Roll alignment has two basic components, which includes roll straightness and parallelism in both the vertical and horizontal directions. Straightness is simply a measure of each individual roll in a system to see if it is worn, damaged, sagging, or deflecting under its own weight. Checking roll parallelism in the vertical orientation can be done by either of two methods: laser leveling or adjustment with a machinist's level. This roll alignment tool is simply placed on top of a roller and an adjustment made by turning a small knurled knob to zero the device. This tool can be used for comparing or repositioning rolls in the vertical orientation.
Roll bed presses consist of adjustable bed width, screw mechanism to raise and lower bolster, movable workhead, heavy-duty straightening fixtures and pump electrical specifications. Bed glides in or out on bearings is used to make loading and unloading easy.
Roll compactor is designed for the densification by compacting powder for the pharmaceutical & bulk drug industries in particular and food & chemical industries in general. In roll compactor feed screw is sleeplessly driven through variable frequency controlled speed drive. Mechanical and electrical safety devices are included for operator's safety. A double output shaft gearbox, with step pulley drive and the necessary couplings, drives the rolls. The double output shaft gearbox ensures synchronization of the rolls and an equal distribution of the torque to the rolls. The feed screw assembly can be hydraulically lifted by hand operated hydraulic pump and swung aside. This facilitates easy access and cleaning of all parts having contact with the product. Pre-compaction chamber guides the product to rolls without any slippage or leakage.
