The patented Combi-Vent feeder increases throughput and also contributes to a uniform mixing of raw and return material. The vertical arrangement of the rollers, in combination with the unique nip control, ensures uniform density and bucket volume. The unique control concept makes it possible to operate the nip with an accuracy of +/- 0.1 mm.
The pressure plate aperture range is usually between 3mm-8mm. The minimum diameter of feed pellets can reach 2.5mm. The smaller the processing diameter of feed pellets, the smaller the output. The number of pressure rollers is usually two rollers, three rollers, and four rollers, and the more the number of pressure rollers, the greater the output.
The different fibres are fed continuously into hoppers. The principal components of the hopper feeder machine are shown in Fig. 4.8.The flow can be measured by the height of the blend in the hopper raw material compartment, assuming the density of the material and the rate of feed of the fibre components are constant during processing.

Vertical roller mill is a kind of grinding machine for cement, raw material, cement clinker, slag and coal slag. It has the features of simple structure and low cost of manufacture and use. Vertical roller mill has many different forms, but it works basically the same. All of these forms of machine come with a roller (or the equivalent of ...
The main function of the first mill is to remove the majority of the water. The second mill then aims to reduce the moisture content to a satisfactory level. The pressure feeder in a six-roll mill performs a similar function to the first dewatering mill and so, where a six-roll mill is used, a single dewatering mill should be sufficient.

The friction force has important influence to the pelletizing process of sawdust pellet mill. One of the factors to influence the frictional force is the positive pressure of press roller on ring die. Positive pressure is caused by the integrated motion of distance between press roller and ring die, extrusion force of raw materials on ring die.

Roller mills use pressure and friction for size reduction of raw materials. Material in a rotating grinding table is crushed and ground beneath stationary hydro-pneumatic rollers. Ground material spills over the edge of a lower retention ring where it is carried by a rising gas stream to a classifier on top of the mill.
Cut the raw materials into powder. The ideal size is 2-5 mm. Dry the powders of raw materials to less than 10% water content. Feed the prepared powder for pelletizing through the conveyor belt. Pellet production. In the pellet press machine, the raw material is squeezed through the holes of the ring die with a diameter of 6 mm, or 8 mm or larger.

Gelatinization occurs by mechanical means such as grinding, pressure, and by hot water. Soft feed at an environmental temperature of 25°C can be brought to a temperature of 85°C by the addition of 4 to 6 percent moisture from steam. Frictional heat due to passage of feed through the pellet mill adds 2 or 3 degrees of temperature.
Vertical roller mills Vs ball mills has long been a raging debate in the cement industry. In spite of the fact that vertical roller mills have been around for over ten years now and have gradually become the standard as far as cement manufacturing goes, several cement manufacturers still prefer ball mills for cement production when they want to design new grinding plants or a new integrated ...
For raw meal or for pre-grinding in two-step grinding processes The roller press is often used where energy-efficient grinding of large product quantities is required. The two rollers, rotating in opposite directions, exert very high pressure on the material, effectively crushing and weakening the particles (microscopic cracks), so that the ...
