Extrusion press (Press-EP) is briquetting coal dust, coal sludge, peat, lime, chalk, charcoal, lignin, manure, bird droppings and other loose materials without binders
Our company produces entire line of extrusion auger presses (screw presses) of EP series with different capacity and performance. Depending on the type of raw material, size and power of the equipment performance can reach 10 Tons of finished products per hour per press. It should be noted that presses with this design can briquette virtually any small fraction bulk materials if using the additive binders, which after drying and cooling of briquette determine its quality, strength and resistance to external influences.
There is a long list of materials and substances that are briquetted in screw presses without any additives. Such materials already contain substances, which are released from the material becoming ductile and strong during compression and heat. They act as a natural glue that connects the raw material particles while forming the briquette. Strong compression and high temperatures are achieved by operating of the auger when feeding the raw material into a conical chamber, where extrusion mass goes through the seal and subsequently briquetting through the forming die.
For such materials, the basic requirement for high-quality briquette production is a fine dispersion, which is either a natural raw material property, or is achieved by grinding and crushing by the appropriate equipment. It is enough to mix such small fraction raw material with water to the state of a uniform elastic mass to prepare the mixture ready for briquetting. Using presses EP without using binder additives, producer receives quality briquette production of such materials as fossil coal grades D, E, F, G, K, peat, lignin, sapropel, animal manure, bird droppings, chalk, lime.
For this production, our company also produces all the necessary equipment. These are crushers, mixers, dryers, coolers, etc.
