The disposal of grinding sludge regularly costs metalworking companies a lot of money. In addition, they lose equally expensive cooling lubricants, oil or emulsion, which adhere to the sludge and significantly increase the disposal weight.
WEIMA presses offer decisive advantages in the dewatering and compaction of these liquid-contaminated grinding and abrasive waste materials: The throughput is many times higher compared to briquetting. In return, machine wear is significantly lower. Acquisition and maintenance costs are reduced to a minimum. Downtimes approach zero.
With the hydraulically operated WEIMA C.200 press, you dewater and compact wet grinding and drilling sludge to recover expensive cooling lubricants, oil and emulsion. The almost dry sludge can then be disposed of professionally without having to pay additionally for the weight of the liquid.
WEIMA presses are characterized by their simple and robust design. The main components are thus exposed to comparatively low wear. A hydraulically operated cylinder with a press ram moves horizontally and presses the grinding sludge, fed via the hopper, into almost dry, manageable compacts with a diameter of 200 mm. These are ejected via a discharge pipe. The pressed-out liquid can be pumped off from the collecting pan below the machine.
Leaking tipping containers. Sticky coolant on the production floor. Among the biggest challenges are certainly the proper storage, handling and disposal of toxic grinding and drilling muds of all kinds. They can also ignite themselves under certain circumstances and also pose a health risk for employees due to strong odors and the formation of bacteria. With WEIMA presses you separate liquid from grinding dust cleanly in only one work step.
Both technologies pursue the same goal: to dewater sludges as dry as possible and to separate the liquid cleanly.
However, if you compare the design of WEIMA dewatering presses with classic briquetting presses, it quickly becomes visually apparent: machines and plants for briquetting are designed to be significantly more complex. It is true that higher press pressures can be achieved with them. However, practice and experience have shown that for an optimal dewatering the pressing pressure of WEIMA presses is ideal – and does not have to shy away from the comparison with a briquette.
As a consequence, WEIMA presses are significantly less expensive to purchase and, due to the simple design, more wear resistant.
In addition, a pellet with a diameter of 200 mm is significantly larger than a briquette with 60, 80, or even 120 mm. This results in decisive advantages in terms of throughput.
For a long service life, we recommend the particularly high-quality machine variant made of stainless steel. The machine body is thus protected against heavy wear and corrosion such as rust. For less abrasive applications, we offer standard machine variants made of galvanized or painted steel.

Up to 90 percent of the cooling lubricants can be recovered through compression.
Sludges are underestimated by many as a valuable material. Now cleverly save disposal costs – or change from briquetting to dewatering and compaction with hydraulic WEIMA presses.
Due to the high degree of contamination, grinding sludge usually has to be disposed of or landfilled at high cost. Large quantities of raw materials are thus lost and pollute our environment. For this reason, there are now a number of innovative approaches to making the waste product grinding sludge metallurgically usable again. These include the idea of using dry grinding particles in additive manufacturing (3D printing), for example. Depending on how de-oiling processes develop, the classification of grinding sludge as hazardous waste could also soon be eliminated.
