Operating hours: only approx. 400 hours The WEIMA TH 814 is a robust hydraulic briquetting press for industrial applications. It processes wood and biomass waste into highly compressed cylindrical briquettes with a diameter of 80 mm. The machine is designed for reliable continuous operation, offering high energy efficiency and a compact design for easy integration into existing systems. Model: WEIMA TH 814 Briquette diameter: 80 mm Application: wood, biomass, paper, plastic residues Year of manufacture: 2020 Throughput: up to approx. 180 kg/h Hydraulic motor: 11 kW Hydraulic system: automatic operation, suitable for continuous use Weight: approx. 1,800 kg Dimensions (L × W × H): approx. 2,098 × 2,316 × 1,405 mm Hydraulic oil capacity: approx. 250 liters Feed hopper: approx. 1,400 × 1,400 mm The briquette length is adjustable and can be regulated via the feed screw speed. Depending on the material feed into the press chamber, the briquette length varies. The control is managed via a time relay in the control cabinet, which determines the operating time of the feed screw motor. The machine has been used very little and is in excellent, well-maintained condition. Sale due to underutilization. Test run on site possible. Loading on site possible. Original operating manual (Hungarian) available. A German version can be provided by the supplier if required. The integrated hydraulic system features automatic oil preheating as well as an oil cooling function. This ensures an optimal hydraulic oil temperature range, even at low ambient temperatures and during continuous operation. This enables reliable 24/7 operation of the machine. The price is fair, considering the condition and the very low operating hours. Inspection is possible at short notice by appointment. If interested, I look forward to your message.

Kondisi: baru, Tahun pembuatan: 2026, Production time approx. 4-5 months --- Our best-selling briquetting press series + Proven, straightforward technology for extremely low failure rates + 25 years of experience, continuous development, and know-how + Several hundred machines in operation with satisfied customers + Excellent price-performance ratio The hydraulic briquetting presses of the MPP NEM series compact materials such as aluminium, copper, brass, bronze, graphite, and other non-ferrous metals into dimensionally stable cylindrical briquettes. These machines are characterised by a robust construction, ensuring consistent briquette quality during continuous operation. The compaction process is performed without the addition of binding agents, relying solely on hydraulic pressure. Depending on the material, the volume of the input material can be reduced by up to 90%. The standard hopper has a volume of approximately 0.5 m³. Hoppers with larger capacities or special containers for installation beneath existing extraction and filter systems as complete disposal units are also available. Depending on specific customer requirements, MPP NEM single units can be combined to create a complete system. The press’s chip container can be loaded manually, by conveyor belt, via extraction system, or with a tipping skip. For systems designed for fully automated operation, it is advisable to use a lift-tipping device in combination with a crusher. The MPP NEM series briquetting presses are designed for the production of briquettes from homogeneous material. The length of each briquette is 40 to 75 mm depending on the model, and the diameter, according to type, is 50, 65, or 70 mm. For emulsion recovery, the briquetting press can be equipped with a collection tray, allowing coolant, cutting fluids, and lubricants to be collected and recovered. Non-ferrous metal chips up to approximately 20 mm in length are loaded into the storage hopper. A stirrer at the bottom of the hopper prevents material bridging and feeds material into the pre-compaction chamber. In this chamber, a hydraulic slide pre-compacts the material and pushes it into the press block. The main press cylinder then compacts the material against a vertical slide until the set pressing pressure is reached. The vertical cylinder then moves up, and the stable briquette is ejected. Briquette production offers the following advantages: • Reduction of material volume by up to 90% • Emulsion recovery • Cost savings in storage and transportation • Economical disposal • Profitable resale -- Briquetting Press NEM 300 Throughput capacity: up to approx. 200 kg per hour *heavily dependent on material type. - On the last test with aluminium granulate under 5 mm – approx. 186 kg per hour + the recovered emulsion. - On the last test with aluminium shavings under 18 mm – approx. 120 kg per hour + the recovered emulsion.

Kondisi: hampir baru (bekas), The MSP 120 ZK is optimally suited for the shredding and subsequent briquetting of various types of metal chips. The MSP 120 ZK briquetting press with integrated shredder consists of a hydraulic chip press and a pre-mounted shredder, which are precisely matched to each other. This system enables the shredding and compaction of chips produced during turning and milling operations. The volume is significantly reduced, and the briquettes are separated from the coolants (coolant emulsion, oil) that were absorbed during previous machining processes. The plant consists of a feed hopper for loading the material to be processed and an integrated shredder inside, which reduces the length of the metal chips. A conveyor system continuously transfers the shredded chips via a conveyor belt into the hopper of the chip press. There, two augers feed the material into the compaction chamber. The system features a monitored liquid collection tank and a pump. The cooling agents can be returned to the production process. The cycle control is managed via a PLC and an electronic level sensor for monitoring the fill level in the hopper. Optionally, a tipping device for manual loading of the system can be added as needed.
