture should not exceed 140°C; in particular, the temperature for chloroprene rubber must remain below 105°C. 4. Burnt rubber mixtures must not be filtered, and the filtered mixture must be free of charred particles. 5. Cold rubber cannot be filtered. If cold rubber needs to be filtered, it must first be softened prior to filtration. 6. Do not introduce metallic or other foreign materials into the rubber filter element. 7. It is strictly forbidden to manually push rubber into the feeder or to remove rubber by hand during operation. Structure and Working Principle of the Rubber‑Filtering Machine: 1. The screw nut is made from a special material—38CrMoAl—with a tensile strength exceeding 550 MPa, and its surface has undergone nitriding treatment. Its hardness is no less than HRC 17. Power is transmitted from the motor through a ZLY180 hard‑toothed gear reducer mounted on the screw shaft end, driving a pair of open gears that rotate the screw. The screw’s rotational speed is fixed and cannot be adjusted. For heating or…

Main technical features and production capabilities of gel filtration machines

In today’s era of rapid technological advancement, rubber filtration machines have found widespread application in many fields. Rubber filters are the primary equipment used to remove impurities from silicone and rubber, with most applications focused on filtering silicone and reclaimed rubber. Common models include the 150‑type, as well as the 200‑ and 250‑type machines. The manufacturing process of rubber filtration machines is essentially the same as that of extruders. Structurally and operationally, they can be classified into hot‑feed rubber extruders. In these machines, silicone rubber is fed into the hopper; a screw mechanism advances the material, generating forward pressure that pushes it toward the extruder die. As the silicone passes through a filter positioned at the die, impurities are effectively removed. The overall design of the 150‑type rubber filter comprises five main components: the die head, thrust assembly, feed system, heating unit, and drive mechanism, along with a rigid frame for mounting auxiliary equipment and components. The extrusion section consists of the machine body, screw, liner, and feed port. Its function is to overcome resistance at the die opening, enabling the mixing, filtration, and extrusion of the rubber compound into semi‑finished products with specific cross‑sectional shapes. The die head serves as both the filtration and shaping component of the extruder, converting the spiral motion of the rubber into linear motion and forming the material into various shaped semi‑finished products. Depending on the type of extruded filter product…

Sharing Basic Knowledge About Glue Filtration Machines

How much do you know about rubber and plastics? Nowadays, there are many specialized rubber manufacturers, and mechanical production has become more extensive and diverse, offering a wide range of equipment such as cold-feed extruders, rubber filters, foaming insulation‑material production lines, and rubber roller calendering lines. So let’s take a look at some common questions about these rubber‑processing machines. 1. Why does an extruded semi‑finished product shrink when it is left to stand? During idle periods, the thickness of an extruded semi‑finished product increases, while its length and width decrease. This phenomenon is generally referred to as “shrinkage.” For example, the length of tread compound may shorten by 2–5%. Like expansion, this shrinkage arises from the elastic recovery of the rubber material. When the rubber exits the die, it expands due to elastic recovery; however, during this process, the molecular chains experience internal viscous resistance, requiring time to reach equilibrium. Consequently, while the material remains at rest, elastic recovery continues, leading to further contraction. Therefore, after extrusion, semi‑finished products must be allowed to stand for a specified period—typically no less than two hours for tread compounds to stabilize, but not exceeding 72 hours to prevent surface contamination or deformation caused by prolonged standing. Also, avoid stacking or crowding the parts during storage. 2. What exactly is extruded by a rubber filter machine, and what are its key characteristics? 1) The screw’s length‑to‑diameter ratio is larger than that of conventional extruders, and its compression ratio is also…
