Installation of the High-Pressure Roll Ball Press Machine

Time：May 23,2020

　Our service officially begins the day the customer purchases the product. After mutual communication and negotiation, we’ll finalize and sign a detailed on-site planning proposal. Following this agreement, Hongxin Mining will promptly dispatch its technical team to carry out the implementation according to the specified timeline and exact requirements. Based on the equipment layout dimensions and site plan provided by the customer, as well as the specific planning details requested, Hongxin Mining will swiftly prepare and deliver to the customer an on-site "layout diagram" and "equipment foundation drawing"—typically via fax or mail—for your review. Once you confirm that everything is accurate, we’ll proceed with construction according to the approved drawings.

　　Installation and Adjustment

　　1. Installation

　　When the ball press machine leaves the factory, it mainly includes the following components:

　　1) Pressing machine body. The main unit includes the body, hydraulic components, and is equipped at the top with a motor and a turbine gearbox. If the height exceeds transportation limits during transit, the pre-pressing mechanism and turbine gearbox can be disassembled separately.

　　2) One main reducer unit, with a pulley mounted on the input shaft and one coupling installed on the output shaft.

　　3) One main motor equipped with one pulley.

　　4) One ball-pressing machine control cabinet and one speedometer.

　　5) One vibrating screen machine (including vibration motor).

　　6) Attachments: Dowel pins, V-belts, etc.

　　After the user places an order, follow the instructions in the machine’s manual and carefully construct the foundation according to the user’s own custom configuration diagram (ensure the relative elevations between each component of the ball press machine align with the specifications outlined in this manual). Additionally, leave anchor bolt holes in the foundation—refer to the manual for the exact installation dimensions of these anchor bolt holes.

　　After the ball press machine arrives at the factory, installation should primarily focus on aligning the machine itself. Begin by roughly checking the elevation and levelness, then securely fasten the anchor bolts. Next, use the main reducer as a reference to precisely adjust the elevation and horizontal coordinates, ensuring all anchor bolts are properly tightened. Note that the main motor and the main reducer are connected via V-belts, so you only need to ensure that the motor shaft and the reducer’s input shaft remain aligned horizontally—adjusting the distance between them according to the belt tension. Once this alignment is complete, proceed with secondary grouting to firmly secure the anchor bolts. Minor elevation discrepancies during installation can be corrected using shims. After fine-tuning is finished, apply a cement screed over the base surface. Importantly, this final screeding step must be carried out *after* all anchor bolts have been fully tightened. As for the remaining components, they can be installed according to the overall assembly drawing.

　　2. Adjust

　　This unit has been adjusted before leaving the factory, but further adjustments may still be necessary due to issues arising from on-site maintenance or operational use.

　　1. Adjusting the Production Gap of the Press Roll: During production, there are times when it’s necessary to increase output or enlarge the bite angle. In such cases, you can widen the gap between the two press rolls by inserting a 0.1–1 mm-thick shim between the active and passive bearing housings. Here’s how to do it: First, stop the machine and relieve pressure from the oil pump. Then, move the movable passive bearing housing toward the cylinder side, ensuring that identical shims are evenly inserted at both ends.

　　2. Adjustment of Ball-and-Socket Alignment The ball-and-socket joint is formed by the mating concave surfaces on the primary and follower rolls, which introduces both axial and circumferential alignment issues.

　　A. Axial alignment is pre-adjusted during installation and, generally speaking, requires minimal further adjustment. If adjustment becomes necessary, simply tighten or loosen the bolts on the bearing housing to achieve the desired axial alignment.

　　B. The circumferential alignment steps are as follows: First, loosen the four bolts on the shaft end plate, then remove the 11 M20 connecting screws from the adjustment sleeve. Finally, adjust the M20 x 70 bolt on the adjusting pin to achieve the desired circumferential alignment. If the adjustment becomes difficult, gently rotate the pulley on the main gearbox back and forth by hand. Since the initial setup already accounts for an adjustable clearance equivalent to a spherical socket, any misalignment—no matter how significant—can be easily corrected.
