LPS-RSM-500 is a refractory and concrete spraying machine for light coating applications with reduced operating and purchase costs. This machine can easily handle all popular types of shotcrete concretes containing different sizes and shapes of aggregates, gravels, crushed gravels, and pebbles up to 12 mm sizes with its unique rotor structure. Improved rotor geometry, high quality steel and rubber plates reduces operating costs due to electricity and air consumption. Special rotor lubrication system increases rubber and steel plates' operating life. Water-proof electrical control cabinet design prevents leakage current and provides operator safety. Phase sequence protection, over and under-voltage protection, over-current protection, and thermal protection are some of the electrical safety features. All electrical parts used for electrical systems, cables, breakers, buttons, relays, etc. are made by SIEMENS Simple and service-friendly consumables reduce maintenance costs and time loss. Without having qualified maintenance personnel to change consumable spare parts, after maintenance no need for any calibration or adjustment. Compact design and small dimensions allow working at low ceilinged places. Plenty of consumable parts with long life and highest quality for low prices.
