· A highpressure tip is used for nitrogen assist gas cutting. This device is designed to maximize the speed and force at which the assist gas exits the nozzle. Assist gas pressures usually range between 300 and 400 pounds per square inch (PSI) when cutting thick stainless steel. Thinner stainless can be cut with pressures in the lower ranges of 100 to 200 PSI.

HPGR High Pressure Grinding Rolls . Used in mining appliions for the last 30 years high pressure grinding rolls HPGR reduce particles by compressing and crushing the feed between two counter rotating parallel rollers with a small gap between them This forces the rocks against each other and compresses the feed's density to 80 of its solid volume exceeding its
· The feed to roll crushers is usually dry. Moisture tends to clog the crusher and could result in the formation of hard crust, which impairs operation. Hence, dry crushing is preferred. Sometimes, water is added between the rolls, which help to prevent formation of the crust and also to remove the hard cake that tends to form on the roll surface. Wet grinding is usually carried out when fine ...
Grinding was performed in a pilot high pressure grinding rolls (HPGR), with the roll size ×1 m (length × diameter). The feed was homogenized in a drum. The moisture content of samples was adjusted to % wt in a horizontal mixer. In order to provide concentrate with SSA Blaine between cm2 g1, all the samples had
1. The spindle speed is too high or too low. 2. The feed plate feeds too fast, or the pressure at the discharge port is too high. Solution 1. Adjust the speed within the specified range. 2. Reasonably adjust the feeding speed and control the pressure at the outlet. Failure 2: The corn peeling is not clean Causes 1. The output is too high 2. The ...
Installed on top of the 5th roll, the particle size management device directly measures the particle size at two loions on the roll (center and side), without using an indirect layer thickness. Every 20ms, the cocoa, chocolate and white mass are measured automatically and at the same time the settings of the 5roll refiner are controlled. This device offers you the optimal product quality ...
HRC™ Series high pressure grinding rolls (HPGR) TON. High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the ...
