Single Roll Crusher Models: Type K suited for the size reduction of materials having a compressive strength of 8,000 p.s.i. or less. Materials crushed typically include coal, petroleum coke, lignite and other friable substances. This model is also employed as a lump breaker for potash, chemicals, salts and similar minerals

Ndiema et al. (2002) carried out an experimental investigation of briquetting pressure on relaxation characteristics of rice straw using a densification plunger at differing pressures between 20 and 120 MPa. Relaxation characteristics were taken as percentage elongation and fraction void volume of sample at time t after briquette ejection from the die. Laboratory condition was between 50 and 60% relative humidity. Time t was fixed at 10 seconds and 24 hours after ejection from the die. Both expansion and fraction void volume were noted to decrease with increase in die pressure until a die pressure of about 80 MPa was reached. Beyond 80 MPa compression, no significant change in briquette relaxation was noticed. The study concluded that for a given die size and storage condition, there often exists a maximum die pressure beyond which no significant gain in cohesion of the briquette can be achieved
