A piston press system and a test method using the same are used for predicting the roll service life of high-pressure grinding rolls. The method is based on the same comminution mechanism of inter-particle layers compression as the heavy equipment high-pressure grinding rolls to simulate the grinding process of the studded high-pressure grinding roll, realizing that the coverage area of studs accounts for 16% to 20% of the compression surface by disposing tungsten carbide upper studs and lower studs, better restoring the simulation process and effectively realizing the roll service life prediction of the heavy equipment high-pressure roller mill with a small quantity of materials.

A compression device allows for compressing a carbonated beverage container, for maintaining the container in a compressed state, and for releasing the container from the compressed state when desired. In one embodiment, the compression device (100) includes a first frame (101), a second frame (102), a first linking frame (103) and a second linking frame (104). The frames are joined together by hinge connectors (111, 112, 113, and 114), forming a quadrilateral enclosure or compression assembly that accepts a PET bottle. A hinge controller (119), associated with the first hinge connector (111), is operative to control compression and release of the bottle.

This method for manufacturing a high-density strand board enables high-density strand boards to be formed by using about the same press pressure as press pressures required to form strand boards with common densities, so that the high-density strand boards can be produced without using special facilities and equipment. A pretreatment process P2 is performed on strands 5 before pressing. The pretreatment process P2 is comprised of a first treatment process P2a and a subsequent second treatment process P2b. At least one of beating, high-frequency treatment, high-temperature high-pressure treatment, high-water pressure treatment, repeated deaeration and dehydration treatment, and chemical treatment is performed in the first treatment process P2a, and roll pressing or flat press pressing is performed in the second treatment process P2b. A strand board B with a density of 750 to 950 kg/m.sup.3 is formed by using a press pressure of 4 N/mm.sup.2 or less.

A mallet hammer tipping-detipping apparatus may include a press weldment. The press weldment may include a press base and a press neck extending from a surface of the press base. The mallet hammer tipping-detipping apparatus may include a press adapter coupled to the press neck. The press adapter may include a central recess such that a mallet hammer head may interface with the press adapter. The mallet hammer tipping-detipping apparatus may include a tip holder coupled to the base of the press weldment such that the press adapter is positioned above the tip holder. The tip holder may include a seating section in which the mallet hammer head may be positioned.
