The next vital part of the system is the control of the motor, which can incorporate a soft start or variable speed drive (VSD) to control the motor starting speed or torque, for example. The VSD model selected was a CFW11 WEG inverter with built in soft programmable logic control (PLC) functions. There were several advantages to this selection, including the standard DC bus chokes to reduce harmonics. The inverter was selected with an output sinusoidal filter to create a nice sine wave, reduce output current and importantly reduce electrical noise

[9] The petitioners who were the existing stone crushing units and most of them had been ordered to be closed down in compliance to the directions issued by the Hon'ble Supreme Court, were to be given first priority in the matter of allotment of sites in the newly carved out zones as provided in Clause 2.1 of the Schedule IV of the Notification. The others are those who have been affected by the newly prescribed siting-parameters and were required to shift to the notified/prescribed crushing- zone and are entitled to have second priority in terms of Clause 2.2 of Schedule-IV of the Notification, as reproduced above. C.W.P NO. 15242 OF 2001 -10- [10] In order to implement the notification dated December 18, 1997, the Haryana State Pollution Control Board issued an advertisement, commencing on 24.08.2001 whereby applications were invited for allotment of stone crushing sites (each measuring one acre) at the notified stone crushing-zones in District Faridabad. Clause 5 of the advertisement stipulated that "allotment of the plots shall be governed by the provisions contained in the Haryana Government, Environment Department Gaz. Notification dated December18, 1997 and Rules/Regulations framed thereunder and amended from time to time". Nevertheless, the Pollution Control Board also inserted Clause 9 which reads as follows :

In 1989, two scientists announced that they had achieved cold fusion, the process of fusing together elements at essentially room temperature to achieve energy production. The hypothesis was that the fusion would produce more energy than was required to cause the process to occur. Their process involved the electrolysis of heavy water (water molecules containing some deuterium instead of normal hydrogen) on a palladium electrode. The experiments could not be reproduced and their scientific reputations were pretty well shot. However, in more recent years, both industry and government researchers are taking another look at this process. The device illustrated above is part of a government project, and NASA is completing some studies on the topic as well. Cold fusion may not be so cold after all

Because of the longer parallel zone in this crushing chamber, a somewhat greater percentage of the product will pass a square mesh testing sieve equal to the close side setting. This will usually average about 65 to 70%, with this percentage varying, depending on the material being crushed. Very frequently, 100% of the product will pass a square mesh testing sieve equal to the open side setting of the crusher

From loading run-of-mine ore to handling concentrates for storage or shipment, managing wear is a constant battle. Mines that work soft, non-abrasive ores are few and far between, so for the vast majority of operations, keeping wear under control is a significant cost item in the production budget. Get it wrong, and the financial implications can be severe: hence the incentive to clad high-wear components with materials that can both withstand continuous abrasion and protect machines and materials-handling equipment made from standard steels
