G, Lever; H, Dash-Boards; I, Key; a, Dies ; c, Shoes, and 0, Pan; B, Muller; C, Legs; D, Cross-Frame; Openings, The relative grinding capacities of “The Excelsior” Grinder and Amalgamator, of the Flat Bottomed Pan, and of the Conical Pan when properly constructed, are respectively 177, 118 and 132. That is, the respective mullers being of the same diameter, same weight, same hardness, and running at the same velocity “The Excelsior Grinder and Amalgamator”’ will reduce one hundred ond seventy-seven tons of ore, the Flat Bottomed Pan one buodred and eighteen tons, and tbe Conical Pau one hundred and thirty-two tons to the same degree of fineness in the same time. The wear to the Shoes and Dies at their grindtog surfaces in the Excelsior Grinder and Amalgamator, is perfectly uniform, thus securing evenness of reduction to the pulp, as well as steadiness Uniform wear of the grinding plates has been attained in no other than that of the Tractory form—nor of motion to the muller. can it be. Another property of excellence in this machine is that the metal or substance to be amalgamated passes direct from the grinding surfaces into the quicksilver ; thus excluding the possibility of its becoming coated with any foreign substances, after having been hurnished. It is truthfully said “that the Tractory-formed Pan as a Grinder has no equal, and as an Amalgamator no superior,” As a whole, it is far superior to any otber pan in nse. MANUFACTURED AT THE Union Iron Works and Golden State Iron Works, WHEELER & RANDALL, Inventors. .

The constant and increasing demand tor them is snflicient cvidence of their merits. They are constructed so asto apply steam directly into the pulp, or with steam bottoms, as desired. This Amalgamator Operates as Follows: The pan belng filled, the motlon of the muller forces the pulp to the center, where itis drawn down throngh the oe erture and between the grinding surfaces, Thence it is thrown to the periphery luto the quicksllver. The curved plates again draw it to the center, where it passes down, andtothe cireumference as before.
