The Bico Chipmunk Jaw Crusher Model 241-36 WD is designed for the rapid reduction of rocks into granular particles. Rocks are placed into the hopper of the machine and are crushed between two jaws in the interior of the machine. The movement of the jaws not only crushes the rock, but forces the discharge down and out of the machine where it is collected in a metal sample tray. Jaw spacing may be adjusted to grind to as fine as 3 to 5 mm.
The primary use of the jaw crusher is to reduce the grain of the material for analysis or for further processing by other machines (i.e. Spex Shatterbox, Brinkmann Grinder, etc.). Typical uses are to prepare hand-samples of rock for X-ray diffraction, whole-rock analysis, or other analytical work.
The jaw crusher is under the supervision of Dr. Abdul Mehdi-Ali of the E&PS Analytical Geochemistry Laboratory. With prior approval of Dr. Ali, the key to the lab containing the crusher may be checked out from the main office.
Description of the Bico Jaw Crusher
In the description that follows, the numbers in parenthesis refer to various machine parts as labeled on Figure 1. Many parts are not user serviceable or the service of them is beyond the scope of this procedure, and these parts are not labeled or described.
The Bico Jaw Crusher is a shock load crushing device driven by a 220 volt 60 cycle continuous motion motor that is coupled to the crusher by a belt driven pulley system. Because of routine maintenance requirements, the user of the jaw crusher must be familiar with much of the machine.
The feed hopper (1) is located about mid-machine directly behind (when viewing the machine from the front) and above the stationary jaw shield plate. Beneath the stationary jaw shield plate is the jaw cam-lock (3) which is part of the securing apparatus for the stationary jaw (7). The adjustment hand knob (5) is located in the lower front on the right hand side of the machine. On the left side of the machine, directly opposite of the hand knob is the square-head adjustment locking bolt (not shown). An oil cup (not shown) for the adjustment assembly is located on the front of the machine, between and above the hand knob and locking bolt. To the left and right, behind the hopper are two grease caps (6) that grease bearings for the moveable jaw (4), a third grease cup is located further back on the machine in the center. Below the third grease cap on the back of the machine is the spring rod assembly (8), and beneath the spring rod assembly is a second oil cup. Under the machine is a space for the sample collection tray (not shown).
The power control (not shown) is mounted on the wall close to the crusher, and consists of two buttons (red and green). The green button starts the machine while the red button stops it. There is also a breaker box located close to the machine with a clearly labeled, separate breaker switch for the crusher circuit.
